The Fronius Ohmpilot minimises electricity and fuel costs

Wouldn‘t it be lovely if you could produce the majority of your required household energy for yourself? And not just electricity, but heating as well? The Fronius Ohmpilot allows you to use surplus energy from a PV system to heat up your water. What‘s more, it can be installed as an add-on – which is exactly what the Samwald family did to their system in Austria.

The existing oil-powered heating system for the six-person household can now be deactivated for the entirety of the summer, thus reducing its usage and extending its service life. This has also lead to reduced fuel costs - a saving of over 430 litres of oil every year.Steinbach Austria

“We decided to invest in a Fronius Ohmpilot because we wanted to lower our electricity and fuel costs, to increase our rate of self-consumption and to reduce our CO2 footprint,” says system owner Stefan Samwald.
Size of installation 4 kWp
System typ Roof-top installation
Inverter 1 Fronius Symo 4.5-3-S
Further products Fronius Ohmpilot, Fronius Smart Meter, Fronius Datamanager
Self-consumption rate

Before installing the Fronius Ohmpilot: 30%

After installing the Fronius Ohmpilot: 61%


The challenge:

  • Preserve the 22-year-old oil heater
  • Reduce energy and fuel costs
  • Increase the proportion of self-consumption

Our solution:

  • Connect the current 3-kW heating element to the Fronius Ohmpilot
  • Optimised energy management with the Fronius Smart Meter

System highlights:

  • Heating cost savings of 336 euros*
  • Annual oil consumption cut by 432 litres*
  • Increase in level of self-consumption from 30% to more than 60%
  • From the end of March until the beginning of November, no oil heating is required to heat water
* Based on 2017 values

General terms and conditions

1. APPLICABILITY

1.1 All deliveries and other services effected by ourselves, Fronius Australia Pty Ltd., (ABN: 65 144 615 896) and all payments made to us, shall be exclusively governed by these Terms of Delivery and Payment. Insofar as applicable provisions may be found to be missing therefrom the law of Australia applies. If any business terms of the Ordering Party’s are at variance with these General Terms of Delivery and Payment, we shall only be bound by such divergent terms if we have expressly recognised the same by letter or by telefax.

1.2 In taking delivery of the goods and/or service, the Ordering Party acknowledges the exclusive applicability of our Terms of Delivery and Payment.

2. OFFERS

2.1 Our offers may be changed or withdrawn by us at any time before acceptance by the Ordering Party, unless the offer makes express mention of an offer validity period. Documents pertaining to our offers – such as drawings, illustrations, samples and patterns, and dimensional, weight, performance and consumption data – contain or themselves constitute only approximate data and are not deemed to be specially agreed characteristics unless otherwise provided. We retain the right to effect modifications for engineering reasons.

2.2 We reserve the proprietary rights and copyright to all cost estimates, drawings and other documents. The Ordering Party must ensure that these are neither disclosed to any third party nor used for the purposes of any third party.  

3. ACCEPTANCE OF THE ORDER; SUPPLEMENTARY AGREEMENTS

Acceptance of an order, and any undertakings or supplementary agreements made by our employees, as well as amendments and alterations of any kind, shall not be binding upon us until we have issued written confirmation by letter, telefax or email.

4. PRICE AND PAYMENT CONDITIONS; OFFSETTING

4.1 Unless otherwise stated, prices are always the net price valid on the date of delivery and they shall apply Ex Works (EXW [Incoterms in the latest version]), but exclusive of packaging, insurance, loading at the factory and GST; packaging is not returnable.

4.2 Payments are to be made net cash, without any deduction and free of charges, within 30 days of the invoice date. It shall be for us to decide which claims or partial claims of the Ordering Party’s may be offset against such payments.

4.3 If any changes in order execution are necessitated by circumstances where risk is borne by the Ordering Party, then this latter shall bear all additional costs thereby incurred.

4.4 If the payment period is exceeded, we shall be entitled to charge default interest at a rate of ten percentage points above the applicable base rate announced by the Reserve Bank of Australia, plus the collection costs, such amounts to total at least 12% p.a. of the overall claim or such lesser amount determined by us. This is without prejudice to any further consequences of default in payment.

