Victron  MuliPlus-II 48/5000/70-50 230V

A MultiPlus, plus ESS (Energy Storage System) function
The MultiPlus-II is a multifunctional inverter/charger with all the functions of the MultiPlus and an additional function, namely that of an external current sensor. This extends the PowerControl and PowerAssist functions to 50 A and 100 A respectively. The MultiPlus-II is ideal for professional marine use, yachts, vehicles and land-based, off-grid applications. The device also features a built-in anti-islanding function and is receiving approval for ESS applications in more and more countries. Several different system configurations are possible. Further information can be found in the ESS Design & Configuration manual.

PowerControl and PowerAssist – Increasing grid or generator power
A maximum grid or generator current can be set. The MultiPlus-II then takes other connected AC consumers into account and uses only the current that is still "left over" to charge the battery. This prevents the generator or the grid connection from being overloaded (PowerControl function). With the PowerAssist function, the PowerControl principle takes on a new dimension. Load peaks often occur only for a limited period. In such a case, the MultiPlus-II immediately compensates for insufficient generator, shore power or grid power with energy from the battery. If the load is reduced, i.e. consumers are switched off, the now again sufficiently available energy can be used to charge the batteries.

Solar power: AC power even during a power outage
The MultiPlus-II can be used with both off-grid and grid-connected PV systems as well as other alternative energy systems. It can be used with both solar charge controllers and grid-connected inverters.

Two AC outputs
The main output ensures uninterrupted operation. In the event of a power outage or an interruption of the shore/generator power, the MultiPlus-II takes over the supply of the connected consumers. The switchover happens so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed. The second output only supplies power if AC power is available at the input of the MultiPlus-II. Consumers that are not allowed to discharge the battery, such as a water heater, can be connected to this output.

Practically unlimited power through parallel and three-phase operation
Up to six Multis can be connected in parallel for high power requirements. This results, for example, with six 48/5000/70 units in 25 kW/30 kVA output power with 420 A charging capacity. Apart from the parallel connection, three units of the same model can also be configured for a three-phase output. However, that is not enough: by connecting up to 6 sets of three devices in parallel, you get 75 kW/90 kVA inverter power or 1200 A charging current.

System configuration, monitoring and control on site
The settings can be changed within a few minutes using the VEConfigure software (a computer or laptop and an MK3-USB interface are required for this). 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, Digital Multi control panel.

Remote configuration and monitoring
Install a Color Control GX or other GX products to connect to the internet. The operating data can be stored and viewed free of charge on our VRM (Victron Remote Management) website. If systems are connected to the internet, they can be accessed remotely and settings can be changed.
