That`s great to hear Jim. I consider buying the Eco-Worthy 20a MPPT charge controller.
But it`s still Voc 15-42V DC? If a 100W solar panel has Voc 21.6V does that mean I can`t have them in series with the Eco-Worthy controller? (21.6 x 2 = 43.2V)
If that's an issue I'm using the 20A Tracer $115 with 2 100w 22.5 Voc panels wired in series.
