More details

Why it sells well in C&I projects:
• Strong DC oversizing support (high PV input power vs. AC rating) for better yield in mornings/evenings and winter.
• Wide MPPT operating window helps maintain stable production across temperature swings and long string designs.
• C&I‑grade protection: IP65 enclosure plus Type II DC/AC surge protection improves reliability in harsh outdoor sites.
• Grid‑support features: supports zero‑export applications and VSG (grid‑support) use cases where required by utilities.
• Optional string‑level intelligent monitoring to speed up troubleshooting and reduce O&M cost.

Ideal for: factories, warehouses, logistics parks, shopping centers, and ground‑mount PV plants where three‑phase grid connection and high efficiency are top priorities.
