Ronald was great to help me sort out my giv energy inverter issue since company has gone bankrupt in april 26.

Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.

My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate

Battery faults

Battery charging & discharging problems

The most common GivEnergy call-outs. Most have a definitive cause that can be identified from monitoring data alone.

Most common

Battery not charging overnight

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.

Common

Battery not discharging

Battery shows full but house uses grid. Paused battery, reserve level too high, Export First mode active, or discharge power limit set to zero.

Technical

CAN communication fault

Inverter loses communication with battery over the CAN bus. Firmware mismatch, termination errors, cable faults, or BMS lock state after a protection event.

Alarm

Status light flashing red

Flash patterns indicate different fault states — BMS protection, over-temperature, cell imbalance, or communication loss. Do not open the unit.

Seasonal

Cold weather performance

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.

System using grid with full battery

Portal shows grid import despite a charged battery. Normal inverter lag vs sustained configuration issues — and how to tell the difference.

Battery not charging from solar

Solar generating but battery stays empty. Covers system mode, SoC limits, export limit conflicts, CT clamp errors, Timed Discharge clashes, and temperature lockout.

Firmware

SOC bug — battery percentage wrong

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.

Hardware faults

Inverter, solar & hardware faults

Faults with the inverter itself, solar generation, EPS backup power, EV chargers, and error codes that indicate a component issue.

Safety-critical

EPS not working in a power cut

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.

New

EV charger not working

GivEnergy EV charger offline, showing fault codes, not charging, or charging slowly. Covers fault codes E001–E0026, configuration modes, and network connectivity issues.

Inverter not turning on

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.

Solar not generating

Zero or unexpectedly low solar output. Covers export limit, DC isolator, grid overvoltage, standby mode, curtailment, and hardware faults — step by step.

Click of death

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.

Battery DC MCB tripping

The battery isolator (DC MCB) keeps tripping or won't hold when reset. Covers poor cable termination, buck-boost MOSFET failure, and BMS protection events across Gen 1, Gen 2, Gen 3, and AIO systems.

Commercial

Commercial All in One & PCS

The catch-all guide for GivEnergy commercial kit: what the administration means for warranties and support, design limits in the manuals, reported platform faults, and independent O&M.

GivEnergy fault code index

Full index of GivEnergy error codes — grid faults, BMS alarms, communication errors, over-temperature events — with cause and safe next steps for each code.

FAQ

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.
