Photoelectric Complementary Power System
Detailed introduction
The Photoelectric Complementary Power System is a new kind of power management system with all kind of control function, which is designed to provide energy for a telecom room through solar or from the grid. This system converts energy from solar panels or grid power, or diesel generators, into stable and reliable low-voltage DC power for telecom equipment. The system develops a logic for solar energy usage maximization by coordinating the input from various sources of energy. Surplus energy produced in the batteries during high sunlight hours can be stored and then utilized during periods of low sunlight. When there is not enough solar output, the load can be sustained with grid power and the batteries charged accordingly. If the weather is continuously cloudy and the grid power is not available, the battery discharges to power the load.
Application Scenarios
Base Stations by Telecom Indoors & Outdoors: These may be used for several types of telecom stations, like distributed base stations and telecom rooms.
Off-grid and Hybrid Power Solutions: For regions that don’t have great accessibility to the grid, this is an appropriate power source through solar and other complementary power sources toward reliable and sustainable energy supply.
