MultiPlus-II GX 4. Safe Installation Read the installation instructions before commencing installation activities. For electrical work, follow the local national wiring standard, regulation and this installation instructions. This product is a safety class I device (supplied with a ground terminal for safety purposes). Its AC input and/or output termi- nals must be provided with uninterruptible grounding for safety purposes. -
Page 8: Product Description
MultiPlus-II GX 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. -
Page 9: External Current Transformer (Optional)
MultiPlus-II GX 5.2.1. External current transformer (optional) When used in a grid-parallel topology the internal current transformer cannot measure the current to or from the mains. In this case an external current transformer has to be used. See appendix A. Contact your Victron Distributor for further information about this installation type 5.2.2. -

MultiPlus-II GX During battery charging, the inverter/charger will compensate the voltage drop over the DC cables up to a maximum of 1 Volt (i.e. 1V over the positive connection and 1V over the negative connection). If the voltage drop threatens to become larger than 1V, the charging current is limited in such a way that the voltage drop remains limited to 1V. -
Page 18: Configuration
MultiPlus-II GX 10. Configuration This section is intended mainly for stand-alone applications For grid connected Energy Storage Systems (ESS) please see https://www.victronenergy.com/live/ess:start • Settings may only be changed by a suitable qualified installer with the appropriate training, and subject to local requirements. - Page 19 MultiPlus-II GX Input frequency range Input frequency range accepted. The product synchronises within this range with the AC input frequency. The output frequency is then equal to the input frequency. Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz Input voltage range Voltage range accepted.

MultiPlus-II GX This is the recommended charge algorithm for lead acid batteries. See the help files in the software configuration programs for other features. Battery type The standard setting is the most suitable for Victron Gel Deep Discharge, Gel Exide A200, and tubular plate stationary batteries (OPzS). - Page 21 Note: when WeakAC is on, the maximum charge current is reduced by approximately 20%. BoostFactor This value adjusts the PowerAssist behaviour. If you are experiencing issues with PowerAssist (e.g. overload), please consult with a specialist trained by Victron Energy before attempting to modify. Programmable (AUX) relay The relay can be programmed for all kinds of other applications, for example as a starter relay for a generator.
