SG2KTL-S/SG3KTL-S

Product catalog summary

Overview: The SG2KTL-S and SG3KTL-S are string inverters designed for household use, offering a noise level of 30dB, which is quieter than a house refrigerator. They feature easy installation and optional Wi-Fi monitoring, making them user-friendly and suitable for grid connection.

Specifications:

Input Side Data: Max PV input power is 3000W, with a max PV input voltage of 600V and a startup voltage of 120V. The nominal input voltage is 350V, with an MPP voltage range of 110~560V and 210~480V for nominal power. There is 1 MPPT and a max PV input current of 10A.
Output Side Data: Nominal AC output power is 2000W for SG2KTL-S and 3000W for SG3KTL-S. The nominal AC voltage is 220Vac, 230Vac (Single phase), with a grid frequency range of 45～55Hz/55～65Hz.
Protection: Includes anti-islanding protection, LVRT, DC reverse connection protection, AC short circuit protection, and leakage current protection.
System Data: Max efficiency is 97.50% for SG3KTL-S and 97.40% for SG2KTL-S. The isolation method is transformerless with an ingress protection rating of IP65.
Mechanical Data: Dimensions are 300*370*125 mm, with a weight of 9kg and a wall bracket mounting method.

Performance: The efficiency curve shows performance at different Vdc levels (280V, 345V, 520V), with max European efficiency at 96.60% for SG2KTL-S and 97.00% for SG3KTL-S.

Certifications: The inverters are certified under multiple standards including IEC, VDE, AS/NZS, and CE among others.
