GivEnergy Fault Codes – Inverter, Battery & BMS Error Guide
Search common GivEnergy inverter, battery, BMS, meter, grid and communication faults and find out what the warning means and what should be checked next.
Search Your Fault Code GivEnergy Repairs & DiagnosticsWhat Does Your GivEnergy Fault Code Mean?
A GivEnergy fault code does not automatically mean that your inverter or battery has failed.
A warning can be caused by the battery, inverter, BMS communication, electricity meter, CT clamp, AC supply, solar PV array, wiring, configuration or internet connection.
The fault code is therefore the starting point for diagnosis rather than proof that a particular component needs replacing.
If the same fault repeatedly returns, avoid continually resetting it. A recurring warning normally needs the underlying cause identified.

| Fault / Warning | Area | What It Indicates | What Should Be Checked |
|---|---|---|---|
| Latest datapoint not recent | Monitoring | The online portal has not received a recent datapoint from the inverter. | Check whether the communications dongle has a stable connection and whether the inverter is still reporting to the internet. |
| Meters Not Enabled | Meter | The commissioning configuration is not expecting the installed meter or meters. | Meter configuration should be checked within the installer commissioning settings. |
| Meters enabled but not being read | Meter | The inverter expects a meter but is not receiving valid communication from it. | Meter communication wiring, connection and the correct inverter communication socket should be checked. |
| INV_PV_OVER_VOLTAGE | Solar PV | The inverter is detecting excessive voltage from the PV strings. | PV string voltage and system design should be checked. Do not repeatedly restart an inverter showing an over-voltage fault. |
| INV_NO_UTILITY | Grid | The inverter cannot detect its normal AC grid supply. | Check whether there is a power cut and whether the AC supply and external isolator appear to be on. Electrical testing may be required. |
| INV_GFCI_FAULT | Solar PV | A ground-fault / DC-to-earth condition has been detected. | The PV array and DC wiring normally require professional insulation and earth-fault testing. |
| STORAGE_ERROR_PV_OVER_VOLTAGE | Solar PV | PV input voltage is above the expected inverter operating range. | PV string voltage should be measured and compared with the requirements of the inverter. |
| STORAGE_ERROR_NO_UTILITY | Grid | The storage inverter cannot detect the expected AC grid supply. | AC supply, isolators, protective devices and connections should be checked. |
| STORAGE_ERROR_GFCI_FAULT | Solar PV | A possible DC-to-earth or insulation condition has been detected. | Professional testing of the PV strings and associated DC installation is recommended. |
| STORAGE_ERROR_BACKUP_OVERLOAD_FAULT | EPS | The connected backup / EPS load is greater than the inverter is designed to supply. | Reduce the load on the backup supply. If the warning remains with minimal load, professional diagnosis may be required. |
| STORAGE_WARN_BMS_UNDER_VOLTAGE | Battery | The battery-management system is reporting an under-voltage condition. | Check that the battery is powered on. Persistent under-voltage warnings should be diagnosed rather than repeatedly reset. |
| STORAGE_WARN_BMS_SHORT_CURRENT_DISCHARGER | Battery | The battery system has detected a discharge-current / battery connection condition. | Battery DC polarity and connections should be checked by a competent person. Do not alter battery cabling yourself. |
| STORAGE_WARN_BMS_COM_FAIL | BMS | Communication between the inverter and the battery-management system has been lost or is unstable. | BMS communication cable, connectors, battery status and configuration should be checked. |
| STORAGE_WARN_BATTERY_VOLTAGE_LOW | Battery | The inverter is reporting low battery voltage. | Confirm that the battery is powered on. Persistent low voltage may require battery voltage and BMS diagnostics. |
| STORAGE_ERROR_BAT_UNDER_VOLTAGE_FAULT | Battery | Battery voltage has fallen below the expected operating range. | Battery power status, voltage and communication should be checked. |
| STORAGE_WARN_BATTERY_SOC_LOW | Battery | The battery has reached a low state of charge. | Battery status, charging behaviour and operating settings should be checked if the warning persists. |
| STORAGE_ERROR_BMS_COM_FAIL | BMS | Communication between the inverter and battery BMS has failed. | Check battery power, BMS communication cable and system configuration. |
| ELECTRICITY_METER_COM_FAIL | Meter | The inverter is unable to communicate correctly with the electricity meter. | Meter communication wiring, connection, polarity and correct inverter socket should be checked. |
| Battery-not-charging | Battery | The system is not charging the battery from available excess energy as expected. | A normal system restart may clear a temporary condition. If the problem returns, battery operation, settings, metering and communications should be diagnosed. |
| Battery-not-discharging | Battery | The battery is not discharging to meet demand when expected. | Check battery operating mode, reserve, schedules and state of charge. Persistent problems require further diagnosis. |
| Grid Voltage – Too High | Grid | Grid voltage is outside the acceptable upper operating range. | AC connections and actual supply voltage should be checked. Persistent network-voltage problems may require involvement from the local DNO. |
| Grid Voltage – Too Low | Grid | Grid voltage is below the inverter’s acceptable operating range. | AC supply and connections should be checked. Persistent network voltage problems may require DNO investigation. |
| Incorrect Home Power | CT / Meter | Home consumption, grid import or export information does not appear correct. | CT direction, meter power and communication polarity, and monitoring of other generation sources should be checked. |
| Specific Battery Capacity Incorrect / Missing | Battery | One or more battery packs are not being correctly recognised. | Check battery power, DC protection and BMS communications. Installer or manufacturer support may be required. |
| Battery Count Incorrect | Battery | The system is not correctly detecting the number of installed battery packs. | Battery packs should be checked for power and correct BMS communication. |
| Battery Firmware Version | Battery | One or more batteries may not be reporting the expected firmware version during commissioning. | Firmware work should follow the correct manufacturer process. If you are unsure, do not attempt battery firmware changes without appropriate guidance. |
| No Batteries Installed / Detected | Battery | The inverter or commissioning system is not detecting an installed battery. | Battery power, DC protection, BMS communication and commissioning configuration should be checked. |
| Battery Voltage / Activation Issue | Battery | During commissioning, some inverter/battery configurations may require sufficient inverter generation before battery activation. | The correct commissioning procedure for the particular inverter and battery model should be followed. |
| PV Generation Missing / Incorrect | Solar PV | Expected solar generation is not being detected or displayed. | Check that the PV inverter is generating, that the relevant CT is correctly positioned and communicating, and on hybrid systems that the PV strings are connected correctly. |

