With a battery-backed Xantrex XW system on the grid, the output of the system typically goes to a sub-panel that you want backed up in case the grid goes down.
The breakers in the XW distribution box are 60A, but the maximum size breaker I can put on the grid 200A service panel is 40A (due to NEC 120% backfeed rule).
Something doesn't seem right about this. At night, with the grid on and inverter off, it means I'm actually limited to 40A at the sub-panel. (I don't want the inverter supplementing any part of the load from batteries as long as the grid is available.)
Is there another way to do this? Meter load-side tap?
