Knox Xerox G4 Pro Series Three-Phase Solar Inverter (5kW–25kW)

Knox Xerox G4 Pro Series Three-Phase Inverters are engineered for superior performance, durability, and intelligent energy management. Designed to support high-power PV arrays up to 38kWp, these inverters deliver stable three-phase output with exceptional efficiency and advanced grid protection.

With dual MPPT technology, the G4 Pro Series maximizes solar harvesting even under uneven panel orientation or partial shading. Its IP66-rated aluminum enclosure ensures reliable outdoor operation in harsh environments, while active cooling maintains optimal performance.

Equipped with advanced protection features, including AFCI, anti-islanding, surge protection, and residual current monitoring, the Xerox G4 Pro Series meets international grid and safety standards. Seamless connectivity via RS485, Wi-Fi, LAN, and optional 4G enables real-time monitoring and easy commissioning through mobile and web apps.

This makes the G4 Pro Series an ideal solution for commercial rooftops, industrial facilities, and large residential solar installations.
