PRODUCT DESCRIPTION
The Victron Energy MultiPlus-II 48V 5000VA 120V UL1741 Certified Inverter Charger (Model 48/5000/70-95, MPN PMP482505120) combines a 5000VA pure sine wave inverter, a 70A adaptive battery charger, and an ultra-fast UPS transfer switch in one compact, intelligent unit. Built for off-grid, hybrid solar, home backup, marine, RV, and commercial energy systems, this UL1741 certified 48 volt inverter charger meets North American grid-connection requirements with integrated anti-islanding protection.
UL1741 Certified for Grid-Connected Energy Storage
UL1741 certification makes the MultiPlus-II well suited for North American grid-tied solar and energy storage systems. Integrated anti-islanding protection supports safe grid-connected installations, while ESS and Dynamic ESS compatibility enable advanced self-consumption energy management.
48V 5000VA Pure Sine Wave Inverter with 70A Charger
The 5000VA inverter delivers clean, stable 120VAC power for electronics, appliances, tools, and critical equipment. The 70A adaptive multi-stage charger maximizes performance and extends battery life for large lithium and lead-acid battery banks.
PowerAssist and PowerControl for Generators and Shore Power
PowerControl intelligently manages incoming AC power to protect connected sources. When demand exceeds limited shore power or generator capacity, PowerAssist supplements it with battery power to help prevent overloads and breaker trips.
Ultra-Fast UPS Backup Power
During an outage, the MultiPlus-II transfers to inverter power in less than 20 milliseconds, keeping computers, networking equipment, and other sensitive electronics running.
Remote Monitoring and Expandable Design
Paired with a compatible Victron GX device, the MultiPlus-II supports remote monitoring, system management, firmware updates, and generator automation through the Victron Remote Management (VRM) platform. Multiple units can be connected in parallel or configured for three-phase operation as your system grows.
