Hello @Aal I am not 100% sure on your part numbers here.
The Eagle 60M 275W Panel is a 60 Cell Mono Panel in there standard Eagle Range, the other part number im not sure what you mean.
Do you mean there new AC Panel, which has a micro inverter built in and outputs 240V or did you mean HC, which is a 60Cell Mono Half Cell, which increases conversion efficiency and decreases losses in the panel?
