I've just raised a ticket via the app as I also have this issue.

When we started off with an 8kw battery system it always seemed our system used around 40watts extra an hour for a house load of 200 watts or less.

Ours is a h1 inverter so I'm not sure versions will be of much help, versions being: Master Version 1.63 Slave Version 1.02 Manager Version 1.68 But the updates have helped so it's possible any newer update may also improve your system.

I am not sure if this will help but it could be worth making sure your system is using the latest versions.

I found our system using around 90 watts but since getting an update a few months ago the usage is more like 27watts.

A few weeks ago I got Fox support to update our system and the versions are as follows;

Inverter Model : H1-3.7-E
Master : 1.58
Slave : 1.02
Manager : 1.61
