The Victron Quattron 48/15000/200-100/100 is a 15kVA inverter charger built for off-grid, backup and hybrid power systems. It runs from a 48V DC battery bank and outputs 230V AC, with two independent AC inputs so a generator and grid or shore supply can both be connected. The QUA483150000 model targets large residential, commercial and marine installations where continuous power and automatic source transfer matter.

Victron Quattro 15kVA key features

• Inverter output, 15,000VA (15kVA) continuous at 230V AC, 50Hz, from 48V DC.
• Dual AC inputs, two independent AC sources, such as generator and grid, with automatic selection and transfer.
• Battery charger, 200A with an adaptive algorithm for flooded, gel, AGM and lithium batteries.
• AC pass-through, two independent 100A outputs for load management and critical load separation.
• VE.Bus communication, integrates with Victron GX devices for remote monitoring, parallel operation and multi-phase setups.
• PowerControl and PowerAssist, limits generator or shore power draw and draws on the battery when demand exceeds available AC current.

System integration

Up to six units can be combined for higher power output or three-phase configurations. Programmable relay outputs handle generator start/stop control and other system logic. Connected to a Victron GX device, the Quattro reports status and metering data to the VRM portal, and multiple units can be managed together through VEConfigure software.

Applications

• Large off-grid residential or farm installations needing high continuous AC power from a 48V battery bank.
• Backup systems combining grid and generator supply with automatic transfer.
• Marine and shore power setups using dual AC input for generator and shore supply.
• Commercial sites running multiple units in parallel or three-phase configuration for scalable power.
