Victron Energy MultiPlus-II 48V 5000VA 4000W Inverter Charger 120V 70A 95A Transfer Switch VE.Bus

Victron Energy MultiPlus-II 48V 5000VA 4000W Inverter Charger 120V 70A VE.Bus

The Victron Energy MultiPlus-II 48V 5000VA Inverter Charger combines a pure sine wave inverter, high-performance battery charger, and advanced AC transfer switch into one powerful energy management solution. Designed for off-grid, backup power, RV, marine, and solar energy storage systems, the MultiPlus-II delivers reliable 120V AC power while intelligently managing battery charging and shore or generator input.

Featuring PowerAssist and PowerControl technology, the MultiPlus-II automatically supplements limited shore power or generator capacity with battery power during peak demand while preventing overloads. Once demand decreases, surplus power is redirected to recharge your battery bank.

The integrated 95A transfer switch provides seamless power transfer in less than 20 milliseconds, ensuring uninterrupted operation of sensitive electronics, computers, networking equipment, and essential appliances during utility or generator outages.

Designed for complete energy independence, the MultiPlus-II works seamlessly with Victron MPPT solar charge controllers, lithium batteries, and Energy Storage Systems (ESS). It supports parallel, split-phase, and three-phase configurations, allowing your system to grow as power requirements increase.
