This is a clone of a real nice charger.. Built in 30A load controller too! I could use that!
Open circuit voltage solar module < 47 V isn't a bad rating. Should work with a lot of panel configs.

Who knows if it's going to be as good.?. But it looks nice at first blush..
I'm thinking of ordering one to use as a backup.. Just in case of lightning this summer!
