In our 2002 Hawk we have the surepower 1314 to charge the house battery from the truck while we are driving.
We are adding solar.
With the solar charging the battery AND the truck charging the battery, how does that work? Will one override the other?Do the surepower and the solar work together?
I got the Morningstar MPPT charge controller if that makes a difference..
Thanks. This is a bit confusing.
Hello,
Your surepower 1314 is just a voltage sensor. It will connect or disconnect the truck battery from camper house bank based on the difference between the batteries. You didn't mention if your camper setup is straight forward or you're doing something more fancy ie switchable house banks, or a separate load connection. The surepower allows for many configurations. Assuming you just have the truck battery connected to the surepower and the camper house bank (or the DC panel of the camper) connected to the other side of the surpower you can hook the morningstar direct to the camper house bank( or again the dc panel of the camper). Your morning star will have 3 sets of connectors, solar input, battery, and load. Take the battery set direct to either the main input of the dc panel, or direct to the camper battery bank. Let each device do it's own thing. Worst case would be the solar keeps the camper battery charged enough that the surepower keeps things connected and you also charge the truck. If you don't want this to occur, after you shut down the truck leave the headlights on a few minutes. This will cause the truck battery voltage to go down and the surepower will disconnect. I have the same thing happen with my truck because my camper house bank is so much larger than the truck batteries. I run a different connect device, but it works the same way. Mine will disconnect with the headlights on after about 3 minutes.
Feel free to PM if you have other questions
