I have Multiplus 3000/12/120, BMV-712, and Cerbo.
My batteries are slightly undersized given the full current capability of the Multiplus. They can produce 200A continuous and 400A for a few seconds.
One option is to simply limit AC use, and monitor the current being drawn from the batteries.
What automated options are there? Can the Multiplus be programmed to limit the current draw? Can BMV or Cerbo be programmed to alarm when current is over a set value? Any other ideas or recommendations?
