VALLENAR, Chile, Oct. 13, 2026 /PRNewswire/ —  SINEXCEL (300693.SZ) has shipped all StellaON 1250K power conversion systems for RelyEZ Energy Storage Technology Co., Ltd.’s 100 MW/400 MWh battery energy storage project in Chile. The four-hour system in Atacama will charge during lower-demand periods and discharge at peak times, supporting grid flexibility and project returns.

On-Schedule Delivery Supports Project Execution

Large-scale overseas projects require production, inspection, and shipment schedules to remain closely aligned with on-site construction. SINEXCEL completed the full PCS order on schedule, helping RelyEZ Energy protect the timetable for transport, installation, commissioning, and grid connection.

For a project of this scale, delays in a single batch can narrow the construction window. Coordinated delivery reduces uncertainty and helps local teams plan the next stages.

StellaON 1250K PCS Built for Atacama’s Demanding Conditions

Energy equipment in Atacama must operate in an environment that can include high temperatures, dust, and sand. The StellaON 1250K PCS has a maximum efficiency of 99% and a rated-power efficiency of 98.5%. It supports operation from -40°C to 60°C, maintains full power output at 55°C, and has an IP65 protection rating.

Maintaining rated output in high temperatures can reduce power derating and the need for additional capacity. Higher conversion efficiency also limits energy losses across repeated charge-discharge cycles, supporting stable operation and long-term returns.

Strengthening Local Service Capabilities Across the Americas

Following shipment, the project will move into on-site installation and commissioning. SINEXCEL has a dedicated after-sales team in Latin America and seven service centres across the Americas. Technical requests can receive a response within 30 minutes, backed by round-the-clock support and a seven-day spare-parts guarantee.

SINEXCEL has deployed more than 17GW of energy storage capacity across over 5,000 projects and works with more than 600 partners in 60+ countries and regions.

Following shipment, the Chilean project moves into its on-site delivery phase. SINEXCEL will continue to expand its local operations across Latin America, providing customers with support throughout the project lifecycle.
