I just bought a travel trailer that I'm keeping at my off-grid property. I'm planning to get a 100 watt solar kit (no, not HF) or assemble a similar system that I can add another 100 watt panel to if needed so as to run the basic appliances, lights plus a small TV without needing a generator. My question is how to connect the controller to the batteries? Might get a generator before next summer to run the ac since I live in Las Vegas. The trailer has 2 fla batteries on the tongue connected to a battery switch with 1, 2, 0 and both positions like a boat. Do I connect to one battery, to the house side of the switch or some other way? I've looked for an answer online but all I find is how to connect batteries in parallel or series which doesn't answer my question. Either an explanation or direction to where to find the answer is much appreciated. Thanks in advance.
