50kw solar inverter

50kw solar grid tie inverter Technical Features: Adopt U.S TI company control DSP chip. Using Mitsubishi or Infineon company IGBT module to improve the reliabity. MPPT(Maxium Power Point Tracking)Technology. With a manually input DC breaking switch,manually breaking switch from AC power grid . With advanced anti-island inspection scheme and perfect monitoring function. With overload,short circuit,abnormal grid protection,and alarm fuctions. Wide input DC range,the efficiency up to 98%. Adapt large grid voltage fluctuation characteristics,normal working of the grid connected inverter allows voltage range of threephasekine voltage:350VAC 430VAC,Frequency range:47 51.5Hz. User-friendly operation interface,English menu,can display the operationg data,real-time fault data,historical fault data,and the status of equipment. Can provide including RS485/RS232 or Ethernet remote communication interface.RS485 follow the Modbus communication protocol;Ethernet interface support TCP/IP protocol,support to obtain dynamic(DHCP) or static IP address.
