The Victron Quattro 48/5000/70-100/100 is a 5000VA inverter charger built for off-grid, backup and hybrid power systems. Its 48V DC input pairs with dual 100A AC inputs, letting shore power and a generator connect at the same time with automatic switching between them.

Victron Quattro 48/5000/70-100/100 inverter charger

• Inverter output, 5000VA at 230V AC.
• Battery charger, 70A with adaptive charge management for lead-acid, lithium and gel batteries.
• AC inputs, two, each rated at 100A, with automatic source switching.
• AC outputs, two independent outputs; one passes through both inputs, the other disconnects when the unit is inverting.
• Communication, VE.Bus interface for parallel, split-phase and three-phase configurations and Victron GX integration.
• PowerAssist, draws extra current from the battery when the connected AC source reaches its limit, so a smaller generator or limited shore supply can still cover peak loads.

Product overview

The Quattro sits above the MultiPlus because it takes two AC inputs rather than one, switching between shore power and a generator automatically. Its transfer switch is fast enough that most sensitive equipment does not lose power during the changeover. The 70A charger uses Victron's adaptive algorithm, adjusting the charge profile as the battery bank cycles rather than applying a fixed rate.

VE.Bus connectivity allows configuration and monitoring through VictronConnect and GX devices, and multiple units can be wired in parallel or arranged for split or three-phase output.

Applications

• Off-grid residential systems needing high continuous output with generator backup.
• Marine and narrowboat installations with both shore power and a generator available.
• Motorhomes and expedition vehicles running 48V battery banks.
• Commercial and agricultural backup power installations.
