Solar Tech Support is an absolute lifesaver. My solar and battery system stopped working completely, but after one quick phone call, they fixed the problem straight away. The original provider, GivEnergy, has gone into administration, leaving me entirely without support from the original installers. It was a terrible situation on GivEnergy’s part, but thankfully, Solar Tech Support came to the rescue!
Thank you for your diligence. On this occasion the battery was able to be saved but they have given a route to hopefully arrange a repair from the manufacturer.
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
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.
Called back within a day and gave good advice.
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 SolarEdge faults we see come down to the optimisers. They talk to the inverter over the DC power line in a daisy chain, so one failed connector or optimiser can knock a whole run of panels offline, showing up as N/A in the monitoring portal or a P404 pairing fault in SolarEdge Go. Plenty of those P404s appear right after an automatic firmware update and clear with a 90-second soft reset.
The rest splits into a few camps: HD-Wave inverter failures (the SE3000H to SE6000H units built 2017 to 2020 have a known premature-failure history, covered by the 12-year warranty), systems sat at 0W from an isolation fault or a tripped isolator, and the safety end: a red light or an arc fault (P700/P701) that needs isolating, not resetting.
Each guide below works the same way. We start with what SolarEdge Go and the monitoring portal can tell us remotely, sort what can be sorted from there, and only book a visit when the fault is physical. The diagnostic is free, and warranty claims with SolarEdge are handled for you.
Each topic links through to an engineer-led step-by-step guide.