4.5 The Ordering Party must not withhold payments or offset these against claims we make.

4.6 Where the Ordering Party holds claims against ourselves, we are entitled to offset these against our own claims against the Ordering Party, at any time.

4.7 For services performed under contracts for work and materials (installation, repairs, maintenance and other such work), we shall charge the hourly rates and materials-prices applicable at the time of completion, plus our applicable surcharges for any overtime, night-time, Sunday and public-holiday working; travel and waiting times are counted as working hours. Travel expenses and daily and overnight allowances will be invoiced separately.

5. PERFORMANCE, SHIPPING AND DEFAULT

5.1 The delivery period commences with the mailing of the order confirmation note, while the performance period for installation, maintenance or repair work commences when the equipment is handed over. On no account, however, shall the delivery or performance period start to elapse sooner than 14 days after the time when the Ordering Party has furnished us with the documents (e.g. engineering drawings, plans etc), permits or approvals which it is responsible for procuring, or when it has made the agreed pre-payment. The delivery or performance deadline is deemed to have been met if we have notified the Ordering Party prior to such deadline of our readiness to deliver or perform. In cases where a special agreement obliges us to dispatch or deliver by a deadline, the delivery or performance deadline shall be deemed to have been met if the object of delivery or performance has left our factory prior to such deadline.

5.2 Delivery or performance periods are extended for the duration of any unforeseen impediments lying outside our control, such as but not limited to stoppages, major personnel outages, unlawful strikes, delays in supplies of essential raw materials or components or the like, as well as by circumstances where risk is borne by the Ordering Party, to the extent that these impediments and/or circumstances are of material relevance to the failure to meet the deadline. Impediments and/or circumstances of this nature also prevent a default arising for which we would otherwise be liable, for the duration of such impediments and no contractual remedies for which we would otherwise be liable will apply. Immediate notification is to be given by the Ordering Party of the beginning and end of such impediments. We are entitled to terminate the contract, in whole or in part, if such impediments should occur. In this case, to the extent permitted by law, we exclude all liability of any kind whatsoever except to the extent the Ordering Party proves intent and gross negligence on our part.

5.3 If agreed delivery or performance deadlines, or deadlines that have been extended in accordance with 5.2 above, are exceeded by more than four weeks, the Ordering Party shall be entitled to terminate the contract, having granted us at least 14 days’ extra time by notice given to us in a registered letter. In this case, to the extent permitted by law, we exclude all liability of any kind whatsoever except to the extent the Ordering Party proves gross negligence on our part.

5.4 If the Ordering Party incurs a loss from a delay for which we are liable, then it shall be entitled to compensation amounting to 0.5% per whole week - up to a maximum of 5% - of the value of that part of the delivery which cannot be used in time or for its intended purpose as a result of the delay. For other services, the compensation shall be 5% of the remuneration. In this case, we exclude all other liability of any kind whatsoever except to the extent the Ordering Party proves gross negligence on our part. In addition, we are not liable for any delays caused by our suppliers. This clause applies to the extent permitted by law.

5.5 In cases where we have undertaken to effect shipping, the mode and route of shipping shall be for us to decide. Goods are always shipped at the Ordering Party’s risk and expense. To the extent permitted by law, we exclude all liability of any kind whatsoever in relation to shipping except to the extent gross negligence is proven on our part. We shall only take out transport / breakage insurance by order and for the account of the Ordering Party.

5.6 We are entitled to effect part-deliveries.

5.7 Our compliance with the delivery period shall be contingent upon the Ordering Party having fulfilled its contractual obligations in all pending, still-to-becompleted business transactions.

5.8 If shipping is delayed due to circumstances where risk is borne by the Ordering Party, then this latter shall bear all resulting additional costs, such as those for storage at our factory, but with a minimum monthly charge of 0.5% of the invoice amount. In such a case we shall also be entitled to grant the Ordering Party a grace period of at most 14 days, and if this period should expire to no avail, we shall then be entitled, at our own discretion, either to make alternative arrangements regarding the article(s) to be delivered and to effect delivery to the Ordering Party within a suitably extended period of time, or to terminate the contract and claim damages for breach of contract. In this latter case, we are entitled, without having to furnish any particular proof, to require up to 10% of the remuneration for the intended delivery as indemnification. Where appropriately substantiated, we can also claim compensation for any damage over and above this amount.

