H1 G2 5.0kW Firmware

Morning all,

I am being offered a firmware update on my inverter via the app:

Data Logger 2.09 -> 2.10
Manager 1.41 -> 1.45
Master 1.55 -> 1.59

I can see these latest versions in Wills spreadsheets but in his "release notes" tab I can't find a link or any information on what is changed or fixed.

Can anyone point me in the direction of some info please? Should I upgrade?

The only other source of release notes is from Fox https://fox-ess.tech/firmware-release-notes/
But they are woefully out of date, and they have promised that very soon they will be back on track to release notes... it's been ages though!

Odds are that you will be fine to apply the updates, they usually bring in stability. Also if there was some bad issue, then you can reach out to support and they will rollback to an earlier release, or sometimes push an early next version in some cases.
