GivEnergy problems & fault guides — every common fault covered
Every GivEnergy fault guide in one place. Each page covers a specific problem with a step-by-step diagnostic path, cause cards, and a clear answer to whether it can be fixed remotely. Select your fault below.
Tell us what you're seeing — error code, LED behaviour, what the app shows, what changed recently. We'll identify the fault and tell you the fastest fix.

Battery charging & discharging problems
The most common GivEnergy call-outs. Most have a definitive cause that can be identified from monitoring data alone.
Charge windows correct but battery stays empty. CT clamp misread, Octopus Intelligent conflict, or incorrect schedule format. Includes the midnight rule and tariff-specific fixes.
See diagnostic guide →Battery shows full but house uses grid. Paused battery, reserve level too high, Export First mode active, or discharge power limit set to zero.
See diagnostic guide →Inverter loses communication with battery over the CAN bus. Firmware mismatch, termination errors, cable faults, or BMS lock state after a protection event.
See diagnostic guide →Flash patterns indicate different fault states — BMS protection, over-temperature, cell imbalance, or communication loss. Do not open the unit.
See diagnostic guide →Battery stops charging below 0°C, capacity drops in cold. Temperature thresholds, winter schedule adjustments, and when it's normal vs a fault to investigate.
See guide →Portal shows grid import despite a charged battery. Normal inverter lag vs sustained configuration issues — and how to tell the difference.
See guide →Solar generating but battery stays empty. Covers system mode, SoC limits, export limit conflicts, CT clamp errors, Timed Discharge clashes, and temperature lockout.
See diagnostic guide →SOC dropping, jumping, or stuck at a fixed value. BMS firmware versions 3007–3022, calibration cycles, and fixes for the battery percentage bug across all generations.
See diagnostic guide →Portal, connectivity & configuration faults
Portal issues, settings that keep reverting, and tariff-related lockouts — often caused by third-party API control or WiFi connectivity problems.
App or givenergy.cloud shows no data. Covers WiFi dongle faults, GivHub hardware failure, cloud-side outages, and firmware updates that broke connectivity.
See diagnostic guide →Charge schedule or system mode keeps reverting without you touching it. Usually an external API — energy provider integration, GivBack, or Octopus Intelligent — overriding your settings.
See diagnostic guide →Settings greyed out or reverting because your energy provider controls the inverter via API. How to identify which service has control and remove the lockout safely.
See removal guide →System changed behaviour after an update — schedules broken, monitoring stopped, or new fault codes appeared. What to check and how to recover.
See diagnostic guide →Inverter, solar & hardware faults
Faults with the inverter itself, solar generation, EPS backup power, EV chargers, and error codes that indicate a component issue.
House goes dark in a power cut despite having a battery. EPS may be disabled in settings, the EPS circuit wired incorrectly, or the battery SoC below the EPS threshold.
See diagnostic guide →GivEnergy EV charger offline, showing fault codes, not charging, or charging slowly. Covers fault codes E001–E0026, configuration modes, and network connectivity issues.
See diagnostic guide →GivEnergy AIO or hybrid inverter with no display, no output, or won't restart. Covers isolator checks, battery deep discharge, firmware failure, and hardware faults.
See diagnostic guide →Zero or unexpectedly low solar output. Covers export limit, DC isolator, grid overvoltage, standby mode, curtailment, and hardware faults — step by step.
See diagnostic guide →Inverter rapidly clicking as it repeatedly tries and fails to connect to the grid. Covers relay failure, AC voltage issues, grid frequency faults, and firmware problems.
See diagnostic guide →Full index of GivEnergy error codes — grid faults, BMS alarms, communication errors, over-temperature events — with cause and safe next steps for each code.

Every fault guide above is based on real GivEnergy diagnostic sessions. We work through each problem using the same approach as a remote session — isolating the cause before recommending any action, rather than swapping parts or factory-resetting without understanding why.
GivEnergy inverters log a lot of useful data in the portal. Battery SOC history, charge/discharge waveforms, fault registers, and CT clamp readings all point directly to the root cause in most cases. That's why the majority of GivEnergy faults — including most CAN faults, schedule issues, and CT clamp errors — are fully diagnosable without a site visit.
If your fault isn't covered by the guides above, or you've worked through a guide and the problem persists, a remote diagnostic session will find the cause. We're independent from GivEnergy and from your installer — so you get an objective second opinion on what's wrong and what actually needs to be done.
GivEnergy problems — common questions
The most common GivEnergy problems are: battery not charging overnight (charge schedule or CT clamp issue), portal offline (WiFi dongle or cloud fault), CAN communication fault between inverter and battery, status light flashing red (BMS protection event), and settings reverting unexpectedly (third-party API control from GivBack or a smart tariff integration). Each fault has its own diagnostic guide in this section.
Yes — the majority of GivEnergy faults can be fully diagnosed and resolved remotely. We review portal monitoring data, firmware logs, CT clamp readings, charge schedule history, and error codes in a single remote session. On-site visits are only needed where the fault requires physical hardware inspection or replacement — for example, a CAN cable rewire, CT clamp repositioning, or component swap.
Before calling anyone: check the charge schedule in the GivEnergy app and confirm windows are set correctly; check the dongle LED (solid = WiFi connected, flashing = WiFi issue); check no third-party service has API control of your battery; check the firmware version hasn't changed recently. Each fault guide above includes a self-diagnosis checklist you can work through in minutes.
Can't find your fault, or the guide didn't fix it?
A remote diagnostic session identifies the exact cause using your monitoring data, error history, and system configuration — then provides a clear repair plan.
