1. The fixing components of each part of 28w 3port solar charger fix solar panels, solar panels, lamp holders to fix the arm, then pick up the bracket arm and the fixed main pole, and insert the cable into the control box and battery box;

2. Pay attention to safety precautions for the lifting rod, the screw is absolutely good, the wrong view of the component, such as: the angle toward the sun, and finally the south direction needs to be adjusted;

3. Before lifting the boom, check whether the fasteners are strong parts, and the lamps are installed correctly, regardless of normal light work. The simple debugging system normally releases the solar panel on the control cable; the cable is connected to the solar panel, and the controller carefully observes the changes of the indicators at the same time, all belong to the normal installation before lifting;

4. Put the battery into the battery box and connect it to the controller in accordance with the connection line. The technical requirement that the battery can withstand the load, and then the solar panel used must be paid attention to when connecting to the controller. There should be no mistakes on each terminal. In the collision of the negative poles, the wrong connection should not be adopted, otherwise the controller will be damaged.

5. Debug the system normally, release the control cable, connect the cable to the solar panel, and the controller carefully observe the changes in the indicators at the same time. Before closing the control box, test it completely to avoid other failures.
