My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.

I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Our 3 year old GivEnergy batteries froze. They were showing 0% on the app, but they were fully charged. Some how Ron took over our inverter and remotely cured the problem. We live in King’s Lynn, he is in Leeds I believe. Very grateful.

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.
