The 500KW Grid-connect inverter uses digital DSP control and Mitsubishi IPM components from Japan. It features maximum power point tracking to optimize solar panel output, pure sine wave inversion with low harmonics, and islanding protection capabilities. The inverter has robust monitoring, protection, and communication functions including LCD/LED displays, RS485/Ethernet/GPRS for remote data collection and monitoring. It is designed for grid-tied solar systems up to 550KW in size.
