MultiPlus II 48/5000/70-50 

5000VA Sine wave inverter + 70A IUoU battery charger + 50A mains priority circuit

The complete function of the proven MultiPlus + ESS (Energy Storage System) for home storage solutions.

The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid. It has all the functions of the MultiPlus plus an option of an external current transformer to implement the PowerControl and PowerAssist functions and, to optimise self-consumption with external current sensing (max. 32 A).
The MultiPlus-II is ideally suited for professional marine, yacht, vehicle and land-based, off-grid applications. and, to optimise self-consumption with external current sensing (max. 32 A).

It also offers all the features of the MultiGrid with the built-in anti-islanding function and a growing list of countries where it is approved.

Note: For a short period of time, this product was called MultiGrid-II.

PowerControl and PowerAssist - increasing grid or generator power

A maximum grid 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 over' to charge the battery. This prevents the generator or the mains connection from being overloaded (PowerControl function).
The PowerAssist function adds a new dimension to the PowerControl principle. Load peaks often only occur for a limited period of time. In such a case, the MultiPlus-II immediately compensates for insufficient generator, shore power or mains power with energy from the battery. If the load is reduced, i.e. if consumers are switched off, the sufficient energy available can be used to charge the batteries.

Solar power: alternating current even during mains failure

The MultiPlus-II can be used with both non-grid-connected and grid-connected PV systems, as well as with other alternative energy systems. It can be used with solar charge controllers as well as with grid-connected inverters .

Two AC outputs

The main output ensures uninterrupted operation. In case of a mains failure or an interruption of the shore / generator power, the MultiPlus-II takes over the supply of the connected loads. The switching is so fast (in less than 20 milliseconds) that an uninterrupted operation of computers and other electronic devices is guaranteed.
The second output provides power only when AC power is available at the input of the MultiPlus-II. Consumers that must not discharge the battery such as a water heater, can be connected to this output.

Virtually unlimited power through parallel and three-phase operation (not available for the 8k and 10k models).

Up to six Multis can be connected in parallel in case of high power demand. For example, this gives 25kW/30kVA output power with 4200A charging capacity for six 48/5000/70 units.
Apart from the parallel connection, three units of the same model can also be configured for a three-phase output. But that's not all: by connecting up to 6 sets of three units in parallel, you get 75kW/90kVA inverter power or 1,200A charging current (18 units required).

On-site system configuration, monitoring and control

Settings can be changed within minutes using the VEConfigure software (requires a computer or laptop and 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, Digital Multi control panel.

Remote configuration and monitoring

When coupled with a GX device (e.g. Cerbo GX, Color Control GX) you can monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto starting a backupgenerator and more…"
