Connect the connecting wires of the solar cell module according to the system voltage of the solar street light and the voltage of the solar cell module. If the system voltage of the solar LED street light is 24V and the voltage of the solar cell module is 17V or 18V, the solar cell modules should be connected in series, and the series connection method is the positive level (or negative level) of the first module and the second module Negative (or positive) connection. If the voltage of the solar cell module is 34V, the solar cell module should be connected in parallel. The method of parallel connection is to connect the positive and negative poles of the first module and the positive and negative poles of the second module correspondingly. When wiring, use a small flat-blade screwdriver to open the solar cell module junction box, and crimp the power cord of the solar cell module to the terminal block of the junction box. After the wires are connected, fasten the waterproof nut on the outlet end of the junction box, and apply 7091 sealing silicone to the terminal in the junction box. The amount of glue applied is so that the inlet hole in the junction box is completely sealed. Then fasten the junction box cover, the junction box cover should be fastened, not reversed.
