Absolutely wonderful support. I have a GivEnergy system that was installed in 2022, and a firmware update was flagged in the app, so I proceeded to update the software .... and immediately regretted it, as my inverter came up with an error, and was not working at all! With no GivEnergy support available, and my installer saying there was nothing he could do, I googled help, and found Ron. What a stroke of good luck! Submitted an on line enquiry late morning, and received phone call just after 5 pm, and later that evening Ron was able to supply me with old firmware no longer available on the GivEnergy web site. I was then able to update the firmware using a GivEnergy youtube video as reference, and hey presto the system was back up and running. One further slight adjustment by Ron and we are back normal. What a relief. I have no hesitation in recommending Solar Tech Support if you have a problem. Great service! And if you are a GivEnergy system owner, whatever you do, DO NOT UPDATE FIRMWARE!

Ronald tried to help solve a fault with communications between battery and inverter. Whilst in the end a hardware fault was diagnosed and not possible to fix remotely his attempt to fix and guide me through steps to fault find were appreciated. He was available at a time convenient to my availability. Great service for anyone requiring independant tech support for their solar or battery system.
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.
Sts does a extremely great job. Thank you.
Ron is one of those rare finds - an engineer's engineer. He insightfully and accurately diagnosed the problems with our GivEnergy system, very quickly, which helped get us back on track. We will be using him again!

What actually goes wrong with Sofar kit
Two faults account for most of the Sofar calls we get, and both are covered in detail below. The first is grid disconnection. The inverter drops off the grid with a G-OV, G-UV, G-OF or G-UF code in the SolarMan event log. In the UK the usual culprit is local grid voltage climbing past 253V at midday when local solar systems all export at once. The inverter is doing its job, not failing. A G-ISO code is the odd one out: that points to a DC insulation fault and needs on-site testing.
The second is specific to the ME3000SP, the AC-coupled battery unit installed between 2016 and 2021. It stores energy fine, then provides nothing in a power cut. Usually that's a missing neutral-earth bond on the EPS circuit, EPS mode never enabled at commissioning, or no changeover relay fitted at all.
Both start the same way: a free remote diagnostic. We read your SolarMan logs and settings, tell you what's actually wrong, and whether anything on-site is needed. No fix, no fee.
