2X PWM 100A 12V 24V 36V 48V AUTO Solar Panel Charge Controller Solar PV Battery Charger with LCD MPPT Solar 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: connect the battery to the controller first and then the photovoltaic panel to 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.
