GivEnergy Inverter or Battery Not Working?
Battery not charging, inverter fault, system offline, BMS warning, incorrect readings or unexplained loss of performance? Mr Solar diagnoses and repairs GivEnergy solar and battery systems, including installations originally fitted by another company.

A GivEnergy warning does not automatically mean that the inverter or battery needs replacing.
Problems can originate from the inverter, battery, BMS communications, metering, CT clamps, AC supply, PV array, cabling, internet connection or system configuration.
Our approach is to establish what is actually causing the problem before recommending repair or replacement equipment.
What Is Your GivEnergy System Doing?
🔴 Inverter Fault
Red warning light, recurring alarm, inverter shutdown, grid fault, GFCI warning or an inverter which will no longer start.
Search inverter fault codes →🔋 Battery Not Charging
Battery remaining at low state of charge, refusing to charge, shutting down or not accepting available solar or scheduled charging.
Check battery fault codes →↔ Battery Not Discharging
The battery appears charged but is not supplying the property when expected, or remains at a fixed state of charge.
Battery fault guide →🔌 BMS Communication Fault
Communication errors between the inverter and battery can involve cables, configuration, firmware, battery condition or the BMS.
See BMS communication faults →📡 System Offline
The system may still be operating even though the GivEnergy app or portal has stopped updating.
Search communication faults →⚡ Meter or CT Problems
Incorrect import/export values, strange house-load readings or unexpected battery behaviour can involve metering, CT orientation or communication issues.
Meter & CT fault guide →☀️ Solar Not Generating
If solar generation has stopped or dropped significantly, the cause may be the inverter, PV array, isolators, cabling or another part of the system.
Check solar-related faults →📉 Low System Performance
Generation or battery performance may deteriorate without the system completely failing. We can investigate where the lost performance is occurring.
🛠 Original Installer Unavailable
We regularly help customers whose original solar installer is no longer available or where a property has been purchased with an existing GivEnergy system.
Do You Already Have a GivEnergy Fault Code?
If your inverter, battery or app is displaying a warning, make a note of the exact code before resetting the system.
Our dedicated GivEnergy fault-code guide covers common:
- BMS communication faults
- Battery low-voltage warnings
- Battery not charging or discharging
- Meter communication faults
- GFCI and insulation faults
- No Utility / grid faults
- Backup overload faults
- Incorrect import and export readings
What We Can Check
- GivEnergy inverter operating status
- Battery state of charge
- Battery voltage
- BMS communications
- Battery charge operation
- Battery discharge operation
- Charging schedules
- Solar PV generation
- PV string voltage and current
- AC and DC isolators
- Meter communications
- CT clamp position and direction
- Import and export readings
- App and portal monitoring
- Wi-Fi and communications
- System configuration
- Electrical protection
- Existing installation condition
We Will Explain What the System Actually Needs
Not every GivEnergy fault requires a replacement inverter or battery.
Where possible we will establish whether the problem can be resolved through configuration, communications, metering, corrective electrical work or another repair.
Repair
Diagnose and correct wiring, metering, communication or installation faults where replacement equipment is not required.
Reconfigure
Review operating modes, charging schedules, reserve settings, metering configuration and system behaviour.
Replace
Where equipment has failed, we can explain suitable replacement options and any compatibility issues with the existing installation.
Know the Error Code Already?
Search the exact message to find the relevant part of the system, possible causes and whether professional diagnostics are recommended.

Initial Guidance
Send us the inverter model, battery model, error code and photographs or screenshots where available.
Diagnostic Visit
Initial inspection and fault finding. Additional electrical testing or corrective work will be discussed if required.
Repair / Replacement
Once the problem has been established, we will explain the options and provide a quotation before additional work is undertaken.
Pricing depends on location, access, equipment and the nature of the fault. Any additional work will be discussed before proceeding.
Your Original Installer Does Not Need to Be Mr Solar
We regularly help customers where the original installer is unavailable, has stopped responding, is no longer trading, or where the property has been purchased with a GivEnergy installation already fitted.
Tell Us What You Have
Send the inverter model, battery model, exact fault message and photographs of the installation where possible.
Initial Assessment
We assess the symptoms and determine whether an on-site diagnostic visit is likely to be required.
Test & Diagnose
We investigate the system rather than automatically assuming that the inverter or battery needs replacing.

GivEnergy Repairs FAQs
Can you repair a GivEnergy system installed by another company?
Yes. We diagnose and repair solar and battery systems originally installed by other contractors. Manufacturer warranty access may depend on the equipment, installation history and individual circumstances.
Does a fault code mean my inverter has failed?
Not necessarily. A fault code identifies an operating condition but the cause may be elsewhere in the installation, including the battery, metering, communications, PV array or AC supply.
Why is my GivEnergy battery not charging?
Possible causes include schedules, operating mode, reserve settings, BMS communication, meter information, battery condition or an inverter fault. Proper diagnosis is preferable to replacing components unnecessarily.
Why has the GivEnergy app stopped updating?
The system may still be operating normally. Monitoring problems can result from an internet, dongle, communication or portal connection problem rather than a failed inverter.
Where can I find my GivEnergy fault code?
Check the inverter display, system status and GivEnergy monitoring platform. If a warning is shown, copy the exact wording or take a screenshot and use our GivEnergy Fault Code Guide .
