One-click configuration: commissioning is simplified by synchronizing multiple microinverters via the iSolarCloud app, reducing field time and minimizing rework.
Operating at 45°C without power derating and maintaining reliable output up to 80°C.
Transmission power is increased by 10%, enabling a stronger and longer signal reach.
Providing 24-hour data retransmission: generated data is securely stored and automatically updated once the network is restored, ensuring users always see complete and accurate performance records.
São Paulo, Brazil, August 26, 2025 -- Sungrow, the global leading PV inverter and energy storage system provider, launched its next-generation microinverter S2500S-L to the Brazilian market at Intersolar South America 2025, held from August 26-28 in São Paulo. Designed for superior reliability, efficiency, and ease of use, the S2500S-L is poised to accelerate Brazil’s clean energy transition.
The Best Fast-Track Option in the Brazilian Market
The S2500S-L delivers a power output of 2.5 kW per unit. By connecting three units, it is possible to reach 7.5 kW - a limit that falls within the fast track procedure (Brazil’s Normative Resolution No. 1,000/2021), ensuring simplified technical approval by power distributors. Featuring an innovative topology design, it achieves a power density of 455 W/kg, ensuring lightweight and high efficiency. It supports four independent MPPT inputs with DC input currents up to 18 A, ensuring seamless compatibility with a wide range of solar modules.
Engineered for Extreme Heat
Many regions in Brazil, particularly in the North, Northeast, and Central-West, experience high year-round temperatures. Microinverters are often installed in tight spaces between solar panels and rooftops, where summer heat can cause conventional devices to reduce output or shut down. The S2500S-L is built to perform well in these conditions, operating at 45°C without power derating and maintaining reliable output up to 80°C.
The design improves heat dissipation efficiency by 10–15% compared to conventional solutions, ensuring consistent output in extreme climates.
Faster, Simpler Installation
For installers, convenience is a priority. The S2500S-L’s one-click configuration feature allows settings applied to one device to be automatically synced across all devices on the same network, reducing setup time by over 66%.
Additionally, leveraging Sungrow’s iSolarCloud intelligent energy management platform, users can view real-time power generation and health status for each microinverter. The platform also supports remote diagnostics and fault resolution, minimizing downtime and maintenance costs.
Strong Communication for Every Watt
The S2500S-L delivers strong communication competitiveness, delivering signal quality 5–10 dB above industry averages. Transmission power is increased by 10%, enabling a stronger and longer signal reach. With a high receiver sensitivity of -93 dBm, even weak signals are easily detected, maintaining stable communication even through two walls.
When short-term disconnections occur, the system automatically reconnects within seconds, ensuring smooth and uninterrupted data transmission. If longer outages happen, the S2500S-L provides 24-hour data retransmission: generation data is securely stored and automatically updated once the network is restored, ensuring users always see complete and accurate performance records.
Comprehensive Reliability
Reliability is built into every stage—from component selection to manufacturing and testing. For customers, this means lasting peace of mind, enjoying reliable, clean energy every day, for years to come.
During component selection, components undergo rigorous reliability verification, cumulatively exceeding 500,000 hours, including core component tests that exceed 10,000 hours to ensure long-term durability.
The S2500S-L is tested to withstand temperature extremes from -40°C to 125°C and rapid thermal cycling, demonstrating proven durability. Externally, it features IP67 protection and C5 corrosion resistance. Even after more than 1,000 hours of high-temperature, high-humidity, and heavy salt spray testing, the S2500S-L continues to operate flawlessly. These features ensure unparalleled reliability in Brazil, where regions such as the Amazon and coastal areas experience high humidity, and the Southeast faces significant rainfall.
In addition, the S2500S-L features industry-leading electromagnetic compatibility performance, achieving the world’s leading Class B rating — the home-appliance level standard.
The new Sungrow microinverter simply delivers everything the market values: maximum array utilization, high derating temperature, enhanced Wi-Fi communication, an extremely simplified commissioning process, and competitive reliability and safety. With the S2500S-L, Brazilian households can move beyond simply generating clean power, producing it more efficiently, more reliably, and with greater ease, helping to shape a smarter, higher-quality zero-carbon lifestyle.
