On a different thread someone said they mounted a portable solar panel to their vehicle luggage rack to charge the trailer battery when driving because “their TV did not charge the trailer battery”.
I’m confused.
Someone with more knowledge (not guessing because I am only guessing) PLEASE chime in.
So my understanding:
It all has to do with how many amps/hr the TV puts out vs how many amps/hr the trailer is asking for.
1. If I am running nothing in my trailer, the trailer battery should charge fine. Because nothing is using any of the TV output.
2. If I am running very little in my trailer, as in the refrigerator on LP so just the circuit board is using current, the trailer battery should charge slower. Because the circuit board is using some but less than the TV output.
3. If I am running the refrigerator on the
12v heater, the battery may not charge. If the
12v heater is drawing more amperage/hr than the TV can put out.
