I am not sure if this is a bug.
we have 2 inverters with batteries on a single phase. we have a target of of 50% for battery charge. once 1 reaches this level and solar production exceeds the usage it sends the excess to the grid.
House 2 is just a standalone inverter.
Total solar production is 4222w
House battery is 51% and not charging. The inverter is outputting 2966w
Office battery is 41% and charging at 909w. The inverter is outputting 0W
Total house usage is 1249w
Sending to the grid 1915w
the 1915w should be going into the batteries.
