12 v solar street lamps light only 4 seconds

Solar garden light distribution system for battery is not always suitable for application in photovoltaic system. Good quality battery only after knowing its features, design of adjust measures to local conditions, reasonable use, to meet the design requirements. Due to the battery performance each

solar garden light distribution system battery is not always applicable light system. Only by understanding its characteristics, design scheme according to local conditions and rational use of high quality batteries can meet the design requirements. Due to the different performance of the battery, could not have the unification of the photovoltaic system design method is given. However, photovoltaic (pv) system is a focus on the efficiency of the system, the efficiency is proportional to the battery life. Battery in the photovoltaic system in different working conditions and the power grid, so manufacturers battery parameters are for reference only. Photovoltaic system adopts distribution power supply mode, make the rated power load can run normally, the role of accumulator in photovoltaic (pv) power distribution system is multiple. For photovoltaic (pv) matrix and the grid power supply, battery can be thought of as the load components, for the load, battery is the power components. Battery balance power and store energy in the photovoltaic system. In addition, the battery in limiting the maximum power output of photovoltaic (pv) matrix plays an important role. Photovoltaic (pv) system used in most of the battery is lead-acid batteries. The battery indicator system of the traditional technology is designed to adapt to application in the commercial power system. As a common emergency power supply, the key requirement is that energy storage, maintenance, performance and floating life. As motor vehicles, it requires high current discharge and recycled. In addition to consider service life, power generation, and the performance such as maintenance, photovoltaic power generation system used in batteries due to the high cost of photovoltaic power generation, need efficient charge and discharge. In a high efficient photovoltaic system, battery efficiency determines the efficiency of the system. However, almost all the battery supplier did not provide the efficiency of its product features. Battery characteristics is not only the efficiency of different unique fixed parameter, is also a dynamic performance of battery is used in different conditions. The efficiency of the new and old battery are different. Despite the different battery efficiency difference is very big, but when in high electric floating down and discharge, the same battery may in the inefficient state. Therefore, if you don't know the working state of the photovoltaic battery products in the system and the important components of important features, it is impossible to design a reasonable photovoltaic system. Engaged in the photovoltaic system engineering research people try to avoid using battery because they don't know what effect will bring system. Facts have proved that their worry is reasonable, but all the battery of the photovoltaic system, grid inverter system or independent system of street lamp, are caused by the battery. In addition, it is obviously a floating life of 20 years of battery, in a photovoltaic system, scrap is not uncommon in a year.
