The Victron MultiPlus-II 48/3000/35-32 230V GX pairs a 3000VA inverter charger with a built-in GX device, aimed at 48V battery systems running on 230V AC. Inverter, charger and system monitoring sit inside one enclosure, which suits off-grid setups, backup power arrangements and solar self-consumption systems that would otherwise need a separate GX controller.

Inverter with battery charger built around a 48V system

• Inverter output: 3000VA / 2400W continuous at 230V AC from a 48V DC bank.
• Battery charger: 35A output with an adaptive charge algorithm.
• AC input limit: 32A, adjustable through the GX interface or external control.
• Integrated GX device: onboard monitoring, data logging and VRM portal access without extra hardware.
• Transfer switch: typically 20ms, suited to UPS-sensitive loads.
• Weight: 18.83 kg.

PowerControl, PowerAssist and DVCC

PowerControl and PowerAssist limit AC input draw and top up demand peaks from the battery, which stops a generator or a limited shore supply from tripping out. The unit works with Victron DVCC for managed battery systems, including lithium, letting the GX device coordinate charge and discharge limits directly with the battery's own management system.

ESS and grid-tied use

ESS configuration lets the MultiPlus-II GX run in a grid-connected setup, managing solar self-consumption and switching to backup power during an outage. UK grid-tied installations need to meet G98 or G99 requirements depending on export capacity and the local DNO. Installation should be carried out by a suitably qualified electrician.

Applications

• Off-grid residential and commercial systems built around 48V battery banks
• Solar self-consumption with battery storage in ESS configuration
• Backup power and UPS applications for sensitive loads
• Marine and vehicle installations needing 230V AC from a 48V DC supply
• Generator-backed systems where PowerControl manages a limited AC input
