Huawei SUN2000-115KTL-M2 115 kW 3-phase string inverter

The Huawei SUN2000-115KTL-M2 is a transformerless three-phase string inverter rated at 115 kW nominal AC active power, designed for large commercial and small utility-scale photovoltaic installations. It features 10 independent MPPT trackers with support for up to 2 inputs per tracker, a maximum efficiency of 98.8% at 480 V, and IP66-rated protection for outdoor deployment.

Key features include string-level DC management with smart arc fault detection, integrated surge arresters for both DC and AC circuits, and comprehensive communication options via RS485, USB, 4G, and WLAN. The inverter supports flexible power factor adjustment (0.8 leading to 0.8 lagging) and integrates DC insulation resistance detection alongside residual current monitoring and anti-islanding protection.

Housed in a compact wall-mounted enclosure (1,035 × 700 × 365 mm, ≤93 kg), the inverter operates across a wide temperature range (-25°C to +60°C) and can be configured for either 400 V or 480 V three-phase output at 50 Hz or 60 Hz grid frequency. Smart air cooling maintains efficiency, with nighttime power consumption below 3.5 W.
