Smart, efficient and built for Australian homes
The Sungrow SG2K-S / SG2K5-S / SG3K-S Premium inverters are designed to deliver exceptional performance, reliability, and value for money. Compact yet powerful, this range combines advanced technology with a simple, user-friendly design perfect for homeowners looking for a dependable solar solution that’s easy to install and monitor.
High Efficiency for Maximum Output
With an impressive maximum efficiency of 98.2% and a European efficiency of 97.7%, the SG Series ensures that more of your solar energy is converted into usable electricity. The result? Higher energy yields and faster payback from your solar investment.
Wide MPPT Range for Optimal Performance
The inverter’s wide MPPT (Maximum Power Point Tracking) voltage range allows it to operate efficiently under changing sunlight and weather conditions. This means your system can extract the maximum energy from your solar panels throughout the day even during cloudy periods or low light.
Flexible Design for Modern Solar Systems
With a DC/AC ratio of up to 1.4, the SG Series gives you the freedom to oversize your solar array. This design flexibility lets you add more panels later without upgrading the inverter, helping to future-proof your system. The SG models are also compatible with bifacial panels, offering even more design versatility.
Smart Monitoring Made Easy
Built-in Wi-Fi connectivity allows you to track your system’s performance in real time via the Sungrow app. From your smartphone or tablet, you can view live generation data, monitor system health, and quickly spot potential issues — giving you complete control over your solar investment.
Lightweight, Reliable, and Easy to Install
Each SG Premium inverter weighs just 8.5 kg and features a transformerless design, making installation quick and straightforward. Compact dimensions (300 × 370 × 125 mm) mean it fits easily into small spaces, while its robust build ensures long-term durability in Australian conditions.
Long-Term Warranty and Local Support
Sungrow backs the SG Series with a 10-year standard warranty, reflecting its confidence in product quality and performance. With a local service office in Sydney, Australian customers also enjoy responsive technical support and peace of mind that help is always close at hand.
