Outdoor LED Solar Street Light User & Installation Manual
This article is about Outdoor LED Solar Street Light User & Installation Manual, written by the experienced engineer of Yangfa company, and it will teach you how to install your Solar Street Light professionally.
We use a real project as a case:

Flux > 2800 LM Color Temperature 4200k
Battery 100Ah maintenance free lead acid Controller SRNE brand smart LED controller
Working voltage 12 V
Working time 8 hrs per day
Autonomy 3 days of no charge (rainy /cloudy days) Height 3 Meters
1.1 The first step is to choose an appropriate installation site, keeping in mind that there are no electric wires or water pipes running underground. It should also be noted that trees near the installation site can cast a shadow on the solar panel and can reduce the output power. Top portion of the street light should be completely free for direct access to sunlight.
1.2 As shown in diagram below, a one cubic meter hole is required for the installation of the street light. Begin pouring concrete in the hole and embed the bottom portion of the pole in the center. Place one end of PVC pipe in the center of the pole base, and the other end at the installation position of storage battery (as shown in the diagram below). Make sure the top of the embedded part, the concrete foundation and the original ground are leveled with each other (or depending on the site requirements, keep the top portion of the bolts and original ground at the same level). One edge of the foundation should be parallel to the street in order to keep the light pole stand straight. Then secure it in place using C20 concrete. VERY IMPORTANT: During the pouring process, operator should use vibrator continuously to assure the compactness of the base.
1.3 Water should be poured on concrete regularly during its solidification process. Proceed with the installation after the concrete solidifies completely (generally takes more than 7 days).
2.1 Insert a 1.5 mm2 twisted wire into the opening of the light arm, then into the light pole through the hole at the top of pole. Continue until the wire reaches the bottom of the light pole. One end of the twisted wire should connect to the storage battery, and the other end should connect to the controller. Afterwards, attach/bolt the arm onto the light pole according to the specific position requirements.
2.2 Insert two 4.0mm2 copper cores through the bottom of the light pole (red one connects to the positive terminal, blue one connects to the negative terminal), and bring them out from the top of the light pole. Connect one end of the core to solar module, and the other end to the controller.
3.Install Luminaire (light fixture)
3.1 Connect twisted wire to the input lines of luminaire (Red is positive terminal).
3.2 Secure luminaire onto the arm using screws.
4.Install Solar Panel
4.1 Connect the Panel support to the loop with bolts, and then connect the solar panel onto the support. Take the necessary measures for avoiding short circuit before connecting output terminals of solar panel to controller.
4.2 Connect the output lines of solar panel to the copper cores that were threaded out from the light pole (N.B. red should connect to the positive terminal)
4.3 Connect the solar panel support onto the light pole; all modules should face south (refer to compass).
5.Setup Light Pole
5.1 Before lifting the light pole, make sure that each part is securely fastened. Check the installation of light holder and the luminaire that they are functioning properly. Perform small tests to make sure that the modules are also functioning properly (disconnect wires of solar module in the controller, lights should turn on; connect the wires of solar module in the controller, light should turn off. Meanwhile, examine the changes of indicator lights on the controller carefully. Start lifting and installing after examination.
5.2 As shown in the picture, pull the light pole using manpower or crane, thread all cables out from the bottom of light
pole, and then fix the pole onto the embedded part (base of the pole).
5.3 During the process of lifting, pay attention to safety. Make sure the screws/bolts are tightened properly, the angle of module should be precise, use compass to make sure the module face south.
6.Install Storage Battery
Connect lines to the positive and negative poles of storage battery, and then thread those lines through PVC pipe to the light pole. After that, put the storage battery in the box underground, cover it with cement plate, or fill it with soil and then smooth the surface or cover it with concrete slab.
Preventive measures: On the top of the concrete slab, cover the surface with bricks. Then fix it with plug bolt, and weld
the nut shut.
Connect the wires to the controller according to the drawing below. First connect the storage battery, then connect loads, finally connect solar panel. Pay special attention when connecting the wires of controller and other circuits. Do
not connect negative wire to positive, doing so can cause damage to the controller.
Test the system to see if all of the modules are functioning properly: Disconnect the wires of solar module in the controller, lights should turn on; connect the wires, light should turn off. Meanwhile, examine the changes of indicator lights on the controller carefully and after that seal the controller box.
During installation keep the following things in mind:
- 1. The energy source of “solar street lights” is sun light, make sure the PV modules are exposed to the sun light at all times and there is no shade causing trees or tall building nearby.
- 2. When threading, make sure the wires do not get caught in the joint of light po Joints of the wires should be covered with PVC tape.
- 3. In order to maintain the appearance and performance of the solar panels, clean the dust on the solar modules every
6 months, but do not wash it from top to bottom with water.
