I’ve got a 30 ft Catalina. Older one. Replaced old wiring and batteries. Used the 7650 add a battery from Blue sea. Also battery monitor. All working good. Finally got fridge working on 12 volts. Over night fridge kills house battery when no solar charging. My house is I believe 800 amp. I’m thinking of adding a second or 3rd battery for house. Do i need to add another 7650 and ACR. Was going to have the 2 or 3 more house batteries in Parallel. I know guys have more than one house bat but do they also have a separate charging for each controlled by an ACR.

What is your current house bank, I would be doubtful you have 800ah bank. Even at half that you should have 3 days with no additional charging. Odds are you have an 800cca start battery running your fridge.

Ya. I believe my house is 800 amp bat. The fridge draws 5 amp and runs intermittent. It’s a good box. What i did also was not shut off the on/off switch also that night. The battery monitor only draws a small amperage. It’s LED. Only other thing is the bilge whic might of kicked in once if that. Engine did start as the BS controller locked it out. Just house voltage was about 4 when i got to it. I know i need another one or two house batteries. What I’m kind of looking for is if i need another couple BS switches and combiners for the extra bank of batteries. I was thinking to have them in parallel

800ah battery or bank...? If you think you have an 800ah single battery you do not. Even if your fridge drew 10 amps that’s 80 hours of continuous use. I am certain you are running an 800 cold cranking amp start battery with maybe 80 amp hours, which is more in tune with your overnight battery drain. I would suggest you start doing some battery and electrical research before you do something regrettable. This stuff can kill you if done wrong and you’re on track for an award. The questions and statements you’re posting show you need outside help or a good crash course to give you a healthy respect for this stuff.

Ditto, that's what I thought as well.

Well, that went well didn't it.

You got a good response, apparently not to your liking and so spat the dummy. Goodbye.

Guess I could have left out the award comment. Not everyone can laugh at themselves I guess.

OK, lets reset. Your house bank is 800amps. What is your setup? how many batteries of what type make up that bank? Is it regular lead/acid, AGM, lithium? without the fridge on, can your solar fully recharge the bank in a day, and how many watts is your solar?
