What Is The Function Of Energy Storage Battery?

              (1) Storage power: In most off-grid photovoltaic systems, photovoltaic cells (solar panels) array arrangement of the voltage, current can not be the same as the load (power supply). Especially when the natural conditions change, cloudy, rainy, night light intensity changes, photovoltaic cells can not provide a full load of energy, the result of the use of electrical appliances (load) normal use of difficulties. With storage battery and energy metabolism, photovoltaic system can be used to provide the electrical energy for the electric appliance smoothly and stably. Therefore, it is very necessary to use battery to store energy of PV system.Energy Storage Battery

              (2) regulating voltage (stationary voltage): Because the working characteristics of solar cells are affected by the variation of solar irradiance (irradiation) intensity and temperature, it is very difficult for the solar modules to run under the optimal operating conditions when they are connected directly to the load, so the system efficiency is very low. But when the battery is used as a storage battery, the operating voltage of the solar cell will have "clamp" function, which can be used to charge the storage battery for the solar cell, and to supply the load stably (especially the voltage) to the battery to ensure that the system runs under the best operating condition.Energy Storage Battery

              (3) Provide instantaneous large current discharge: the use of solar photovoltaic systems in the expansion, especially from the grid solar photovoltaic system, into the tens of millions of households will be used as household appliances such as refrigerators (compressors), electric vehicles and motor power, because the start-up of such electromechanical equipment requires a large current, starting with the current is often rated 5,110 times times the operating current. Solar cells in photovoltaic systems are affected by the maximum short-circuit current and the light intensity limit, photovoltaic arrays are difficult to cope with the start-up current requirements, if the application of the battery can provide a large current in the instantaneous load start.Energy Storage Battery
