SG3KTL-D/SG5KTL-D

Product catalog summary

Overview: The document provides technical specifications and features of the SG3KTL-D and SG5KTL-D string inverters by Sungrow Power Supply Co., Ltd. These inverters are designed for household use with features like low noise levels, easy installation, and optional Wi-Fi monitoring.

Specifications:

Input Side Data: The maximum PV input power is 4000W with a maximum input voltage of 600V. The startup voltage is 120V, and the nominal input voltage is 350V. The MPP voltage range is 110-560V, with a nominal power range of 150-480V. There are 2 MPPTs with a maximum of 1 PV string per MPPT.
Output Side Data: For the SG3KTL-D, the nominal AC output power is 3000W, while for the SG5KTL-D, it is 5000W (4990W in Australia). The nominal AC voltage is 220Vac or 230Vac, with a frequency range of 45-65Hz depending on the grid standard.
Protection: The inverters include anti-islanding protection, DC reverse connection protection, AC short circuit protection, and leakage current protection. Overvoltage protection is provided by varistors.
System Data: The maximum efficiency is 97.50% for the SG5KTL-D and 97.40% for the SG3KTL-D. The European efficiency is slightly lower. The inverters are transformerless with an IP65 ingress protection rating and consume less than 1W at night.
Mechanical Data: The dimensions are 360x390x133 mm, and the weight is 11kg. They are mounted using a wall bracket.

Certifications: The inverters comply with various international standards including IEC, AS/NZS, VDE, and CE among others.

Additional Features: The inverters support flexible communication methods and have a user-friendly interface with optional LED and LCD displays. They also offer natural cooling and can operate at altitudes up to 4000m, with derating above 2000m.
