Consultant was excellent
Consultant was excellent. Went through our bill and suggested the right battery to suit our needs. Came out and completed a thorough assessment of the site. My install date was 2 months after the consultation but I was contacted and kept in the loop, installing the app and receiving emails. I was contacted the week prior to installation by the consultant and was sent emails. I was even contacted after installation via the consultant. Very happy with the installation.
32Kw Sigenergy battery installation
Had a 32Kw battery installed by RenewCo Solar on 27th Oct 2025 and couldn't be more happy with the install. Installers were awesome, very professional and knowledgeable and answered the questions I had gleaned from various Facebook groups. Even the required stickers were placed on the back of the Distribution Board as requested. Once the install was completed, the battery was charging as the approval was already done. Received the link to install the My Sigen App on the phone and once completed the log in, the picture you can see shows todays power generation and Zero from the grid. Definitely recommend RenewCo Solar and contact Todd Williams if you are Sydney based and he will come out for an inspection prior to the quote.

RenewCo works done well to a high standard
Gave me a great price by around $2K compared to the next best. And receiving an extra battery module for free due to losing the State Govt rebate was a bonus. Sometimes a little slow on response but that was to be expected with the high demand just before solar battery rebates were kicking in. Good on the comms with WhatsApp originally and now moved onto their own App. All site visits turned up on time and got the work done pretty quick, although glad I went up on the roof a few times to observe the install as they were about to install panels over a very visibly cracked tile before I asked them to replace it first. A little slow on part of the works to move the Off Peak HWS over to the battery which was part of the quote, but I had to keep pushing for this and it did happen 6 weeks after the initial install. But overall everything got done and is working great. Solar panels are exceeding my expectations, and since swictching the HWS to battery I have NOT paid for electricity off the grid for a month now. Looking forward to see the summer output and now contemplating the switch to Amber.
Solar Panel - REC
Getting good output and seem to be a LOT more efficient than my previous panels from over 10 years ago. All black panels look good.
Solar Inverter - Sigenergy
Cant complain about anything as yet, all working well.
Battery - Sigenergy
Battery is performing well doing all general power plus the HWS. 32KW is a good size if there is two consecutive rainy days. Shouldn't have any corrosion issues as its installed in the back of the garage with bollards to protect from the cars. App is good and it really does seem quite accurate to what seems to be going on. There is a slight discrepance between what the app says has been fed back to the grid and what the meter/electricity provider say I have fed back - about 1% diff.

Friendly staff, smooth process from beginning to end
Im very happy with the service from presales through to the install. Install crew were onsite exactly as they said, no fuss install, left the area clean and tidy.

Backup and self consumption battery. Very happy!
Very professional job and battery integrates really well into our old system. Matt answered all my stupid questions while trying to work best solution for us. All admin handled seamlessly through Whatsapp. Very good value for money Sigen battery.
Good quality installation
Good quality installation - if probably a little on higher end of the scale price-wise. Support has been mostly great although very busy at the moment with all the battery installs
EV Charger - Zappi
App works really well - have had no troubles connecting. The only downside to this charger (and probably most) is that it hates direct sun on hot Sydney days. Throttles down to less than 4Kw. Worth getting a cover over the unit to shade it.
Excellent service and competitive pricing
Great experience from start to finish with RenewCo Solar. Highly knowledgable pre-sales that prepared a custom solution based on our needs, responsive communication and professional install.

Hi Alex,
Thank you for your kind words, we look forward to continuing to support you and can't wait to see how you get on with your new system!
Battery - Tesla
Too early to comment on overall battery life however initial monitoring is excellent through tesla app.
Accesible, Professional, Punctual
- Managing Director very accessible for questions during pre-purchase phase. - Queries answered promptly which was extremely important due to the purchase of a Sigen battery system which was largely untried in the Australian marketat the time of purchase (Nov. 2024). - Installers punctual, friendly and efficient. - Whatsapp group based service provides quick and targeted (and mostly) timely responses. - After sales service adequate.

Solar Panel - Jinko
Started off with an 8.3kw array in August 2023 and upgraded with another 5.3kw of south facing panels for a total of 13.6kw, consisting of 31 x Jinko 440w panels with the battery install. Working as promised with about 70% efficiency from the south dacing panels at 30 degrees pitch. This equates to a maximum production of approximately 10kwh during the summer solstice (21/12/2024) for approximately 5 hours on a cloudless day in Sydney.
Solar Inverter -
Perfect. I am no electrical engineer, but the inverter works seemlessly with a maximum 10kw output. We apparently had a blackout which I did not even notice until I looked at the app and saw the battery discharge rate, due to the 0sec switch over time. My switchboard was sadly in need of an overhaul, so the necessity of upgrading to 3-phase was carried out in conjunction with the installation.
Battery - Sigenergy
All I can say is forget Elon and Tesla, buy this. The main selling point to me was the modular design with 5kw and 8kw units avaialble at time of writing. It is rumoured that larger capacity battery modules will be available in Australia soon. When the ineveitable march toward 0 or even negative FIT arrives, I can just add additional capacity to store exceess production at minimal cost. The maximum battery capacity for the single controller and gateway is 25kw, so I could add another 8kw moule for a total of 24kw and virtually go off grid. As yet, I haven't changed to Amber or another time of use / AI provider as I have credit with my current provider and they paid me for my services during December :-) A family of 4 in a 2 storey fully electrical (no gas) using 1062kw in December, the system produced 2043kwh, with 974 used and 1069 exported. My rates were $0.2827 per kwh / $0.858 per day / $0.07 FIT. Email me on gangof5@bigpond.net.au if you require any more information on my Sigen installation.

Appeared when they said, worked hard, cleared up after and so far (2 weeks) all is good
