Solax 20kW X3 Pro G2 3-Phase Grid Tie Inverter
The Solax 20kW X3 Pro G2 3-Phase Grid Tie Inverter is a high-performance commercial solar inverter engineered to maximise energy production, improve system efficiency, and deliver reliable grid-connected performance. Designed for commercial buildings, agricultural facilities, warehouses, and large residential installations, the Solax X3 Pro G2 combines advanced inverter technology with intelligent monitoring and robust protection features.
With a maximum PV array input of 30,000W, the Solax inverter supports significant DC oversizing, allowing installers to connect larger solar arrays and maximise energy harvest throughout the day. Featuring two independent MPPTs, an ultra-wide MPPT voltage range, and a low startup voltage, the inverter efficiently tracks solar generation even under changing weather conditions. It also supports 150% PV oversizing and 110% AC overloading output, helping optimise system performance and energy yield.
Designed with safety in mind, the Solax X3 Pro G2 includes Type II surge protection on both the AC and DC sides, an IP66-rated enclosure for outdoor installations, and optional ARC fault protection for enhanced electrical safety. The built-in shadow tracking function further improves energy production where partial shading may occur.
Smart energy management features include built-in export power control, optional intelligent heat pump load management, and 24-hour system monitoring. The inverter also supports multiple communication options, including Pocket WiFi, LAN, and 4G (optional), allowing users to monitor system performance remotely.
With a maximum PV input voltage of 1,100V, 16A maximum DC input current for compatibility with today’s high-power solar panels, and exceptional efficiency of up to 98.5%, the Solax 20kW X3 Pro G2 3-Phase Grid Tie Inverter is an excellent choice for high-performance commercial and industrial solar installations.
