How to Update GivEnergy Firmware — Inverter & Battery Software Guide
GivEnergy firmware updates improve stability, add features, and fix bugs — but they also reset certain settings and occasionally introduce new issues. This guide covers the update process, the one-hour stall rule, and the four settings you must check after every update.
Firmware updates can silently reset charge schedules, export limits, and EPS settings. If your system stopped working correctly after an update, a remote review identifies which settings changed and restores correct operation.

Before you update
A firmware update should take 5–30 minutes with a working internet connection. Preparing properly avoids the most common failure modes.
Note your settings before updating
GivEnergy firmware updates — especially major version updates — can reset the following settings to factory defaults: charge schedule windows and target SOC values, export limit, CT clamp direction, and EPS mode on/off. Screenshot or write down your current settings before initiating an update. This makes it trivial to restore them if they change.
Remote portal firmware update
The remote update is the standard method for most GivEnergy systems. It updates both the inverter and battery firmware in sequence, without any physical access to the equipment.
Step-by-step
Sign in with your registered email and password. Confirm your system is showing as online on the dashboard — live data should be updating.
From the dashboard sidebar, select My Inverter Card. In the My Inverter section, select Software. If your system is already running the latest firmware, no update option will appear. If an update is available, you'll see an Update button with the new version number.
Click the Update button. The portal will show 'Updating' status. The process begins immediately. Do not navigate away from the page and do not turn off the system.
The update typically completes within 30 minutes. The inverter display may flash, go dark, or restart during this time — all normal. The portal status will change from 'Updating' to showing live data again when complete.
Return to My Inverter → Software and check the current firmware version. It should show the version you were prompted to update to. If it still shows the old version, the update may have failed — see the stalled update section below.
Update stuck — the one-hour rule
If the portal still shows 'Updating' after one hour, the update has stalled. This is a known behaviour — it does not necessarily indicate hardware damage.
Recovery procedure
Locate the AC isolator — this is the switch on the wall below the inverter. Turn it off. Wait 30 seconds. Turn it back on. The inverter will restart and attempt to complete or resume the update.
After the restart, wait 10 minutes for the system to reconnect and the portal to refresh. Check the firmware version in My Inverter → Software. In most cases, the update completes successfully after the restart.
Check the inverter display directly. If it shows a fault code, note it and look it up in the GivEnergy fault codes guide. A completely blank display after restart may indicate a more serious firmware corruption requiring manufacturer recovery — contact GivEnergy support or book a remote diagnostic.
Do not restart before one hour
Restarting too early — while firmware is still being written — can corrupt the flash memory and cause more serious problems. The one-hour mark is the safe recovery point recommended by GivEnergy. If the update is 45 minutes in and you're anxious, wait the extra 15 minutes.
Settings to check after every firmware update
These four settings are most commonly reset by GivEnergy firmware updates. Check them every time — even minor updates can affect them.
Check all Timed Charge, Timed Discharge, and Timed Export slots are still present and set to your intended times and target SOC values.
Charge schedule guide →If you have a DNO export limit requirement (typically 3.68kW for a standard domestic connection), verify it's still set correctly. A reset to 0 or to the inverter maximum can cause export limit compliance issues.
Export limit guide →The CT clamp direction setting can revert to default after updates. Check the portal Charts for the morning after the update — if the grid line shows the opposite of what you'd expect, the CT direction may have flipped.
CT clamp guide →If you rely on Emergency Power Supply for power cut backup, verify EPS is still enabled and that the minimum SOC reserve is set correctly after the update.
EPS not working guide →Also check monitoring connectivity
Some firmware updates affect the dongle's cloud connection behaviour. If the portal shows the system as offline after an update, power cycle the dongle (turn off the AC isolator for 30 seconds). Also check whether your WiFi dongle has a separate firmware update available — dongle and inverter firmware updates are managed separately. See the WiFi dongle guide for dongle-specific update instructions.
Dongle firmware is separate from inverter firmware
The GivEnergy portal remote update covers the inverter and battery. The WiFi dongle has its own firmware that is managed separately. For newer AECC dongles, firmware updates are applied via the dongle's local web interface and should only be done when instructed by GivEnergy. For older HF21/HFA21 dongles, the chipset can be updated to T27 to improve compatibility with modern routers.
Available via the dongle's Software Upgrade page at 10.10.100.254. Only update when GivEnergy advises you to — factory-installed versions are tested for your hardware combination. Uninstructed updates can cause connectivity issues.

Log in to givenergy.cloud, go to My Inverter Card > Software. If an update is available, press Update. The process takes 5–30 minutes — do not turn off the system during this time. If no update option appears, your system is already running the latest available firmware.
If the portal shows 'Updating' for more than one hour, turn off the inverter at the AC isolator for 30 seconds, then turn it back on. Wait 10 minutes and check the portal — the update should have completed. Do not restart before the one-hour mark as this risks firmware corruption.
Firmware updates can reset charge schedules to factory defaults. Go to the portal Settings and re-enter your Timed Charge and Timed Discharge slots. Also check your export limit, CT clamp direction, and EPS mode settings — all four are commonly reset by major firmware updates.
Generally yes — firmware updates fix bugs, improve stability, and add features. However, if your system is currently working well, wait a week or two after a major release to allow any early-adopter issues to surface on forums. If GivEnergy pushes the update automatically, you have no choice. After any update, check your four key settings: schedule, export limit, CT direction, and EPS mode.
System not right after a firmware update?
We restore GivEnergy systems to correct operation after firmware issues — checking what changed, re-applying the correct settings, and confirming the system is working as it should. Remote session, no site visit in most cases.
Need help with a firmware update?
If a firmware update has caused unexpected behaviour, reset your settings, or you're not sure whether to update — we can review your system remotely and advise.
