Just purchased an 8.5’ X 20’ enclosed trailer to haul my race car to the track, I am going to add 2 solar panels (180-210 watts, each) and batteries to supply power for lighting, stereo, Laptop, 12volt winch, misc electrical tools.
I will not have much control over pitch or direction of the panels so they will be close to flat with just enough pitch to keep rain running off. I will pitch them to take advantage of where it parked at home, when in use I will keep the pitch in-mind when parking.
The trailer will be parked at the race track usually for two days sometimes 3 days, I will have NO AC power available, I will be limited to 4-6 batteries based on weight and space so I will have a small generator that I will run only when I have to (yes it can charge the batteries while running), too noisy and I don’t want to disrupt the people parked next to me. I will also use the battery bank as a misc source of power while packed at home and in the woods for quad trips.
I am no solar or battery expert so I would like to learn from the expertise of the forum members.
Considering limited space and trying to keep the weight down I would to keep it to 4-6 batteries with maximum amp hours.
What is going to be my best bang for amp hours, 4-6 6v batteries in series/parallel or 4-6 12v batteries in parallel?
Please recommend type of batteries for my application?
I would like to charge the batteries from the truck alternator while the engine is running, from the solar panels most of the time, from AC power when available and from the generator only when needed.
I know that I will need a charge controller and DC to AC convertor, please recommend type and possible brand that would be most effective for my application?
What else would I need to make this happen???
Am I on the right track???
