"12,000W
Split Phase: 240v @ 50A (or 120v @ 50A from both L1-N and L2-N)
Single Phase: not supported.
(The transformer can physically do 120v
single-phase, but none of the AC output circuitry is rated for 100A)NOTE: Inverter alarms are based on amperage, not wattage"
OK, how much 120V single phase current CAN it do?
Oh, I think it means 50A on L1, 50A on L2, 50A on N.
Surge wattage may be available at 120V (double current), but steady state 6000W not 12000W on one phase.

Transfer Efficiency | 99% (yeah, the competition always lists this useless spec!) |
AC Charge Efficiency | ~72% (wonder why the competition never lists this!) |
Maximum Charge Current | approx. 120A @ 48v |
"
120A x 48V x (1 - 72%) = 1612W dissipated by inverter when charging?
72% is more like expected round-trip efficiency with lead-acid battery.
