1. Safety Instructions
Please save these instructions
1.Read all of the instructions and cautions in the manual before
installation.
2.There are no repairable parts for this controller,do not disassemble
or attempt to repair the controller.
3.Keep the controller from the water.
4.Make sure all connections with controller are tight.
5.Please read the product installation steps to ensure all connections
are correct.
Please follow the safety instructions for operation, the damage caused
by not following the safety instructions shall be borne by the individual.
1-1.General Safety Information
1.NEVER connect the solar panel array to the controller without a
battery. The battery must be connected first.
2.Ensure input voltage does not exceed 100 Voc to prevent permanent
damage.
3.Ensure that the output current of the solar panel does not exceed
the rated charging current of the controller.
1-2.Charge Controller Safety
1 . Do not let the positive (+) and negative (-) terminals of the battery
touch each other.
2. Explosive battery gases may be present while charging. Be certain
there is enough ventilation to release the gases.
3. Be careful when working with large lead-acid batteries. Wear
goggles and have fresh water available in case there is contact with
the battery acid.
4. Over-charging and excessive gas precipitation may damage the
battery plates and activate material shedding on them. Too high of an
equalizing charge or too long of one may cause damage. Please
carefully review the specific requirements of the battery used in the
system.

1. The positive and negative poles of the battery must be connected
to the battery terminals of the controller first.
2. Finally, connect the positive and negative poles of the solar panel to
the PV terminals of the controller.
3.Make sure that the Bluetooth of the mobile phone is turned on, and
open the APP "Solar" to enter the setting interface.
