SG20KTL

Product catalog summary

Overview: The SG20KTL is a PV grid-connected inverter designed for efficient and reliable solar energy conversion. It features adjustable active power (0-100%) and reactive power control with a power factor range from 0.8 overexcited to 0.8 underexcited. The inverter achieves a maximum efficiency of 98.0% and is equipped with film capacitors to enhance system reliability.

Specifications: The inverter supports a wide DC input voltage range up to 1000V and includes dual MPPTs for flexibility. It is lightweight and easy to handle, reducing installation and maintenance costs. The device is grid-friendly and certified by TÜV, CE, and other standards, ensuring compliance with various international grid requirements.

Input and Output Data: The maximum PV input power is 21000W, with a nominal input voltage of 620V and an MPP voltage range of 280-950V. The nominal AC output power is 20000W, with a maximum output power of 22200W. The inverter supports a nominal grid frequency of 50/60Hz and an AC voltage range of 310-480Vac.

Mechanical and Protection Features: The inverter measures 648x686x246mm and weighs 55kg. It includes various protection features such as anti-islanding, LVRT, DC reverse connection, AC short circuit, and leakage current protection. The device is rated IP65 for ingress protection and operates within a temperature range of -25 to 60°C.

Efficiency and Performance: The efficiency curve indicates performance across different DC voltages (480V, 620V, 800V), with efficiency peaking at 98%. The inverter is transformerless and employs smart forced air cooling for optimal performance up to an altitude of 4000m.

Communication and Certification: The SG20KTL features an RS485 communication interface and a graphic LCD display. It is certified under multiple standards, including EN 62109-1, EN 62109-2, and VDE-AR-N-4105, ensuring compliance with safety and performance regulations.
