Quattro power limit when AC falls away

Good day,

Is it possible to limit the power output on a 90kW Quattro system(6X15KVA)? We lost a battery and only have 70KW of battery capacity so want to limit the output power when the grid falls away to not exceed lets say 65kW to protect the internal battery fuses.

While ESS has an inverter limit option, I don't think this works on grid loss.

Wire your 'Non-Essential' loads to the ACOut2 terminals. The relay driving that will open when there is no AC input.

ACOut1 will stay live using the inverter when ACIn (1 or 2) fails.

The only way is to make sure the consumers/users load shed.

You could automatically do it it either AC out 2 as mentioned or with node red and some smart switches. Then you can do it load based and SOC based.
