I want to buy 3 of the 480W pannels, series hookup of course, so I need to size my charge controller accordingly to charge a bank of 12V x 200 ah batteries. I have a charge calculator I found online, but it needs the figures for the "T" in the STC for each panel, I do not see that in the spec sheet. Or else I'm blind!! Thanks
It's not exactly clear what did you mean by T in STC. A charge controller for 3 x 480V panels and 12V battery should have at least 150V maximum voltage (preferably 200) and at least 40A, if we're talking about series hookup.
