When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.
Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate
Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.
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.
Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.
What actually goes wrong with Fronius inverters
Fronius inverters tell you what is wrong with a numbered state code, and the first digit tells you how serious it is. Codes in the 100s are grid trips that clear on their own, 300s are normal low-light messages, 400s are hardware or software faults, and 500s are notifications. The two faults that come up most on UK Primo and Symo units are the isolation fault (state 475 and 502), nearly always water getting into an MC4 connector or the rooftop DC isolator, and grid overvoltage (state 102), where the voltage at your property climbs past the 253 volt limit and the inverter has to disconnect.
State 102 is not an inverter fault; it is your local network, and the lasting fix usually comes from the DNO. An isolation fault is the opposite: a genuine safety shutdown that needs a proper inspection, not repeated restarts. And if Solar.web shows you offline, the system is almost certainly still generating; the Datamanager card has just lost its WiFi link.
We start every job by reading your Solar.web event log remotely to work out which of these you are actually dealing with. The diagnostic is free. No fix, no fee.
4 common problems & faults we cover
Each topic links through to an engineer-led step-by-step guide.
Grid Overvoltage — Frequency Fault & State 102
Your Fronius inverter is disconnecting because the grid voltage at your property exceeds 253 volts — the upper limit set by UK grid code G98.
Isolation Fault — State 475 & 502 Earth Fault
Your Fronius inverter has shut down because it detected a drop in DC insulation resistance — a leakage path to earth somewhere in the solar…
Solar.web Offline — Not Updating or Connecting
Your Fronius Solar.web portal shows the system as offline or the monitoring data has stopped updating. Free remote diagnostic — no fix, no…
State Code Alarm — Inverter Error Codes
Your Fronius inverter is displaying a numbered state code — a status message telling you something abnormal has been detected. Not all codes…
