Hello all.
Bob I so enjoy your videos.
Since you all are doing solar in real world I figured you would be best to ask this question to.
I am getting a 6'X10' enclose trailer with a V nose. This is to transport and store my RC airplane gear.
I would like to build a solar powered recharge station for the batteries the planes use. Although currently doing so from the car battery at the field, you are usually limited to recharging about 2 of them before having to start the car, or risk needing a jump start.
Totaling up all my batteries, I have about 50 Ah of possible draw from a storage battery. This is figuring if every battery I have was at Zero which will never happen.
Equipment I am looking at:
1 300 Watt 24 volt panel (about the largest I could fit on top). OR
1 200 Watt 24 volt panel. (or duel 100 watt panels in parallel.
MPPT Charge controller 40 watts or larger.
2X 6 volt 250AH golf cart batteries (not sure the brand friend is helping me out here)
Other than a few LED lights, and a 6" roof vent (running durring the day only) I only need high power to recharge the batteries.
With a 250 AH battery take out 25% capacity, I would need to recharge back into the Storage batteries about 63 amps. Not sure If I would ever discharge that far but it is possible.
It takes about 1 hour 20 minutes to recharge one 6AH lipo battery. and it could be an hour or more before I recharge another one, all my other batteries are smaller.
Now the trailer will be parked where it will receive what ever sun there is all day with the panels flat. And it would be days before I go out to the flying field again.
On another forum, I am being told this will never work, that I would never be able to recharge to golf cart batteries back up to full, they would sulfate and die an early death.
Many of you on here are living with minimal solar setups. Am I throwing my money away or would this work.
There is another guy at the field he uses 4 golf cart batteries, but he plugs into AC at home to recharge them. Id rather just let the sun do it.
