Today, with the development of urban construction, the investment in solar street lights is also increasing. In my country, the use of solar street lights saves a lot of electricity every day. In many remote areas, there are problems with power generation or transmission, and maintenance costs are high, so solar street lights play a vital role. Solar street lights will not cause electric shock, fire and other accidents, and are easy to install. It facilitates life in remote areas. So, what are the main modes of solar street lights?
1. Excavating the ground structure does not require wiring or "open voltage", and there is no power failure and power limitation. Answer: The voltage at the control point is balanced. After direct charging, the battery will be left for a period of time by the charge and discharge controller, and the battery will be fully charged, that is, "balanced charge". The charging time should not be too long, usually only a few minutes to ten minutes. Too long and too harmful. For a small system with two batteries, it doesn't make much sense.
Second, the life of the solar cell is related to its daily discharge. If the light is turned on or off every day, the daily capacity of the battery is not large, and the battery tends to have excessive discharge, the edge is too small, and gradually empty, which affects the service life of the battery.
3. In order to reduce the price of solar street lights, the solar street lights are set to automatic mode, and there is no configuration required for night lighting, so the price of the whole set of solar street lights is reduced.
Fourth, the over-discharge protection terminal voltage, the 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 not difficult to see from the above content that solar street lights have no power failure and power limit, over-discharge protection terminal voltage, battery discharge can not be lower than the national standard, and solar battery life has a certain relationship with its daily discharge.
