Description
xVictron MultiPlus-II 48/8000/110-100 230V Inverter Charger
The Victron MultiPlus-II 48/8000/110-100 is a combined inverter and battery charger rated at 8000VA continuous output, designed for demanding off-grid, backup and hybrid solar installations. It accepts a 48V battery bank and delivers 230V AC output, with a 110A battery charger and 100A AC transfer switch built in. Suitable for residential, commercial and industrial applications where high power capacity and reliable grid or generator interaction are required.
Key Features
- 8000VA continuous inverter output with a 16000W peak surge capacity, suitable for high-load equipment and motor starting.
- 110A multi-stage battery charger with adaptive charge algorithm, compatible with lead-acid (AGM, gel, flooded) and lithium battery chemistries.
- 100A AC transfer switch enables fast changeover between grid, generator and inverter power with minimal interruption.
- PowerControl and PowerAssist functions allow the unit to limit AC input draw and supplement it with battery power, preventing generator or grid overload.
- Built-in battery monitor tracks state of charge, allowing accurate management without a separate device.
- Supports parallel and three-phase operation: up to six units can be configured in parallel for increased capacity or in three-phase arrangements.
- Compatible with Victron VE.Bus for integration with GX devices, enabling full system monitoring and control via VRM or Cerbo GX.
- Programmable relay and configurable charge/discharge parameters via VEConfigure software.
Product Overview
The MultiPlus-II 48/8000/110-100 is built around a pure sine wave inverter stage that operates from a 48V DC battery bank. At 8000VA, it can handle large residential loads, commercial equipment or multiple circuits simultaneously. The 110A charger is not a simple bulk charger: it uses Victron's adaptive four-stage algorithm (bulk, absorption, float, storage) and can be configured for different battery chemistries and capacities through VEConfigure software.
PowerAssist is a particularly useful feature in generator or limited-grid scenarios. When AC input is available but limited (for example, a small generator or a restricted grid connection), the MultiPlus-II can draw the maximum permitted current from the source and supplement the remainder from the battery bank. This avoids tripping breakers or overloading a generator while still meeting peak load demand. PowerControl performs the complementary function of capping AC input draw to a user-defined limit.
The unit supports parallel and three-phase configurations without additional hardware beyond the units themselves and VE.Bus cabling. Up to six MultiPlus-II units can be paralleled for a maximum of 48kVA in single-phase, or arranged as a balanced three-phase system. This scalability makes it practical for larger off-grid sites, commercial backup systems and microgrid installations where load growth is anticipated.

Installation Notes
The MultiPlus-II 48/8000/110-100 operates at high DC currents from a 48V battery bank and must be installed by a qualified electrician or accredited installer. In the UK, grid-connected or grid-interactive installations must comply with G98 or G99 requirements depending on export capacity and connection type. Configuration via VEConfigure software should be carried out by a competent person familiar with Victron systems. Lithium battery installations require correct charge profile settings and, where applicable, BMS communication to be configured before commissioning. The unit's weight of 40.8 kg means appropriate lifting and mounting provisions are required during installation.
