Pure Sine Wave Inverter Rear Stage Board 4000W–5000W | DC 320–450V to AC 110–220V

Pure Sine Wave Inverter Output Stage Board (4000W–5000W)

This high-power inverter rear stage board converts high-voltage DC (320–450 V) into a stable pure-sine AC output (110 V / 220 V). Designed for integration with front-end boost converters or solar DC buses, it delivers reliable AC power for home, industrial, and experimental systems.
