The Victron MultiPlus-II 48/3000 - 35-50 - 120V - UL Approved is an all-in-one inverter/charger that unifies Victron's MultiPlus and MultiGrid technologies in a compact package for backup power, off-grid living, marine, and RV installations.
-
All-in-one inverter/charger: Combines power conversion, charging, and grid-tie capabilities in a single compact unit for streamlined power management.
-
UPS with 20 ms transfer: In the event of grid, shore, or generator loss, the inverter automatically takes over in under 20 milliseconds to keep critical loads running.
-
PowerControl & PowerAssist: External current transformer option enables precise external current sensing (max 32 A) to maximize energy self-sufficiency.
-
ESS-ready: Core component of Victron Energy Storage Systems (ESS), capable of pairing with MPPT solar chargers or grid-tie PV inverters for flexible solar and storage integration.
-
Anti-islanding & approvals: Built-in anti-islanding protection with an extensive list of country approvals for safe, compliant grid connection.
-
Remote Monitoring & Control: When paired with a Cerbo GX, monitor and control locally via LAN or remotely from anywhere in the world using the free VRM app and VRM portal.
-
