Huawei Smart PV Controller SUN2000-12 KTL-M5

The Huawei Smart PV Controller SUN2000-12 KTL-M5 is a high-efficiency three-phase string inverter delivering 12 kW rated output power (13.2 kVA max apparent) with 98.4% maximum efficiency and 97.9% European weighted efficiency, ideal for commercial PV systems supporting 220/380 Vac, 230/400 Vac, or 239.6/415 Vac grids. Featuring dual MPP trackers with 4 inputs, up to 30 A per MPPT (two strings) and 18 kW recommended max PV power (up to 40 kW with optimizers), a 200–1000 V operating range (370–800 V full-load MPPT), and compatibility with SUN2000 DC MBUS optimizers for 30% higher yields, it optimizes complex arrays with smart air cooling in an IP66 enclosure operating from -25°C to +60°C up to 4,000 m altitude. Advanced safety includes AI-powered arc fault protection, Type II DC/Class II AC surge protection, string fault detection, DC reverse-polarity protection, anti-islanding, residual current monitoring, integrated PID recovery, and input-side disconnection compliant with EN/IEC 62109, G99, VDE-AR-N 4105, and global standards. Flexible connectivity via RS485, integrated WLAN/FusionSolar app, optional Smart Dongle for Ethernet/4G/3G/2G, and LED indicators enables seamless remote monitoring and management. Compact at 546 × 460 × 228 mm and 21 kg with mounting plate, the SUN2000-12 KTL-M5 is backed by Huawei's standard manufacturer warranty for reliable long-term performance.
