Multiplus 12/3000/120 Config 3 inverter settings for lithium

Hi all,

Finally worked out how to reconfigure the Multiplus inverter/ charger for the 400Ahr of lithium batteries I have. Next question I have is if someone can reliably give me suitable settings for the DC Input shutdown, DC Input low restart and the DC Input low pre-alarm to suit my lithium batteries?

Thanks.screenshot-6.png

More than likley you would use these settings

The lowest voltage that you are allowed to go to BEFORE the BMS turns off. this is supplied from your battery maker or from what you have set the BMS to

Says its 10v is the shut off (all cells being equal that is) so leave some room

The I would set it to 11 11.2 11.4 even 12 12.1 12.2 is ok this just means it turns off sooner

Or go with the setting that are default, but thay MUST be higher than the BMS cut off as you would like the inverter to cut off before the battery is totally turned off
