Sungrow has supplied 180 units of their SG350HX string inverters to a 70 MWp solar power plant in Simo, Lapland. The park will be one of the largest in Finland --marking it also one of the world's northernmost large-scale PV installations. The project, developed by Solarigo Systems Oy and supported by distributor PVO International, demonstrates the viability of large-scale PV even in Arctic conditions.
It is already the second project Sungrow supports in Simo after a 60 MWh Battery Storage Project earlier this year. Located just 100 km below the Arctic Circle, the 95-hectare site will host approximately 120,000 solar panels. The project will be connected to already existing wind turbines, forming a hybrid power plant that supports Finland's carbon neutrality goals.
The SG350HX inverters from Sungrow were selected for their performance in cold, wet, and demanding environments. With IP66 and C5 anti-corrosion protection, smart air-cooling and weather-protected design, the inverters will maintain stable operation despite freezing temperatures, ice, and excess moisture. Installed directly under the PV module structures, they will function even when their enclosures are frozen--ensuring minimal disruption and high reliability.
A Partnership for Clean Energy The project is a collaboration between EPC Solarigo and PVO International, which supplied the solar panels and Sungrow's inverters. Solarigo, Finland's largest developer and operator of utility-scale solar PV parks, brings extensive experience in building PV infrastructure in northern conditions. Advanced Inverter Technology: SG350HX is designed for utility-scale PV systems and one of Sungrow's most powerful and efficient string inverters.
Its high power density and smart diagnostics lower installation and maintenance costs. The inverter features up to 16 maximum power point trackers (MPPTs) with a maximum efficiency of 99%, enabling high energy yields under variable conditions. It includes smart safety features such as a reactive power response time, less than 30 ms, stable operation also in extremely weak grids and is compliant with global grid codes.
This project follows Sungrow's recent deployment of a 60 MWh battery energy storage system in Simo together withFRV AmpTank joint venture, further strengthening the company's presence in the Nordic region. As Finland moves toward a greener energy landscape, the PV and ESS projects in Simo showcase that intelligent energy solutions can create a cleaner and more resilient grid, aligned with Sungrow's mission, Clean power for all.
