SPT Series 15–25kW On-Grid PV Inverter
The SPT Series (15–25kW) is a high-performance, three-phase solar inverter designed for medium-scale commercial and industrial PV systems. Built for on-grid applications, it offers exceptional energy efficiency, intelligent MPPT control, and long-lasting durability, making it perfect for medium-sized solar installations. Equipped with dual MPPT trackers, the SPT Series maximizes energy harvest from your solar array—even in partially shaded conditions. Its wide MPPT voltage range (480–850V) and high input voltage (1,100VDC) provide flexibility in system design and allow for oversizing up to 150%. With a peak efficiency of 98.75%, the inverter reduces energy loss and enhances your return on investment. Housed in a rugged IP65-rated enclosure, the SPT inverter is suitable for outdoor installations and operates in extreme conditions, from -30°C to +60°C. It also features built-in USB/RS485 communication and optional WiFi/GPRS modules, enabling seamless remote monitoring and management via a mobile app or PC. Whether you're powering a commercial rooftop, industrial facility, or distributed solar plant, the SPT Series combines advanced technology with robust design to ensure long-term performance, reliability, and energy savings.
