Page 5: Description
Automatic and uninterruptible switching If the AC generator is switched off or fails, the MultiPlus-II will switch over to inverter operation and take over the supply of the connected devices. This is done so quickly that the operation of computers and other electronic devices is not disturbed (Uninterruptible Power Supply or UPS functionality). -
Page 6: Battery Charger
Programmable analogue/digital input/output ports (Aux in 1 and Aux in 2, see appendix) The MultiPlus-II is equipped with 2 analogue/digital input/output ports. These ports can be used for several purposes. One application is communication with the BMS of a lithium-ion battery. -

Page 8: Operation
If the voltage at the ‘AC-in’ terminal is rejected, the inverter will switch on. When the switch is switched to ‘charger only’, only the battery charger of the MultiPlus-II will operate (if an AC voltage is present). In this mode, the AC input voltage is also switched through to the ‘AC out’ terminal. -

Page 12: Connection To The Vrm Portal
MultiPlus-II inverter/charger off-grid Australia For a 3kVA unit With its PowerAssist feature, the MultiPlus-II can add up to 3 kVA (that is 3000 / 230 = 13 A) to the output during periods of peak power requirement. Together with a maximum input current of 32 A, this means that the output can supply up to 32 + 13 = 45 For a 5kVA unit, this is an additional 22A (5000/230), so the maximum output is 50+22=77A. -
