A design method of photovoltaic power communication management system based on SoC FPGA is introduced in this paper. The system uses the new-type SoC FPGA integrated with ARM hardcore process as its main control chip, which divides the work of operation and communication of traditional communication management unit reasonably and is implemented by FPGA and ARM processor. By adopting the design of combining hardware with software, this system can simplify the circuit design, reduce the number of CPU interrupts for communication transactions, increase the total number of RS485 ports which support MODBUS protocol，and the system is recoverable in a disaster situation through the independent NIOS II backup system, etc, so it is more suitable for the application of multiple devices and massive data in photovoltaic power system.
