I contacted STS when I was having problems with my GivEnergy AC3 inverter and they were extremely helpful. They took the time to properly investigate the system, talked me through a number of things we could try remotely, and ultimately inspected the system to establish what had gone wrong. They identified that the inverter’s battery board had failed beyond repair, while confirming that the two batteries themselves were still healthy. They also provided a clear report explaining their findings, which was particularly helpful given the current situation with GivEnergy. What impressed me most was their knowledge and willingness to help. They didn’t just give me a quick diagnosis — they took the time to understand the problem and explain the options available to me. I’m very pleased with the service I received from STS and would have no hesitation in recommending them to anyone needing help with a GivEnergy solar and battery system.

Diligent and reliable service.
Very speedy response. Handled by a real human who took my system through a logical process with the desired outcome within minutes of them accessing my inverter settings. Ron passed me on to Ash, they are both ex-Givenergy people who clearly know their stuff and can give the reassurance of proper technical support now that the Givenergy support desk has closed. A worthwhile investment in ensuring my expensive kit is kept fully functioning.
Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.
Had issues with 10yr+ installation. 1 inverter going into alarm mode, unable to access monitoring apps and wanted someone to review and document worthiness of the 2 systems I have. As you will find with older systems, the original installers have moved on, other companies only want to replace and install new, or make up silly prices as they don't want the work, so struggling for 18 month plus trying to source someone to do this. Ronald managed to fit me in the day after contact as he was in the area. Spent a couple of hours on site, found issue with the inverter alarm and he monitoring this to find a total solution, got me back onto the monitoring apps, provided a report on the installations and identified potential areas of concern. These are the people you need for diagnostic reviews of your installations, long term industry professionals, who have a wealth of knowledge gained through working in the industry, know the differing systems and how to contact and approah the companies involved. These are the people you need if you are having issues with installers and / or product and/or supply companies.
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
Step 0: Disable external controls first
Before running any software diagnostics, disable all external control integrations. This isolates the GivEnergy system and identifies if the problem is caused by a third-party controller.
Integrations to disable: Energy supplier integrations (Octopus, EDF), Home Assistant, GivTCP, third-party optimizers, and any other automation tools connected to your system.
After testing with all external controls disabled, re-enable them one at a time and test after each. This pinpoints which integration — if any — is causing the fault.
3 portal checks that solve most software issues
These three checks are the first thing to do when a GivEnergy system isn't behaving as expected. They take under five minutes in the portal and eliminate the most common software-level causes.
The givenergy.cloud portal and the GivEnergy app are run by GivEnergy Software Ltd, which is still trading. It is a separate company from GivEnergy Ltd, which is in administration, so the portal is still running and accounts and logins sit with GivEnergy Software Ltd. Companies House showed a proposal to strike GivEnergy Software Ltd off from 15 September 2026, suspended on 30 September 2026, and its parent company changed to IEMCS Limited from 11 August 2026 (checked 24 October 2026). The portal is part of GivEnergy's Premium plan. Without it, the free app (version 4.0.5 or later) can change settings in local mode, with your phone on the same home network as the inverter. Our administration guide sets out what has and has not changed.
Go to givenergy.cloud → My Inverter → Remote Control (the cog icon). Check the battery pause state. If it shows Paused, this single setting overrides everything — no charging, no discharging, regardless of mode or schedule. This is the most overlooked setting in portal diagnostics. Set to Not paused to restore normal operation.
Navigate to My Inverter → Settings tab. For most homes Eco Mode should be on. If you charge from the grid overnight, check that a Timed Charge window is set and enabled, with the right times and target state of charge. Firmware updates commonly change these settings and blank the schedule without warning.
Use the Jump to Logs option in the portal to open the event log. Review recent entries for any fault codes, temperature events, or communication errors. The event log tells you exactly what happened and when — it's essential for any diagnosis that goes beyond a simple settings check.
Checking and resetting charge/discharge schedules
GivEnergy schedule settings are found in the Settings tab. Firmware updates are the most common cause of schedule loss — always check here after any update notification.
Where to find the schedule settings
Log into givenergy.cloud and navigate to My Inverter.
Click the Settings tab (not the Overview or Monitoring tabs).
Scroll to the charge and discharge schedule sections. You should see time slots for your charge and discharge windows.
If the schedule is blank or shows incorrect times, clear all entries and re-enter your required schedule. For overnight grid charging, confirm the Timed Charge window is enabled and leave Eco Mode on.
Why firmware updates reset your schedule
GivEnergy inverter firmware updates — which can happen automatically overnight — are known to reset the system mode to Eco Mode and clear charge/discharge schedules. This is not specific to any one firmware version; it has been observed across multiple GivEnergy releases.
If your battery suddenly stops charging overnight and you haven't changed any settings, always check the Settings tab first. The firmware update timestamp will appear in the event log — if a reset happened just before your schedule stopped working, the update is the cause.
Portal reset vs App reset — which one to use?
GivEnergy provides schedule reset options in both the portal and the app. GivEnergy's own diagnostic guide, written before the app gained its local mode in May 2026, says the portal reset is more thorough and to use the portal for diagnostics: in the Settings tab, Reset settings to default clears all schedules so you can start fresh.
