GivEnergy Settings Changing Themselves — Why It Happens and How to Stop It

You set your GivEnergy charge schedule or system mode, confirm it's saved — and within hours, days, or after the next firmware update, it has reverted. This is one of GivEnergy's most frustrating recurring issues and it almost always has an external cause: a smart tariff API, an Axle Energy grid event, a third-party integration, or a firmware reset. This guide walks through each cause and how to stop it.

Excellent knowledge and service. Ron responded to my initial query really quickly (same day), and confirmed that he could add extra panels and battery to my existing GivEnergy setup - something I’d been told by other installers wouldn’t be possible. Two weeks later (!), scaffolding was up and Ron and his team were on site to fit the extra 5 panels and two more GivEnergy batteries. I now have a truly optimised system, which has made the most of the south facing roof space I have, without having to start again with new kit. I’m now generating enough on the solar to fill my batteries, and avoid using the grid. I’ve also exported far more than before. Brilliant experience, well recommended.

Solar Tech Support answered my initial enquiry swiftly. They provided remote support to establish what the issue was, and through their experience and network, managed to get my clients system back online. Once the system was online, STS managed to diagnose the main issue to get the ac coupled inverter and battery back online, a battery repair was required. A site visit was organise and within a few days, the system was tested and back up and running. This has saved my client, and probably myself huge costs and inconvenience now the system is back online and working correctly. Would highly recommend.

Identify

Use the timing to identify what's changing your settings

The timing and pattern of when settings revert narrows down the cause significantly. Before diving into each cause, use this to focus your investigation.

REVERTS WITHIN MINUTES

An active API connection is overriding your settings in near real-time. The most common cause is a smart tariff integration (Octopus Intelligent, Agile, Flux) that currently has control, or an Axle Energy grid event in progress. Start with Smart Tariff API.

REVERTS OVERNIGHT OR DAILY

A scheduled automation is running at a set time and writing settings to the inverter. Check for GivTCP or Home Assistant automations that run at a fixed time, or check your Axle Energy account for a scheduled grid event.

REVERTS AFTER FIRMWARE UPDATE

The firmware update reset your settings to defaults. This is a known GivEnergy behaviour. See Firmware Reset for which settings are affected and how to prevent it recurring.

SETTINGS APPEAR GREYED OUT

The portal or app is showing settings as locked or uneditable. This is a Smart Tariff Lockout — the energy provider has exclusive write access to certain settings. See our dedicated Smart Tariff Lockout guide.

Cause 1 — most common
Smart tariff API

Your energy provider has API access to your inverter

Smart tariffs like Octopus Intelligent, Agile, and Flux work by giving the energy provider API access to compatible devices — including GivEnergy inverters. When you signed up for one of these tariffs and connected your GivEnergy account, you authorised the provider to read and write your inverter settings automatically.

Which tariffs have GivEnergy API access

Octopus Intelligent

The most common cause. Octopus Intelligent dispatches charge sessions during off-peak periods and may override your charge window times and system mode. The system is designed to optimise overnight charging — but it actively pushes settings to the inverter, which means your manual settings are overwritten whenever Octopus runs a dispatch.

Octopus Flux

Flux uses a three-period day (cheap, expensive, export) and sets charge and discharge windows to align with the price periods. If connected, Flux overrides your manual schedules to manage battery charge and discharge in line with its pricing model.

Octopus Agile

Agile integration is less aggressive than Intelligent but can still set charge windows during cheap rate periods. The degree of control depends on whether you opted in to smart charging features within the Octopus app.

How to confirm it's API-caused — and check who's making the changes

1
Go to the Remote Control page in the portal

Navigate to: givenergy.cloud/inverter/YOUR-SERIAL/remote-control — replace YOUR-SERIAL with your inverter's serial number (printed on the unit or in your installation docs). Alternatively: My Inverters → click the cog icon next to your inverter.

2
Scroll to Control Logs — check the VIA column

The Control Logs table shows every settings change. The VIA column tells you how each change was made: API = an external third-party integration (tariff provider, GivTCP, Home Assistant). SERVER = a GivEnergy platform automation (Smart Tariff card). Adjust the date range to show the period when changes occurred.

