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
for House (12v)
I'm going to have two separate solar panels
, one for the house, one for the engine
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
; 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.
