The Victron Quattro 12/3000/120-50/50 combines an inverter and battery charger in one unit, built for off-grid, marine and backup power systems that need more than a single AC connection. It runs on a 12V battery bank, delivers 3000VA of continuous inverter output at 230V, and charges at up to 120A. Two independent 50A AC inputs let you wire shore power and a generator at the same time, with automatic transfer between them.

Key features of the Victron Quattro inverter charger

• Dual AC inputs, two separate 50A inputs allow shore power and a generator to be connected together, with automatic switching between sources.
• Inverter output, 3000VA continuous at 230V AC from a 12V battery bank.
• Battery charger, 120A multi-stage charging with an adaptive algorithm that adjusts to battery condition.
• Two AC outputs, AC-out 1 is uninterrupted, AC-out 2 can be switched off to shed non-critical loads under low battery conditions.
• PowerAssist and PowerControl, draws extra power from the battery when demand exceeds the current limit of the connected AC source, letting a smaller generator or restricted shore supply run larger loads.
• VE.Bus communication, connects to Victron GX devices and VEConfigure software for monitoring, configuration and parallel or three-phase setups.
• Programmable relay, can be set for generator start/stop, alarms or other control functions.

Applications

The dual AC input design suits boats and motorhomes where shore power and a generator both need to feed the same system without manual switching. It also works well in off-grid cabins where a generator tops up solar charging, and in backup power setups where AC-out 1 keeps critical loads running without interruption. Multiple units can be linked over VE.Bus for parallel or three-phase installations.

Installation notes

Installation should be carried out by a qualified electrician or an accredited installer, given the AC wiring and battery currents involved.
