More details

Project value points:
2 MPPT design improves yield where module strings face different orientations or shading conditions.
Wide input-voltage operation supports flexible string sizing and stable production through seasonal temperature changes.
Zero-export, VSG and optional string monitoring features help meet utility requirements and reduce O&M time.
IP65 protection and integrated surge protection make it suitable for demanding outdoor environments.

The 30kW capacity is well suited to distributed PV projects that need strong efficiency, clean grid compliance and straightforward serviceability.
