SUN2000-45KTL-US-HV-D0

The Huawei SUN2000-45KTL-US-HV-D0 is a Huawei string inverter. Its user manual covers installation, electrical connection, commissioning, maintenance and troubleshooting. It is rated for 45,000 W output on a 600 V AC three-wire plus PE connection, with a rated output current of 43.3 A and a maximum output current of 48 A. On the DC side, the full-power MPPT range is 800 to 1200 V, each MPPT accepts up to 22 A, and the maximum operating voltage is listed as 1500 V. Maximum efficiency is 98.70% and CEC efficiency is 98.50%. The power factor can be set from 0.8 leading to 0.8 lagging. Protection features include a DC input switch, anti-islanding, output overcurrent protection, input reverse polarity protection, PV string fault detection, insulation resistance detection, and a UL 1699B Type I AFCI. For communication you choose either RS485 or PLC mode. The enclosure is rated Type 4X, and the unit complies with FCC Part 15B.
