This power module is a buck controller. Considering wire voltage drops in PV panels and lower panel voltages during cloudy/rainy conditions, charging a 12V battery requires PV panel open-circuit voltage exceeding 18V input. For example: - 18V panels: 2 panels in series (e.g., 18V-72V for 12V charging) - 42V panels: 2 panels in series (e.g., 42V-80V for 24V charging)
