i'd like the solar panels to charge both house and coach batteries if possible, and am considering two options:
- one, add a positive wire between both batteries (assuming they're grounded to the same setup) so any overage from the house battery trickles down to the coach battery
This will initially cause the higher voltage battery to discharge to the lower voltage battery and then solar will charge both during the day and both will discharge at night due to whatever is causing the excessive drain.
- two, change the momentary battery boost button to an actual toggle (and leave it on), assuming that this won't screw up the larger converter or other systems This will add the additional drain of the solenoid to the above.
any advise is appreciated... if i'm clear to go option one (which i prefer), is there a shorter path to connect both batteries together instead of routing an 8gauge wire between house steps and engine bay? Yes the battery boost solenoid.
thank you!
