APOLLO G-330 series is high performance three-phase grid connected inverter or grid tie inverter and controlled the operation by microprocessor. With this high efficiency microprocessor, the inverter has capability to check electrical status accurately and feedback the data to control itself in order to produce the proper solution for user. Moreover, it can display the electrical data of each inverter remotely by transfer data via RS-485 port and able to select to display the electrical data on LCD display of Central Monitoring Unit (CMU) or to display the solar radiation and temperature data on LCD display of Data Acquisition Unit (DAU). And also, works with Apollo View software by connecting to the computer to transfer the system data to display on computer. This grid connected inverter is suitable for grid connected solar power system or solar grid tie system for residence, building, store or factory.
