-48v Compatibility

Hi Everyone,

I'm looking at using Polarium Lithium Batteries in my system but notice they are -48v. Is there any way they could be used with a MultiPlus? Would I need to wire them in a different way, add some kind of converter or are -48v batteries not at all compatible with Victron equipment?

I understand there are 48v variants but I was looking to use a -48v battery bank. i.e: the positive terminal outputs 0 volts (ground) and the negative terminal outputs 48v.

Very odd never seen that before I would think 0 is posistive and -48 is negative use a meter to confirm and connect. looks like a 0 posistive ground system battery? Check to ground for polarity.

The inverter is battery compatible.

Maybe reading the polarium manual would help ?