5.9 Goods ordered on call, or for production with no shipping instructions, must be taken delivery of within three months. If this time limit elapses unused, then the goods will be treated as subject to a shipping delay due to circumstances where risk is borne by the Ordering Party, and 5.8 shall apply.

5.10 For services performed under contracts for work and materials (4.7), the Ordering Party is to provide us with the necessary equipment and auxiliary materials (e.g. winches, rails, electricity etc.), in good time and at no charge, even if installation is included in the price (4.1) or if a flatrate price has been agreed for this. Any works needing to be carried out by the Ordering Party preparatory to installation, e.g. building work, must be completed prior to the arrival of our installation technicians. Furthermore, the Ordering Party must take all safety precautions needed for the protection of persons and property. To the extent permitted by law, we shall not accept liability for the ancillary personnel, equipment and auxiliary materials which may be placed at our disposal unless gross negligence is proven on our part.

6. PASSAGE OF RISK

6.1 Unless otherwise stated, risk shall pass to the Ordering Party as soon as the articles to be delivered, or the articles on which we have performed maintenance, repair or other work, have left our factory. The same shall also apply to partdeliveries or in cases where we have undertaken to bear the shipping charges or to perform delivery, settingup, assembly, installation or other similar services. If the maintenance, repair or other work is carried out at the premises of the Ordering Party, then risk shall pass to this latter as soon as it has received notification that the work in question has been completed.

6.2 If there is any delay in dispatching or delivering the shipment for reasons for which we are not liable, the risk shall pass to the Ordering Party as soon as it has been notified that the consignment is ready for delivery.

7. RETENTION OF TITLE; RESCI

7.1 We shall retain title to the article(s) delivered until the following have been settled in full: our purchase-price claims; and all other claims that we have – on whatever legal grounds – against the Ordering Party. Our legal expenses incurred in connection with the enforcement of our title are to be borne by the Ordering Party.

7.2 The Ordering Party is only permitted to resell the article delivered – even if this has been joined to other items or subjected to processing – in the course of its company’s regular business operations. However, this permission is precluded if the resulting claims are assigned to third parties or are the subject of an assignment prohibition, or if the Ordering Party is insolvent or in default with the performance of its contractual obligations. No other manner of disposition whatever is permitted to the Ordering Party. In the event of distrainment, confiscation or other disposition by third parties, the Ordering Party is to notify us hereof immediately.

7.3 The Ordering Party assigns to us its claims and other rights from the re-sale, rental or leasing of the article delivered, even if this latter has been joined together with other items or subjected to processing; the Ordering Party shall make an entry to this effect in its books. If the article delivered is sold or placed into the hands of a third party for such party’s use together with other items (regardless of whether or not it has been joined to any such items or subjected to processing), then the receivables claim shall only be assigned up to the amount of the purchase price owed to ourselves. This is without prejudice to any further damages claims.

7.4 The Ordering Party is only entitled to collect the claims and to assert the other rights to the extent that it has met its payment obligations towards us and is not insolvent.

7.5 If the Ordering Party should act contrary to the terms of the contract – in particular by being in arrears with payment or with any other contractual obligation, and/or by being insolvent – we shall be entitled, at our own discretion, either to terminate the contract without granting any grace period or, while leaving the contract in force, to take back the article delivered or to forbid it to be used. We shall also be entitled to sell the taken-back article in the open market; after deduction of a handling fee of 10% of the proceeds thus realised (or such lesser amount determined by us), the remainder will be debited from the total of our outstanding claims against the Ordering Party. In the event of our terminating the contract, we shall charge the Ordering Party a usage fee of 5% of the original value of the article (or such lesser amount determined by us) or the actual diminution in its value if greater.

8. WARRANTY

8.1 Certain legislation, including the Australian Consumer Law, may imply guarantees, warranties or conditions or impose obligations upon ourselves which cannot be excluded, restricted or modified, or cannot be excluded restricted or modified except to a limited extent. These General Terms of Delivery and Payment must be read subject to these statutory provisions.  

