Hi,
9.6 per leg?

50 amp connector for continuous duty is limited to 9.6 kW by NEC
Theoretically, if you can max out both legs, you've got 12kw. But reality is you can't continuously draw 50amps on both legs and the specs don't allow for it.
Even the 9.6kw, if pretty optimistic. If it's hot out and both air/con units are running along with other stuff, you can easily lose 1/3-1/2 of that to house loads. Then the charging is not 100% efficient so the amount that winds up in the batteries is even less.
Realistically, figure maybe 4kwh/h going into the batteries or approx 100kwh per day. Someone suggested it was a 660kwh battery bank, so figure almost a week to charge on 50amp. If you only have 30amp, it might be a couple weeks to charge or longer as the house loads will eat up a greater percentage of a 30amp supply (which is more like 25amp for continuous).
