Description

Sungrow SG15RT is the three-phase string inverter for residential and commercial photovoltaic systems that need to deliver reliably high yields. With a rated AC power of 15 kW and a maximum efficiency of 98.5 %, it converts your solar power especially efficiently and with minimal losses.

Key Benefits for Your System

High yield: The low start-up voltage and wide MPP range get the maximum out of your modules even in low light.
Flexible system design: Two independent MPP trackers, each with 2 strings, allow you to connect roof areas with different orientations.
Safe and durable: Integrated arc-fault protection (AFCI), Type II surge protection, and the high C5 corrosion class protect your investment.
Easy to use: Compact design at 21 kg, plug-and-play connection, and quick commissioning via the app.

Efficient Use of Your Solar Power

The Sungrow SG15RT inverter is the heart of your photovoltaic system, ensuring that the DC voltage generated by your modules is optimally converted into grid-compliant AC power. Thanks to the two independent MPP trackers, you can ideally accommodate even complex roof layouts with different orientations and increase the self-consumption of your solar power. 24/7 remote monitoring keeps you informed about your system's performance at all times, while over-the-air firmware updates keep the inverter permanently up to date. With the integrated PID recovery function and the intelligent IV curve scan, your photovoltaic system remains efficient for many years. This way, you gain a significant degree of independence and noticeably reduce your electricity costs.