8.2 We give no warranty for ordinary deviations in size, weight or quality (or as tolerated by ÖNORM, EN or DIN standards or other applicable standards), and also no warranty for information given regarding the suitability of the article(s) to be delivered for the purpose contemplated by the Ordering Party, or for any other particular purpose.

8.3 We warrant the correctness of our processing instructions, user/operating manuals and customer advisory service. We do not warrant compliance with statutory or other regulations when using the articles delivered, and the testing of these articles for the purpose envisaged, shall remain the sole responsibility of the Ordering Party. To the extent permitted by law, we shall only be liable for any instructions differing from our written processing instructions and user/operating manuals if we expressively previously confirmed these deviations to the Ordering Party in writing, either by letter, telefax or e-mail.

8.4 Articles or services supplied must be inspected by the Ordering Party immediately after delivery has been taken of them. Any defects must be reported to us during the warranty period and immediately upon being discovered, in a written notice sent by letter, telefax or e-mail quoting the number and date of the order confirmation note, of the delivery note or of the invoice, and the serial and commission numbers. If the Ordering Party omits to make this immediate notification, it may no longer assert any warranty claims or claims for compensatory damages on account either of the defect itself or of any misapprehension as to whether the delivery or service was free of defects. The notice must set out which delivered items or supplied services are affected by the defects, what the defects consist of in detail, and under what concomitant circumstances these defects occurred. Every single defect must be exactly described. Any costs which we incur as a result of unjustified notices or notices that are otherwise at variance with the conditions of use are to be refunded to us by the Ordering Party. The liability limitations in this clause apply to the extent permitted by law.

8.5 In the case of corrective and preventive maintenance work, our warranty shall be limited to the services actually rendered. We shall only warrant correct functioning of an installation, machine, software or the like whose components were not all supplied by ourselves if we provable have undertaken – despite the provision of certain components by the Ordering Party or by third parties – to manufacture the installation (or machine etc.) as a whole, and if the faulty functioning in question is not attributable to incorrect or incomplete information from the Ordering Party.

8.6 Unless otherwise agreed, the warranty period for all warranted articles or services shall be 24 months. From the beginning of the 13th month of this period, however, our warranty shall be limited to making available, free of charge, the items needed for remedying the defects; from this time onwards, any warranty claims going beyond the above shall not be permitted. This period of limitation also applies to the supply of items deemed to be immovable and to work on items which are, or are deemed to be, immovable. The warranty period shall start to elapse upon the passage of risk (6.). The Ordering Party must always prove that defects coming to light during the warranty period were already present at the time of the passage of risk.

8.7 In cases where we do give warranty, we shall – at our own discretion and within a reasonable period of at least 4 weeks’ duration – either exchange the defective article itself, or its defective components, for a defect-free article or defect free components, or remedy the defect(s), or grant the Ordering Party a reasonable reduction in price, or (unless the defect in question is a minor one) cancel the contract. The warranty period is not prolonged by the exchange of the item or of parts or components belonging to the item. If, however, the remainder of the warranty period – including that part of the period during which our warranty is limited to free provision of the requisite materials (8.5) – lasts for less than twelve months, then the warranty period for the exchanged items, parts or components shall be extended to twelve months. The items, parts or components thus exchanged shall become our property. We shall not refund the costs for any actual or attempted remedying of a defect by the Ordering Party or by any third party.

8.8 To the extent that is necessary and may reasonably be expected of the Ordering Party, the object of delivery or performance, or the defective part(s) thereof, are to be dispatched or shipped to us immediately at our request, at the Ordering Party’s risk and expense, failing which to the extent permitted by law any and all warranty obligation on our part shall become void.

8.9 The Ordering Party is not entitled to withhold payments on account of warranty claims or other counter-claims not recognised by ourselves.

