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.
Ronald was great to help me sort out my giv energy inverter issue since company has gone bankrupt in april 26.
My Givenergy battery stopped working nearly a month ago. After unsuccessfully reaching out to my installer, who looks like he's also busted, I found Solar Tech Support on a Google search. They fixed my issue in a couple of hours. Any frustrated Givenergy customers, I highly recommend these guys.
My GivEnergy solar and battery system is failing intermittently, GivEnergy is in administration and so is my installer, so it was a relief to get Ron’s expert advice.
When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.
Our SolarEdge PV system with LG batteries had its first hiccup after 8 years of hard work. The Inverter failed. Fortunately I found Solar-Tech-Support who diagnosed the problem very quickly, ordered a replacement unit and fitted it shortly after we received the unit from SolarEdge. Very thorough and professional approach. Thank you, a solid 5 star recommendation.
Most Powerwall faults we see are settings and metering problems, not a dead battery. The single most common is a CT clamp fitted backwards: the Gateway misreads solar or house load, so the battery won't charge from solar or sits full and exports when it should be running the house. Wrong operating mode and tariff windows that don't match your Octopus times cause most of the rest.
The Gateway is behind the other two themes. If it drops offline after a router change (Gateway 2 is 2.4GHz only, and port 1883 needs to be open) you lose app monitoring while the battery quietly carries on. In a power cut, circuits wired outside the Gateway or a contactor that fails to switch can leave a fully charged Powerwall doing nothing, and a backup reserve set too low leaves little in the tank when the grid drops.
Each guide below works through the checks in order, starting with what you can see in the Tesla app. If you get stuck, the remote diagnostic is free, and we're independent of Tesla and your installer.
Each topic links through to an engineer-led step-by-step guide.
