I'm starting to put together a
parts list and found I was missing a few key pieces of information.
The plan is to have
AGM for start
battery and
LifePo4 for House (12v)
I'm going to have two separate
solar panels, one for the house, one for the
engine. (probably)
Currently there is an AC->DC
charger (old) and an
alternator available to charge the
batteries.
I would like to setup the following.
The
engine battery will be charged using this priority: the
Alternator;
Solar;
Shore power; jumper
cables from house (unless a B2B is required)
The House battery will be charged using this priority:
Solar,
Shore power, jumper
cables from engine w/engine running (unless a B2B is required)
I expect to have a PWM between solar and Engine battery and
MPPT between solar and House.
I've looked at Automatic Transfer Switches but they appear to be on the load side not the
charging side. Maybe I missed something. I'm trying to isolate the two systems as best as possible (personal preference, please don't judge).
Suggestions are appreciated.
