Sunways is participating in the SNEC 18th (2025) International Photovoltaic Power Generation and Smart Energy Conference & Exhibition (SNEC PV+ 2025), taking place from June 11 to 13 in Shanghai. At Booth 4.1H-F370, Sunways is exhibiting its updated range of solar inverter solutions, featuring new technologies designed to improve system performance, adaptability, and ease of maintenance.

This year, special attention is given to two newly launched models: the STT-100-150KTL-SE for commercial applications and the STH-3-8KTL-LS for residential use.

STT-100-150KTL-SE: Commercial Inverter with Built-in Safety and Scalability

The STT-100-150KTL-SE is designed for commercial and industrial PV systems. Key features include:

1. AFCI support for arc fault detection, reducing fire risk and supporting long-term system safety.

2. Anti-reverse flow function to prevent current feedback into the grid, ensuring grid compliance in complex scenarios.

3. Support for parallel operation, enabling flexible system expansion and reducing initial investment for rooftop upgrades.

4. Remote upgrades and 24/7 monitoring via the Sunways Portal platform, improving operational efficiency and accelerating fault response.

5. Compatibility with high-current modules, with up to 20A per string, increasing energy capture and module utilization.

STH-3-8KTL-LS: Low-Voltage Residential Hybrid Inverter for Flexible Energy Storage

The STH-3-8KTL-LS is a hybrid inverter designed for low-voltage residential energy storage systems. It offers reliable power supply for homes, especially in areas with unstable or no grid access. Highlights include:

1. High current design, with up to 25A short-circuit current per string and 20A MPPT and string current, ensuring compatibility with high-output PV modules.

2. Off-grid operation and parallel functionality, making it suitable for microgrid setups and homes without grid connectivity.

3. HEMS (Home Energy Management System) support, enabling coordinated control of PV, battery storage, and EV charging based on real-time battery SOC.

4. Strong off-grid load capability, providing up to 200% of rated output power for 10 seconds to handle temporary overloads.

5. Smart monitoring and remote management, including 24/7 system visibility, firmware upgrades, user access control, and multilingual interface via the Sunways Portal platform.

In addition to the new models, Sunways is presenting a wide range of solutions tailored to various application scenarios, including residential, commercial, and hybrid energy systems. The upgraded portfolio reflects the company’s ongoing efforts to enhance system flexibility, safety, and user experience. With a focus on practical innovation and long-term reliability, Sunways aims to support the evolving needs of solar professionals and end users alike.