8.10 Warranty claims from the Ordering Party are excluded in cases where the installation, user and operating manuals provided by ourselves, or to be requested from us by the Ordering Party, have not been observed, or where the user has not fully observed such instructions; if the installation work has not been performed properly and in accordance with the relevant Standards, and in particular if the installation work was not carried out by licensed contractors; if any corrective maintenance or other work has been performed on the object of delivery or performance without our consent; if it has been improperly operated or used, or operated despite its protective features being faulty, or taken out of the contract territory without our consent, or used contrary to our instructions or for purposes for which it is not intended; and, moreover, where defects are attributable to foreign object damage, chemical influences, overvoltage, the conduct of third parties or to force majeure; the same applies in respect of natural wear-and-tear.

8.11 Our warranty is also excluded in cases where we have been contracted to carry out repair-orders, to alter or modify used items, or to supply such items.

8.12 Finally all warranty claims shall be excluded if Contractee installs third-party components or replacement parts in our delivery items or services provided by us which have not been expressly recommended by us prior thereto.

8.13 In addition to the rights of Contractee in accordance with Point 8.6 regarding the delivery of inverters for photovoltaic systems the guarantee in accordance with the guarantee conditions of Fronius shall apply, available at https://www.fronius.com/en/photovoltaics/products/all-products/solutions/fronius-service-solutions/fronius-warranties/fronius-warranties

9. DAMAGES

9.1 We shall indemnify the Ordering Party for damage it suffers directly to the extent that the Ordering Party proves that we ourselves brought about this damage either knowingly and willfully or grossly negligently. If the Ordering Party proves that we have caused damage in an ordinarily negligent manner, to the extent permitted by law and subject to clause 9.4, our obligation to indemnify shall be limited to the direct damage actually incurred by the Ordering Party, and, moreover, to a maximum overall amount not exceeding the total order value. Furthermore, to the extent permitted by law, claims of this type may only be enforced if made by the Ordering Party within six months of the damage in question becoming known.

9.2 In the event that a claim is made by a third party, and we have produced and delivered in accordance with the drawings, designs, models or other documents provided by the Ordering Party, the Ordering Party shall indemnify and save us harmless for all loss suffered in connection with that claim.

9.3 To the extent permitted by law, our liability to pay damages for property damage, including all rights of recourse, is excluded. When using the installations, machines and other articles delivered by ourselves, the Ordering Party is obliged to strictly observe all safety regulations, technical rules, installation regulations, operating instructions and user manuals, and in particular all regulations applying to the electrical engineering field, and to allow only authorised skilled personnel to operate the equipment.

9.4 Certain legislation, including the Australian Consumer Law, may imply guarantees, warranties or conditions or impose obligations upon ourselves which cannot be excluded, restricted or modified, or cannot be excluded restricted or modified except to a limited extent. If such legislation applies, to the extent permitted by law, we limit our liability in respect of any claim under such legislation to:

in the case of goods, at our option: 

(i) the replacement of the goods or the supply of equivalent goods; 

(ii) the repair of the goods; 

(iii) the payment of the cost of replacing the goods or of acquiring equivalent goods; or 

(iv) the payment of the cost of having the goods repaired.

 

in the case of services, at our option: 

(i) the supplying of the services again; or 

(ii) the payment of the cost of having the services supplied again.

9.5 Any liability for damage caused by the installation or use of third-party components or replacement parts with our delivery items, which have not been verifiably and expressly recommended by us, shall be excluded.

10. CONSENT TO DATA PROTECTION

Client shall agree that Fronius International GmbH and its subsidiaries may collect, process and use personal data (such as name, address, email address), if applicable also by commissioning a service provider, for the purpose of sending information regarding products and services of any kind (e.g. by post, email, newsletter and more). A dissemination to externals in excess thereof shall not occur (excluded are legal or judicial obligations to provide information). The consent may be objected at any time in writing, in the newslet-ter there is also a link to unsubscribe.

11. FINAL PROVISIONS

Legal disputes arising out of the contract are to be governed by Australian law and the Courts of Victoria shall have non-exclusive jurisdiction. The UN Convention on Contracts for the International Sale of Goods, on the other hand, shall not be applicable.

12. SPECIAL PROVISIONS FOR SOFTWARE SUPPLIED TOGETHER WITH ORDERED ITEMS OR SOFTWARE SUPPLIED SEPARATELY

For software delivered together with other items or for software delivered separately (hereafter “software”) these Terms and Conditions of Delivery and Payment only apply insofar as these do not deviate from the following conditions or from conditions agreed upon separately with Contractee.  

