1. What is the scenery complementary street lights

Scenery complementary street lights are a new type of energy -saving street lights, which are composed of components such as Solar cell panels, wind power generators, wind -complementary street light controllers, batteries, and LED light sources.When the user needs to use electricity, the inverter transforms the DC electricity stored in the battery pack into AC power. It can not only reduce the dependence of conventional electricity through the transmission line to the user load at the user load, but also provides new rural lighting to provide new rural lighting.Solution.

2. What are the working principles of the scenery complementary street lighting system

Scenic complementary power generation system is a device that converts wind energy and light energy into electrical energy.The rectification and voltage of the device convert the AC power to DC power, charge and store the power of the battery pack.

The Solar panel uses the most conversion rate of the most conversion rate of single crystal silicon Solar panels. The photovoltaic effect is used to directly convert the solar energy into DC electricity. When the wind energy resources are insufficient, it can be used for load use or stored in the battery for later use.
