Multi-functional, with intelligent power management
The MuitiPlus is a powerful true sinewave inverter. a sophisticated battery charger that features adaptive charge technology, and a high-speed AC transfer switch in a single complact enclosure. Next to these primary functions, the MultiPlus has several advanced features, as outlined below.
Two AC Outputs
The main output has no-break functionality. The MultiPlus takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20m Sec) that computers and other electronics equipment will continue to operate without disruption. The second output is live only when AC is available on one of the inputs of the MultiPlus. Loads that should not discharge the battery, like a water heater for example, can be connected to this output (second output available on models rated to on-models rated at 3kVA and more.
Virtually unlimited power due to Parallel operation
Up to 6 Multis can operate in parallel to achieve higher power output. Six 24/5000/120 units for example will provide 25kW / 30kVA output with 720A charging capacity.
Three phase capability
In addition to parallel connection, three units of the same model can be configured for three phase output. And up to 6 sets of three units can be parallel connected for a huge 75kW/90kVA inverter and more that 2000Amps charging capacity
A MultiPlus, plus ESS (Energy Storage System) functionality
The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid.
It has all the features of the MultiPlus, plus an external current sensor option which extends the PowerControl and
PowerAssist function to 32A.
It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.
PowerControl and PowerAssist - Boosting the capacity of grid or generator power
A maximum generator or grid current can be set. The Multi will then take account of other AC loads and use whatever is extra
for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function).
PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a
limited period, the Multi will compensate insufficient generator, shore or grid power with power from the battery. When the
load reduces, the spare power is used to recharge the battery.
ESS: Energy Storage Systems
The MultiPlus can be used in off grid as well as grid connected PV and other alternative energy systems.
Several system configurations are possible, for more detailed information see the ESS Design and configuration manual.
On-site monitoring and control
Several options are available: Battery Monitor, Digital Multi Control Panel, Color Control Panel, Bluetooth (Venus GX or Color Control panel needed),
laptop or computer.
Remote configuring and monitoring
Install a Venus GX or a Color Control Panel to connect to the internet.
Data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
When connected to the Ethernet, systems can be accessed remotely and settings can be changed.
