Abstract: A distributed photovoltaic system includes N first photovoltaic modules each configured to convert solar energy into direct current power, N energy storage modules, and N inverters. Output terminals of the N first photovoltaic modules are connected to input terminals of the N energy storage modules in one-to-one correspondence. Output terminals of the N energy storage modules are connected to first input terminals of the N inverters in one-to-one correspondence. Output terminals of the N inverters are connected in parallel at a joint connected to a power grid or load. That is, a single energy storage module is connected to a single photovoltaic module and a single inverter, so that the single energy storage module is small in capacity and low in power. In addition, different energy storage modules are scattered.
