APOLLO G-530/ APOLLO GTP-530 series is high performance single-phase/three-phase grid connected central inverter that controlled the operation by microprocessor. With this high efficiency microprocessor, the inverters have capability to check electrical environment accurately and feedback the data to control itself in order to produce the proper solution for user such as display the electrical data both PV module side and utility line side, record power generated in each day and total generated power, record electrical data for past 180 days. This type of grid connected or grid tie inverter integrates with MPPT (Maximum Power Point Tracking) algorithm to extract the maximum power generated by PV array, and also protection system for reverse power to utility line. These grid connected inverters are suitable for grid connected solar power system or solar grid tie system for residence, building, store or factory.
