Huawei Inverter Single Phase SUN 2000-5KTL-L1 – 1075346

The Huawei SUN2000-5KTL-L1 is a state-of-the-art single-phase solar inverter designed for residential and small commercial solar systems. It blends extremely high efficiency (≈ 98.4 %) with hybrid-ready features, allowing integration with batteries and future expansion. The dual MPPT (maximum power point tracking) design accommodates two independent strings, enabling flexible PV layouts and better performance under shading or mismatch conditions.
With active arc fault protection, smart grid compliance, and built-in communications (WiFi, RS485, optional dongles), this inverter offers both safety and connectivity. It supports plug-and-play battery connection and works seamlessly with Huawei’s LUNA and LG-Chem RESU battery lines. The IP65 rating means it’s built to handle outdoor installations while maintaining durability.
Key Features
