Nowadays the distributed Micro Inverter system for PV (Photo Voltaic) generation is regarded as the one of the effective way for improving the power efficiency. The Micro Inverter system is a distributed system which is composed of PCSs (Power Conversion Systems) on each PV cells. In this paper, we've developed ZigBee network module and monitoring system of the Micro Inverter system for gathering PV generation and PCS conditions. The major packet loss of the wireless network due to the packet collision was reduced by 0.1% during 3,000 times data communication based on 100 ZigBee modules using our new packet protocol. Also we performed the Micro Inverter control and information analysis using our Solar Gateway and web based monitoring server.
