I am considering using BlueSolar PWM with 20W total in PV panels on a small boat. We are talking 5m boat.
I would be connecting it to starter battery in order to keep it charged during long periods of not using the boat. On that battery there are some small loads as well, like radio, echo, lightning. We are talking about 12V/50Ah battery.
I would move those loads on a load connection available on pwm, engine directly to the battery and of course pwm directly to the battery.
There is a safety switch on board that is suppose to cut the battery off from the grid completely.
I am wondering if I would be cutting a battery away from BlueSolar PWM, how would that unit take that action and what would happen with power to connected loads (in case there is a full PV activity)?
