Absolutely brilliant service. Our GivEnergy battery stopped working for no obvious reason. The manufacturers have gone in administration so no aftercare is available. Our installer could not diagnose the problem and gave up. We were at our wits end. A web search came up with Solar Tech Support. In truth, the reviews almost seemed to good to be true. But Ron diagnosed the problem within the hour and fixed it remotely the same day. He explained everything clearly and thoroughly and has offered solutions to other issues we had too. I honestly cannot recommend Ron highly enough. An absolute godsend in the mess that GivEnergy have left behind in their demise. Thank you again for all your help!

Excellent knowledgeable company which sorted out my Givenergy issues that no one else could sort! Initial remote diagnosis into what unit(s) where faulty which enabled me to confidently source and buy a replacement at a good price and on so doing Solar Tech then got my system up and running remotely within an hour or two. A1 service!
When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.
Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
What actually goes wrong with Solis inverters
Most Solis faults we deal with are settings or grid problems, not failed hardware. The two we see again and again are grid overvoltage trips on S6 and RHI models, where the inverter disconnects at midday because local grid voltage has pushed past the 253V ceiling the network has to stay within, and generating but not exporting, which is nearly always a zero export limit in SolisCloud, a reversed CT clamp or the wrong G98/G99 grid code. In both cases the inverter is doing exactly what it has been told to do.
The CT clamp turns up in both problems. Fitted backwards, it gives the inverter the wrong picture of what is flowing to and from the grid, so Volt-Watt response misfires and export gets blocked when it should not be. It is one of the first things we check on a Solis system.
Because everything is configured through SolisCloud, most of this can be diagnosed and put right remotely. The diagnostic is free and you only pay if we fix it.

Each topic links through to an engineer-led step-by-step guide.
Inverter grid overvoltage fault — causes & fix
Your Solis inverter shows "Grid Over Voltage" and stops exporting during midday solar peaks.

Solis generating fine but not exporting to the grid? Usually a setting: a zero export limit, a reversed CT clamp, or the wrong G98/G99 code.
