Victron Energy MultiPlus-II 12/3000/120-32 menič/nabíjačka

The Victron Energy MultiPlus-II 12/3000/120-32 is a powerful and versatile inverter/charger designed for professional marine, mobile, and off-grid applications. Combining a 3000VA pure sine wave inverter, a 120A adaptive battery charger, and a high-speed 32A AC transfer switch, it delivers reliable AC power from a 12V battery bank while intelligently managing shore power or generator input. The MultiPlus-II features PowerAssist technology, which prevents overload of a limited AC source by supplementing with battery power, and supports parallel and three-phase operation for scalable system configurations.

Advantages

With its compact design, high efficiency (up to 94%), and advanced features like VE.Bus communication and remote monitoring capability, the MultiPlus-II offers unmatched flexibility and reliability. The adaptive 4-stage charge algorithm optimizes battery life, while the PowerAssist and programmable relay provide intelligent energy management. Ideal for RVs, boats, and off-grid homes, this unit ensures seamless power transition and robust performance in demanding environments.
