Hi,
Since 1.4.2022 I was in island mode by setting multiplus to inverter mode.
13.9.2022 I switch multiplus from inverter to ON and system not working propertly
Before 1.4.2022 I use ESS whitout any problem more than 2 years.
System looks like don't know what to do and is confused. He floating between feeding to grit (this is not allowed) and charge from grid.

I am completely at a loss what happen.
I upgraded firmware multiplus II
I reset all and setup as new.
I try ET340 change for ET112
I try run only one mutliplus (no parallel)
When I setup in ESS grid metering inverter/charger, system start charging battery despite is not discharge below ess threshold and gradually stop using solar energy
When I setup in ESS grid meter external meter, system looks like in video.
What I noticed on the multiplus II don't show input current, but show input power
System
My system is:
2 x Multiplus II in parallel
ET340
1 x MTTP 250/100
1 x MTTP 250/100 ve.can
BMV-712
