Goedemans v Green Vision Group Pty Ltd (Civil Claims) [2025] VCAT 533
lights and other appliances. Ms Stewart said she was very clear about the need and purpose due to the lengthy blackout that occurred in the Dandenong Ranges during the severe storms in June 2021 and the fact that they live on a rural property that endures many blackouts. She said she explained to Mr Devenish that without power they cannot run the water pump and that they have no mains water and they are solely reliant on their water tanks for water.
Hybrid 9.53/2/5 (2.5kwh/ 2.25kwh usable) and the quantity of batteries to be supplied is "5". Ms Stewart said also included in the description of things to be suppled was "Black out protection". The quoted cost was $25,200 after deduction of STCs and solar PV rebate. The quote was signed by Mr Goedemans and Ms Stewart on 11 April 2021. She said the quote does not itemise the cost of the five batteries, but the cost of the batteries was itemised within the contract to be $14,900.00 and GVS does not dispute this price.
('WM') on behalf of SVG on 19 November 2021. A quote from WM dated 4 November 2021 directed to Daniel Carydias, Green Vision was provided to the Tribunal totalling $6,171.00 including GST.
with the battery manufacturer Sonnen and with the electrician installers, WM whereby she gave notice to each of them that the battery is not working, and they are without power. Ms Stewart said it was very stressful because each time there was a black out, they had no power or water which was impacting them financially because food perished, and they had to start using the generator again to gain power.
Please see the below report that I have compiled from feedback from my Field Service Coordinator and the service technician that we contracted to attend your home and investigate the issue you have raised. During the service visit on 14th found that the sonnen protect had been modified. The internal 10A breaker was replaced with a 25A Breaker. It was reported that this 10A breaker was tripping, sonnen assumes that the breaker changed to avoid continual tripping.
The issue that this has caused is that in a power outage our system can provide a max output of 2500W which is 10A through the sonnen protect.
The service technician found that on the Sonnen protect. It appears there are too many loads connected. It was reported that there are three water pumps, The kitchen circuit and some lights connected. The pumps traditionally have very high startup current rates, this means that one pump can trip the backup circuit as the start-up current is greater than the 2500W for too long during start-up causing the tripping
as kitchen circuits can include items like kettles and dishwashers. This only adds to the capacity wired into the project, meaning that in total, the loads wired into your system exceed the capacity.
As discussed, the sonnen 9.53 system you have at your home is a battery storage system. It will store energy from your solar panels to be used when required. The conversations that you had with the service technician, and I indicate that the requirements for your home currently exceed the system's capacity. Systems need to be designed with the owner's requirements taken into consideration; therefore, we recommend verifying what is exactly connected and reduced to loads from the project and/or have the design of system verified to see if your requirements are suitable for the 9.53's output.
We received a job sheet on the 29 October 2021 with site photos, which we assumed were from a site visit that they had performed. At no stage did green vision request us to carry out a site visit or involved in the selection of the products sold to you to fit your specific requirements.
The only note on the jobs sheet was that the site had two phases, there was no mention of the water pump. After sending quote for install to green vision I noted on photos that there was a generator changeover switch. Sent updated quote to green vision on 4 November 2021 to move the changeover switch into house switchboard to make install compliant in regard to solar. The first we knew of water pumps and that it was required to be on backup circuit was when we were wiring switchboard backup circuits on 9 November 2021. Backup usually consists of lighting, Wi-Fi, fridges and freezers so it was a surprise when you said this was the main reason for backup. We wired and tested water pump on back up several times during commissioning and at the time worked.. we tested system multiple times as the system that was sold is not really fit for the type of load and should not have been the system that was sold to you from green vision in our opinion.
We all agree your PV system and battery are working and operational; however, the issue lies within the battery operation during a blackout (which you have advised is unfortunately fairly common in your area).
The backup issue is due to your existing water pump exceeding the batteries backup limitations. When the pump starts up when you are "off-grid" it requires more power than is available causing the battery to trip and shut off leaving you without power. we previously agreed that a solution would be to replace the water pump with one that requires less power on startup, staying within the backup circuits limitations to ensure proper operation during blackouts. We offered to cover the cost of electrical and plumbing work with you supplying the new water pump however you declined this arrangement.
