1 Stop Solar

I WOULD ADVISE TO STAY AWAY FROM THESE PEOPLE BASED ON MY CURRENT EXPERIENCE I am giving a 1-star for now because there are a lot of ongoing issues and I am having great trouble contacting and getting help from the service team (Name Removed). We installed in Cambrian Hill VIC in March 2026. My experience until the time of the installation was… Read more

very good. The team was easy to contact. The rate was very good and they kept their word.

The installer was not the best. He wanted to leave the place in a mess. I had to take photos and threaten with a complaint to have him remove the junk that he was planning to leave around including the boxes, nails, wire, paper and polythene. The installer also wouldn't help me with the app and I could not see if the system was working well before he turned it off.

The system was approved by powercor.

However, the system is faulty. We have a FOXESS EQ4800 system. It is AC coupled. It behaves very erratically and has tripped the mains switch on quite a number of nights. The battery charges and discharges to the grid unnecessarily. Charging at 20 cents per KWh and discharging at 1 cent to the grid. Also does not seem to sense the requirements of the house in self use mode.

They seem to think that the CT - clamp must have been installed incorrectly. They have also escalated to FOXESS who are apparently not taking service calls due to their current focus being on rebates and new connections. I have this in writing from them!

It costs more to keep the battery on than off. So I have disconnected it manually for now until they are prepared to sort it out.

The service team is awful. I was lied to. [Name Removed] mentioned that they had looked at the usage two weeks ago on one of his first calls. I had previously given them my logins. I asked him when and they said earlier in the week. However, I had manually disconnected and turned off the battery for the previous entire 7 days. There was no way that he could have looked at that data. So I did accuse him of being 'not very truthful'. It was quite disappointing to start a conversation like that.

The latest issue is that I received an email on 21st april that they had not received the inverter serial number and that they had suspended the requested changes to the connection. I forwarded it to the service team. I also called up powercor today and enquired. The installer has simply not bothered to respond.

I am very disappointed with the 1 stop solar service team. I have had a good experience until the time of installation.

I understand that there can be teething issues and I am happy to work through them. Its difficult when they are dishonest. However, if these issues are solved, I will update this review and may change to a good star rating.

I HAVE AN UPDATE - The installer has sent the serial number of the Foxess through. However, now there is no export. I spoke to Powercor and apparently, the installer has erroneously nominated the AC coupled Foxess battery inverter for the emergency backstop. Therefore, Powercor has deregistered my Sungrow inverters from the backstop. Hence, my export is limited to zero! Now, I have to ask my shifty installer to deregister the foxess and register the sungrow. Going by their previous enthusiasm, it is going to take about three more months before I have export. The battery issue is still not sorted. No communication regarding a timeframe for the installer to return to connect the CT Clamps or FOXESS company input. I will keep this update ongoing as things happen. VERY DISAPPOINTED FOR NOW

29th June - I have another update. I had an email from 1Stop solar that they have corrected their error with the nomination of the inverter for the emergency backstop. I received an email from Powercor too. However, I still don't have export. There is no word from them about the installer or when he would return to fix the clamps. In the meantime, the battery is off. It has been 4 months since installation - still no usable battery. I WOULD ADVISE TO STAY AWAY FROM THESE PEOPLE BASED ON MY CURRENT EXPERIENCE

The team is very supportive and very quick to respond. The whole system including the battery took 2 weeks since signing the contract to be installed. Highly recommend

1 stop Solar Adam and team it was truly amazing journey from start to finish giving me a great quote meticulously tailored to my Solar needs and the trades people that came to put the Solar in were prompt polite clean and quick putting the Solar Panels on and the batteries in and was up running the same day. They also downloaded the app which I… Read more

find amazing. I’m able now to see how much power I’m generating and how much I’m using. This is one of the best decision I’ve made, it’s always difficult to know who to go with when you’re paying out so much money but I did my homework which took quite awhile,I might add but I chose 1 Stop Solar as they stood out from the crowd really feel lucky that I’d chosen them they’ve also contacted me since I’ve had it in to see how it’s all running, I haven’t had any problems at all. And would recommend them to anybody. The other thing I liked about them is they explain everything to you I needed to know how it all worked, their expertise and their knowledge was incredible, and most of all could explain it in a way where I could understand how it all worked which was very important to me.

