Why choose it

The SUN2000-6KTL-M1 combines high efficiency with a compact, fanless design that operates almost silently. Its IP65 rating allows installation outdoors, and the integrated DC switch adds safety during maintenance. With support for smart dongles, you can monitor performance remotely via the FusionSolar app, ensuring your system runs optimally.

Ideal use cases

• Residential solar systems up to 6 kW with three-phase grid connection
• Small commercial rooftops needing flexible MPPT configuration
• Installations with potential shading or multiple roof orientations
• Systems planning future battery storage expansion

Good to know

This inverter is transformerless, which contributes to its high efficiency and light weight. It requires a compatible smart dongle for wireless communication; the dongle is sold separately. Ensure the AC grid voltage matches your local standard (230/400 V). The unit is battery-ready, meaning you can add a Huawei LUNA2000 battery later for energy storage.
