Victron Quattro-II 2x120V Inverter Charger Description
Similar to the MultiPlus-II 2x120V, the Quattro-II 2x120V is a combined inverter and charger specifically designed for standard North American 50A 120/240VAC split-phase applications. Additionally, it can accept two AC inputs and automatically connects to the active source.
Whether it is supplied from shore power or a generator, the Quattro-II 2x120V can accept and pass through both lines of a 120/240V supply, with the capability to utilise 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 no AC sources are 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 a 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 our versatile inverter/charger range, including PowerControl, PowerAssist, Input Current Limit, two AC outputs, as well as parallel and 3-phase configuration for larger capacity VE.Bus systems. Suitable for LiFePO4 batteries and a variety of other battery technologies.
