I am helping with a sign project, this is a charitable / memorial thing, not for profit. I have two trojan 6v agm
batteries, and 45 watts of solar. we want to run about 32 watts of 12 volt leds, in order for the solar that we have to be adequate especially during short winter days, the best idea I have is a controller to turn the load
on at dusk and then off 4-5 hours later, however I do not know if such a thing is available and I do not have the knowledge to design it. I also have a 12 volt photo control I purchased off e-bay last year for a project I never got around to, I don't know if it will carry 32 watts, I was considering using an automotive relay
but I was first going to check how much current it uses just to close the contacts.
purchasing more solar is an option, just wanted to check with you guys for ideas first.
I would be open to paying to have something made or trading for sign type white leds if anyone is interested.
thanks
