We have purchased a boat with an existing Multiplus Compact and would like to replace the failing AMG's with Lithum LiFeP04 batteries and continue to use the MultiPlus for charging when connected to shore power.
Model - Multiplus Compact 12/1600/70 - 16.
Product Code - CMP121620000
Serial Number - 11200303799
Mircoprocessor - 1906137
We have access to the device using ve.config via an MK3-USB device should any settings or firmware need updating.
Hi, you don't explicitly ask a question here, but are you requesting details on how to set up the inverter for the lithium batteries?
Firstly you need to chose the lithium battery to comply with the voltage range of the invertwer - lithium batteries tend to operate at a slightly higher voltage, so check the maximum voltage of the battery is compatible with the inverter. For 12V systems this should not be an issue. You then need to select a BMS system to monitor the battery - operating at 12v rules out some systems, so make sure these are compatible. The BMS then needs to be programmed with the battery parameters - it's usually better to get the battery and bms pre-configured unless you are confident about doing this your self.
Programming the inverter is relatively straight forward - using the Victron system configure app. you will need to program the voltage and capacity parameters, and also configure how the BMS will shut down the inverter for under and over voltage conditions. This is best done with a VENUS device as it will also give you more information about the state of the battery.
