The Victron Multi RS 48/6000/100-50 is a 6000VA inverter charger built for 48V battery systems running at 230V AC. It combines a high-frequency inverter, a 100A battery charger and a 50A MPPT solar charge controller in one enclosure, cutting the wiring and cabinet space needed for off-grid and hybrid solar setups.

Key features of the Victron Multi RS

• Inverter output, 6000VA at 230V AC from a 48V DC battery bank.
• Battery charger, integrated 100A multi-stage charger with adaptive charge algorithm.
• Solar charging, built-in 50A MPPT controller for direct PV array connection.
• Weight, 12.5kg thanks to the high-frequency design, lighter than transformer-based equivalents.
• System integration, VE.Bus compatible for monitoring and remote configuration via GX devices.
• PowerAssist, the unit can supplement grid or generator input when demand exceeds the AC source capacity.
• Configuration, set up via the VictronConnect app over Bluetooth or through the VE.Bus interface.

How the three functions work together

The Multi RS replaces separate inverter, charger and MPPT hardware with one unit. The 48V nominal battery voltage suits larger off-grid and hybrid systems, where higher voltage reduces current and cable losses. The 100A charger output can bring a large battery bank back up efficiently from a generator or grid supply, while the 50A MPPT input takes PV arrays directly and feeds solar harvest into the battery bank alongside or independently of the AC charger.

VE.Bus support means the Multi RS sits fully inside a Victron system alongside GX monitoring devices, Venus OS and the VRM portal. Charge profiles and transfer thresholds can be set remotely once commissioned.

Applications

• Off-grid residential and commercial installations with solar PV and battery storage.
• Hybrid solar systems needing grid or generator backup alongside solar generation.
• Remote sites, agricultural buildings and cabins needing a self-contained power system.
• Marine and vehicle applications using 48V battery banks with 230V AC output.
• Backup power for critical loads where fast transfer from grid to battery matters.

Installation notes

Fit the Multi RS 48/6000/100-50 with a qualified electrician or MCS-accredited installer. It operates at 48V DC with high current battery connections and connects to 230V AC mains or generator supply. Grid-connected UK installations must meet G98 or G99 requirements as applicable. PV and battery cabling should be sized for the current ratings of the integrated charger and MPPT inputs, and configuration via VE.Bus or VictronConnect should be completed before commissioning so charge parameters match the connected battery chemistry.
