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 or 100 A. The MultiPlus-II is best suitable for professional sea travel, yachts, vehicles and land-bound, network-remote applications. The device also has a built-in anti-islanding function and is being approved for an ESS application in more and more countries. Several different system configurations are possible. For more information, see the ESS Design & Configuration Guide.
Powercontrol and PowerAssist – increasing power or generator output
A maximum line or generator current can be set. The MultiPlus-II then takes into account other connected AC consumers and uses only the current that is "left" to charge the battery. This prevents the generator or the mains connection from being overloaded (PowerControl function). The PowerAssist function takes the PowerControl principle to a new level. Load peaks often occur for a limited period of time. In such a case, the MultiPlus-II immediately compensates for weak generator, land current or mains power by energy from the battery. If the load is reduced, i.e. if consumers are switched off, the energy that is then available again can be used to charge the batteries.
Solar power: Alternating current even in case of power failure
The MultiPlus-II can be used for both non-grid coupled and grid-coupled PV systems as well as other alternative energy systems. It can be used with solar charging controllers as well as with mains-connected inverters.
Two AC outputs
The main output ensures uninterrupted operation. In the event of a power failure or interruption of the generator/generator current, the MultiPlus-II supplies the connected consumers. The switchover is performed so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is ensured. The second output provides power only when AC power is available at the MultiPlus-II input. Consumers who are not allowed to discharge the battery, such as a water heater, can be connected to this output.
Virtually unlimited power through parallel and three-phase operation
Up to six multis can be connected in parallel for hohem power requirements. This results, for example, in six 48/5000/70 units 25 kW/30 kVA output power with 420 A charging capacity. Apart from the parallel port, three units of the same model can also be configured for a three-phase output. But that's 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 local control
The settings can be changed within a few minutes with the VEConfigure software (a computer or laptop and an MK3 USB interface are necessary for this). There are several monitoring and control options available: Color Control GX, Venus GX, Octo GX, CANvu GX, Laptop, Computer, Bluetooth (with optional VE.Bus smart dongle), battery monitor, digital multi control panel.
Remote configuration and monitoring
Install a Color Control GX or other GX product 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.
GX/LCD display
A backlit display with 2x 16 characters shows the system parameters.
