3 Phase Quattro setup. Grid metering set to Inverter/Charger, as all loads on AC1 + AC2 out. ESS working nicely except that it seems to constantly pull from the grid what looks like rough idle load of the quattros (which is about 120w x3 = 360). Grid setpoint is 10w.
Even if loads go up to say 10kw, the quattro will still pull roughly this figure from the grid. If I kill grid battery takes whole load fine with seamless changeover.
Could it be that the idle load is not included in the Grid Metering calculation somehow? Wondering if there is a downside to setting grid setpoint to -360 to try and offset it
Appreciate any thoughts
