As far as I know, it's not possible in a installation with parallel units to have slave units automatically shut down or stand-by in low load situations.
For a off-grid system, there is fairly high load, around 12-16kVa/Phase for 3-4 hours a day. The system would be 3x (8kVa*3) or 3x (10kVa*2). The other hours there is a fairly low load of 1-2kVa/phase. To reduce standby losses it would be great if it would be possible to shutdown the non used inverters.
