Quattro-II 12vDC/3kVA 2x120

Similar to the MultiPlus-II 2x120, this Quattro-II 2x120 12vDC/3kVA unit 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 2x120 can accept and pass through both lines of a 120/240 supply, with the capability to utilise the full 50A for charging and AC loads. When connecting to a single-phase 120vAC supply, the L1 input of the Quattro-II 2x120 will accept incoming power for charging and passthrough while combining the L1 and L2 outputs for single-phase 120vAC on each line.

The Quattro switches to inverter operation when no AC sources are available. The inverter output is also 120vAC single-phase. In inverter mode, the Quattro-II 2x120 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 120vAC. 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 240vAC air conditioners from discharging the battery.

The Quattro-II 2x 120 has all of the usual features of Victron's 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 (may require programming using MK3-USB Interface to achieve appropriate compatibility).
