Victron MultiPlus-II 3kVA 12V Inverter Charger

The Victron MultiPlus-II 3kVA 12V Inverter Charger is a high-performance, all-in-one hybrid power solution designed for residential, commercial, and off-grid energy systems requiring a 12V battery setup. Combining a pure sine wave inverter, a high-efficiency battery charger, and advanced grid management features, it ensures reliable, uninterrupted electricity for a wide range of applications.

With a 3kVA output (≈2.4kW at 0.8 power factor), this inverter charger can efficiently power lighting, computers, televisions, pumps, refrigeration, security systems, and small office equipment. The 12V configuration is ideal for smaller battery banks, RVs, boats, cabins, or off-grid residential systems where lower voltage is required.

The MultiPlus-II 3kVA features PowerAssist technology, which intelligently supplements limited grid or generator power with battery energy during peak demand. This prevents overloads and avoids nuisance trips while allowing higher loads to run without upgrading grid or generator capacity.

As a true UPS (Uninterruptible Power Supply), the inverter switches to battery power within milliseconds during grid failure, ensuring sensitive electronics remain protected and operational. Its integrated adaptive battery charger supports a wide range of battery chemistries including lithium-ion (LiFePO₄), AGM, GEL, and flooded lead-acid batteries, optimizing charge profiles and extending battery life.

For advanced system control, the MultiPlus-II is compatible with Victron GX devices and the VRM portal, providing remote monitoring, diagnostics, and configuration from anywhere in the world. This feature makes it especially useful for installations in remote or unmanned locations.

The inverter supports parallel operation and three-phase configurations, allowing users to scale their system as power requirements grow. Built to industrial-grade standards, it features robust thermal management, overload protection, short-circuit safeguards, and intelligent safety mechanisms for reliable and long-lasting operation.

In summary, the Victron MultiPlus-II 3kVA 12V Inverter Charger is a compact, scalable, and professional-grade hybrid inverter, perfect for users seeking reliable backup power, hybrid solar integration, and advanced monitoring in a 12V system.