$14,900.00 on the grounds that the batteries were never fit for the purpose and the issue cannot be resolved other than by GVS offering to replace the water pump.
accordance with Mr Goldemans' and Ms Stewart's requirements after three months of discussion regarding their requirements which included nine alterations, and the applicants signed the contract on 4 November 2021. That Mr Goedemans and Ms Stewart did not seek to withdraw or cancel the contract before installation was carried out. That the system was correctly installed by WM on 19 November 2021 who are qualified electricians and that their work was inspected and certified with a certificate of compliance by a third-party inspector on 2 December 2021; and that GVS never received any complaints about the system at the time of installation. That GVS were first notified that the system was tripping on 29 January 2022 and arranged
for WM to attend and investigate the problem. An invoice from WM was provided to the Tribunal.
with a battery back-up to provide power for the water pumps, lights and appliances in the event of a black out. He agreed she was given the three options, and she chose the Sonnen battery. However, he said he advised Ms Stewart that the Sonnen batteries capacity was for 10 amperages back up and that Ms Stewart said the pumps only have 2.5 amperage capacity. Mr Devenish said ultimately the applicants signed the contract which provided for installation of a battery with capacity of 10 amperages and that is what they received and accepted, and the system functioned as it should within its capacity, that is it is only not working to power the pumps in the event of a black out.
A disclosed purpose is a particular purpose (whether or not that purpose is a purpose for which the goods are commonly supplied) for which goods are being acquired by the consumer and that:
(a) the consumer makes known, expressly or by implication, to:
(i) the supplier; or
(ii) a person by whom any prior negotiations or arrangements in relation to the acquisition of the goods were conducted or made.
(a) the goods would not have been acquired by a reasonable consumer fully acquainted with the nature and extent of the failure; or
(b) The goods are substantially unfit for a purpose for which goods of the same kind are commonly supplied and they cannot easily and within a reasonable time be remedied to make them fit for such a purpose; or
(c) the goods are unfit for a disclosed purpose that was made known to the supplier of the goods or by a person by whom any prior negotiations or arrangements in relation to the acquisition of the goods were conducted or made; and cannot easily and within a reasonable time be remedied to make them fit for such a purpose; or
(d) the goods are not of acceptable quality because they are unsafe.
consumer would suffer such loss or damage as a result of the failure: 259(4).
(a) I found Ms Stewart to be a reliable witness who gave cogent and clear evidence regarding her conversations with Mr Devenish prior to reaching agreement for the supply and installation of the battery. I am satisfied based on her evidence that she made it clear to Mr Devenish during the phone discussions before signing the contract the purpose of the purchase of the system included the operation of the water pump in the event of a power blackout. This was not disputed by Mr Devenish.
(b) I accept Ms Stewart's evidence that she did not advise Mr Devenish of any details regarding the pumps, including the power amperage of the pumps. This is because her evidence is consistent with her evidence that she knew nothing about solar or battery systems or water pumps or
amperage at the time and she was relying on Mr Devenish's advice,
skills and experience and or expertise.
(c) Making the purpose known to Mr Devenish orally by telephone satisfies the meaning of disclosure of a purpose contained in section 55(2) of the ACL because it includes conveying the purpose verbally.
(d) The quote and contract also include reference to the words "black out protection" and Mr Carydias and Mr Devenish do not dispute that Mr Goedemans and Ms Stewart required the battery to provide back up in the event of a black out.
(e) It is clear Mr Goedemans and Ms Stewart relied on the skill and judgment of the suppliers as they had no knowledge of solar or battery systems at the time, including technical matters such as the required amperage that is needed for them to have the battery power the water pumps in the event of a black out.
(f) It is clear that the battery system was never fit for purpose because it did not have capacity to provide power back up for the water pumps. This is confirmed by the manufacturer Sonnen, the electrician installer, WM and Mr Carydias himself in their email correspondence provided by Ms Stewart and it was conceded by Mr Carydias whilst giving evidence.
