Victron Multi RS Solar 48/6000: Setup Guide

Key Takeaways

• The Multi RS Solar 48/6000/100-450/100 (PMR482602020) provides 230 V AC output (25 A continuous) and charges 48 V battery systems.
• Continuous output power at 25°C increases linearly from 4,600 W at 46 V to 5,200 W at 52 V, with 4,500 W at 40°C and peak power of 9 kW for 3 seconds.
• Features 2 independent MPPT trackers rated at 3,000 W each (6,000 W total), with a 65-450 V MPPT window and 120 V start-up.
• Maximum PV voltage is 450 V and cannot exceed 8 times the 25°C reference battery float voltage (e.g. max 400 V at 50 V float).
• Maximum charge current from AC is 88 A and total maximum combined charge current is 100 A.

Understanding the Victron Multi RS Solar 48/6000

The Victron Multi RS Solar 48/6000/100-450/100 (part number PMR482602020) combines a 48V pure sinewave inverter with high-voltage solar MPPT charge controllers. Housed in a steel enclosure weighing 12.3 kg, the unit is engineered for residential and off-grid energy storage systems.

The inverter stage delivers 230 V AC output with a maximum continuous inverter current of 25 A. At 25°C, continuous output power scales linearly from 4,600 W at 46 V DC to 5,200 W at 52 V DC. When ambient temperatures rise, continuous output is rated at 4,500 W at 40°C and 3,000 W at 65°C. For motor starting, the inverter delivers peak power of 9 kW for 3 seconds and 7 kW for 4 minutes. Maximum efficiency reaches 96.5% at 1 kW load and 94% at 5 kW load.

Dual MPPT PV Sizing & 8x Float Constraint

The integrated solar charger includes 2 independent MPP trackers providing 3,000 W per tracker for a total DC solar charging capacity of 6,000 W.

PV string design must satisfy the following parameters:

• Maximum DC PV Voltage: Absolute ceiling of 450 V.
• Operating Voltage Range: MPPT tracking range is 65-450 V with an initial start-up voltage of 120 V.
• Current Limits: Maximum operational PV input current is 12 A per tracker, with a maximum PV short-circuit current of 16 A.
• 8x Float Law: Maximum PV voltage must not exceed 8 times battery float voltage at 25°C. For example, if battery float voltage is set to 50 V, maximum PV string Voc must not exceed 400 V.

The solar stage features an earth leakage trip level of 30 mA and an isolation fail level of 100 kΩ checked before startup.

Battery Charger Settings & Wiring

The Multi RS Solar charges 48 V battery banks across a programmable voltage range of 36 V to 60 V:

• Default Absorption Voltage: 57.6 V (adjustable at 25°C).
• Default Float Voltage: 55.2 V (adjustable at 25°C).
• Charging Current: Maximum charge current from AC sources is 88 A, and total combined charging current reaches 100 A.
• Connections: Battery bank connection uses heavy-duty M8 bolts. The pass-through transfer switch is rated at 50 A AC.

Communications & Safety Standards

System monitoring and configuration are supported via:

• VE.Can Port: Direct connection to Cerbo GX and Ekrano GX supervisory controllers.
• VE.Direct Port: Dedicated connection for accessories such as GlobalLink 520.
• Bluetooth: Integrated wireless commissioning via the VictronConnect mobile application.
• Compliance: Safety certification complies with EN-IEC 62109-1, EN-IEC 62109-2, EN-IEC 60335-1, EN-IEC 60335-2-29, IEC 62040, and IEC 62477.
