Victron energy MultiPlus-II GX User Manual

5. Product Description
The basis of the product is an extremely powerful sine inverter, battery charger and transfer switch in a compact casing. It is suit-
ed for use in Marine, Automotive, as well as stationary land-based applications.
5.1. Features applying to all applications
5.1.1. GX LCD display
A backlit 2 x 16 character display screen shows system parameters.
5.1.2. BMS-Can Connections
The BMS-Can connection allows connecting of compatible 500 kbps CAN-bus BMS batteries. VE.Can products as for example
Victron MPPT Solar Chargers, or a Lynx Shunt VE.Can are NOT supported.
5.1.3. Ethernet and Wifi
Ethernet and Wifi connections allow for local and remote system monitoring, as well as connection to Victron's free VRM portal for
long term system performance information.
5.1.4. Automatic and uninterruptible switching
Houses or buildings with solar panels or a combined micro-scale heating and power plant or other sustainable energy sources
have a potential autonomous energy supply which can be used for powering essential equipment (central heating pumps, refriger-
ators, deep freeze units, Internet connections, etc.) during a power failure. A problem is however that grid connected sustainable
energy sources drop out as soon as the grid fails. With the product and batteries, this problem can be solved: the product can
replace the grid during a power failure. When the sustainable energy sources produce more power than needed, the product
will use the surplus to charge the batteries; in the event of a shortfall, the product will supply additional power from the battery.
5.1.5. Two AC outputs
Besides the usual uninterruptible output (AC-out-1), an auxiliary output (AC-out-2) is available that disconnects its load in the
event of battery operation. Example: an electric boiler that is allowed to operate only if the genset is running or shore power is
available. There are several applications for AC-out-2.
5.1.6. Three phase capability
The unit can be connected with others and configured for three-phase output. Up to 6 sets of three can be parallel connected to
provide 45 kW / 54 kVA inverter power and more than 600A charging capacity.
5.1.7. PowerControl – maximum use of limited AC power
The product can supply a huge charging current. This implies heavy loading of the AC mains or generator. Therefore a maximum
current can be set. The product then takes other power users into account, and only uses 'surplus' current for charging purposes.
5.1.8. PowerAssist – Extended use of generator or shore current
This feature takes the principle of PowerControl to a further dimension allowing the product to supplement the capacity of the
alternative source. Where peak power is often required only for a limited period, the product 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.
5.1.9. Programmable
All settings can be changed with a PC and free of charge software, downloadable from our website www.victronenergy.com. See
this manual for more information - https://docs.victronenergy.com/veconfigure.html
5.1.10. Programmable relay
The product is equipped with a programmable relay. The relay can be programmed for different applications, for example as
a starter relay for a generator.
5.1.11. External current transformer (option)
External current transformer option to implement PowerControl and PowerAssist with external current sensing
5.1.12. Programmable analog/digital input/output ports (Aux in 1 and Aux in 2, see appendix)
The product 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.
