GivEnergy Red Status Light — Inverter & Battery Fault Guide
A red status light on your GivEnergy inverter or battery means the system has detected a fault and entered a protection state. This guide explains what each light pattern means, which unit is affected, and what to do for each scenario — without opening any covers.
The red light tells you there's a fault — the portal event log tells you what it is. We review your event log remotely, identify the exact fault code and cause, and tell you whether this is a settings fix, a restart, or something that needs a site visit.

Do this before anything else
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.
GivEnergy status light meanings — all colours
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.
Red light on the GivEnergy inverter
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.
Grid / AC fault codes
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.DC / panel fault codes
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.What to check for an inverter red light
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.
Red light on the GivEnergy battery
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."
Common causes of a battery red light
What you can do safely
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.
BMS and battery protection codes
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.EPS and backup circuit codes
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.Battery front panel — status light and SoC indicators
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.
Status indicator (1 light)
SoC indicator (4 LEDs)
Note the number of SoC LEDs lit at the time of the fault — this is useful context for diagnosis, particularly for over-discharge scenarios.
Red light cleared — or still showing. What next?
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.

GivEnergy red light questions
Trust the physical light over the portal if there's a discrepancy. The portal updates every few minutes and may not have received the latest data yet — particularly if the dongle lost connection at the time of the fault. Check the event log specifically (not just the dashboard) for any fault codes. If the event log is also clear but you can see a red light physically, the portal data may simply be delayed.
Quite possibly yes. A battery fault affects the battery operation but does not necessarily stop the solar panels generating. Check the inverter display — if it shows a kW output figure, solar is generating and being used or exported. The inverter and battery are separate units; a battery fault doesn't automatically shut down generation. Check the inverter status light separately.
A red light after a power cut is common and often clears with a restart. Power cuts can cause the inverter to enter a fault state as the grid reconnects (particularly if there was a voltage spike on reconnection), or the battery BMS may have triggered an under-voltage protection if EPS ran the battery flat during the outage. Try the power cycle procedure above. If the light doesn't clear, check the event log for the specific fault code that was triggered at the time of the outage.
The inverter is the wall-mounted box that connects to the AC wiring, typically in a garage, utility room, or loft. Its status light is on the front panel. The battery is a separate unit — usually floor-standing or wall-mounted nearby, with its own front panel status light and four SoC LEDs. Check both units. It's possible to have a red light on one while the other is green — they are separate fault systems.
Red light needs a diagnosis. We can do that remotely.
Tell us which unit has the light, the fault code from the event log if you have it, and what happened leading up to it. We'll identify the cause and confirm whether it needs a site visit before you commit to anything.
