Sungrow Powers One of the World’s Northernmost Solar Plants with High-Performance Inverters in Arctic Finland

Sungrow, a global leader in PV inverter and energy storage solutions, has supplied 180 SG350HX string inverters for a 70 MWp solar project in Simo, Lapland—one of Finland’s largest and the world’s northernmost large-scale solar plants. Developed by Solarigo Systems Oy and supported by distributor PVO International, the project showcases the viability of utility-scale solar energy in Arctic conditions. This marks Sungrow’s second contribution in Simo, following a 60 MWh battery storage project earlier this year.

The SG350HX inverters were chosen for their outstanding performance in extreme cold, wet, and remote environments. With features like 16 MPPTs, 99% maximum efficiency, and advanced diagnostics, they ensure high energy yield and reduced maintenance. Their robust IP66-rated, corrosion-resistant design with smart air cooling enables stable operation even in freezing temperatures, making them ideal for Arctic deployment under PV module structures.

“Sungrow’s SG350HX inverter was a natural choice for this project,” said Jere Graf, Project Manager at Solarigo. “Its performance in previous installations has been strong, and the updated version offers even more flexibility and reliability. We value Sungrow’s technical support and long-term warranty terms, which are essential for projects in remote and demanding locations.”

“As solar energy expands into new frontiers, we are proud to support our partners with technology that performs reliably—no matter the conditions”, added Henry Särkisilta, Key Account Manager at Sungrow Finland. “The powerful SG350HX and its flexible connection options make it well-suited for projects in challenging environments. This project is a great example of how innovation can drive the energy transition, even in remote parts of Europe.”
