Sungrow, a globally leading provider of PV inverters and energy storage systems, unveiled its advanced microinverter—the S2500S-L—at Intersolar South America 2025, held from August 26–28 in São Paulo. Engineered for exceptional reliability, efficiency, and user-friendliness, the S2500S-L is set to drive Brazil’s clean energy transition forward.
With an output of 2.5 kW per unit, the S2500S-L allows three units to be combined, reaching 7.5 kW. This aligns with Brazil’s fast-track approval process under Normative Resolution No. 1,000/2021, streamlining grid interconnection approvals. Its innovative topology delivers a power density of 455 W/kg, resulting in a compact and lightweight design. Supporting four independent MPPT inputs and DC current of up to 18A, it offers broad compatibility with various solar modules.
Brazil’s North, Northeast, and Central-West regions often face extreme heat. Since microinverters are typically installed in confined spaces between panels and roofs, high temperatures can cause conventional models to derate or fail. The S2500S-L, however, operates at full power up to 45°C and continues to deliver reliable performance even at temperatures as high as 80°C. Its thermal management system improves heat dissipation by 10–15% over conventional solutions.
The S2500S-L simplifies installation with its one-click configuration feature. Using the iSolarCloud app, settings from one microinverter can be synchronized across all devices on the same network, cutting commissioning time by over 66%. Through iSolarCloud, users gain real-time visibility into power generation and system health, and benefit from remote diagnostics that reduce maintenance needs and downtime.
Superior signal transmission is another highlight—the S2500S-L achieves a signal quality 5–10 dB above the industry average. Its transmission power is 10% higher, enabling stronger and wider coverage. With a high receiver sensitivity of -93 dBm, it can detect weak signals and maintain stable connectivity through obstacles such as walls. In case of brief disconnections, it reconnects within seconds. Should extended outages occur, the system stores 24 hours of generation data and automatically updates once restored, ensuring accurate and complete performance records.
Every S2500S-L is built for endurance, with components subjected to over 500,000 hours of reliability testing—including more than 10,000 hours on core parts. It performs flawlessly across a temperature range of -40°C to 125°C and withstands rapid thermal cycling. The unit is rated IP67 for dust and water resistance and offers C5-level corrosion resistance. It has been tested under high temperature, humidity, and salt spray conditions for over 1,000 hours without failure—making it well-suited for Brazil’s diverse climates, from the humid Amazon to rainy coastal regions. Furthermore, it meets worldwide EMI Class B standards, the highest level for residential appliances.
The S2500S-L embodies everything the market demands: superior energy harvest, high derating temperature, robust communication, effortless setup, and outstanding reliability and safety. With this microinverter, Brazilian homeowners can not only generate clean energy—but do so more efficiently, reliably, and intelligently, paving the way toward a higher-quality, zero-carbon lifestyle.