(g) I do not accept that GVS's offer of settlement to mitigate Mr
Goedemans' and Ms Stewart's loss by replacing their five water pumps with one water pump was a reasonable offer because the one replacement pump would require Mr Goedemans and Ms Stewart to accept an inferior system regarding their capacity for the supply of water for their purposes on their premises.
(h) I do not accept the contention made by GVS that they have provided a battery that was fit for purpose because Mr Goedemans and Ms Stewart accepted their written offer contained in the quote for a battery with a specific capacity. This argument ignores the fact that Mr Goedemans and Ms Stewart made it clear the purposes of having battery backup was to provide power to run the specific power sources, namely and most importantly the five water pumps in the event of a black out. Given their lack of expertise and clear reliance on GVS's skill and judgment it was GVS's responsibility to ask any relevant questions
regarding Mr Goedemans and Ms Stewart's needs and to address them
as part of what advice is given regarding a suitable battery back-up system that will power the water pumps in the event of a black out.
(i) I do not accept GVS's argument that the electricians WM that installed the system are responsible to Ms Stewart and Mr Goedemans for any failure of the system to work because they were responsible for the design and installation of a system that was fit for purpose. Mr Carydias conceded that the contract for installation was between GVS and the WM not between Mr Goedemans and Ms Stewart and WM; and therefore it is clear that Mr Goedemans and Ms Stewart had no contract with WM regarding design or installation requirements and were reliant on GVS to ensure that the system was correctly designed and installed by the electrician so that it was fit for the their purpose.
(j) In conclusion, I find that the battery was not fit for purpose to provide the necessary power for the water pump in the event of a power black out, and that Mr Carydias and Mr Devenish conceded that this was a priority or essential purpose of the system; and that Ms Stewart relied on Mr Devenish's advice regarding the correct battery that would be fit for purpose.
(k) Having found that GVS is in breach of section 55 of the ACL I now address the question whether Mr Goedemans and Ms Stewart are entitled to the remedy they are seeking.
(l) I find that I am satisfied Mr Goedemans and Ms Stewart are entitled to a refund of the cost of the batteries installed. They required a system that would work to provide the functions they requested in the event of a black out and the system failed to work, I am satisfied this constitutes a major failure.
(m) This is because pursuant to sections 2 and 260(a) of the ACL the battery would not have been acquired by a reasonable consumer fully acquainted with the nature and extent of the failure. A reasonable consumer who needs a battery to supply power for the pumps for the water tanks, flushing toilets, drinking water, showers and heating and power for the fridge, lights and other appliances during a black out would expect the battery to work during those times.
(n) Further, the battery is substantially unfit for the purpose for which goods of the same kind are commonly supplied and the goods are unfit for a disclosed purpose that was made known to the supplier's sales manager and representative Mr Devenish and that cannot easily within a reasonable time be remedied to make them fit for such a purpose other than by replacing the battery with a battery that can provide the power required.
(o) I am satisfied that the rejection period had not ended because I am satisfied they rejected the goods and requested a refund within a
reasonable period of time. I am satisfied on the basis of Ms Stewart's evidence that they tried unsuccessfully to negotiate with GVS, the manufacturer Sonnen and the electrician WM to resolve the problem but after many attempts to remedy the problem unsuccessfully, and receiving advice the problem could not be fixed without replacing the battery or reducing the number of water pumps they rejected the goods
within a reasonable time after becoming aware that the fault could not be fixed and made their application to VCAT.
(p) Accordingly, I am satisfied Mr Goedemans and Ms Stewart are entitled to reject the goods and seek a refund of the amount paid for the battery in the amount of $14,900.00.
(q) Mr Carydias and Mr Devenish asserted that Mr Goedemans and Ms Stewart did not provide any evidence regarding the cost of replacing the battery with a battery that is fit for purpose. However, the applicants are not claiming the cost of a suitable replacement, they are claiming a refund of the costs of the battery because the battery is not fit for purpose. I accept their evidence that the battery will cost approximately
$15,000.00 not including installation costs.
(r) The battery has never worked to power the water pumps during blackouts since installation and therefore Mr Goedemans and Ms Stewart have not had the use of the battery for its primary purpose for the three years since it has been installed. They are entitled to a full refund in order to put them in the position they would have been had the breach of the guarantee under section 55 not occurred.
