Verano Chooses Sungrow for Chile Solar-Storage Project

• Sungrow powers Verano Energy’s 135MW Chilean Observatorio solar-plus-storage project with PowerTitan 2 batteries, shifting power to peak demand under a 25-year service contract.

Verano Energy has selected Sungrow to supply equipment for its Observatorio hybrid solar and battery energy storage project in Chile. The facility will be built in Marchigüe in the O’Higgins Region. The solar plant will have 135 MW of installed capacity, with Sungrow providing its SG350HX-20 photovoltaic inverters.

The battery storage system will be rated at 152 MW with 606 MWh of capacity, designed to operate for about four hours at full output. Sungrow will provide its PowerTitan 2 battery solution under a contract that also includes 25 years of long-term service. The co-located storage will let Observatorio shift solar generation to later periods and deliver flexible power during higher-demand hours.

How will Sungrow’s inverters and PowerTitan 2 batteries improve Verano’s Chile hybrid project?

• Higher solar energy yield: Sungrow’s SG350HX-20 central PV inverters are built for high conversion efficiency and strong output stability, helping Verano maximize deliverable energy from the 135 MW plant in Chile’s varying irradiance conditions.
  
• Grid-forming and grid-support capabilities: The inverter system can provide dynamic grid services—such as voltage/frequency response and reactive power control—supporting stable operation of the hybrid plant when load and grid conditions change.
  
• Better resilience through modern monitoring: Sungrow’s inverter platform supports real-time performance visibility (site-level and remote monitoring), improving fault detection, reducing downtime, and speeding up optimization during commissioning and later operations.
  
• Battery dispatch with rapid responsiveness: PowerTitan 2 is designed to deliver power quickly when needed, enabling Observatorio to smooth solar intermittency and provide flexible output during Chilean peak-demand windows.
  
• Optimized energy shifting: With the project’s four-hour full-power design basis, the battery can store surplus daytime generation and release it later, improving how Verano matches solar production with demand and grid requirements.
• Advanced power conversion and control: The PowerTitan 2 architecture integrates inverter/PCS functions with battery management to maintain stable charge/discharge behavior, supporting predictable performance for hybrid scheduling.
  
• Battery protection and management: PowerTitan 2 includes intelligent battery management (cell monitoring, thermal oversight, and safeguards) that helps protect longevity and maintain consistent performance under cycling.
  
• Thermal and performance management suited for Chile: The system’s engineered operating controls help maintain output under real-world temperature and operating-profile demands, supporting reliability across long-term use.
• Lifecycle-focused operations via long-term service: The 25-year service scope reduces performance risk over time by establishing long-term maintenance support, planned interventions, and ongoing optimization to sustain system availability.
• Scalable, project-ready integration: Sungrow’s co-located hybrid approach simplifies how solar and storage coordinate, supporting an integrated plant controller strategy for dispatch, grid compliance, and operational efficiency.
• Stronger commercial bankability: Providing both inverter and battery technology under a coordinated supplier/service framework can reduce integration uncertainty and improve long-term confidence in system performance.