Communication was great with a very responsive team that always returned calls if missed the first time. The installation process was carried out by very professional and polite contractors.

This has been a shocking time as they are very pushy pushy pushy to try and get me to sign up to solar saying that I would come in with the time of the new deadlines they rang me three weeks ago and said though will deliver the solar panels that I'd have to pay full price on drop off all the money you shouldn't have to do that should be able to… Read more

give them half and then half at in completion would not recommend these guys say something to get you signed up pay a $300 deposit and not come through with the deal and tell me they can't do it it is very bloody confusing dealing with these people as they aren't English speaking very hard to understand please please do not use these people at all they are very big liars and untruth they tell

SCAM!!! deal with caution. Signed contract to get battery installed, paid deposit and they cancelled last minute citing that price change. Have not returned my deposit and no communication.

Worst Experience Ever. There always seems a problem and they make you feel like your the issue not them. They like to quickly take a deposit and communication is almost nothing after that. When you do get onto them they are full of excuses and speak rudely to you making you feel like your the problem. On completion of the project they also have… Read more

tried to extort more money out of me saying "double story installation" Yes i live in a double story but all the work was done on the ground floor and no-one went onto the first floor. The installation was conducted 2 metres form the meter box on the ground floor

Expect to hurry up and wait and for an installation to never happen

I cancelled the battery installation after the company demanded full payment ($6,200) prior to installation. A representative named Max had initially offered a 50/50 payment arrangement — half before and half after installation — but then threatened to forcibly enter my property and repossess the battery if I did not comply. Following this threat, I ended the call and cancelled the installation.

I accepted 1 Stop Solar’s offer in December and paid my deposit on 6 January. I spoke with them multiple times and was repeatedly assured the battery would be installed during my stay at the property. Based on those assurances, I travelled 3,000 km return, costing me significant time, fuel, and lost opportunities. After I arrived, they delayed… Read more

again, advised they couldn’t complete the installation, and then refused to reimburse any of my travel costs. To make matters worse, they also mentioned possible price increases, even though the delays were entirely on their side. This was extremely unprofessional. Repeated assurances, broken promises, poor communication, and zero accountability. I would strongly recommend avoiding this company.

Not a reliable installer, convinced to lock in quotation and now called back to say they cannot install

Very helpful and friendly all the way through installers were great. Would recommend.

I had a 42Kw solar battery installed from One Stop Solar this week, and the whole process from getting a quote to getting the battery installed was run very smoothly, they were very good at communicating and letting me know everything, they came in and installed it all in one day, and helped me with app installation and made sure everything was… Read more

running smoothly before leaving, I highly recommend 1 stop Solar for their excellent costumer service and work efficiency.

Battery and panels, great price,great install ,im very happy with the performance of the system !Brinda and Alan helped with quiestions etc ,they made it a simple proccess .

Do not use this company under any circumstances. They take your money, install half a system and then never come back. They will lie for months making up false excuses and deliver nothing. Scam. I will be taking them to fair trading

Great communication and service, I would recommend for their great job.

Joe and Brett were very good with their follow up and very helpful in answering any queries good customer service .

Tassie battery installation (Fox ESS 42kwh/10kw inverter $8350 with one back up circuit). I'd avoid them if there is ANY other option. Full of hollow promises if they can be bothered replying. Clearly had no intention of installing my battery. Ordered in 20August2025, Grid connection application applied for in November, no response provided… Read more

to network provider so application cancelled by grid provider in Jan, said it was sorted and would be installed by end of Jan2026. Grid provider confirmed no further application had been received late Jan26 so I cancelled (I suspect thats what they were hoping for all along). Bleeped.
