STS were incredibly responsive and helpful In diagnosing an issue with my GivEnergy inverter. Although distance meant it was impractical for me to use them to fully solve the issue, I’m grateful for the help and detail they provided. Don is a real professional gent and a hero in my eyes.
I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!
I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.
What a fantastic service. Had my fault diagnosed within minutes and actually managed to resolve the issue remotely within a few minutes more. This guy is like a “Solar Batman” helping consumers fix their problems using his extensive industry knowledge and expertise. Outstanding service. Thank you so much.
Excellent response to diagnose a problem on our SolarEdge installation. Kept us informed at every step. Diagnosis quickly completed and solution implemented.
Our 3 year old GivEnergy batteries froze. They were showing 0% on the app, but they were fully charged. Some how Ron took over our inverter and remotely cured the problem. We live in King’s Lynn, he is in Leeds I believe. Very grateful.
Safety Warning
Do not open your inverter or interfere with DC cabling. Solar panels produce live DC voltage whenever exposed to light. Always use your DC isolator switch and contact a qualified solar engineer for hands-on fault diagnosis.
Important: SigenCloud going offline does not affect your solar generation or battery operation. The SigenStor continues working normally without cloud connectivity. What you lose is visibility — you cannot monitor performance, check battery state of charge, or receive fault alerts until the connection is restored.
Most SigenCloud offline issues are caused by a WiFi connection loss at the gateway. Work through these steps — the majority are resolved by step 2 (power cycle) or step 4 (WiFi reconfiguration).
Find the SigenStor gateway — it is either built into the inverter or a separate module connected to it. Check the LED indicators:
If the network LED is solid green but SigenCloud shows no data, check your SigenCloud account — the issue may be with account registration rather than connectivity.
A full power cycle clears transient communication faults between the gateway, inverter, and SigenCloud:
Check SigenCloud after 10 minutes. If data is now updating with a current timestamp, the issue was a transient fault and no further action is needed.
The SigenStor gateway only supports 2.4GHz WiFi. This is the single most common reason reconnection fails after a router change:
If the gateway still shows no network connection after power cycling, the stored WiFi credentials need updating:
If the gateway broadcast network does not appear in your phone's WiFi list, try power cycling the system again. Some gateways only broadcast their configuration network for a limited time after startup.
After the gateway reconnects, wait 10 minutes for it to begin uploading data. Then check:
Sigenergy SigenStor systems use a built-in or plug-in gateway to send performance data to SigenCloud. The gateway stores your WiFi credentials and maintains a persistent connection to your router. When you change broadband providers, get a new router, or update your WiFi password, the stored credentials no longer match and the gateway drops offline. This is the single most common cause of SigenCloud monitoring going dark — and it happens to every brand that uses WiFi connectivity for monitoring.
While the gateway is offline, the SigenStor inverter and battery modules continue operating normally. Solar generation continues, the battery charges and discharges according to its programmed schedule, and EPS backup remains functional. What you lose is visibility: you cannot check battery state of charge, verify solar output, track self-consumption, or receive fault alerts. For homeowners on the Smart Export Guarantee, monitoring data also supports export payment verification.
Sigenergy is a relatively new brand in the UK market, and their monitoring platform is still maturing. If the standard reconfiguration steps do not resolve the issue, the gateway hardware itself may have failed — STS can confirm this remotely by reviewing the SigenCloud account status and LED behaviour you describe.
