Abstract:
    This invention relates to a control method for storage cells used in photovoltaic merging system including solar systems from the first path to n path, in which, each path system includes a photovoltaic array, the output of which is connected with a charge circuit, the output of which is connected with a storage cell, a sample circuit is set to be connected to a load, the CPU process unit controls the charge circuits from 1 to n, a voltage current double closed loop is applied to carry out parallel control with PRI, when the voltage or current of the cell reaches to the threshold, solar energy input of certain paths is cut off/closed one by one, and when the voltage or current of the cell reaches to the maxium or minimum threshold, all of them are cut off/closed.