VIA API: An external service is writing to your inverter. Check givenergy.cloud/account-settings/security, the address GivEnergy Software gives for removing a connected service, to see which service is responsible. Contact that provider, or remove its access there.

VIA SERVER: A GivEnergy platform automation is active. Go to your Dashboard → Smart Tariff card and check whether any automations are enabled. Disable them to stop the changes.
3
Review and remove connected services

Go to givenergy.cloud/account-settings/security, the address GivEnergy Software gives for removing a connected service. Remove any connected service you no longer want. Note: if the integration is linked to a smart tariff with a lockout, you must contact the provider first before removing its access — see our smart tariff lockout guide for the correct process.

Before removing: Smart tariff integrations are often linked to discounted rate benefits. Octopus Intelligent, for example, offers overnight cheap-rate periods in exchange for smart dispatch control. Check your provider's terms — removing API access may affect your tariff pricing.
Cause 2
Grid events

Axle Energy grid events

If your system is in Axle Energy's grid-services scheme, Axle takes over your settings during each grid event. GivEnergy Software Ltd, which runs the GivEnergy app and portal and is still trading, lists "Axle (during an event)" among the things that change GivEnergy settings, alongside the Smart Scheduler, a supplier tariff and Home Assistant. GivEnergy's own scheme, GivBack, has been withdrawn; its app and sign-up pages had gone by October 2026. Our Axle Energy guide covers joining, payments and opting out.

How an event affects your settings

→Just before an event Axle saves your settings and sets a timed export at full power for the event, keeping at least 10% in the battery.
→Events usually last 1 to 2 hours; short-notice events, which are opt-in, can be as short as 30 minutes. Axle emails members the day before a normal event.
→Axle says it puts your settings back afterwards, but its own FAQ admits this sometimes fails and calls it a known issue under repair. If they weren't restored, reset them by hand in the app.
→Axle says events are more frequent in winter.

How to check, and how to stop it

→If you have an Axle account, it shows each event and what the battery did, so compare the time your settings changed with your event history.
→Check which services can control your inverter at givenergy.cloud/account-settings/security, the address GivEnergy Software gives for removing access.
→To stop it, do either one: leave from your Axle account (no exit fee), or remove Axle's access at that address. Either one stops Axle's control.
→Don't recognise a connected service? Remove it yourself: an installer or a previous owner may have connected it, and there is no GivEnergy Ltd support desk to chase.
Cause 3
Integration

Third-party integrations writing to the inverter API

GivTCP, Home Assistant with a GivEnergy integration, and similar tools can write to your inverter, either locally over your home network or through the GivEnergy cloud API. If any of these tools have automations that write settings on a schedule, they will overwrite manual changes made through the portal or app. This is a common issue for homeowners who set up smart home integrations and then try to manage settings manually.

Common third-party tools that write GivEnergy settings

GivTCP

A popular open-source local interface to GivEnergy inverters. GivTCP can both read and write inverter settings. If configured with write automations (e.g., to set charge windows based on Agile pricing), it will push those settings on its schedule — overriding anything you set manually in the portal.

Home Assistant

Home Assistant's GivEnergy integration, combined with automation scripts, can write charge/discharge settings based on time, price, or consumption patterns. If an automation is configured to set a specific system mode at a certain time, it will do so regardless of what you set manually.

Installer tools

Some installers set up remote management access to your GivEnergy system for ongoing support. If the installer's monitoring platform has write access, they — or their automated systems — can modify settings. This is common on newer installations where the installer retains portal access.

How to identify if a third-party tool is responsible

The GivEnergy portal event log records all API write events — including which API key made the change. Go to givenergy.cloud → My Inverter → Event Log. If settings changes are logged at regular intervals (e.g., every night at 23:00) from an API key you do not recognise, a third-party integration is responsible. Changes made locally, for example by GivTCP or by the GivEnergy app in local mode, may not show in the portal log at all, so check the tool's own automations as well.

