I have a 6X10 Enclosed trailer. I am planning on installing 2X 100 watt panels on the roof, to either Golf cart batteries or some sealed lead acid type. (still searching on the batteries)
The set up will be use to recharge RC Aircraft batteries. Most are small but I do have a few 6000Mah ones. The charger I will be using has a low voltage cut off so I will not have to worry about taking the storage batteries below 50%. I may only fly once/twice a week so plenty of time for the system to recharge the storage batteries, trailer will be parked in full sun when it shines.
I also want to install a small roof vent fan that only needs to run durring the day.
A few options I have are:
1) A separate solar vent fan, but most do not have good life expectancy, or will only work in full sun.
2) Tap directly off one of the panels to drive a small computer fan. not the best option.
3) Find a charge controller that will turn something on only durring the day (BEST OPTION)
4) Use a timer or some other relay function that will shut the fan off at night, or when the panel output falls too low.
Does anyone know of a CC that would turn a load ON durring the day as opposed to night as most do?
We are talking a 6"- 8" DC Brushless fan, just needs to move enough air to keep the trailer from becoming an oven. Trailer is white.
