SPS Series 3–6kW On-Grid PV Inverter
EPEVER’s SPS Series 3–6kW single-phase on-grid inverters deliver reliable and high-efficiency power conversion for residential solar systems. With advanced dual MPPT technology, support for 150% PV oversizing, and natural cooling design, the SPS Series ensures optimal energy production under various conditions. The inverters feature a compact structure, quiet operation, and are ideal for rooftop installations. Engineered with IP65 protection and robust internal safeguards, these single-phase string inverters offer long-lasting outdoor performance. They accommodate a maximum PV input voltage of 600V and operate efficiently across a wide MPPT voltage range of 70V to 550V. Smart monitoring is available via USB, with optional WiFi and GPRS modules for real-time system tracking through the Solar Guardian App. The SPS Series is designed for seamless integration into different residential grid environments, supporting a rated output voltage of 230V and flexible power outputs from 3kW to 6kW. With a maximum efficiency of 97.9%, strong protection features, and intelligent communication options, it provides a reliable foundation for modern residential solar energy projects.
