Connecting solar panel charge controller to house batteries

[moe58]

Hi all

I am currently installing solar panels on my SO 389. I have 3 house batteries in the aft portside storage locker; two under the floorboard and one under the tool drawers. I am not sure how to connect the output cables from the charge controller. Is it OK to connect them to the positive and negative on the battery under the drawers only or should I be connecting them to all 3 batteries, and if so how? Any advice is appreciated.

Cheers

Positive wire from the charge controller will go on the main positive post of the house batt bank.

If you are using Battery Charge Monitor then negative wire from the charge controller should go to shunt labeled LOAD/CHARGE (the other side of the shunt is labeled Battery).

If not, then connect to main negative post usually located on your main batt switch.
