I like the idea of using server power supplies.
I was thinking that the 17 volts would feed a charge controller so no need to mess with them. Can't it work like that?
We tend not to think we might be without power for long here in Britain but we lived for 11 years on a Scottish island fed by a single undersea cable from the mainland. Something went wrong one winter and the whole island was without power for 3 days.
I have been trying to find out what the lowest input voltage needs to be for a charge controller as I will have to make sure I wire up the power supplies to at least reach this level but up to now all I can find is the maximum voltage and power. Does anyone know any values please?
