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. SO.. Q1 Because 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?
Q2 The controller hooked to battery has two LD indicator lights lit all the time. Can they drain the batteries over time?

Do you have an inverter or is it all 12v?

No inverter. All 12V. If I need AC I'm either plugged in or on a generator.
