Specifications
Product Description
The Victron MultiPlus-II 48V 5000VA 48/5000/70-50 is designed for 48 V installations that require higher continuous power and faster battery recovery times. It offers 5000 VA (≈4000 W) output at 230 V with pure sine wave, automatic 50 A transfer switch, and PowerControl/PowerAssist management, which adds inverter power to grid or generator power to prevent overloads and maintain system stability. Its ESS compatibility allows prioritization of photovoltaic energy and batteries, optimizing self-consumption and ensuring reliable backup during outages.
Main Features
- Continuous power 5000 VA (≈4000 W) with peak power up to ≈9000 W.
- Automatic transfer 50 A with “no-break” time (<20 ms) for critical loads.
- Battery charger of up to 70 A with adjustable profiles and temperature sensor.
- ESS integration: flow control with external meter/sensor and self-consumption strategy.
- Professional scalability: up to 6 units in parallel and possibility of three-phase systems.
- Complete connectivity: VE.Bus, local control (VictronConnect) and remote (GX devices + VRM portal).
Advantages or Benefits
- Reliable starting of demanding loads (pumps, compressors, air conditioning) thanks to high peak power.
- Fewer generator hours: the 70 A charger accelerates battery bank recovery.
- Guaranteed continuity: the “no-break” mode prevents blackouts in sensitive electronics.
- Safe and flexible installation: electronic protections, programmable relay, and wide compatibility.
- Long-term investment: expandable platform that grows with your project without redoing the installation.
Purpose or Applications
Ideal for off-grid homes with high demand at 48 V, microgrids with backup generator, residential/commercial ESS systems, boats, and professional vehicles requiring stable 230 V and high peaks.
