Sunboost generally receives positive feedback for its professional installation teams and efficient customer support, though a segment of customers reports significant issues with post-sales service and unexpected costs. While many users praise the punctuality and cleanliness of the installers, recurring complaints highlight lengthy delays in resolving technical faults and aggressive sales tactics regarding "on-the-day" price increases.
Pros
Cons
Verdict
Sunboost is a reliable choice for consumers seeking competitive pricing and professional installation, provided the site is straightforward and the quote is thoroughly vetted. However, potential customers should be prepared for possible "on-the-day" cost variations and may face significant delays if the system requires warranty repairs or complex post-sales troubleshooting.

At the end of June, we noticed that our battery was not charging during the daytime and thought there was an issue with our solar system. We contacted the Sunboost helpdesk, and Mr. Barry from the customer care team responded promptly. Barry carefully analysed the issue, explained the available options, and helped us resolve the problem… Read more
efficiently. We are very happy with the outcome and appreciate his professionalism and excellent customer service.
A big thank you to Mr. Barry and the entire Sunboost team for your prompt support. Highly recommended!
Hello As I put comments re Carson from Sunboost I am happy but something is bugging me that I was charged $800 for black out protection and battery installer agreed that took only 5 minutes to do that job. Thanks ANIL Rostrevor
Barry from Sunboost was very helpful in helping install my new 30 kW battery system. Any small issues that I might’ve had, they’ll quickly sort out by Barry and his team giving me full confidence with Sunboost. This is the second unit that SunBoost has installed for me. I’m quite happy with their work, the reliability, and their timelines.

After blackout our system often gets confused and readings are out eg house showing on app that it’s consuming a bunch more kw than it actually is so this time when I rang the problem was fixed fairly quickly by them doing some tweaks remotely. We also had had confusing over steps to shut down our system because our installer had done some… Read more
upgrades and added extra switches, we had emailed him but no response but after I sent pics to sunboost they numbered them and clearly gave us the order for safe shutdown. The man we dealt with was highly efficient however we have also been waiting for a response update on a costing to add an ev charger and costing for system maintenance for over two months by another worker who was actually the sales man that we dealt with a year ago that installed our second list of panels and battery system. He was good for that bent over backwards however a two month wait after talking with them and still no feedback as to costing we won’t be getting servicing or an ev charger addition through sunboost as it seems like it’s a bother for them. We were told we can go somewhere else so we have. We have mixed feelings regarding sunboost after sales support as well as sales honestly shop around and do your homework. Make sure your getting the right system and inverter for your planned system size and installer puts them in according to the manufacturers regulations as to not void warranty, they can all do better if ya ask me! Sungrow 10 kw hybrid inverter, 19.6 sungrow battery stack and two lots of panels all installed by sungrow rep at different times

Extremely happy with Sunboost for our Solar House Battery. Very competitive price. Installed within 1 week of purchase. We were very specific about how our Battery was to operate and it took a few phone calls to have it working to best benefit our lifestyle. Nothing was too much trouble for Barry to handle!

I had a problem with my inverter one phone call and it was fixed within an hour. Michael was very polite and understanding. Had lots of patience as I am not very tech savvy. After sales service has always been brilliant. Thank you solarboost. Peter
Negative reviews
This is my second system install from Sunboost. It took eight months from application to installation. This was an unacceptable wait time in my opinion. There were long times between updates, and many excuses. I almost cancelled. The system seems to be working well and the installers seem to be on the ball. It was all done in approx 4 hours. The 2 stars is simply for the wait time
Avoid this mob like the plague. 3 days to fit 8 panels, an inverter and battery, and they still haven't finished. They literally turn up for a couple of hours per day then disappear. Absolutely no communication. It took Arise Solar a few hours to fit a system 4 times bigger. There are better companies out there.

Big name but corrupt as hell, the installation person took extra for some component and I had no choice. Then I had some issue with the same thing, and I hired local electrician and I got to know it's way cheaper what I paid to this guys, and I called Julien to ask but all I got was "I'll get back to you" with some proper detail which obviously I never got.
