The StellaON 1250K units are engineered for Atacama’s desert environment, which combines high temperatures, dust and sand exposure. The equipment achieves 99 percent maximum efficiency and 98.5 percent efficiency at rated power, while maintaining full output at 55 degrees Celsius and operating across a temperature range from minus 40 degrees to 60 degrees Celsius. The systems carry an IP65 protection rating. SINEXCEL states that sustaining rated output under high temperatures reduces power derating requirements and the need for additional installed capacity, while higher conversion efficiency limits energy losses across repeated charge-discharge cycles.
Following shipment, the project enters installation and commissioning. SINEXCEL maintains a dedicated after-sales team in Latin America and operates seven service centers across the Americas, offering 30-minute technical response times, round-the-clock support and seven-day spare parts guarantees. The company reports deploying over 17 GW of energy storage capacity across more than 5,000 projects, working with over 600 partners in more than 60 countries.
Founded in 2007, SINEXCEL produces energy storage, electric vehicle charging and power quality equipment. The company’s disclosed deployments include 17 GW of installed storage, 200,000 direct-current EV chargers and nearly 20 million amperes of active harmonic filters. SINEXCEL plans to continue expanding local operations in Latin America to provide lifecycle project support for customers in the region.
