    Solar vs battery disconnect

    I have an 395 ms momentum.

    I'm looking for clarification of the solar disconnect and battery disconnect ,

    Can i leave the solar connected , thus charging the battery, while I disconnect the battery (load from the RV)?

    How do these two separate disconnects work together?

    On our 351 the solar charger is wired directly to the battery, and thus bypasses the Battery Disconnect Switch. If you have the complete solar system, it will work differently.

    Since I don't have your setup I can't comment directly, but typically the leads supplying power from the solar charge controller run directly to the battery. So if that's the case for you, you could charge the battery from the solar while having the disconnect from the loads in place. Can you trace the leads from the charge controller and see if they run directly to the battery?

    I was thinking that is the way it should work.
    Thank you.
