Okay, but I do not like that arrangement for cross strapping subpanel L1 & L2 when off-grid unless there is a time delay on cross-strapping after grid drops. Any loads on L2 side gets hit with a phase reversal.
If you have a refrig or AC compressor powered on L2 side and grid goes out, compressor gets hit with a 180 degree phase reversal that causes high surge current unless there is a long dead time delay.
