John in CR said:I was waiting to prove your thing worked before sending the free panels, but this is proven and cheaper, and best of all I don't have to build it, so what voltage to you run again, so I know how many modules to send your way?

These things should work great up to their maximum rating of 35v. With a solar system, it should be possible to put these in series to make higher voltages. I'm not sure what the reverse drain (like you'd get at night) is. I can try to measure it. A diode may possibly be helpful.
I have a 12v standby power thing I'm working on. It will really be 4s li-ion, so more like 16.8V charging. I want to feed my cable modem and wireless router so I can still maybe get internet access during a power failure.
Pete: you're right about a lead-acid charger dropping its CV setting once the current gets below a certain point. This should essentially drop the charge current down to zero, at least for a while. With a timer or some other cutoff mechanism, you could just stop the charger. This would work about the same as the CC/CV board.
