hi all,
I am assembling the componets for a solar system and I saw a news article on a diy system a guy had.
He had a 24x12v solar system and he had a unique charging system I would like to try as well. He was using a PWM system that scanned all the bats and any battery below a certain V ( I think he said 14v) got a pulsed charge. The PWM just cycled through all the bats continuously at some unknown (to me) freq and pulsed as needed to keep the 24 bats at that pre-set V.
I'm not possitive but I think he used a 24v pusing system for some reason, so I guess he set the 12v into sets but the stats he gave were great and I would like to try and duplicate it.
So during the day, he had I think 4-6 bats that received all the solar charge and then he pulsed the others from them. He also said when he grid charged he would charge the same 4-6 bats only and his PWM would pulse charge the others. This evidently kept all the bats at an even charge and they lasted longer and the whole system integrity was much higher.
Anyone have an idea how to build a PWm that would also scan 24 bats and pulse as needed. I think I would have to be able to adjust the PWM duty and freq to be able to fine tune it and of course be able to fine tune the pre-set V level for best operation.
There are a lot of PWMs available out there but not any that I can find that also will scan an inventory of batteries to pulse as well.
Any ideas?
I'm willing to exchange services or something with anyone who can come up with the best way to do the above.
Thanks
Horace
