I have RV w/180 watt solar to MPPT 75/15 controller direct to house batteries terminals. House is two 6v golf cart wired for 12v. I am adding BMV-702 w/dongle. Three cables connect to a common positive post: 1 from positive terminal of house battery, 1 from 12v feed from the engine battery, 1 to the fused 12v/110v charger/LPG generator Parrallax Progressive Dynamics power charger distribution center. Cables are 8awg.
I plan to mount shunt per the instructions (battery positive to shunt, shunt to common post, post to 12v/110 power center). What do I do with the 12v feed from engine battery? It is the primary source for recharging the house while driving. I'd rather not wire the engine battery as #2. The feed is 18 feet 12awg wire.
Thanks in advance for any guidance!
