Victron Energy Multi RS Solar 48/6000/100-450/1006kVA 48V single-phase hybrid inverter/charger with two 450V MPPT trackers

Overview

The Multi RS Solar 48/6000/100-450/100 combines a 48V inverter/charger with two isolated MPPT trackers of 3kW each, for 6kW of PV conversion from strings of up to 450V. It delivers 4600–5200W continuously at 25°C, 9kW peak for 3 seconds, and charges the battery with up to 100A from sun and grid combined. Grid-code certificates such as EN 50549, VDE-AR-N 4105, C10/11 and TOR Erzeuger Typ A are published for it. It suits single-phase homes and small businesses, or three-phase sites with three units, and weighs 12.3kg.

• 48V 6kVA inverter/charger, 230V 50Hz

• Up to 100A battery charging (AC + PV)
• 50A transfer switch with PowerControl and PowerAssist
• Three-phase with one unit per phase; no parallel
• Display, Bluetooth, VE.Can and VE.Direct ports

How it works

The Multi RS is a lightweight high-frequency inverter/charger for 48V batteries. It inverts 4600–5200W continuously at 25°C (depending on battery voltage), 4500W at 40°C and 3000W at 65°C, with 9kW for 3 seconds and 7kW for 4 minutes. The 50A transfer switch passes grid or generator power to the loads; PowerControl limits the input current, and PowerAssist adds battery power when demand exceeds the supply. AC-out-2 is wired directly to the input for non-critical loads such as a boiler.

The Solar versions add two independent, galvanically isolated MPPT trackers of 3kW each (450V max., 120V start-up, 12A per tracker). Total battery charging is limited to 100A from AC plus PV, and up to 88A from AC alone at 230V. The unit can also run as a PV inverter without a battery. Operating modes listed by Victron are hybrid, backup, off-grid and generator mode.

Versions

The Multi RS Solar is a wall-mounted unit of 425×462×127mm and 12.3kg with M8 battery bolts. The Multi RS19 Solar has the same electronics in a 19-inch rack enclosure (133mm high, 12.2kg) with Amphenol SurLok Plus battery connectors, an extra BMS-Can port and IP20 protection, so it can sit in the same cabinet as rack batteries. The Multi RS 48/6000/100-50 has no solar trackers (11.2kg): PV is added with separate MPPT solar chargers or AC-coupled PV inverters.

Installation and compatibility

Wall units must hang upright with 30cm clearance above and below; the RS19 is installed horizontally in a rack with 1U free above and below. Victron's minimum battery is 200Ah lead-acid or 100Ah lithium, with a 125A DC fuse on 35mm² cable (200A on 70mm²).

AC input and output each need a breaker of 50A or less; only TN and TT earthing systems are supported. Victron lithium batteries need a Lynx Smart BMS NG or smallBMS NG; other CAN-bus lithium batteries connect to the BMS-Can port of a GX device. Three units can form a three-phase system; parallel units are not supported.

Monitoring and settings

All settings are made in the VictronConnect app over Bluetooth, or via USB with a VE.Direct interface; VE.Configure assistants are not supported and the units do not join VE.Smart Networks. A GX device such as the Cerbo GX connects through VE.Can for VRM monitoring, ESS functions such as zero feed-in, and remote firmware updates. The VM-3P75CT energy meter is connected via VE.Can or Ethernet. AC-coupled PV inverters on the output are regulated by frequency shifting when the grid is absent. A programmable relay can start a generator.
