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.

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.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

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.

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.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Hugh Speirs · Apr 2026 Trustpilot

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.

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 (their Trustpilot reviews don't lie!). 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.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

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!

⚡ 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.

ℹ️

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.

Diagnostics

5-step SigenCloud reconnection guide

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).

1

Check the SigenStor gateway LED indicators

Find the SigenStor gateway — it is either built into the inverter or a separate module connected to it. Check the LED indicators:

LED indicators
Power LED: Should be solid when the gateway has power. If off, the gateway is not receiving power — check the physical connection to the inverter.
Network LED: Solid = connected to WiFi. Flashing = trying to connect (needs reconfiguring). Off = no WiFi module activity.
Cloud LED: Solid = uploading data to SigenCloud. Off or flashing = not communicating with the cloud server.

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.

2

Power cycle the SigenStor system

A full power cycle clears transient communication faults between the gateway, inverter, and SigenCloud:

1. Turn off the AC isolator for the SigenStor inverter.
2. If you have battery modules, turn off the battery isolator(s) as well.
3. Wait 60 seconds — this allows capacitors to discharge and all modules to fully shut down.
4. Turn the battery isolator(s) back on first, then the AC isolator.
5. Wait 5–10 minutes for the system to fully restart, re-establish BMS communication, and reconnect to 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.

3

Confirm your router broadcasts 2.4GHz WiFi

The SigenStor gateway only supports 2.4GHz WiFi. This is the single most common reason reconnection fails after a router change:

Separate bands: If your router broadcasts separate 2.4GHz and 5GHz networks, use the 2.4GHz network name when configuring the gateway.
Combined band: If your router uses one name for both bands, the gateway may connect to 5GHz and fail. Split the bands in your router admin or ensure 2.4GHz is available.
Mesh routers: Systems like Google Nest WiFi, Eero, or BT Whole Home may need band steering disabled for IoT devices. Check your mesh system documentation.
Quick test: If your phone can connect to the same WiFi from the room where the SigenStor is installed, signal strength is likely adequate for the gateway.
4

Reconfigure WiFi using the Sigenhome app

If the gateway still shows no network connection after power cycling, the stored WiFi credentials need updating:

1. Download the Sigenhome app (iOS or Android) and log in with your existing account.
2. Stand near the SigenStor inverter — you need to be within WiFi range of the gateway.
3. Navigate to Device Settings → WiFi Configuration in the app.
4. Connect your phone to the gateway broadcast network — it will appear as a network named with the gateway serial number. Your phone temporarily disconnects from your home WiFi.
5. Enter your 2.4GHz WiFi network name and password. Double-check the password — one wrong character will cause the connection to fail.
6. Tap "Configure" and wait 1–2 minutes. The network LED should change from flashing to solid, confirming a successful connection.

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.

5

Verify the connection in SigenCloud

After the gateway reconnects, wait 10 minutes for it to begin uploading data. Then check:

Gateway LEDs: Network and cloud LEDs should both be solid
SigenCloud dashboard: Should show live generation, battery SoC, and grid data with a current timestamp
Historical gap: Data from the offline period will be missing — this is normal and cannot be recovered
Still offline? Power cycle the entire system once more (AC and battery isolators). If still not connecting after a second attempt, the gateway hardware may have failed and need replacing. Book a diagnostic and we'll confirm.

Why Sigenergy monitoring goes offline — and why it matters

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.

FAQ

SigenCloud offline — common questions

SigenCloud relies on the SigenStor gateway maintaining a WiFi connection to your router. When you change broadband, replace your router, or update the WiFi password, the stored credentials no longer match and the gateway drops offline. The inverter and battery continue operating normally — only the monitoring link is broken.
The gateway has LEDs for power, network, and cloud status. Solid network LED means connected to WiFi. Flashing means trying to connect but failing — needs reconfiguration. If the power LED is off, the gateway is not receiving power from the inverter. If the network LED is solid but SigenCloud shows no data, check your account registration.
Use the Sigenhome app. Navigate to WiFi Configuration, connect your phone to the gateway broadcast network, and enter your new 2.4GHz WiFi credentials. The gateway only supports 2.4GHz — 5GHz will not work. After entering the new details, the gateway restarts and reconnects within one to two minutes.
Yes. We review your SigenCloud account status and guide you through reconfiguration in a remote session. Someone needs to be physically near the inverter during WiFi setup. If the gateway hardware has failed, we confirm remotely and advise on replacement. Book a remote diagnostic to get started.
Repeated disconnections usually indicate weak WiFi signal at the inverter location, an unstable 2.4GHz network, or band steering on a mesh router forcing the gateway onto 5GHz. Test by checking if your phone holds a stable WiFi connection from the same room. A WiFi extender or access point near the inverter resolves most intermittent disconnection issues.
