Description

Product Description

The Huawei SUN2000-50KTL-M3 inverter is engineered to maximise energy harvest and reliability in medium to large commercial solar installations. With a peak conversion efficiency of up to 98.5 percent, four independent MPPT channels, and support for multiple PV string inputs, this inverter optimises PV array performance across varied site conditions. It features built-in arc fault protection, PID recovery to mitigate module degradation, and natural air cooling for long-term operation in harsh environments. The unit supports integration with Huawei’s FusionSolar platform for real-time monitoring, remote diagnostics, data logging, and intelligent system management. Weather-proof IP66 housing and robust grid-compliance make it suitable for rooftop and ground-mount installations with stringent safety and uptime requirements.
