Strange behaviour ESS when in ON mode in combination with "optimized with battery life)

Hi,

I have a 3 fase multiplus II 5Kv ESS configuration.

The most strangest thing is happening on this new config. For some reason the ESS system is pumping arround current on the grid (minus on fase 1 and positive on fase 2 and 3)


See image.

There is only load connected to output 1 (Critical load) but for some reason a lot of current is pumped arround between fase 1 and between fase 2 and 3, trying to keep the cumulative of the fases at zero. But.... There is just a little load on output 1.

What also happens is that the Critial load is rising about 200W when i change the ESS mode from "Inverter only" to "On".

Also the pumping arround of current is having a big load on the Multiplus connected to fase 1 and is getting quite hot after a while and therefore makes a lot of noise.

I really like to understand why this is happening and hope i can solve the issue!
