Yup. My system is properly designed. Thank you. I was just giving the ACR more credit than it deserves regarding its intelligence.

@Utah KJ did you redo the systems because you were having problems with it? Or was it to ensure that both sides were 100% isolated? After looking at it and learning more im not really seeing a negative. Worst case a few aHs get pulled out of my house battery, they isolate, then it all gets...

@john61ct that makes perfect sense. Didnt really think about that. This dual battery/solar stuff is kind of a new realm for me.

Now I understand. Yeah it would be nice if the blue-sea had a disconnect voltage closer to 13. But it seems like now both batteries are benefitting from the solar accidentally on my part.

This is exactly what happens. It seems like I was giving the ACR more credit than its worth. Its really just a fancy safety switch. Everything is working normal and how it’s supposed to. Just surprised the discussion isn’t more common. Or are people not really diving into what’s going on with...

Yeah I guess you’re right. Ground is ground. I’ve been working on electrical systems for a long time. But this is my first time “engineering“ one. Been a fun experience and know a heck of a lot more now than when I started.

@john61ct What would the design flaw be? Seems to me like the monitor and solar are working perfectly. It also seems like dumb luck that I connected the second battery ground to the starting battery. If not my monitor would probably not be seeing the discharge.

Well I’m a giant dummy. Thank you @rayra i just did a parasitic drain test on the truck batt. Seeing about 100mA which is in line with all the electrical stuff in newer vehicles. I guess inadvertently my solar will be helping the truck battery too. not too worried about it now I guess. Worst...

Just wrapped up my dual battery and solar setup. The starting battery is connected to a northstar group 31 AGM via the blue sea ACR and disconnect. On my Victron monitor I am seeing about 100 - 200 mA discharge from the AGM into the truck battery (solar and all loads disconnected from the house...

Got my rotopax mounted this morning and went to get some quarantine mall crawler glamour shots. Also got my goal zero lights in. Didn’t want fixed lights in there. Attached a bunch of nylon webbing loops that I can clip into.

And the interior...

Have a build thread over in domestic full-size but figured I’d throw my nearly “completed” build pics over here. Starting with the exterior...

Finally some updates. Been hammering away the last several days. Dual battery system completed. Solar completed. All wiring in the back completed. And the left side bench is completed!

Wow! Awesome work and a beautiful Interior!

Couldn’t agree more. If I could go back in time I would have kept my ‘07.

Ben in a holding pattern waiting on parts. Got my group 31 battery in yesterday. Ordered 170w panel and a controller. Extrusions to finish out the left side bench should be here Thursday!

Seems like a valuable use of time...

@MTVR Dude. Did you revive this old thread just to talk trash and troll?

Man that thing is awesome! @Ultimark Seems like damage imposed on the bank is minimal. Way less than what otters, muskrat and moose do anyway.
