Installation Method: 4 x m screw Wiring Method: Terminal IN is input and OUT is output Module Size: Approx. 60 x 31 x 22mm / 2.4 x 1.2 x 0.9in(without header) Charging Indication: red light when charging, green light when full. The detection method of the turn signal is current. When using solar panels to supply power, the solar hour charging current is also small, lower than the turning current, and will also light green, but it is not full at this time, please pay attention to distinguish. Using a live meter will see the charging current more directly Package List: 1 x Step Down Module Note: <b Package List 1 x Step Down Module
