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.

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.

BATTERY_ERROR with over-temperature — let it cool for 2+ hours firstGivEnergy 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
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.
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.
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.
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.
Restart sequence — inverter isolator first
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.
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.
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.
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.
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
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.
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.
Rotate the AC isolator switch to the circle (OFF) position. The AIO is now fully powered down.
AIO restart sequence
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.
Hold the small button to the right of the DC cover until the front indicator light appears. This powers on the AIO unit.
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.
What to check after a full restart
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.
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.
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.
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.
If a CAN fault persists after a restart — cable, firmware, and BMS causes.
Settings reset after a firmware update that ran during or after restart.
Re-enter your charge and discharge schedule after a firmware reset.

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.
Fault persisting after restart — we'll identify the root cause.
If a fault code returns after a correct restart, there is a persistent underlying cause. Tell us what code you're seeing and what happened before the fault appeared — we review the event log remotely and identify whether it's hardware, firmware, or configuration.
