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

specially used for solar garden light distribution system of light volt battery may not apply. Only by understanding its characteristics, adjust measures to local conditions, reasonable use, 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. Photovoltaic systems, however, is geared to the needs of the efficiency of the system, the efficiency is proportional to the battery life. Battery in the photovoltaic system working condition is different from the power grid of battery working conditions. Manufacturers of battery parameters are for reference only. Photovoltaic system adopts distribution way to make the normal operation of power rating load, and the battery in the photovoltaic (pv) power distribution system plays a multiple role. For photovoltaic (pv) matrix and grid power, storage battery can be seen as a load cell, and to load, battery is a power battery. In a photovoltaic system, battery balance energy and stored energy. In addition, the battery in limiting the maximum power output of photovoltaic (pv) matrix plays an important role. Lead-acid batteries are mainly used for photovoltaic system. Traditional technical indexes of this type of battery is mainly in order to adapt to the commercial application of power system. As a common emergency power supply, the key requirement is floating storage, maintenance, performance and longevity. As a motor vehicle, it needs large current discharge and cycle time. Photovoltaic power generation system used in the battery not only consider the service life of the generation and maintenance and performance, and due to the high cost of photovoltaic power generation, need efficient on the performance of the battery charging and discharging. In the 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 efficiency features not only is the only fixed parameters, different battery and battery dynamic performance under different conditions of use. The efficiency of the new and old battery are different. Although different battery efficiency difference is very big, but the same battery may also make the battery when floating and large current discharge in the inefficient state. Therefore, if you don't know don't provide the product efficiency performance of the battery working state of the product and the important parts of important features, it is absolutely impossible to design a reasonable photovoltaic system. Engaged in the photovoltaic system engineering research people do everything possible to avoid using battery reason is they don't know what effect will bring system. Facts have proved that their concern is very reasonable, but the problem that all battery of photovoltaic systems, grid inverter system or independent system of street lamp, are caused by the battery. In addition, in a photovoltaic system, floating life for up to 20 years of battery scrap are not rare in a year.
