Hello guys. I have a client who wants to buy MPPT charge controllers. He wants a charge current of 20A at 24V configuration and a total input PV array of 650watts.
I tried all suppliers in China and a few in Europe and they don’t seem to have that spec. The spec that can handle 650W are the 30A ones but client insists on 20A.
Can anyone please help me with a supplier of there is any such controller on the market?
