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 charging & discharging problems
The most common GivEnergy call-outs. Most have a definitive cause that can be identified from monitoring data alone.
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.
CommonBattery 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.
TechnicalCAN 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.
AlarmStatus light flashing red
Flash patterns indicate different fault states — BMS protection, over-temperature, cell imbalance, or communication loss. Do not open the unit.
SeasonalCold 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.
FirmwareSOC 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.
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.
Portal offline or not updating
App or givenergy.cloud shows no data. Covers WiFi dongle faults, WiFi dongle hardware failure, cloud-side outages, and firmware updates that broke connectivity.
CommonSettings changing themselves
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.
Smart tariff lockout
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.
Firmware issues
System changed behaviour after an update — schedules broken, monitoring stopped, or new fault codes appeared. What to check and how to recover.
Inverter, solar & hardware faults
Faults with the inverter itself, solar generation, EPS backup power, EV chargers, and error codes that indicate a component issue.
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.
NewEV 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.
CommercialCommercial 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.
How we approach GivEnergy fault diagnosis
Diagnostic methodology
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.
Independent second opinion
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
