Description

Introduction

With the Huawei SUN2000-40KTL-M3, you get a modern, top-tier inverter designed for professional PV systems with high demands. Whether for commercial rooftops, ground-mounted arrays, or large-scale installations: this device delivers power, efficiency, and robustness for demanding projects.

With a maximum efficiency of up to 98.7% and a European efficiency of 98.4%, you achieve excellent energy yield and, as a result, strong economic performance.

The SUN2000-40KTL-M3 features four independent MPPT channels and supports up to eight DC inputs. This allows multiple string arrays to be cleanly separated and operated optimally.

With a maximum input voltage of 1,100 V and an MPPT voltage range of 200 to 1,000 V, the device is well suited for modern high-power modules.

The inverter also excels in practice: compact dimensions (640 × 530 × 270 mm), a weight of around 43 kg, and a fanless design make installation easy and ensure quiet operation.
