How to modify a street lamp powered by solar energy to use 220 volt power supply?

Solar street lights are a kind of lighting equipment that uses solar energy to generate electricity, usually using 12 volts DC power supply. If you need to convert solar street lights to use 220 volt AC power, the following steps are required:

1. Replace the power controller: The power controller of the solar street lamp is usually designed for 12 volts DC power supply, and needs to be replaced with a controller suitable for 220 volts AC power supply. The new power controller should have 220 volts AC input and 12 volts DC output.

2. Replace the battery pack: Solar street lights usually use a 12-volt battery pack to store the electricity generated by solar power for night use. After converting to a 220 volt power supply, you need to replace it with a battery pack suitable for a 220 volt AC power supply.

3. Replace the LED light source: solar street lights usually use low-voltage LED light source for lighting, converted to 220 volt power supply, need to be replaced with the LED light source suitable for 220 volt AC power.

4. Install the adapter: To convert the 220 volt AC power supply to the 12 volt DC power supply for the power controller and LED light source, install the adapter. The adapter can convert high-voltage alternating current into low-voltage direct current to meet the power needs of solar street lights.

5. Circuit modification: After converting the solar street lamp to 220 volt power supply, the circuit needs to be modified accordingly. This includes replacing the power cord, adjusting the circuit connection, etc.

It should be noted that the modification of solar street lights to 220 volt power requires professional operation to ensure that the modification process is safe and reliable. In addition, the modified solar street lights need to be connected to 220 volts AC power to work normally, so there is a need for corresponding power access facilities.
