GivEnergy Full Restart Procedure — Correct Shutdown and Startup Sequence

Restarting a GivEnergy system in the wrong order can cause BMS faults, communication errors, or an incomplete startup. This guide covers the correct shutdown and restart sequence for both GivEnergy Hybrid and AIO systems — the procedure used by engineers when clearing transient faults, communication errors, and post-firmware glitches.
  • Hybrid and AIO procedures both covered
  • Correct shutdown order prevents BMS faults
  • What to check after restart
Fault code still showing after restart?

If a fault code reappears within minutes of a correct restart, the underlying cause is persistent and requires a diagnostic review. We can check your event log and identify the root cause remotely — usually faster than waiting for GivEnergy support.

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!

When to restart
When

When a full restart is appropriate — and when it isn't

Restart is appropriate for

Frozen or blank inverter display that doesn't resolve after 5 minutes
Portal shows system offline after a brief power cut or grid disturbance
CAN communication fault after a firmware update
Battery showing 0% SoC despite being fully charged before shutdown
Inverter stuck in a mode it shouldn't be in (e.g. Bypass mode after a power cut)
GivEnergy support has advised a restart as a first step

Do not restart if

A firmware update is in progress — wait for it to complete (the display may appear stuck for up to 30 minutes)
You smell burning or see arcing — isolate at the consumer unit and call 999
The battery enclosure or inverter is visibly damaged
The system is showing a BATTERY_ERROR with over-temperature — let it cool for 2+ hours first
Safety: Do not open any inverter or battery enclosure. The AC isolator and battery side button are safe to operate — they are external controls. Everything behind a panel cover is live electrical equipment.
Hybrid system restart
Hybrid

GivEnergy Hybrid restart — inverter and battery as separate units

GivEnergy Hybrid systems have a separate wall-mounted inverter and battery unit connected by a CAN cable and DC MCB. The order of shutdown matters — turning the inverter off before the battery can cause BMS protection events.

Shutdown sequence — battery first, always

1
Turn off the battery using its on/off button

Press and hold the on/off button on the GivEnergy battery unit until you hear a beep and all LED indicators go out. This shuts the battery down gracefully before any DC isolation happens. Do not proceed until the LEDs are fully extinguished.

2
Open the battery flap and push the DC MCB down (OFF)

Open the battery's access flap to reveal the DC MCB breaker. Push it DOWN to the OFF position (some older systems have a separate wall-mounted MCB instead). Close the flap cover. This isolates DC current between the battery and inverter.

3
Turn the inverter AC isolator to the circle symbol (OFF)

The AC isolator is a rotary switch mounted on the wall below or beside the inverter. Rotate it to the circle symbol (OFF position). This disconnects grid supply and solar from the inverter. The inverter display will go blank.

4
Turn off the PV isolator (if fitted)

If your installation includes a separate PV array isolator switch, turn it off now. Wait at least 60 seconds before restarting to allow internal capacitors to discharge fully.

Gen 2 & Gen 3 Hybrid only: These models have a physical toggle switch on the inverter body itself. After the PV isolator step, set this toggle to the OFF position as well before waiting.

Restart sequence — inverter isolator first

1
Turn the inverter AC isolator to the line symbol (ON)

Rotate the AC isolator from the circle (OFF) to the line (ON) position — the line symbol points straight up. This restores AC power to the inverter first, which is the correct startup sequence.

2
Push the battery DC MCB up (ON) and close the cover

Open the battery flap and push the DC MCB UP to the ON position. Close the flap. This re-establishes the DC link between battery and inverter and allows the BMS communication to initialise.

3
Turn the battery on — press and hold until the lights come on

Press and hold the battery's on/off button until you hear a beep and the LED indicators illuminate. The battery will run a self-test sequence — LEDs may flash before settling. Wait for a stable pattern before checking the portal.

Gen 2 & Gen 3 Hybrid only: After turning the battery on, also move the inverter's physical toggle switch back to the ON position before waiting.
4
Wait 5–10 minutes for full reconnection

Allow the inverter to complete its startup sequence and reconnect to the cloud portal. The portal may show the system as offline briefly after restart — this is normal. Check the display and app after 10 minutes to confirm the system is back online and the battery SoC is reading correctly.

