Quattro-II 12/3000/120-50 2x120V

NOTE: This is the 12v version of the Quattro-II 2x120V, which is ideal for RVs with 50A shore-power inlet plus onboard generator.

The Quattro-II 12/3000/120-50 2x120V is the perfect one-box mobile solution for standard North American 50A 120/240VAC split-phase applications. Whether it is supplied from shore power or a generator, the Quattro-II 2x120V can accept and passthrough both lines of a 120/240V supply, with the capability to utilize the full 50A for charging and AC loads. When connecting to a single phase 120V supply, the L1 input of the Quattro-II 2x120V will accept incoming power for charging and passthrough, while combining the L1 and L2 outputs for single-phase 120V on each line.

The Quattro switches to inverter operation when neither AC source is available. The inverter output is also 120V single phase. In inverter mode, the Quattro-II 2x120V internally connects both lines L1 and L2 together to provide 120VAC to loads on either output. Therefore, in all connection circumstances, both sides of an RV distribution panel will be supplied with 120V. However, 240VAC is only available when the Quattro is supplied by a split phase 120/240VAC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.

The Quattro-II 2x 120V has all of the expected features of Victron's versatile inverter/charger range, including PowerControl, PowerAssist, Input Current Limit, two AC inputs,  two AC outputs, as well as parallel and 3ph configuration for larger capacity VE.Bus systems. Suitable for LiFePO4 batteries and a variety of other battery technologies.
