Inversor Huawei - 4kW - SUN2000-4KTL-M1

The Huawei SUN2000-4KTL-M1 is a three-phase solar inverter delivering 4 kW of rated AC output power, engineered for residential and small commercial PV installations. Its standout capability is the integration of AI-powered arc fault detection (AFCI), which continuously monitors the DC circuit for dangerous arcs and automatically shuts down the system in milliseconds, ensuring maximum safety for your home and family. With a maximum efficiency of 98.4% and a European efficiency of 97.5%, this transformerless inverter converts more sunlight into usable energy, reducing your electricity bills and carbon footprint.

Advantages

The SUN2000-4KTL-M1 is built for reliability and ease of use. Its natural convection cooling eliminates the need for fans, resulting in whisper-quiet operation below 29 dB and a longer lifespan with no moving parts to wear out. The integrated DC disconnector and IP65-rated enclosure allow for flexible installation both indoors and outdoors, even in dusty or wet environments. With two independent MPPTs, the inverter can handle complex roof layouts with different orientations or shading, maximizing energy harvest from every panel. The built-in WLAN interface enables seamless monitoring via the FusionSolar app, while optional Smart Dongles add Ethernet or 4G connectivity for remote management.
