Huawei inverter - 5kW - SUN2000-5KTL-L1

Solar installations often lose yield due to shading, mismatched panels, or thermal losses. The Huawei SUN2000-5KTL-L1 tackles these challenges with dual MPPTs, 98.4% efficiency, and a transformerless design that keeps conversion losses minimal. This 5 kW single-phase inverter integrates a DC disconnector and Type II surge protection on both DC and AC sides, reducing external component count and installation complexity. Its IP65 enclosure withstands harsh weather, while natural convection cooling ensures silent, maintenance-free operation. The unit supports battery integration with the Huawei LUNA2000 for energy storage, and smart dongles add WLAN, Ethernet, or 4G connectivity for remote monitoring and control.

Who is it for

Homeowners and small commercial users with single-phase grid connections who need a reliable, high-performance inverter for rooftop or ground-mounted PV systems up to 7.5 kWp. It suits installers seeking a compact, feature-rich solution with integrated protection and flexible communication options.

Tips

Pair the inverter with a Huawei Smart Dongle-WLAN-FE or Smart Dongle-4G for wireless monitoring via the FusionSolar app. Ensure the PV array voltage stays within the 90–560 V operating range, especially in cold weather when open-circuit voltage rises. Mount the unit vertically on a solid wall with at least 300 mm clearance around it for optimal heat dissipation.
