Sungrow Debuts High-Efficiency, Reliable S2500S-L Microinverter at Intersolar South America 2025
Sungrow has introduced its next-generation microinverter, the S2500S-L, to the Brazilian market at Intersolar South America 2025. Designed for superior reliability, efficiency, and ease of use, the S2500S-L aims to accelerate Brazil’s transition to clean energy.
Fast-Track Approval for Brazilian Installations
The S2500S-L delivers 2.5 kW per unit, and connecting three units provides 7.5 kW—compatible with Brazil’s fast-track procedure (Normative Resolution No. 1,000/2021), simplifying technical approval by power distributors. With a power density of 455 W/kg, the microinverter is lightweight yet highly efficient. It supports four independent MPPT inputs with DC currents up to 18 A, ensuring compatibility with a wide range of solar modules.
Built for Extreme Heat
Brazil’s North, Northeast, and Central-West regions experience high temperatures year-round, with microinverters often installed in tight rooftop spaces. The S2500S-L operates reliably at 45°C without power derating and maintains output up to 80°C. Its improved heat dissipation design enhances efficiency by 10–15% over conventional solutions, ensuring consistent performance even in extreme climates.
Simplified, Faster Installation
The S2500S-L features one-click configuration, automatically syncing settings across all devices on the network, reducing setup time by over 66%. Integration with Sungrow’s iSolarCloud platform allows users to monitor real-time power generation, view device health, perform remote diagnostics, and resolve faults quickly, minimizing downtime and maintenance costs.
Robust Communication and Data Management
The microinverter provides strong communication with signal quality 5–10 dB above industry averages and 10% higher transmission power, ensuring long-range, stable connections. High receiver sensitivity (-93 dBm) allows even weak signals to be captured reliably. The system reconnects automatically after short disconnections, and in case of longer outages, it stores data for 24-hour retransmission, ensuring users always have complete and accurate performance records.
Comprehensive Reliability and Durability
Sungrow emphasizes reliability from component selection to testing. Core components undergo tests exceeding 10,000 hours, while total verification surpasses 500,000 hours. The S2500S-L withstands temperatures from -40°C to 125°C, rapid thermal cycling, and features IP67 protection with C5 corrosion resistance. Even after 1,000+ hours of high-temperature, high-humidity, and salt spray testing, it continues to perform flawlessly. It also achieves Class B electromagnetic compatibility, the world-leading home-appliance standard.
With the S2500S-L, Brazilian households benefit from maximum array utilization, high-temperature resilience, enhanced Wi-Fi communication, simplified commissioning, and unmatched reliability and safety. The new microinverter enables efficient, dependable, and easy solar power generation, supporting a smarter, high-quality zero-carbon lifestyle.