AIO restart
AIO

GivEnergy AIO restart — combined inverter and battery unit

The GivEnergy All-in-One (AIO) integrates inverter and battery in a single wall-mounted unit. The AIO has a DC MCB inside its DC cover as well as a blue button on the battery itself — both must be used in the correct order.

AIO shutdown sequence

1
Hold the blue GivEnergy battery button ~5 seconds

Press and hold the blue GivEnergy button on the unit until you hear clicks and the battery turns off. This shuts down the battery first.

2
Open the DC cover — push DC MCB down (OFF)

Open the DC cover panel on the AIO unit and push the DC MCB breaker DOWN to the OFF position. Close and tighten the cover. Wait 60 seconds.

3
Rotate the AC isolator to the circle symbol (OFF)

Rotate the AC isolator switch to the circle (OFF) position. The AIO is now fully powered down.

AIO restart sequence

1
Push the DC MCB up (ON) — close the DC cover

Open the DC cover, push the DC MCB UP to the ON position, then close the cover fully. This restores internal DC power before turning the unit on.

2
Press and hold the small button right of the DC cover

Hold the small button to the right of the DC cover until the front indicator light appears. This powers on the AIO unit.

3
Rotate the AC isolator to the line symbol (ON)

Rotate the AC isolator to the line (ON) position — pointing straight up. Wait 5–10 minutes for the system to come fully back online and reconnect to the portal.

After restart
After restart

What to check after a full restart

1
Confirm portal shows system online within 10 minutes

Open givenergy.cloud and check the system status. After a restart the portal may show offline for 3–7 minutes while the inverter reconnects to the cloud. If still offline after 15 minutes, check the WiFi connection is working — see our WiFi setup guide.

2
Check battery SoC is reading correctly

Battery SoC may briefly show 0% or N/A immediately after startup while the BMS recalibrates. Within 5 minutes it should show the correct current state of charge. If it continues to show 0% or N/A after 15 minutes, check the event log for CAN communication fault codes.

3
Check the event log for new fault codes

Go to givenergy.cloud → My Inverter → Event Log. Look for any fault codes that appear after the restart event. A clean restart shows only "System start" or similar. If the fault code that prompted the restart reappears within minutes, the restart has not resolved the underlying cause — a diagnostic review is needed.

4
Verify your settings haven't reset

Check Settings → Timed Charge/Discharge windows, system mode, and reserve SoC. If a firmware update ran during or after the restart, these settings may have been reset to defaults. Re-enter your schedule if needed — see our charge schedule guide.

FAQ

GivEnergy restart questions

For a GivEnergy Hybrid system: turn off the AC isolator on the wall, turn off the battery using the side button (hold until LEDs go out), move the DC MCB between battery and inverter to OFF. Wait 60 seconds. Restart in reverse: DC MCB to ON, then battery button ON (wait for stable LEDs), then AC isolator ON. For an AIO unit: turn off the AC isolator, press and hold the power button until the unit shuts down, wait 60 seconds, turn the AC isolator back on.
A controlled restart does not normally reset settings — charge schedules, system mode, and reserve SoC survive a power cycle. However, if a firmware update runs automatically after restart, it can reset settings to defaults. After any restart that follows a firmware update, check your settings in the portal and re-enter them if they have changed.
Yes — turning off the AC isolator disconnects the solar from the grid connection, so it is safe to work around. For simplicity, evening or early morning restarts are easier since solar is not producing. The restart takes 5–10 minutes and solar generation resumes automatically when the inverter completes its startup sequence.
It depends on the fault. Transient faults — caused by power interruptions, grid disturbances, or software glitches — often clear after a restart. Persistent hardware faults (damaged CAN cable, failed BMS board, inverter fault) will reappear within minutes. If a fault code reappears after a correct restart, the restart has not resolved the underlying cause — a diagnostic review of the event log is needed to identify the root cause.
