ESS MP2 random export/import

Hi everyone,

I have a weird situation happening - muti is randomly injecting and consuming from grind instead of using battery (see video below)

System is grid-tied with a Fronius on ACIN and metering done via VM. Downstream loads on ACout1 are below 1000w, nothing to solicit quick power demand bursts.

Battery monitoring done by smartshut (it’s a LiIon “dumb” battery hence the higher voltage - fully charged at 58v).

LE: if I set to inverter only grid stabilises and multi discharges as expected
