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)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 26px;\"\u003e\u003cstrong\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif;\"\u003eCommissioning Procedure\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 20px;\"\u003e1.

Connect the battery and test the input voltage with a multimeter. Adjust the MPPT potentiometer to match the input voltage to the PV panel's maximum power point voltage (i.e., operating voltage). For an 18V PV panel, the open-circuit voltage of a single string is approximately 21V, with an operating voltage of 18V. For a 36V PV panel, the open-circuit voltage of a single string is approximately 43V, with an operating voltage of 36V. For a 43V solar panel, the open-circuit voltage of a single string is approximately 49V, with an operating voltage of 43V.