Finding the API key: Each API access key in the portal is labelled with its purpose and creation date. Go to givenergy.cloud/account-settings/security, the address GivEnergy Software gives for removing access, to see them. You can revoke any key you do not recognise or no longer need. Revoking a key prevents that integration from making any further changes.
Cause 4
Firmware

Firmware update reset settings to defaults

GivEnergy inverters receive over-the-air firmware updates that can run automatically. Some firmware versions reset certain settings to default values — a well-documented pattern that catches GivEnergy owners off guard. The fix is straightforward: re-enter your settings after any update. The GivEnergy app and portal also let you start an update yourself, but we do not advise it. We handle firmware manually, to our own written procedures, on a callout or by talking you or your electrician through it remotely, and put back any settings that changed.

Settings commonly reset by firmware updates

Charge/Discharge settings
→Timed Charge window times and target SoC
→Timed Discharge window — often reset to inactive
→Reserve SoC — often reverts to 50–75%
→Discharge power limit
System settings
→System mode — reverts to Eco Mode
→Export limit settings
→EPS (backup) enable/disable state
→CT clamp direction (rare, but reported)
After every firmware update: Go to givenergy.cloud → My Inverter → Settings, or the same settings in the GivEnergy app, and review all four schedule types (Timed Charge, Discharge, Export, Import), system mode, reserve SoC, discharge power limit, and export limit. It takes under 5 minutes and prevents days of suboptimal battery behaviour.

FAQ

GivEnergy settings questions

The most common cause is a smart tariff connection — if you're on Octopus Intelligent, Agile, or Flux and connected your GivEnergy account, your energy provider has API access and can change settings automatically. The second most common cause is an Axle Energy grid event, if the system has joined that scheme. Check which services can control your inverter at givenergy.cloud/account-settings/security and remove any you didn't deliberately set up.
Yes, this is a known and recurring GivEnergy issue. Firmware updates occasionally reset specific settings to defaults — most commonly the charge window times, reserve SoC, and system mode. After any firmware update, check all your settings in the GivEnergy app or the portal (givenergy.cloud) and re-enter any that have reverted. This is a configuration reset, not a hardware fault.
Yes — remove the smart tariff connection at givenergy.cloud/account-settings/security, the address GivEnergy Software gives for removing access. Once removed, your energy provider can no longer write to your inverter. However, smart tariff integrations are often required for the discounted rate benefits of tariffs like Octopus Intelligent. Revoking access may affect your tariff pricing — check your provider's terms before disconnecting. If you want to keep the tariff benefits but regain manual control, contact your energy provider about their override options.
If there are no smart tariff connections or Axle Energy membership, check whether a third-party tool like GivTCP or Home Assistant is writing to the inverter on a schedule. Also check whether another household member or the original installer still has portal access, or uses the GivEnergy app in local mode: since app version 4.0.5 (May 2026) the free app can control the inverter on your home network without a login. Go to givenergy.cloud → My Inverter → Event Log, which records changes made through the cloud with timestamps; changes made locally may not show there. If settings change at a specific time each day, a scheduled automation is responsible.
No. The app and the inverter are separate: updating the app doesn't change anything stored in the inverter. If settings change after an app update, the cause is almost always something writing to the inverter at the same time, such as a smart tariff (Octopus Intelligent, Flux or Agile), an Axle Energy grid event, or a firmware update that reset registers to defaults.
The remote diagnostic is free — we'll review your portal event log, which records every API write and the source behind it, at no charge and tell you exactly what is overriding your configuration. If it's something we can put right remotely, like revoking a rogue third-party connection or taking you out of a grid-services scheme, that's a flat £125 — and if we can't resolve it remotely there's nothing to pay. There is rarely any need for an on-site visit, since this is all controlled through the portal and the API. You'll always know the price before any work starts. Full pricing →
Usually the same day. Reading the portal event log tells us within minutes whether it is a smart-tariff API, an Axle Energy grid event, a third-party automation, or another account holder making the change — and most of those we can revoke or correct remotely there and then. The one thing worth knowing is that if a smart-tariff integration is involved, keeping the tariff's discounted rate while regaining manual control sometimes needs a quick word with your energy provider too, which we'll guide you through.
