As the core of a PV plant, the inverter handles DC-AC conversion, power control and on/off-grid transfer. SiC devices and a three-level topology give a peak efficiency of 99.0% or above; a 1000 V AC design cuts line loss and lifts system efficiency by 0.2-0.5%; 5.5 MW sub-arrays optimise the energy path. Grid-forming control supports the grid, with millisecond reactive response, wideband oscillation suppression, high/low voltage ride-through and black start. Anti-islanding, anti-PID, string disconnection and terminal detection are integrated; AI gives string-level fault diagnosis and fan-cleaning life prediction, with APP/Bluetooth service and quick modular replacement.