Fault Keeps Coming Back?
A recurring code usually needs more than repeatedly restarting the inverter.
Mr Solar can investigate the inverter, battery, BMS, PV array, meter, CT clamps, communications and wider electrical installation to establish what is actually causing the problem.
GivEnergy Repairs & DiagnosticsWe Look Beyond the Fault Code
The warning identifies where to start looking, but a proper diagnosis can involve several parts of the installation.
Inverter & System Data

GivEnergy Fault Code FAQs
Can I reset a GivEnergy fault myself?
Some temporary faults may clear after a normal manufacturer-approved restart. However, if the same warning returns, repeatedly resetting the system without identifying the cause is not recommended.
Does a GivEnergy BMS communication fault mean the battery has failed?
No. A BMS communication fault identifies loss of communication between the inverter and battery-management system. The cause may involve the communication cable, connectors, battery power, configuration or another communication issue.
Why is my GivEnergy battery not charging?
Possible causes include system operating mode, battery state, metering information, BMS communication, settings or a fault elsewhere in the installation. The exact cause needs to be diagnosed from the system information.
Why is my GivEnergy battery not discharging?
The battery may have reached its reserve level, be restricted by operating settings or schedules, or there may be a battery, communications or metering problem.
What does ELECTRICITY_METER_COM_FAIL mean?
It indicates that the inverter is not communicating correctly with the system electricity meter. The meter communications, connections and configuration should be checked.
What does INV_NO_UTILITY mean?
The inverter is not detecting its normal AC grid supply. This can occur during a power cut or where there is an AC supply, connection, isolator or electrical problem.
What does a GFCI fault mean?
GFCI-related inverter faults can indicate a potential leakage or DC-to-earth insulation issue. The PV system should be properly tested rather than repeatedly reset.
