I have a 5kVA Quattro, running ESS. AC1 in is Grid, AC2 in is Generator.
My challenge is that in the event of a grid failure and if my batteries are low and my generator is running, it does not charge my batteries (or shall I rather say it limits current drawn from the generator to around 8A). AC is synced. Current limit on AC2 is set to 15A.
If I do increase required output power, it draws the additional power from the generator until it reaches the 15A mark. So my issue is the fact that it does not use available generator power to charge my batteries.
This use to work. No idea why it stopped
