A 750 watt inverter is plenty, just ensure you get a pure sine wave unit to ensure spikes dont harm any of your electronics. If the battery is new, check what size and type it is, and add a second matching one. Your CPAP will use 40 or so amps per night a little more if you use the humidifier, maybe a little less if you dont. With 2 batteries you should have 150 to 170 amps available so you wont be pulling the batteries below 50%.
As you know you can charge the batteries from your generator, but be advised, it will likely charge it to 85-90% fairly quickly, but getting the last part takes a long time, which is what solar is great for.
Good luck and enjoy the journey.
First, thank you! Now i understand how much amp hours i need for the second battery. I’m going run them in parallel, and charge them with the generator for now, and top off with a trickle charger from my truck if needed. I have picked out a 700 watt pure sine inverter for mounting inside the trailer, and then I’ll attach it directly to the battery bank. If I can find a decent price I’m going to get a quick connect for the inverter so if I need to, it will be easy to disconnect it so there will be no draw on the battery. By quick connect I mean installing the inverter direct to the battery, which a switch between the inverter and battery bank.
