São Paulo, Brazil, August 26, 2025 — Sungrow, a global leader in PV inverters and energy storage systems, introduced its next-generation microinverter, the S2500S-L, at Intersolar South America 2025. Designed for high reliability, efficiency, and ease of use, the S2500S-L aims to support Brazil’s clean energy transition.

Ideal for Fast-Track Approval

With an output of 2.5 kW per unit, three S2500S-L microinverters can form a 7.5 kW system—fitting Brazil’s fast-track approval process under Normative Resolution No. 1,000/2021. Its innovative design achieves a power density of 455 W/kg, making it both lightweight and efficient. It supports four independent MPPT inputs with DC current up to 18 A, ensuring compatibility with most solar modules.

Built for High Temperatures

The S2500S-L operates at 45°C without derating and maintains reliable performance up to 80°C—essential for Brazil’s hotter regions. Its thermal management improves heat dissipation by 10–15% over conventional solutions, ensuring stable output in extreme conditions.

Quick and Easy Installation

The one-click configuration via the iSolarCloud app allows settings to sync across all devices on a network, cutting setup time by over 66%. Users can monitor real-time performance and troubleshoot remotely, reducing maintenance needs and downtime.

Enhanced Communication

With transmission power increased by 10%, the S2500S-L offers stronger and wider signal coverage. Its high receiver sensitivity (-93 dBm) ensures stable communication, even through obstacles. In case of disconnections, it stores 24 hours of data and retransmits once reconnected, ensuring complete and accurate records.

Proven Reliability

The microinverter undergoes stringent testing, including over 500,000 hours of component reliability tests and 10,000 hours on core parts. It withstands temperatures from -40°C to 125°C, rapid thermal cycling, and holds IP67 and C5 corrosion resistance ratings. It also meets Class EMC standards, ensuring safe operation in diverse Brazilian climates.

The S2500S-L combines high efficiency, thermal resilience, robust communication, and simplified installation—offering Brazilian households a reliable, easy-to-use solution for smarter and more efficient clean energy production.
