Victron MultiPlus-II 48/3000/35-32
Our new inverter/charger
The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid.
It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A).
It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.
Note: for a short period of time this product was called MultiGrid-II.
Automatic and uninterruptible switching
In the event of a supply failure or when the generating set is switched off, the MultiPlus-II will switch over to inverter operation and take over the supply of the connected devices. This is done so quickly that operation of computers and other electronic devices is not disturbed (Uninterruptible Power Supply or UPS functionality). This makes the MultiPlus-II highly suitable as an emergency power system in industrial and telecommunication applications. The maximum alternating current that can be switched is 16A or 50A, depending on model.
Auxiliary AC output
Intended for non-critical loads and directly connected to the AC input. With current measurement circuit to enable PowerAssist (see below) and ESS functionality (see section 2.3).
Three phase capability
Three units can be configured for three-phase output. Up to 6 sets of three units can be parallel connected to provide 45 kW / 54 kVA inverter power and more than 600A charging capacity.
PowerControl – maximum use of limited AC power
The MultiPlus-II can supply a huge charging current. This implies heavy loading of the AC mains or generator. Therefore a maximum current can be set. The MultiPlus-II then takes other power users into account, and only uses ‘surplus’ current for charging purposes.
PowerAssist – Extended use of generator or shore current: the MultiPlus-II “co-supply” feature
This feature takes the principle of PowerControl to a further dimension allowing the MultiPlus-II to supplement the capacity of the alternative source. Where peak power is often required only for a limited period, the MultiPlus-II will make sure that insufficient AC mains or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is used to recharge the battery.
The MultiPlus is equipped with a programmable relay. The relay can be programmed for different applications, for example as a starter relay for a generator.
External current transformer (optional)
External current transformer option to implement PowerControl and PowerAssist with external current sensing (max. 32A).
Programmable analog/digital input/output ports (Aux in 1 and Aux in 2, see appendix)
The MultiPlus is equipped with 2 analog/digital input/output ports.
These ports can be used for several purposes. One application is communication with the BMS of a lithium-ion battery.
