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.

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.
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.
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
My 90-year-old father-in-law had a solar system installed nearly three years ago that never worked properly and kept tripping out. Neither the original installer nor GivEnergy could resolve the issues, and we were even pushed towards replacing the system entirely when GivEnergy went bust. I contacted Ron at Solar Tech Support via WhatsApp, and within a few hours he had diagnosed multiple faults — including incorrect wiring that posed a potential fire risk. He carried out a home visit in Nottingham for £295 (including parts), fixed everything, completed firmware updates, and ensured the system was fully operational. Since then, it has worked perfectly. Ron was knowledgeable, responsive, and took the time to explain everything clearly. Highly recommended — excellent value and complete peace of mind.
I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration. So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.
What actually goes wrong with Victron kit
Victron kit rarely fails as hardware. What fails is the conversation between the parts. The most common job we see is a MultiPlus that has stopped charging, and it is nearly always a settings or communication problem: wrong charge voltages in VEConfigure, an AC input limit set too low, or the battery BMS pulling the charge current limit to zero through DVCC.
Communication faults are the other big group. VE.Bus errors take the whole inverter-charger down and usually trace back to a poor RJ-45 cable or a firmware mismatch between units. CAN bus dropouts between a Pylontech, BYD or Dyness battery and the Cerbo GX leave the system safe but idle. Add seasonal MPPT Error 33 trips from cold-weather string voltage, overload shutdowns on off-grid systems, generator auto-start that never fires, and VRM dropping offline through weak WiFi at the GX device.
The good news is Victron exposes nearly everything in VRM and VictronConnect, so we read the alarm history and the live DVCC limits before anyone touches a screwdriver. Pick the fault below that matches yours, or get in touch and we will track it down.
7 common problems & faults we cover
Each topic links through to an engineer-led step-by-step guide.
battery BMS disconnect — DVCC fix & repair
Your Victron system has stopped charging or discharging the battery — the BMS has disconnected or triggered a protection. Free remote diagnostic.
generator auto-start fault — diagnose & fix
Your Victron system should start the generator automatically when the battery runs low — but it isn't. Free remote diagnostic — no fix, no…
inverter overload shutdown — causes & fix
Your Victron MultiPlus or Quattro has shut down on overload — the load connected to the AC output exceeded what the inverter can deliver.
MPPT error codes — PV overvoltage fix
Your Victron SmartSolar or BlueSolar MPPT controller is showing an error code — most likely Error 33 (PV overvoltage) or Error 38 (PV input…
MultiPlus Not Charging — Charge Parameter
Your Victron MultiPlus or MultiPlus-II runs but won't charge the battery — state of charge is stuck or falling. Causes from settings to DC…
VE.Bus error codes — RJ-45 cable fix
Your Victron system is showing a VE.Bus error — the MultiPlus or Quattro has stopped and the system is in a fault state. Free remote diagnostic.
VRM Portal offline — Cerbo GX WiFi fix
Your Victron VRM portal is showing the system offline — you can't monitor battery state of charge, inverter output, or solar yield remotely.
