Solar Battery maintenance-free solar battery 12V100AH ??wholesale characteristics: ⑴ long life: good corrosion resistance made of special lead-calcium alloy plates, may have a long float life; the amount of acid solar battery using a special liquid, adding, prevent electro-hydraulic stratification and prevent short-circuiting crystal plate support to ensure long battery life. Solar cells are the basis of VRLA battery technology to achieve a longer life on. So 12V series solar cell design life of 6-8 years (25 ℃); 2V series solar cell design life of 10 to 15 years (25 ℃). ⑵ less self-discharge: use of special lead-calcium alloy grid, will limit the amount of self-discharge to a minimum, long-term preservation. ? ⑶ easy to maintain: As the float charging, most of the oxygen inside the battery electrolyte is absorbed reduced to the cathode plate, virtually no reduction in the electrolytic solution, so do not have as a general measure, as the battery electrolyte specific gravity and replenishment. ? ⑷ Installation is simple: the battery vertical, lateral installation can be, without the risk of fluid leakage of electricity, but also in the normal process of charging the battery will not produce acid mist. Therefore, the battery can be installed in an office or equipment room, without separate special battery housing construction, reduce project cost. ? ⑸ Safety: To prevent excessive gas, the battery is equipped with a safety valve. In addition, also equipped with explosion-proof filter, even if there is a spark in the structure close to the battery can also keep from getting inside. ? ⑹ easy to use: when the factory is fully charged battery, the user can get the battery installed and put into use. Solar Battery - Introduction ?????? solar battery is the 'battery' application in the solar photovoltaic power generation, the currently used lead-acid maintenance-free batteries, ordinary lead-acid batteries, gel batteries and nickel-cadmium alkaline storage battery four. ? China is currently the solar batteries are widely used mainly: maintenance-free lead-acid batteries and gel batteries, these two types of batteries, because of its inherent "free" maintenance features and characteristics of less polluting to the environment, it is suitable for reliable performance The solar power system, especially unattended workstations. ? ???? Ordinary lead-acid batteries due to the need for frequent maintenance and greater environmental pollution, so the main adapted to have the ability to maintain or low-grade occasions. ?? ???? Alkaline nickel-cadmium batteries, although there is a good low-temperature, over charge, over discharge performance, but because of its high price, only applies to more special occasions. ?? With the widespread use of solar photovoltaic power generation system, as its support of the battery is also more and more people's attention. ? Solar Battery - should have the following characteristics a good deep cycling capability, with good overcharge and over discharge capacity?. ?? 2? Long life, a special process design and gel electrolyte to ensure a long-life battery. ?? 3? Apply different environmental requirements, such as high altitude, high temperature, low temperature and other conditions of normal use different battery. ? Solar Battery - works during the day the sun light shines on the solar modules, the solar cell module to generate a certain level of DC voltage, the energy is converted to electrical energy, and transmits it to the intelligent controller, intelligent controller after overcharge protection, will Solar power transmission components came to the battery for storage; and stored on the need for batteries, so-called battery that is stored chemical energy and emit an electrical energy chemical equipment if necessary. ?? Constitute the main component of lead-acid batteries as follows: ?? anode plate ---> ?? cathode active material board -? (Lead peroxide PbO2??.??)?? (Spongy lead .Pb??)? -?> ?? electrolyte active material ---> sulfuric acid (H2SO4?) + water (H2O?) ??? (sulfuric acid??)??????
