Product Description:
Mppt/pwm 80a/100a 12V 24V 36V 48V solar panel automatic charging controller
Note: whether mppt+pwm solar controller is compatible, non MPPT 100% true
The controller is automatic 12/24/36/48v, but the voltage of photovoltaic panels used to charge different batteries is different. For 12V batteries, use about 18V photovoltaic panels; For 24V batteries, use photovoltaic panels of about 30-37v; For 48V batteries, use 60. For photovoltaic panels of approximately -72v, the wiring of the controller is first connected to the battery and then to the photovoltaic panel. On the contrary, disconnect the cable, otherwise it will easily damage the controller!
(3) Description of load protection
When using 12V battery, the battery charging voltage is 13.7 v
When 24V battery is used, the battery charging voltage is 27.4 v
When using 36V battery, the battery charging voltage is 41.1 v
When 48V battery is used, the battery charging voltage is 54.8 v
Note: first connect the battery to the controller, and then connect it to the photovoltaic panel to ensure that the battery voltage is greater than (12V battery is greater than 10V; 24V battery is greater than 20V; 36V battery is greater than 30V; 48V battery is greater than 40V), otherwise voltage identification error will be caused.
(4) Clock setting instructions: when the battery is connected, press "" "to set the clock, and briefly press" "to save.
(5) Charging voltage setting instructions: after connecting the battery, set the clock and save it, press and hold "" for 3-5 seconds, and the screen displays l**v as floating charging voltage, which can be adjusted by pressing ""; Briefly press "" H again ×× V increase the charging voltage, and press "" to adjust; Briefly press "" again. F**v is the low-voltage cut-off voltage of DC load, which can be adjusted by pressing ""; After setting, press and hold "" for 3-5 seconds to save and exit.
