The Huawei SUN2000-6KTL-M1 inverter is a modern inverter designed for installation in photovoltaic installations, and its purpose is to maximize the energy efficiency of PV installations mounted both on the roof and on the ground. The inverter is sold complete with a WiFi module. The high-current version is characterized by a higher input current on the DC side. The Huawei SUN2000 series inverter is designed to work on a three-phase grid. It is characterized primarily by a greater ability to protect the photovoltaic installation by tracking damaged DC circuits and detecting the occurrence of an electric arc (AFCI), thanks to AI (artificial intelligence) technology. The maximum efficiency of the Huawei device is as much as 98.6%! An additional advantage is the possibility of cooperation with LUNA2000 energy storage systems in the range of 5 - 30 kWh.
