Huawei SUN2000-30K-MC0 Inverter 30kW on-grid 3-phase 4 MPPT WiFi

The Huawei SUN2000-30K-MC0 is a 30 kW on-grid, three-phase solar inverter with four MPPTs designed for commercial PV installations. It delivers robust outdoor reliability and integrated WLAN connectivity for straightforward remote management.

Advantages at a glance
All-weather durability: operates from –25 °C up to 70 °C at 95 % humidity with C5M corrosion resistance
Level-4 arc protection: certified arc fault protection with a 500 J arc-generated energy limit
Rapid shutdown: detection across 450 m with a 0.5-second shutdown time
Integrated surge protection: AC and DC lightning protection built in
Flexible connectivity: WLAN, Ethernet, and 4G communication modes supported
Four MPPTs: independent maximum-power-point tracking for complex roof layouts

Performance & Architecture
The inverter provides a rated AC output power of 30 kW across a three-phase on-grid connection. Four MPPT channels allow separate string management, so arrays with differing orientations or shading profiles can each operate at their own maximum power point. This architecture suits commercial parks and business premises where roof geometry varies across building sections.

Safety & Protection
Level-4 arc protection certification is integrated, with support for a maximum arc current of Imax and an arc-generated energy limit of 500 J. Full risk monitoring operates at 33 A, continuously checking the DC side for fault conditions. Rapid shutdown completes within 0.5 seconds, with a detection range of 450 m and a maximum detection current of 33 A.
AC and DC surge protection is provided through integrated lightning protection, guarding both input and output sides against transient overvoltage events. These protective features combine to support safer operation in commercial environments where long cable runs and exposed installations are common.

Environmental Resilience
The unit is designed for outdoor deployment, with freezing tolerance extending to –25 °C, while high-temperature operation is specified at 70 °C with 95 % humidity and 5 % salt spray exposure. A corrosion rating of C5M and dust density resistance of 30 mg/m² further extend the operating envelope into harsh industrial and coastal environments.

Connectivity & Management
Three communication modes — WLAN, Ethernet, and 4G — give installers and operators flexibility in how the inverter connects to a monitoring platform. WLAN is integrated directly, enabling wireless setup without additional dongles in locations where cabling is impractical. The combination of wired and wireless options supports both fixed plant networks and remote sites where cellular backhaul is the only viable link.
