High-efficiency 33 kW three-phase string inverter for commercial and industrial PV systems. Equipped with 3 MPPTs, 1000 V DC input, 98.3% European efficiency, Type II surge protection, smart string monitoring, and IP66 construction for long-term durability.

The SUNGROW SG33CX is a high-performance, three-phase on-grid inverter designed specifically for commercial and industrial (C&I) solar power systems. With a maximum output power of 33 kW and advanced 3 MPPT (Maximum Power Point Tracking) technology, the SG33CX optimizes energy harvest by independently tracking the maximum power point of each solar string. Built to operate with a 1000V DC system voltage, this inverter ensures high efficiency, reliability, and flexibility for medium to large-scale solar installations.

Engineered with robust protection features and a compact design, the SG33CX offers ease of installation and maintenance. Its high power density and excellent conversion efficiency make it an ideal choice for commercial rooftops, industrial plants, and solar farms aiming to maximize return on investment while complying with grid regulations.
