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 Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
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
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.
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.
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!

3 checks before anything else
These three checks resolve the majority of apparent hardware faults without any tools or specialist knowledge. Do them first.
Log into givenergy.cloud → My Inverter → Remote Control → Battery. Look at the Pause Battery setting. If it shows Paused, the battery is deliberately halted — it will not charge or discharge regardless of schedule, mode, or any other settings. This setting is the most overlooked cause of apparent hardware faults. Set it to Not paused if incorrectly set.
Physically inspect every isolator switch in the system. On GivEnergy systems, handle pointing UP means ON. A horizontal or downward-pointing handle means the circuit is open. An accidental knock or a deliberate service switch-off that wasn't reversed can leave an isolator in the OFF position and take down the whole system.
Look at the LED indicator on the GivEnergy inverter. A solid green LED indicates normal operation. Any other colour or a flashing pattern indicates a fault condition — note the exact LED behaviour and check the GivEnergy fault code guide for the meaning before proceeding further.
Checking GivEnergy isolator switch positions
GivEnergy systems have multiple isolator switches. All must be in the correct position for the system to operate. The rule is simple: handle UP = ON.
AC isolator (mains connection)
The AC isolator controls the mains electricity supply to the inverter. It is typically located near the consumer unit or inverter mounting position. Handle pointing UP = ON (closed). If this is OFF, the inverter has no mains supply and will not operate.
DC isolator (solar panel connection)
The DC isolator isolates the solar panel strings from the inverter. On most GivEnergy installations it is located near the inverter. If the DC isolator is OFF, the inverter cannot receive solar power. Handle UP = ON.
Battery isolator
The battery isolator is located on or near the battery module. If this is in the OFF position, the inverter loses communication with the battery entirely — you may see a CAN communication fault or similar error. Confirm the handle is pointing UP (ON).
Reading GivEnergy inverter LED status
The LED on the GivEnergy inverter gives a quick indication of system state. A solid green is the target — any other pattern warrants investigation.
| LED Colour / Pattern | Meaning | Action |
|---|---|---|
| Solid green | Normal operating state | No action needed |
| Flashing green | Starting up or communicating | Wait — allow 2 minutes to stabilise |
| Solid amber / orange | Warning condition | Check portal event log for warning code |
| Solid or flashing red | Abnormal/fault condition | Check fault code — see GivEnergy fault codes |
| No LED / off | No power — inverter not energised | Check AC isolator position |
LED behaviour can vary slightly between GivEnergy inverter generations. For Gen 4 models, refer to the specific LED guide in the GivEnergy knowledge base.
Battery temperature and the 0°C charge lockout
GivEnergy batteries have built-in temperature protection that can prevent charging in cold conditions. This is often mistaken for a hardware fault.
The 0°C charging threshold
GivEnergy lithium batteries will refuse to accept a charge current if the battery cell temperature drops below approximately 0°C. This is a Battery Management System (BMS) protection measure that prevents lithium plating — a form of cell damage caused by charging at very low temperatures. It is not a fault; it is expected protective behaviour.
The battery will automatically resume charging once the temperature rises above the threshold. If you are in a cold snap and the battery is in an unheated garage or outbuilding, this lockout may persist for several hours.
How to check the battery temperature
Log into givenergy.cloud → My Inverter → Event Log
Look for any temperature-related events — BMS temperature protection events will appear here when the lockout activates.
Some portal versions show live battery temperature in the monitoring dashboard — check the battery details panel.
Resetting the inverter settings to default
If the system is behaving erratically or displaying unexpected errors after configuration changes, resetting the inverter to factory default settings can clear corrupted configurations and restore normal operation.
How to reset settings via the portal
Log into givenergy.cloud and navigate to My Inverter
Go to Settings (usually in the left menu or main dashboard)
Look for an option labeled Reset settings to default or Factory reset
Click the reset button and confirm. The inverter will reboot with factory settings.
When to use factory reset
Reset the inverter settings if:
GivEnergy firmware update location and conditions
Regular firmware updates improve system stability and performance. Updates are performed via the portal and take approximately 15 minutes. The system must meet specific conditions before attempting an update.
Where to find firmware updates
Firmware updates are available in the GivEnergy portal:
Check this page regularly to see if a new firmware version is available for your inverter model.
Pre-update system conditions
Do NOT attempt a firmware update unless all of the following conditions are met:
The battery percentage must be showing in the portal. If SOC is not displayed, there may be a communication issue that should be resolved first.
The battery must show active charge/discharge current during the update. A standby battery may lose communication mid-update.
The battery module must show a steady green LED. Any other colour or flashing pattern indicates a fault that should be resolved first.
The inverter LED must be green, and the portal must show no active faults or alarms. All error conditions should be cleared before updating.
During the firmware update
Do not power off the system during the update. The inverter may restart and reinitialise several times — this is normal. The update process takes approximately 10–15 minutes to complete.
Once the update finishes, the inverter will restart automatically and return to normal operation. The portal will confirm the new firmware version once the update is complete.
How to safely restart a GivEnergy system
A controlled restart can clear transient faults and restore normal operation. The sequence must be followed in exact order to avoid creating new fault conditions on startup.
Follow this shutdown and startup sequence. Do not skip steps or change the order.
Shutdown sequence
Log into givenergy.cloud → My Inverter → Remote Control → Battery and set to Paused. This prevents the battery from trying to charge or discharge while you are switching isolators.
Turn the AC isolator handle to the OFF position (horizontal or down). This disconnects the mains supply from the inverter.
Turn the DC isolator to OFF. This disconnects the solar panels from the inverter.
Turn the battery isolator to OFF. If you have multiple battery modules, turn off each one.
Allow 2 full minutes for all capacitors in the inverter to discharge completely before restarting.
Startup sequence (reverse order)
Turn the battery isolator handle to UP (ON). If multiple batteries, turn all on.
Turn the DC isolator to the UP (ON) position.
Turn the AC isolator to the UP (ON) position. The inverter will begin its startup sequence — allow 2–5 minutes to fully initialise.
Once the inverter has started and the LED is green, go back to givenergy.cloud → My Inverter → Remote Control → Battery and set to Not paused.
If the LED is still not green after a full restart, if the system shows a persistent fault code you can't identify, if a battery module is not communicating (CAN fault), or if there are signs of physical damage — stop and contact us. Repeated restarts on a faulted system can cause further damage. We can review portal data and event logs remotely before recommending a site visit.
