Huawei SUN2000-50K-MC0 Inverter 50kW on-grid 3-phase 4 MPPT WiFi

The Huawei SUN2000-50K-MC0 is a 50 kW three-phase on-grid solar inverter with four MPPTs and integrated WLAN, designed for commercial PV installations where high energy yield and arc-fault safety are priorities.

Highlights at a Glance
Four MPPTs for flexible string configuration across varied roof orientations
Level-4 arc protection with 0.5 s shutdown for proactive safety
Robust enclosure designed for outdoor deployment
All-weather tolerance from –25 °C freezing to 70 °C at 95 % humidity
WLAN, Ethernet, and 4G communication options for versatile connectivity
AC/DC surge protection with integrated lightning protection

Safety & Arc Protection
The inverter provides Level 4 arc fault protection, supporting a maximum arc current of lmax and an arc-generated energy limit of 500 J. When an arc fault is detected, the unit shuts down within 0.5 seconds. Rapid shutdown detection operates across a range of 450 m, and full risk monitoring activates at 33 A. Both AC and DC circuits include surge protection with integrated lightning protection.

Environmental Resilience
The SUN2000-50K-MC0 is built for outdoor installation, tolerating low-temperature freezing down to –25 °C and operating in high-temperature, high-humidity conditions up to 70 °C at 95 % humidity with 5 % salt spray exposure. A corrosion rating of C5M and dust density resistance of 30 mg/m² further extend its suitability for harsh environments.

Communication & Connectivity
Communication is supported through WLAN, Ethernet, and 4G, giving installers flexibility in how the inverter connects to monitoring infrastructure. Integrated WLAN is available out of the box, while Ethernet and 4G provide wired and cellular alternatives for sites where wireless coverage is unreliable. This multi-mode approach suits commercial parks where network conditions vary across installation points.