The web portal is part of GivEnergy's Premium plan. Without it, the free GivEnergy app (version 4.0.5 or later) can still clear and re-enter schedules in local mode, with your phone on the same home network as the inverter. Whichever you use, check the slots afterwards to make sure the old entries have gone.
Midnight rule — slots cannot cross midnight
GivEnergy's schedule system has a limitation: a single time slot cannot cross midnight. If your cheap-rate window runs from 23:30 to 05:30, you cannot enter this as a single entry. You must split it into two slots:
Slot 2: 00:00 → 05:30
Entering a single slot that crosses midnight will either fail to save, save incorrectly, or result in the battery not charging during part of the window. Always split overnight schedules into two entries.
Using Remote Control to check and override battery state
The Remote Control cog in the GivEnergy portal allows you to manually override the battery's operating state. It's a powerful diagnostic tool and the place to check when the battery simply isn't doing anything.
Finding Remote Control in the portal
Navigate to givenergy.cloud → My Inverter. Look for the cog icon () or the Remote Control option in the navigation. This is separate from the Settings tab — it provides real-time manual control of the battery.
The battery pause state — most overlooked diagnostic check
In Remote Control, the Pause Battery setting completely overrides all other control. If it is set to Paused, the battery will not charge or discharge under any circumstances — regardless of the schedule, the system mode, the SoC, or anything else.
This setting is left in the Paused state more often than you'd expect. Engineers sometimes pause the battery during diagnostic work and don't restore it, or it gets set via the app and forgotten. Always check this first when the battery appears completely inactive.
Go to Remote Control → Battery.
If it shows Paused, change to Not paused and save.
Wait 5 minutes and check the monitoring dashboard — the battery should now respond to the active schedule and mode.
Using Force Charge to test battery hardware
The Force Charge option in Remote Control commands the inverter to charge the battery immediately from the grid. This is a useful diagnostic test — if the battery charges correctly when Force Charge is active, the hardware is functioning and the issue is a settings or schedule problem, not a component fault.
Reading the GivEnergy event log
The event log is the single most valuable diagnostic tool in the GivEnergy portal. It records every system event with a timestamp — faults, warnings, temperature events, communication errors, and firmware updates.
How to access the event log
Log into givenergy.cloud and go to My Inverter.
Use the Jump to Logs option or navigate to the Event Log tab. This shows a timestamped list of all system events.
Filter by date to focus on the period when the problem started. Compare the event log timestamp with when normal operation last occurred to identify what changed.
What to look for in the event log
Any numeric fault codes should be noted and checked against the GivEnergy fault code guide. Codes starting with E indicate errors; W indicates warnings.
Firmware updates appear in the log. If a schedule reset or mode change coincides with a firmware update timestamp, the update is the cause.
BMS temperature protection events appear here — if the battery cell temperature dropped below 0°C and charging stopped, this will show clearly in the log.
BMS communication errors (BMS Comm Fail) between the inverter and battery will appear here. Intermittent communication loss can cause inconsistent battery behaviour even when the system appears normal.
Understanding GivEnergy system modes
The mode settings determine how the GivEnergy inverter manages charging and discharging. Eco Mode is the everyday setting, and a Timed Charge window works alongside it rather than replacing it. Many apparent faults are actually the correct behaviour for the wrong settings. This table shows the key differences.
| Mode | Charges from grid? | Charges from solar? | Use for |
|---|---|---|---|
| Eco Mode | Not on its own: add a Timed Charge window | Yes | Everyday running. Stays on alongside a Timed Charge window |
| Timed Charge | Yes, during the set window | Yes | Cheap-rate overnight charging (Go, Agile, E7), with Eco Mode left on |
| Timed Discharge | No. A Timed Charge window overrides it | Yes | Choosing when the battery meets the home's demand, for example at peak times |
| Timed Export | Not while it is exporting | Not while it is exporting | Peak export rate windows. The battery discharges at full or set power: the house load is covered first and the excess goes to the grid |
The most important thing to know about Eco Mode
Eco Mode on its own does not charge the battery from the grid. It charges from surplus solar and discharges to meet the home's demand. If you have a cheap overnight tariff (Octopus Go, Agile, Economy 7, Cosy), set a Timed Charge window with the correct hours and target state of charge, and leave Eco Mode on. Inside the window the battery charges from the grid. Outside it, the system goes back to Eco, charging from surplus solar and meeting demand.
For a full guide to configuring each system mode for different tariffs, see the tariff optimisation guide and the Eco Mode guide.
If the schedule and system mode look correct, the battery isn't paused, and the event log doesn't show an obvious fault — but the system still isn't behaving correctly — the issue is likely something that requires reviewing your historical monitoring data. We analyse charge/discharge graphs, CT clamp readings, and portal event sequences to find the cause.
Physical checks — isolators, LEDs, temperature, and safe restart sequence.

See battery not charging overnight →What Eco Mode does and does not do, and how a Timed Charge window works alongside it.
