2 x house AGM and 1 x start battery. Would you charge AGM only by solar or could they be charged by alternator
Thanks again I really appreciate all the help and feedback on this forum!
Run the shore charger, solar and alternator all
to the house bank. The VSR will charge the start as the house is charged. The house will be fully charged in a matter of minuets (assuming a healthy and full start battery upon engine
start) then your charging systems can go about charging your much more extensively used house bank. Like I said before you'll probably have to go with an AGM start battery as well as the charging profiles for the house bank (AGM's) will carry over with the VSR (could cook a FLA with the AGM charge profile; These profiles will come from your shore charger, Alt. regulator
and MPPT). You could buy a new dc2dc combiner (like the Balmar
Digital Duo) then you can mix and match batteries
, ARC's and VSR's not so much.
