We decided to treat ourselves to an upgrade to our existing solar system, and after a little searching, it became evident that Ron and his team provide the service and support we required. Decommissioning and recommissioning our new SunSynk inverter and a wall-mounted Fogstar battery (which is of substantial size and weight compared to the original) was completed swiftly and competently. The installation was perfectly executed, and all upgraded paperwork for the increased battery export capacity was handled by Ron. I have no hesitation in recommending this team of support technicians to you.

Great experience with STS great communication from Ron, very helpful and knowledgable. Installed me a second Givenergy battery to help take the strain off my original 9.5 that needs refurb due to a weak cell. They secured me an 8.2 arranged install. Levi arrived the whole install was done within 1.5 hours - great tidy job. Worked with me to alter my setup to allow easy removal of my 9.5 when i can get it away for refurb - very happy with their service and its reassuring to know there is a company out there that can help look after my givenergy system
Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution
Had a problem with my GivEnergy battery which had decided to charge and discharge to a very limited extent. From AI, felt that the problem was probably a calibration issue on the Battery Management System, but which I could not fix myself. So contacted Solar Tech Support, and Ron was brilliant in being able to identify, confirm and fix the issue remotely and very speedily. Thoroughly recommend this outfit
I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.
Very happy with the support I got from Ron at Solar Tech Support with my GivEnergy battery problem. The battery having operated perfectly for 3 years suddenly stopped discharging. He sorted it out in minutes.
