Introduction
The MultiPlus-II series forms the foundation of modern Victron Energy power systems. It combines inverter and charger functions, ensuring reliable energy management in residential, commercial, and off-grid applications.
Key Features
Intelligence, efficiency, control, reliability
Power Assist
MultiPlus-II automatically prevents overloading of power sources such as the grid or a generator. It first limits battery charging current and, if necessary, supplements power from the batteries to maintain stable supply without overloading the system.
UPS Backup Power
In case of a power outage, MultiPlus-II instantly switches to battery power, ensuring uninterrupted operation of connected devices. The switch occurs in less than 20 milliseconds, keeping even sensitive electronics running without interruption.
ESS
MultiPlus-II is a key component of the Victron ESS system, enabling flexible connection with MPPT solar chargers and Grid-tie PV inverters for smart energy management and optimal use of renewable sources.
Applications
A universal solution for various industries
Home and photovoltaic installations
Provides full integration with energy storage and solar chargers, increasing self-consumption of PV energy.
Off-grid and mobile systems
Ideal for powering locations without grid access – summer houses, RVs, and boats.
Emergency power for businesses and critical facilities
Ensures uninterrupted operation during power failures, protecting IT equipment and security systems.
Why MultiPlus-II?
Because it is one of the most versatile and reliable solutions in energy management. MultiPlus-II means stability, safety, and energy independence in one device, designed to operate reliably for years in any power configuration.
Monitoring and Control
Full system control
Remote access to the system anytime
When MultiPlus-II is connected to a GX device such as Cerbo GX or Ekrano GX, users gain full access to monitoring and configuration of the entire installation. The system can be managed locally via LAN or remotely over the Internet using the free Victron VRM app or VRM Online portal.
