The Sungrow SG12K RT V115 is a three-phase string inverter with a rated output of 12 kW, specifically designed for medium to large residential solar installations. Thanks to the two MPP trackers with a total of three DC inputs, it is possible to connect different string configurations, giving flexibility in solar panel placement and orientation.
The inverter operates in a wide input voltage range from 160 V to 1 000 V (maximum 1 100 V) and can handle up to about 18 kWp of solar panels. With a maximum efficiency of 98.5% and a European efficiency of around 97.9%, most of the solar energy is converted into usable electricity.
Its compact and lightweight design(about 18 kg) makes installation easy, both indoors and outdoors thanks to its IP65 protection rating. The built-in PID recovery function helps to recover loss due to potential induced degradation of solar panels.
In terms of safety, the SG12K RT V115 is equipped with Type II surge protection on both the DC and AC sides, as well as arc flash detection (AFCI) to reduce fire risks. For communication and monitoring, a WiNet module is standard, allowing the inverter to be connected via Wi-Fi or Ethernet. It also supports RS-485 communication and remote firmware updates.
Additional features such as smart IV curve scanning, 24/7 monitoring and simple “plug and play” connections make operation and maintenance efficient. Class C5 corrosion protection ensures reliable operation even in harsher environments.
With a 10-year manufacturer’s warranty, the Sungrow SG12K RT V115 offers a durable and reliable solution for those who want to make the most of their solar power system.
