Considering wire voltage drops in PV panels and lower panel voltages during cloudy\/rainy conditions, the open-circuit voltage of PV panels must exceed the 18V input when charging 12V batteries. 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\/p\u003e\u003cp\u003eCommissioning Procedure\u003c\/p\u003e\u003cp\u003e1. Connect 16V-80V PV panel input (overvoltage prohibited; observe polarity). Correct wiring activates power indicator. If output indicator illuminates, proceed directly to Step 3.\u003c\/p\u003e\u003cp\u003e2. If the power indicator lights up after input connection but no output voltage is present, first adjust the MPPT potentiometer counterclockwise until voltage output appears and the output indicator lights up.\u003c\/p\u003e\u003cp\u003e3. For charging a 12V battery, set output to 14.2V; for a 24V battery, set to 28.4V; for a 48V battery, set to 56V.\u003c\/p\u003e\u003cp\u003e4. Connect the battery and use a multimeter to test the input voltage. Adjust the MPPT potentiometer until the input voltage equals the maximum power point voltage (MPP voltage) of the PV panel (i.e., the PV panel's 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. Specifications vary by panel type; refer to the default factory parameters labeled on the panel's back.\u003c\/p\u003e\u003cp\u003eSet the output voltage to 14.2V and output current to 20A. Adjustable range: 1-20A. Set the MPPT voltage to 17V.\u003c\/p\u003e\u003cp\u003ePackage Contents\u003c\/p\u003e\u003cp\u003eModule*1\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003ch4\u003eQ: What is the 800W 25A MPPT Solar Charger Power Supply Module 18V-90V?\u003c\/h4\u003e\u003cp\u003eA: The 800W 25A MPPT Solar Charger Power Supply Module 18V-90V is a quality decor pick.
