If the house bank is getting charged it could just be about amp hours in and amp hours out too! What size is the solar panel? Is there any load on the house bank like refrigeration etc? Is the solar panel mounted in uninterrupted sun? Is the panel performing, how many amps at peak? Has it been clou

My solar panel connects straight to the house battery. My alternator also connects straight to the house battery. The ACR senses voltage on the house battery and connects when it gets high enough to charge the start battery. The ACR can also be connected to sense the start battery, in which case

Brian, While I tend to agree that a cigarette lighter might not be the best solution, I hesitate to say that it won't work. In the case that the solar charge system is intended to be portable, temporary, and easy to deploy quickly it might be a very effective solution. Most cigarette lighter ada

Josh makes good points. Also, wiring the solar through a cigarette lighter port is poor advice. The gauge of wiring going from it to a house even with an ACR would never work and only be a trickle charge at best. I'm guessing the cigarette lighter wiring is probably a 16 guage, right? Thats a prob

Charlie, I have almost the same setup you have, a solar panel feeding through the controller directly to my house battery, and I have an ACR installed.  When the solar panel is putting out current after a few minutes the LED on the ACR lights which shows the two batteries are connected. The v

Depending on the ACR design and how it is setup it may sense either battery OR both batteries. If sensing both, then any time either battery voltage is greater than ~13.3ish the ACR connects the two. This is the simplest and most straightforward design but you'd have to read the owners manual. Th

My understanding is that the ACR is usually connected to the start battery and when it’s charged the relay switches to house. The controller should be connected to the start so the relay can function On Mon, Nov 23, 2020 at 10:32 PM Josh Muckley wrote: > The battery monitor is probably not setup

The battery monitor is probably not setup for a charger voltage to be entering from the cigarette lighter. To better establish the actual conditions of your setup you need to provide the terminal voltage of each of the batteries. You also need to provide the chemistry of each of the batteries. A
