My rig has a house battery manual disconnect that I've used before when storing the RV for a long period of time. Now that I've added solar to the rig, I'm wondering if it is still okay to use the manual disconnect. The Rover controller installation instructions make it clear to connect the battery before the solar panels.
Will disconnecting the battery while the panels are still connected to the controller cause problems for the controller? It seems like the system would then be in the situation described by the warning... If I'm going to disconnect the battery, do I have to disconnect the solar first?
I would not wire the controller thru the disconnect, wire the controller so you can use the disconnect to disconnect the RV from the battery while solar is still connected. If you need to remove the battery then disconnect a panel wire from the controller before disconnecting the controller from the battery.
I'm getting a bit confused. I have a 3yr old 14' toy hauler with two new typical flooded deep cell batteries. I have not yet connected the single 100W solar panel itself, but have installed all the electrical from roof to battery in AWG 10 stranded. I only need to charge the batteries, but I want optimum efficiency. I have the Renogy 30A PWM ‘Wanderer’ series controller. The red/hot configuration goes: solar panel > 20A manual breaker - > 20A toggle switch - > controller (in) - then Controller (out) to 20A thermal auto-reset breaker - > on to battery. The black/neg goes: solar panel > Controller - Controller > battery. The first 20A (manual reset) breaker is to be a safety cut off of all current to the controller from the panel. The toggle is to turn the panel 'on/off' at will with the panel 'live'. The thermal auto-reset breaker downstream of the controller is to protect the controller from thermal over-current conditions from the battery side. I agree it could be a bit overkill, but it reflects the advice so far. The breaker/toggle is meant to separate the panel from the battery pre-controller. As long as either/both are off, can I not disconnect/connect the batteries at will? One other Q - the controller hooked to battery has two LD indicator lights lit all the time. Can they drain the batteries over time?
