How to restart a GivEnergy battery

A battery-only restart clears BMS communication faults, resets stuck SoC readings, and resolves LED fault conditions — without a full system power-down. Covers Gen 2, Gen 3, and AIO systems.
  • Hybrid Gen 2, Gen 3 and AIO covered
  • No tools or isolator switches needed
  • Settings are not affected by a battery restart
Battery fault not clearing after restart?

If a fault code or battery issue reappears within minutes of a restart, the underlying cause needs diagnosing. We can read your event log and live data remotely — usually faster than GivEnergy support queues.

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.

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!

When to restart
When

Battery restart vs full system restart

A battery-only restart is quicker and less disruptive — no isolators to touch, no interruption to solar generation. Use it first. Only escalate to a full system restart if the battery-only restart doesn't resolve the issue.

Try battery restart first for

Flashing red or amber battery LED
Battery SoC stuck at 0% or an incorrect value
CAN communication fault on the inverter display
Battery not charging or discharging despite correct settings
Battery appeared to turn itself off unexpectedly

Escalate to full system restart if

Battery restart resolves the fault but it reappears within minutes
Inverter display is frozen or blank
Portal is offline and WiFi reconnect hasn't helped
GivEnergy support has directed you to do a full restart
Battery won't respond to the on/off button at all
Hybrid — Gen 2 & Gen 3
Hybrid

Battery restart — GivEnergy Hybrid (Gen 2 and Gen 3)

On Hybrid systems the battery unit is separate from the inverter. The on/off button is on the front or side of the battery enclosure.

Battery restart steps

1
Press and hold the battery on/off button to shut it down

Locate the on/off button on the GivEnergy battery unit — usually on the front panel or right-hand side. Press and hold for 3–5 seconds until you hear a beep and all LED indicators go out. The battery is now off. Do not proceed until all lights have extinguished.

2
Wait 30 seconds

Allow 30 seconds for the BMS capacitors to discharge fully. This ensures a clean restart rather than just a brief power interruption. The inverter will report battery communication loss during this period — this is expected.

3
Press and hold to power the battery back on

Press and hold the same button until you hear a beep and the LEDs illuminate. On Gen 2 and Gen 3 batteries, the LEDs will cycle through a startup sequence before settling on the current SoC indication. This takes up to 60 seconds.

4
Wait 2–3 minutes then check the portal

The battery reconnects to the inverter over the CAN bus. Allow 2–3 minutes, then check MyGivEnergy — the battery SoC should update and any previous communication fault should clear. If the fault code reappears within 5 minutes, move to a full system restart.

Gen 3 note: Some Gen 3 battery units have a slightly longer startup sequence — LEDs may cycle through colours for up to 90 seconds before settling. This is normal. Do not press the button again during startup.
AIO System
AIO

Battery restart — GivEnergy AIO (All-in-One)

On the AIO, the battery is integrated inside the combined unit. The shutdown button is the large blue GivEnergy button on the front; the startup button is the smaller button to the right of the DC cover.

AIO battery restart steps

1
Press and hold the blue GivEnergy button to shut down

The large blue button is on the front face of the AIO unit. Press and hold for approximately 5 seconds until you hear audible clicks and the unit goes quiet. The front indicator light will go out. The AIO is now in standby.

2
Wait 30–60 seconds

Allow at least 30 seconds — 60 seconds is preferable for a complete BMS reset. The AIO may make occasional quiet sounds as internal relays settle; this is normal.

3
Press the small startup button to restart

The startup button is the small button to the right of the DC cover (not the large blue button). Press and hold until the front indicator light appears. The AIO will begin its startup sequence — do not press any buttons during this process.

4
Allow 5 minutes for full restart

The AIO takes longer than a standalone battery to complete its startup — the inverter and BMS initialise together. Allow up to 5 minutes before checking MyGivEnergy. The portal will show offline during startup; this is expected and resolves automatically.

Troubleshooting
Troubleshooting

Battery won't turn back on — what to check

If the battery doesn't respond to the on/off button or doesn't come back on after restart, work through these checks before calling GivEnergy support.

1
Check the battery DC MCB (Hybrid systems)

Open the battery flap and check the position of the DC MCB breaker. If it has tripped to the DOWN position during the restart attempt, push it firmly back UP. A tripped MCB prevents the battery from starting — this is the most common reason a battery appears unresponsive after a restart attempt. Close the flap and retry the startup button.

2
Check the AC isolator is ON

If the AC isolator on the wall has been switched off (circle symbol = off), the battery cannot power on as it has no AC reference from the inverter. Confirm the AC isolator is in the line (ON) position — pointing straight up. On AIO systems, also check the AIO isolator on the unit itself.

3
Check for a separate wall-mounted DC breaker (older Gen 2 systems)

Some older GivEnergy Gen 2 installations have a separate DC breaker mounted on the wall rather than inside the battery flap. If you have one of these, check it is in the ON position. It looks similar to an AC isolator and is usually located near the battery unit.

4
Check the CAN communication cable

The CAN cable is a small connector (usually RJ45 or a proprietary plug) that runs between the inverter and the battery. If this has come loose — which can happen during property moves or when working near the units — the battery may start but immediately report a communication fault. Check both ends of the cable are firmly seated.

!
If none of the above helps — contact support

If the battery still does not power on after checking all of the above, the issue is likely a hardware fault — failed BMS board, tripped internal protection, or a battery cell fault. This requires a remote diagnostic or an engineer visit. Do not attempt to open the battery enclosure — this voids the warranty and is unsafe.

After restart
After

What to check after the battery restarts

LEDsBattery LED should settle to a solid green (standby or fully charged) or solid blue (charging). A flashing pattern that persists after 2 minutes indicates the fault has not cleared.
PortalOpen MyGivEnergy and check the battery SoC is reading a realistic value — it should match the approximate level before the restart. If it shows 0% or 100% and the system was at a different level, the BMS re-sync is still in progress.
Fault logGo to Settings → Fault Log in MyGivEnergy and confirm the previous fault code has cleared. A restart event should appear with no new fault codes following it.
ChargingConfirm the battery is charging from solar (if solar is generating) or from the grid (if in the AC Charge window). If the battery shows as full but no power is flowing, check the charge schedule and mode settings.
TimingAllow at least 10 minutes before concluding the restart has or hasn't worked. BMS re-synchronisation and portal updates are not instantaneous.
FAQ

Frequently asked questions

Press and hold the on/off button on the battery unit until you hear a beep and the LEDs go out (3–5 seconds). Wait 30 seconds, then press and hold again until the LEDs come back on. On an AIO, use the blue GivEnergy button to shut down, wait 30–60 seconds, then press the small button to the right of the DC cover to restart. Allow 2–5 minutes for the battery to reconnect with the inverter.
No. Charge schedules, system mode, discharge cut-off, and all other settings are stored in the inverter's non-volatile memory — not the battery. Restarting the battery does not affect these settings. After restart, the battery reconnects to the inverter and resumes using the existing configuration.
Check the battery DC MCB inside the battery flap — it may have tripped to the down (off) position. Push it back up and retry. Also confirm the AC isolator is in the ON (line) position. On older Gen 2 systems, check for a separate wall-mounted DC breaker. If all isolators are on and the battery still won't respond, it likely has a hardware fault requiring a diagnostic or engineer visit.
The battery itself restarts in under 2 minutes. Allow 5–10 minutes for the battery to re-establish communication with the inverter and for MyGivEnergy to update with current status. During this period the portal may show the system offline or the battery SoC may display incorrectly — this is normal and resolves as the BMS re-synchronises with the inverter.
