The Victron QUA122305130 is a high-power inverter/charger from the Quattro-II series, designed for 12 VDC battery systems. It delivers up to 3000 VA of pure sine wave AC power at 120/240 VAC, making it ideal for RV, marine, off-grid, or backup power applications where dual AC inputs (like shore power and a generator) are needed. The active input is automatically selected so no external transfer switch. When a 120/240 volt input is available it will pass through to the output,. When only a single leg of 120 is available at the input the inverter will output two legs of 120 volts but will not produce any 240 volt output. When inverting it will produce two legs of 120 volts but no 240 volt output.
