專利摘要：
The present invention relates to an inverter system for energy-storing microgrid and a controlling method thereof, wherein the inverter system for energy-storing microgrid is integrated with a detecting module, a controlling and processing module, a visual resistor algorithmic processor, and a PWM signal generator. Moreover, the controlling and processing module is installed with a power-voltage reducing function and a reactive power-frequency reducing function for making the controlling and processing module be able to properly distribute the intensity and output ratio of all the output currents of the inverters according to the charge states of battery modules and load currents. Therefore, the current supply of each of the parallel connected inverters in the inverter system can be automatically distributed and modulated for effectively providing necessary electric power to each of connected loads, respectively.
