Phoenix Multiplus 12/2500/120 good for LifePo4?

Hi,

I found a Phoenix Multiplus second hand for a decent price. Will I be able to properly charge my LiFePo4 batteries with it? I just realized that it is an older inverter/charger — can I manually set my charging profile?

Thanks!

If the battery type is set to "User Defined" then the absorption and float Voltages are programmable between 12V and 16V in 0.1V steps.
The settings are programmed in with DIP switches and push buttons. In these modern times, it's a bit clumsy but that is the way things were done back in those days.

Study the manual to familiarise yourself with the setup procedures:

Thanks again @WKirby
I will then get it (half price of a new one) and figure it out :)

@shivadas Do remember as this is an old unit, it does not have VE.Bus. It will not work with a CCGX or anything like that.
Just adding this for information if you have future plans.
