regulator controller20A 12/24V fotovoltaic ( solar )

Function: . Always keep the battery on fill voltage condition. . Prevent the battery from over-charging. . Prevent the battery from over-discharging. . Prevent the battery from reverse charging to solar panels during nights. . Reverse Polarity Protection for Battery . Reverse Polarity Protection for Solar Panels . When the battery voltage is low, the controller will automatically cut off the load from the system. If the voltage of battery is back to normal and the load will restart working. . Thunder protection . According to the battery voltage grade, the controller can automatically set charge-off voltage, the load-off voltage, the load- restore voltage. (The parameter is default under 25?condition, locked by the CPU procedure, cannot adjust.)

. The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.

As shown in the following diagram of connection, there are 6 terminals on the controller with clear sign.

Warning: Before connecting to the solar panel, please connect the controller to the battery; do not use solar panel supply power to the loads directly. Notes: Do not use lamplight to charge the solar panel (lamplight is too weak to charge) DC power source to replace the solar panel will cause troubles to controller.

Choose the suitable wire which diameter should not be too small, please refer to the parameter.

1. . When Red LED (CHARGE) is on, battery is charged up strongly; When Red LED is flickering, battery is MPPT charged up in constant voltage; when Red LED is oft charge off . When Green LED (LOAD) is on, loads are working; when Green LED (LOAD) is off, loads stop working. . Three Color-changing LED (BATTERY), When light is red, it indicates low voltage, green indicate battery full charged, orange indicate normal status.

Color-changing LED working voltage indicates area:

Phenomenon: Green LED off, battery indicator LED is red.

Reason: Low voltage of battery

Solution:

A: Cut off the power, disconnect the load; reconnect the load after the charge become normal.

B: Battery charge problem: Increase the solar panel power or change the battery.

Phenomenon: Battery indicator LED is orange and Load indicator LED is green, the loads cannot work. Reason: Over load or short-circuit causes the controller inner fuse cut off

Solution: 10-20 minutes after eliminated the malfunction, the fuse will automatically back to working.
