to avoid and solve method: first, dc energy saving lamps and dc discharge lamp, etc. , the source of the overall technology already quite mature, and once used in solar system malfunctions, reason is that the solar system is not perfect, the design should be according to the characteristics of different light sources to adapt to and meet the requirements of the use of it, to ensure that the source of real life. Second, improve the battery discharge voltage, which can effectively protect the storage battery, use fixed number of year can be up to 5 years.
