Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.
Called back within a day and gave good advice.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.

A red light is a protection state, not an immediate danger — but two scenarios require immediate action before any investigation.
If you smell burning, see scorch marks, or hear arcing — stop immediately
Isolate the system at the consumer unit (turn off the solar / inverter breaker). Do not investigate further. Call a qualified engineer. Do not attempt to restart the system.
The GivEnergy inverter and battery are separate units, each with their own status light. The inverter is typically wall-mounted (garage, utility room, loft). The battery is a separate floor-standing or wall-mounted unit nearby. Identifying which has the red light is the most important first step — the causes and responses are completely different.
Is the light solid red, or is it flashing? If flashing — how many flashes, at what speed, is there a pause between sequences? Take a short video on your phone if possible. Different flash patterns indicate different fault types and this information is critical for diagnosis.
Log into givenergy.cloud → My Inverter → Event Log. The event log shows the exact fault codes that triggered the red light, with timestamps. The fault code is the single most valuable piece of information — it identifies the specific cause far more precisely than the light pattern alone. Take a screenshot.
According to the GivEnergy user manual, the status light system is the same on both the inverter and the battery pack. Understanding all colours helps confirm the red light is a fault rather than a normal operating state.
System operating normally. No action required.
Inverter only — waiting for available power to manage. Normal at night or during low-generation periods.
Lost communication — typically WiFi/portal offline or CAN bus issue. System may still be generating. See portal offline guide.
System has detected a fault and entered protection state. Check portal event log for specific fault code. Do not open enclosures.
The inverter status light is on the front panel of the wall-mounted inverter unit. A red light means the inverter has detected a fault and stopped generating. The portal event log will show the specific fault code — this is the fastest route to identifying the cause.
INV_NO_UTILITYNo AC supply detected. Check the AC isolator below the inverter is on and AC connections are tight.STORAGE_ERROR_NO_UTILITYSame as above on the storage variant. Check AC supply and isolator first.INV_PV_OVER_VOLTAGEString voltage from panels exceeds 580V DC. Do not touch any DC cabling. Requires an engineer to check panel string configuration.INV_GFCI_FAULTGround fault detected — DC voltage to earth. Do not touch DC cabling. Isolate at the consumer unit and call a qualified engineer immediately.STORAGE_ERROR_GFCI_FAULTSame ground fault on the storage variant. Same response: isolate and call an engineer.A small switch or isolator is typically mounted on the wall directly below the inverter. This must be in the ON position. If it has tripped, reset it. If it trips again immediately, do not force it — there is an underlying fault.
Check your consumer unit for any tripped RCDs or MCBs on the solar circuit (typically labelled PV, Solar, or Inverter). Reset if tripped. If it trips again, stop and contact an engineer.
If no breakers are tripped and the isolator is on, try a controlled restart: turn the AC isolator off, wait 60 seconds, turn it back on. Allow 5 minutes for the inverter to go through its startup sequence and reconnect to the grid. Check the portal after 10 minutes.
The GivEnergy battery has a status indicator on its front panel — the same three-colour system as the inverter: green (normal), yellow (communication issue), red (fault). The battery also has four SoC indicator LEDs showing 25%/50%/75%/100%. The GivEnergy user manual states explicitly: "If you see a red status light on the front panel, please contact your installer."
Battery restart procedure
The green or red handled switch between the two units. Move it to the DOWN / OFF position.
Press and hold the button on the side of the battery until all LEDs go out. Leave off for at least 60 seconds.
Press the side button to restart. Watch the status indicator — if it returns to green, the fault may have been a transient protection event that has now cleared. Then move the DC MCB back to ON. Wait 5–10 minutes and check the portal.
STORAGE_WARN_BMS_COM_FAILInverter lost communication with the battery BMS. See CAN fault guide.STORAGE_ERROR_BMS_COM_FAILFull BMS communication error — persistent comms loss.STORAGE_WARN_BMS_UNDER_VOLTAGEBattery at critically low voltage. Check battery is switched on and first SoC LED is green.STORAGE_ERROR_BAT_UNDER_VOLTAGE_FAULTBattery voltage below safe minimum threshold.STORAGE_WARN_BATTERY_SOC_LOWState of charge critically low.STORAGE_WARN_BMS_SHORT_CURRENT_DISCHARGERPolarity issue on DC battery cables. Do not touch any cabling — contact an engineer.STORAGE_ERROR_BACKUP_OVERLOAD_FAULTEPS load exceeds the inverter's power rating. Reduce the load connected to the backup circuit.STORAGE_WARN_BATTERY_VOLTAGE_LOWBattery voltage is low. Check the battery is switched on and the DC MCB is in the ON position.The GivEnergy battery front panel has two separate indicator systems. Understanding both helps interpret what the battery is telling you at the moment of a fault.
Note the number of SoC LEDs lit at the time of the fault — this is useful context for diagnosis, particularly for over-discharge scenarios.
Whether the restart cleared the light or not, the same next step applies: understand what caused it, and confirm it won't recur.
The fault was likely a transient protection event that has cleared. However, it will recur if the underlying cause isn't addressed. Check the portal event log for what code appeared, and investigate whether that condition could repeat — was it an over-discharge during a grid outage? A voltage spike? A momentary CAN loss?
If you cannot identify the cause from the event log, a remote diagnostic reviewing the full event history will establish whether this is a one-off or the start of a recurring pattern.
The fault is persistent. Do not keep restarting. The portal event log has the fault code — this is the starting point for the diagnostic. Share the specific code and the sequence of events leading up to it.
Depending on the fault code, this may be resolvable remotely (firmware mismatch, configuration issue) or may require a site visit (cable fault, hardware failure, BMS board replacement). A remote diagnostic confirms which before you commit to any physical work.
The red light tells us something is wrong. The event log tells us what. If you can share the specific fault code from your portal, we can often identify the cause and recommended fix without a diagnostic session.
