Victron MultiPlus-II 48/6k5/100-50 Inverter

The Victron MultiPlus-II 48/6k5/100-50 230V represents the ultimate evolution in smart power management, seamlessly uniting the functionalities of the legendary MultiPlus and MultiGrid ranges. Engineered specifically for complex residential, commercial, or professional off-grid, backup, and hybrid solar Energy Storage Systems (ESS), this robust 48V unit provides unmatched reliability and performance. It functions as a pure sine wave inverter, an adaptive multi-stage battery charger, and an ultra-fast changeover switch in a single, space-saving metal housing.

Uninterrupted Power Supply (UPS Function)

Equipped with dual AC outputs, the MultiPlus-II ensures your critical infrastructure remains running. In the event of a grid failure, load-shedding, or generator disconnection, the internal pure sine wave inverter takes over the AC supply in less than 20 milliseconds. This ultra-fast transfer guarantees that sensitive electronic equipment, such as computers, servers, and communication networks, continue operating smoothly without any disruption or rebooting. The secondary AC output is configured to disconnect when running purely on battery power, safeguarding your storage against high-draw, non-essential loads like water heaters or air conditioners.

Advanced PowerControl and PowerAssist

Preventing an overload on a limited AC source—such as a generator, shore connection, or a restricted grid supply—is simple with Victron's proprietary management tech:

• PowerControl: The system automatically monitors total AC consumption and throttles battery charging when it senses an impending overload, prioritizing the operational loads.
• PowerAssist: Takes power management a step further. When peak power demand outstrips the maximum current available from the grid or generator, the MultiPlus-II instantly supplements the shortfall with power drawn from the 48V battery bank. Once the peak load drops, the excess capacity is redirected to recharge the batteries.

Seamless Solar Integration and Scalability

Whether you are constructing an off-grid installation or a grid-tied interactive hybrid system, the MultiPlus-II is fully optimized to serve as the core component. It integrates natively with both DC-coupled MPPT solar charge controllers and AC-coupled grid-tie PV inverters. For projects with expanding power demands, the unit offers exceptional scalability; up to six identical units can be wired in parallel to achieve higher continuous output, or configured for split-phase and full three-phase operation.

Intelligent Battery Care and Thermal Management

The integrated battery charger features an advanced, 4-stage adaptive charging algorithm (Bulk, Absorption, Float, and Storage) that delivers a powerful 100A charge current. It is compatible with premium lithium (LiFePO4) battery banks via managed CAN-bus interfaces, as well as traditional lead-acid chemistries. Designed for longevity, the unit utilizes active fan-assisted cooling and boasts electronic protections against output short-circuits, overloading, high or low battery voltages, and over-temperature situations.
