Victron MultiPlus-II 48/5000/70-50 230V 5000W inverter 70A charger all-in-one

The Multiplus-II 48/5000/70-50 is a high-end system from Victron Energy (MPN: PMP482505012) that combines classic Multiplus components with an external current sensor and an integrated anti-islanding function. This extends the PowerControl and PowerAssist functions to 100 A and broadens the potential range of applications to include energy storage system (ESS) applications. The inverter module delivers a full 5000 W under non-linear loads, or 4000 W under continuous linear loads. The 48 V battery charger is also very well-proportioned with a 70 A charging capacity and is complemented by a 50 A transfer switch that allows for lightning-fast switching back and forth between the AC connections.

Key Features of the Multiplus-II 48/5000/70-50

• PowerControl and PowerAssist – Boosting grid or generator power
• Built-in anti-islanding function and connection option for an external current sensor (optional)
• Can be used as a backup device in grid-connected systems to provide power during grid outages
• Suitable for various ESS (Energy Storage System) applications
• Ideally suited for professional maritime applications, yachts, vehicles, and land-based, off-grid applications
• VE.Bus interface for parallel and three-phase operation, remote monitoring, and system integration
• Virtually unlimited power output through parallel and three-phase operation
• Can be configured on-site or remotely using VEConfigure software*

PowerControl and PowerAssist

On the MultiPlus-II 48/5000/70-50, a maximum grid or generator current can be set. The MultiPlus-II then takes into account other connected AC loads and uses only the “remaining” current to charge the battery. This prevents the generator or grid connection from being overloaded (PowerControl function). The PowerAssist function takes the PowerControl principle to a new level. Load peaks often occur only for a limited period of time. In such cases, the MultiPlus-II immediately compensates for insufficient generator, shore power, or grid output by drawing energy from the battery. When the load is reduced—i.e., when loads are turned off—the energy that is then once again available in sufficient quantities can be used to charge the batteries.

Solar Power and Uninterruptible Power Supply

The device can be used with both off-grid and grid-tied PV systems, as well as with other alternative energy systems. It can be used with both solar charge controllers and grid-tied inverters. The main output ensures uninterrupted operation. In the event of a grid outage or an interruption in the off-grid/generator power supply, the MultiPlus-II takes over the power supply to the connected loads. The switchover occurs so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed. The second output supplies power only when AC power is available at the MultiPlus-II’s input. Loads that must not discharge the battery, such as a water heater, can be connected to this output.

System Expansion, Configuration, and Remote Monitoring

Settings can be changed in just a few minutes using the VEConfigure software (this requires a computer or laptop and an MK3 USB interface). Several monitoring and control options are available: Color Control GX, Venus GX, Octo GX, CANvu GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart Dongle), battery monitor, and Digital Multi control panel.

Install a Color Control GX or other GX products to connect to the Internet. Operating data can be stored and viewed for free on our VRM (Victron Remote Management) website. If systems are connected to the Internet, they can be accessed remotely and settings can be changed.
