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.

Great service. Got our Givenergy battery back online remotely when others said it needed an onsite visit. Ron resolved the issue within about an hour of my email. Brilliant service.
Absolutely amazing service. Ive had a couple of issues with my Givenergy system and couldn't manage to get in touch with Givenergy after they went bust. So I was searching on Google and came across Rons number. I sent Ron a WhatsApp message and got a prompt reply and he resolved the problem I had with my system. I can't recommend Ron enough its not often you get such a good service in this day and age. If you are experiencing issues with your solar system Ron is the man to contact.
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.
Ronald was great to help me sort out my giv energy inverter issue since company has gone bankrupt in april 26.
Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.
Common Solis problems we diagnose
Every fault below has a proven diagnostic path. Click through for the specific page or book a diagnostic if you're unsure.
Inverter powered but not generating. Check the SolisCloud dashboard for error codes. Common causes: DC isolator tripped, string fault, or grid disconnection fault. Solis inverters give a clear fault description in the monitoring.
See diagnostic guide →The inverter has disconnected from the grid because AC voltage exceeded G98/G99 limits. Common in streets with multiple solar systems. The inverter reconnects automatically, but if trips are frequent, export limiting or DNO notification may be required.
See diagnostic guide →SolisCloud shows generation well below expectations for your location and panel count. Could be partial string failure, soiled panels, or an inverter operating at reduced capacity. We compare expected vs actual output to isolate the fault.
See diagnostic guide →SolisCloud (formerly Ginlong Portal) shows no data. The WiFi datalogger has lost connectivity. Usually caused by router change, password update, or logger hardware failure. The inverter continues operating normally when monitoring is dark.
See diagnostic guide →Solis dataloggers require 2.4GHz WiFi. After a router upgrade or change, the logger needs reconfiguring. We walk through the SolisCloud logger setup process remotely.
See setup guide →System generating but not exporting to the grid. Most commonly caused by the export limit setting in the inverter being set to zero, a failed CT clamp, or a G98 export configuration error.
See diagnostic guide →Solis inverters use a CT clamp to measure grid import/export. If installed backwards, the inverter misreads grid flow — leading to incorrect export limiting, wrong energy accounting, and battery dispatch errors on hybrid models.
See diagnostic guide →Solis inverter completely dead — no display, no fans, no response. Could be a failed AC or DC isolator, a wiring fault at the inverter input, or a hardware failure. Safety note: do not open the inverter.
See diagnostic guide →Solis fault code index
Solis inverters display error codes on the LED panel and in SolisCloud. Common categories: grid fault codes (voltage, frequency), isolation fault codes, DC bus faults, and temperature warnings. Share your exact code when you book — we identify the root cause as part of the remote diagnostic.

About Solis systems — what you need to know
Solis (made by Ginlong Technologies) produces affordable, reliable string inverters that are well-regarded in the UK residential solar market. The product range includes the S5 and S6 series single-phase inverters and the RHI series hybrid inverters with battery integration. Monitoring is provided by SolisCloud (formerly the Ginlong Monitoring Portal) via a WiFi datalogger. Solis inverters are known for their simple, no-fuss operation — but the monitoring system can be tricky to reconfigure after router changes.
The most common Solis issues we handle: Solis grid voltage fault, SolisCloud offline, Solis not exporting, Solis underperforming, and Solis installer gone bust. Grid voltage faults are disproportionately common with Solis systems in solar-dense streets — this is a grid infrastructure issue, not a fault with the inverter itself. STS provides independent Solis support across the UK — not affiliated with Ginlong Technologies.
STS supports all major inverter and battery brands — not just Solis. If you have a mixed-brand system or are comparing options, visit the brand hub.
