The main function of the controller is to sample the voltage of the battery and solar cells. Timely voltage collection and A/D conversion of batteries and solar cells are completed through voltage sampling circuits.

Charging and discharging control of solar batteries. The microcontroller compares the sampled voltage with the set voltage, announces the corresponding control based on the comparison results, and completes the charging and discharging control of the battery. Active switching control between battery powered and mains powered.

Compare the collected battery voltage Vcx with the battery discharge maintenance voltage VoXmn, and the corresponding port of the microcontroller announces the operation of the battery power supply switching circuit to complete the active operation of the solar battery power supply switching circuit.

The installation address of solar street lamp manufacturers should be selected from four weeks for drainage. If there are 10 meters, the water pit and river within the radius of the river and water pit must be 2 meters below the ground; There are no items around (based on the lighting of the device) and the risk of high voltage lines; Underground cables, optical cables, sewers, and other public facilities without installation addresses.

According to the construction site, the construction team can select non rational X and suspend construction, and report the device location to the relevant personnel at the time. The tools required for the preparation of solar street lights and the selection of construction personnel before construction; Strictly follow the selection of cement according to the solar street lamp fund plan, and use acid and alkali cement for soil with high pH values;

Impurities such as soil in sand and gravel shall not affect the degree of concrete; Strictly follow the size of solar street lamps (constructed by construction workers) in accordance with the fund plan, and excavate the foundation pit along the way; After the excavation of the pit is completed, check for groundwater seepage.

If groundwater leaks, construction should be suspended; The bottom of the battery compartment must be added to the drainage hole 5 at the bottom ×Ф 80 or based on the attached drawings. The upper surface of the embedded cage must be horizontal (measured and checked with a level gauge), and the cage must be perpendicular to the surface of the anchor bolt's base.
