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.
