Key Benefits of the Sunny Tripower CORE1

The Sunny Tripower CORE1 has proven its worth in commercial PV and it continues to impress with new features and functions. Check out the key features below that make the CORE1 the preferred choice for commercial PV professionals.

Check SMA compatibility with your SunSpec certified shutdown devices

Access our compatibility document to ensure interoperability with your SunSpec certified devices and SMA inverters. Please note, the APsmart dual-module shutdown device is currently compatible with the Sunny Boy and will soon be compatible with the Sunny Tripower CORE1. Please refer to the compatibility document for updated information and specific model numbers.

1) Unmatched System Visibility

Intelligent IV curve diagnostic

  • Test the health of the inverter’s strings during critical stages in the plant lifecycle (including commissioning and planned maintenance) and easily produce reports to relevant stakeholders (EPC, system owner, etc.)
  • Expedited diagnostics when compared to third party devices, which can add cost and complexity
  • Identifies deviations or changes in I-V curves that can be an indication of installation errors, faults or damage within the PV array that could adversely affect energy production of the PV system

Advanced String Monitoring

  • Benchmark granular power production data to ensure optimal system performance
  • Ensure all strings are operating as expected with automated production monitoring

2) ShadeFix Optimization

  • The CORE1 features SMA ShadeFix optimization, which provides superior power production with a reduced component count versus alternatives, which provides maximum reliability
  • No other optimized commercial solution generates more power or is as easy to install as systems featuring SMA ShadeFix and SunSpec certified devices
  • A typical 50 kW commercial plant from SMA features approx. 30,000 components while a plant using traditional optimizers would require approx. 60,000 components
  • Reducing the number of components keeps potential sources of error to a minimum, ensuring the maximum lifetime of the PV system
