①Remaining energy storage and backup: the storage of photovoltaic energy beyond the load demand, the output of energy when the photovoltaic is weak; the battery will retain the excess electricity generated by the system when the sun is sufficient, and use it at night or in rainy days without wind. Solved the problem of inconsistent time between power generation and power consumption. ②Ensure the stable power output of the system: Eliminate the fluctuation of photovoltaic input power and the difference with the load demand. The working period and power of various electrical equipment have their own changing laws, and it is impossible to naturally cooperate with the solar energy and the electrical load. The large storage space and good charging and discharging performance of the battery provide favorable conditions for the adjustment of the power and energy of the photovoltaic power generation system. ③Improve power quality and reliability: provide instantaneous energy when voltage fluctuates, flickers, and falls. There are often productive loads in photovoltaic village systems. These loads are not only large in capacity, but also generate inrush current and inrush current during startup and operation, such as water pumps, lawn mowers and refrigerators. The low internal resistance and good performance characteristics of the battery can meet the requirements of the above-mentioned inductive load on the power supply.
