Can Multiplus II (5000VA) know if the energy is coming from grid or genset?
I mean, during grid blackout, the feed goes to critical loads, energy taken from batteries.
When the capacity from batteries goes low, Cerbo will set the genset on.
This leads to problem, because the mains (Ac out 2) becomes active as the AC in feed gets electricity into the unit. The mains load exceeds the capacity of the genset. The genset is only for critical loads.
So, my question is, can Cerbo or the energy meter hold the relay open on AC out 2 when the feed is from genset? And close the relay when the feed is from grid?
