Nowadays, with the development of urban construction, the investment in solar street lights is also increasing. In our country, the use of solar street lights saves a lot of electricity every day. In many remote areas, where there are problems with power generation or transmission and high maintenance costs, solar street lights play a vital role. Solar street lights are not subject to accidents such as electric shock and fire and are easy to install. It facilitates the life in remote areas. So, what are some of the main modes of solar street lights?
A. Digging ground structure does not need wiring or "open voltage", no power outage and power limitation.
A: The voltage of the control point is balanced. After direct charging, the battery will be rested by the charge/discharge controller for a period of time, and the battery will be fully charged, i.e. "balanced charging". The charge time should not be too long, usually only a few minutes to ten minutes. The set time is too long and harmful. For a small system with two batteries, it does not make sense.
Second, the life of a solar cell is related to its daily discharge. If the light is on or off every day, the daily capacity of the battery is not very large, the battery tends to have too much discharge, the edge is too small and gradually empty, affecting the life of the battery.
Third, in order to reduce the price of solar street lights, solar street lights are set to automatic mode, there is no configuration required for night lighting, thus reducing the price of the whole set of solar street lights.
Fourth, over-discharge protection end voltage, battery discharge can not be lower than the national standard, although the battery manufacturer also has its own protection parameters, but ultimately close to the national standard.
It is easy to see through the above, solar street lights without power failure and power limit, over discharge protection end voltage, battery discharge can not be lower than the national standard, solar battery life with its daily discharge has a certain relationship.