12.1 SCOPE OF USE

12.1.1 All rights of intellectual property, such as copyright, trademark rights, design rights, patent rights, utility model rights and know-how, as well as in particular unprotected inventions, commercial experience, trade secrets and such like, independent from the time these were disclosed to Contractee, shall be reserved at any time by us or our licensors. Contractee shall have the right to use the software after payment of the agreed sum exclusively for his own purposes in accordance with the acquired number of licences. With the present contract only the authorization to use the software is acquired. Dissemination by Contractee shall be excluded in accordance with the copyright law. With a possible participation of Contractee in producing the software no rights other than the specified usage laid out in Section 12 are acquired. Contractee may only use the software simultaneously on one device, which one is his decision. Usage of the software shall constitute any long-term or even any temporary duplication (copying) of the software, whether in whole or also only in part, by saving, loading, running or displaying for the purpose of execution of the software and processing of the data contained therein by the hardware. He shall not be authorized to copy the user manual.

12.1.2 Contractee shall be permitted to make copies of the software for archival and data protection purposes on condition that there is no explicit prohibition in the software or any accompanying material (instruction manual, packaging, etc.) and that all copyright and proprietary notices are transferred unchanged in these copies. Retranslations of the programme code (decompilation) exceeding the legal provisions shall not be permitted.

12.1.3. If the software is equipped with technical copy protection, Contractee shall in the case of damage be supplied with a replacement copy after restitution of the data carrier.

12.2 FURTHER RIGHTS

In the event of availability of a new software version Contractee shall be entitled to exchange the supplied software package for a similar software package of the new version at our listed update price; the exchange implies the software package as a whole, as it was acquired by Contractee. With the exchange Contractee’s permission to use the exchanged software package shall expire. In such an event Contractee shall immediately and completely destroy all copies, partial copies and backup copies as well as altered or revised versions of the software and the copies, partial copies and backup copies made thereof.  

12.3 WARRANTY

12.3.1 Contractee shall note that it is not possible to develop software programmes in such a manner that these are free from defects for every application condition.

12.3.2 We shall warrant that the supplied software fulfils the agreed functions and has the expressly guaranteed properties. Requirement for any warranty is usage according to contract. A defect for which we are responsible shall only be deemed to exist if the software does not function according to the most recent version of the corresponding performance description/ documentation and if this is reproducible by Contractee. In order to carefully examine possible occurring defects Contractee shall be obliged to support us in the rectification of any defects.

12.3.3 We further shall warrant that the original software is duly recorded onto a tested data carrier. Excepted here from are previously installed software and third-party software products. 

12.3.4 Software defects shall be documented by the user and we shall be notified in writing with immediate effect; otherwise 8.3 shall apply. 

12.3.5 The warranty period shall always be twelve months; the period commences with the dispatch of the software package.

12.3.6 If the software package is not usable or defect (12.3.2), we shall exchange it primarily for a new one of the same title or for an adequate alternative solution. If this also proves to be unusable or defect and if we are not in a position to make it usable with adequate effort within an adequate time, but at least within a period of four weeks, Contractee may demand a price reduction or a change. Costs of defect rectification by Contractee or a third person shall not be compensated by us. 

12.3.7 In excess of this (12.3.6) we shall not provide warranty, in particular not in the case of the supplied software not meeting the special requirements of Contractee or user, and also not for altered or revised versions of the software (point 12.1.2), unless Contractee can prove that the defects are not connected to the alterations or revisions. Contractee himself is solely responsible for the selection, installation and usage of the software as well as for the results intended therewith.

12.3.8 In the event of unjustified assertion of defects in the software we shall be entitled to charge Contractee with any incurred costs according to valid cost rates.

12.3.9 A change of the end-user shall exclude any warranty claims.

12.4 COMPENSATION

12.4.1 All further claims of Contractee or third persons, in particular claims for compensation for damages of any kind, shall be excluded, unless the injured party can prove that the damage was caused by us either intentionally or due to gross negligence.

12.4.2 Otherwise 9 shall apply accordingly.
