MultiPlus II 48V 5000 VA 70A-50A

Victron Energy MultiPlus-II 48/5000/70-50 is an advanced, multi-functional voltage converter and charger that provides maximum efficiency and wide functionality in a variety of environments. With a built-in sine wave inverter, adaptive charging technology and fast switch-over to emergency power supply (UPS), this device is the ideal solution for powering systems in homes, boats or vehicles. Its total power of 5000 VA and maximum charging current of 70 A make the MultiPlus-II suitable for the most demanding installations, offering stable and reliable power at all times.

Key Benefits of MultiPlus-II

PowerControl and PowerAssist functions

The MultiPlus-II features advanced features Power Control and PowerAssist, which automatically adjust charger operation to prevent overloading the power source. PowerAssist in particular, it allows the compensation of the lack of energy by using the energy from the battery, which helps to avoid overloading the installation, especially when using limited power sources such as generators. These functions make the device ideal for use in environments where variable loads are a challenge.

Remote monitoring and control

Thanks to device compatibility GXsuch as Cerbo GX, it is possible to fully monitor and remotely control the system from anywhere in the world. Application VRM and the VRM web portal allow users to easily access current device performance data, allowing for quick response if problems occur or settings need to be changed.

Energy Storage Systems (ESS) Flexibility

One of the most important applications of the MultiPlus-II is its ability to work in energy storage systems (ESS). The device can be easily integrated with solar chargers MPPT or inverters Grid-tie PV, which allows for efficient management of solar energy. This function allows you to minimize the consumption of energy from the grid while maximizing the use of renewable energy, which is invaluable in the context of the increasing importance of green technologies.

Uninterruptible Power Supply (UPS)

MultiPlus-II offers the function UPS, which automatically switches the system to emergency power in the event of a mains failure. The transfer process takes less than 20 milliseconds, ensuring that even the most sensitive devices, such as computers and IT systems, will continue to operate without disruption. This feature is essential in places where power reliability is a priority.

Compact design and easy installation

The MultiPlus-II housing has been designed with compactness in mind, making it easy to install even in confined spaces. Despite its relatively small size, the device offers the full functionality of larger systems, making it ideal for campers, boats and industrial installations with limited technical space.

Key Features of the MultiPlus-II

• Remote monitoring and control: Ability to monitor the device using the VRM app and the VRM web portal, both locally and remotely via the internet.
• PowerAssist: Prevents power sources from becoming overloaded by adding power from the battery when the load exceeds available resources.
• UPS function: Fast switchover to emergency power in less than 20 ms, ensuring continuous operation of connected devices.
• Working in ESS systems: Optimal energy management in energy storage systems using MPPT solar chargers or Grid-tie PV inverters.
• Parallel and three-phase operation: Up to six devices can be connected together for higher output power or three-phase operation.
