SG3K/4K/5K/6K-D

Product catalog summary

Overview: The document provides technical specifications and features of the SG3K-D, SG4K-D, SG5K-D, and SG6K-D residential single-phase inverters by Sungrow Power Supply Co., Ltd. These inverters are designed for high efficiency, smart management, safety, durability, and user-friendliness.

High Yield: The inverters offer a maximum efficiency of 98.4% and a European efficiency of 98.0%. They support flexible PV string configurations with a DC/AC ratio of up to 1.3, ensuring higher energy yield.

Smart Management: Features include easy local and online monitoring via an app or web, and export power control with a smart energy meter.

Safe and Durable: The inverters are equipped with built-in surge arresters, residual current protection, and high anti-corrosion properties due to aluminum alloy die casting.

Easy and User-Friendly: The compact design (11.5 kg) allows for plug-and-play installation and fast commissioning via an LCD interface.

Technical Specifications:

Input (DC): Max PV input voltage is 600 V, with a nominal input voltage of 360 V. The MPP voltage range is 90 V – 560 V, with two MPPTs and a maximum of 20 A PV input current.
Output (AC): Nominal AC voltage is 220/240 Vac, with a frequency range of 45 Hz – 65 Hz. Total harmonic distortion is less than 3%.
Efficiency: Maximum efficiency is 98.4%, with a European efficiency of 98.0%.
Protection: Includes PV reverse connection protection, AC short circuit protection, leakage current protection, and overvoltage protection.
General Data: The inverters are transformerless, with an IP65 ingress protection rating, and support natural cooling. They operate in ambient temperatures from -25 °C to 60 °C.

Compliance and Grid Support: The inverters comply with standards such as IEC62109-1, IEC62109-2, and others. They support active and reactive power control and power ramp rate control.
