If you want to use them, Schottky types would be preferable, 100V 100 amp Like These Big high current bridge rectifiers are pretty cheap on AliExpress. And you are correct, its difficult to get them to current share, I normally have each controller programmed for a max current limit, so under bulk charge they share current equally. Your controller looks very good. Cheers Mike
