Victron MultiPlus-II 48/8000/110-100/100 Inverter

The Victron MultiPlus-II 48/8000/110-100/100 230V is a premier, industrial-grade hybrid inverter/charger engineered specifically for high-demand residential, commercial, and professional off-grid or grid-tied Energy Storage Systems (ESS). Combining the proven reliability of the legendary MultiPlus range with advanced grid-compliance and power-optimisation technologies, this heavy-duty 48V unit serves as a highly efficient pure sine wave inverter, a sophisticated 110A adaptive battery charger, and a high-speed 100A automatic changeover switch integrated into a durable steel enclosure.

True Uninterrupted Power Supply (UPS) Functionality

Equipped with an intelligent dual AC output architecture, the MultiPlus-II ensures continuous power delivery to critical infrastructure during load-shedding, grid failures, or generator dropouts. The primary AC output operates with a true no-break, high-speed transfer capability. When the main power source is lost, the internal pure sine wave inverter assumes the load in less than 20 milliseconds—a speed so rapid that computers, servers, and sensitive appliances continue operating without interruption or data loss. The secondary AC output is specifically designed to isolate heavy-draw, non-essential loads (such as water heaters or air conditioning units), preventing accidental battery depletion when running solely on stored energy.

Intelligent PowerControl and PowerAssist Capability

Managing constrained power sources like generators, shore supplies, or limited grid connections is seamless thanks to Victron's proprietary management algorithms:

• PowerControl: The MultiPlus-II continuously monitors overall AC power consumption and dynamically throttles the battery charging current when it detects an impending overload, prioritising your active operational appliances.
• PowerAssist: Takes power optimisation further by instantly injecting supplementary power from the 48V battery bank when peak demands exceed the maximum current limits of your generator or grid connection. Once the peak load drops, any available surplus capacity is immediately redirected to replenish the batteries.

Seamless Solar Integration and Flexible Scaling

Optimised to serve as the core conductor of modern solar energy systems, the MultiPlus-II natively accommodates both DC-coupled MPPT solar charge controllers and AC-coupled grid-tied solar inverters. For scalable commercial arrays or complex power demands, up to three identical units can be configured together for full three-phase operation, or paired with a dedicated GX management device (such as the Cerbo GX) to unlock advanced multi-inverter system configurations.

Robust Protection and Complete Monitoring Integration

The integrated battery charger features a highly efficient, 4-stage adaptive algorithm (Bulk, Absorption, Float, and Storage) capable of delivering a powerful 110A charge current. It integrates perfectly with premium lithium (LiFePO4) battery setups via managed CAN-bus interfaces, as well as traditional lead-acid chemistries. Housed in an IP21-rated steel enclosure, it features extensive electronic safeguards against output short circuits, thermal over-temperature, overloading, and extreme battery voltage conditions. System programming and live diagnostics are easily managed via VEConfigure software or scaled to the cloud using a GX device to unlock free remote management through the global Victron Remote Management (VRM) portal.
