Smart MPPT 50A 60A 80A 100A Sun Solar Charge Controller high input voltage AUTO 12V 24V 48V PWM for Lithium Lead Acid Battery

Major functions:
The controller is 12/24/36/48V auto, but the voltage of the photovoltaic panels used to charge different batteries is different. For 12V batteries, use about 18V photovoltaic panels, for 24v batteries, use about 30-37V photovoltaic panels, and for 48V batteries use 60. For photovoltaic panels around -72V, the controller wiring is connected to the battery first, and then to the photovoltaic panel. Disconnect the wire on the contrary, otherwise it will easily cause damage to the controller.
Description of charging protection:
*When using a 12V battery, the boost charging voltage of the battery is higher than 14.8V, and it is converted to a floating charging voltage of 13.8V.
*When using a 24V battery, the battery boost charging voltage is higher than 29.6V, and it changes to a float charging voltage of 27.6V.
*When using a 36V battery, the battery boost charging voltage is higher than 44.4V, and it changes to a floating charging voltage of 41.4V.
*When using a 48V battery, the battery boost charging voltage is higher than 59.2V, and it changes to a floating charging voltage of 55.2V.
Note: Please connect the battery to the controller first, and then the photovoltaic panel to ensure that the battery voltage is higher than (12V battery is higher than 10V; 24V battery is higher than 20V; 36V battery is higher than 30V; 48V battery is higher than 40V), otherwise it will cause voltage Identification error.
