Materials and installation steps of 15W solar street light

1. Determine the position of the vertical lamp and survey the geological situation. If it is 1.2-meter-soil, then the excavation depth should be deepened. At the same time, confirm that there are no other facilities (such as cables, pipes, etc.) below the excavation position, and there is no long-term sunshade on the top of the street light, otherwise, the position should be replaced properly.

2. Reserve 1 m 3 pits that meet the standard at the position where the lamps are erected, and place the embedded parts. The embedded parts are placed in the middle of the square pit, one end of the PVC conduit is placed in the middle of the embedded parts, and the other end is placed in the storage place of the battery. Pay attention to keep the embedded parts, foundation and original ground on the same horizontal plane (or the top of screw and original ground on the same horizontal plane, depending on the needs of the site), one side should be parallel to the road; in this way, the lamp post can be upright without deflection after being erected. Then, C20 concrete shall be poured and fixed. During the pouring process, the vibrating rod shall not be stopped to vibrate to ensure the overall compactness and firmness.

3. After the construction, the residual sludge on the positioning plate shall be cleaned in time, and the impurities on the bolts shall be cleaned with waste oil.

4. In the process of concrete solidification, the concrete shall be watered regularly for maintenance; the chandelier can be installed only when the concrete is completely solidified (generally more than 72 hours). 

(1) Measures shall be taken to avoid short circuit before connecting the output positive and negative poles of the solar panel to the controller;

(2)When the solar cell module is connected with the bracket, it shall be firm and reliable;

(3)The output line of the component shall not be exposed, and shall be firmly tied with a cable tie;

(4)The orientation of the battery assembly shall be toward the south, subject to the direction of the compass. 

After the completion of the above, check the wiring of the controller terminal to prevent short circuit. 

1. Fix the components of each part: fix the sun plate on the sun plate bracket, fix the lamp head on the cantilever, then fix the bracket and the cantilever to the main pole, and lead the connecting wire to the control box.

2. Before lifting the lamp pole, check whether the fasteners of each part are firm, whether the lamp head is installed correctly, and whether the light source works normally. Then, check whether the simple debugging system works normally; release the connecting line of the solar panel on the controller, and the light source works; connect the connecting line of the solar panel, and the light goes out; at the same time, carefully observe the changes of the indicator lights on the controller; only when everything is normal, can it be lifted and installed.

3. When lifting the main light pole, pay attention to safety precautions; the screws shall be tightened. If the sunrise angle of the component is deviated, it is necessary to adjust the sunrise direction of the upper end to the south.

4. Put the battery into the battery box, and connect the connecting wire to the controller according to the technical requirements; connect the battery first, then the load, then the solar panel; during the wiring operation, it must be noted that the wiring and the terminal marked on the controller cannot be connected wrongly, the positive and negative polarity cannot collide, and cannot be connected reversely; otherwise, the controller will be damaged.

5. Debug whether the system works normally; release the connecting line of the sun plate on the controller, and the light will be on; connect the connecting line of the sun plate at the same time, and the light will be off; then carefully observe the change of each indicator light on the controller; if everything is normal, the control box can be sealed.
