Pre-engineered enclosures, solar array cages, and smart combiners built to perform flawlessly down to -35°C.
Sweden is rapidly shifting towards fossil-free energy systems, targeting 100% renewable electricity by 2040. This transition has triggered an unprecedented expansion in utility-scale solar parks and rooftop Commercial & Industrial (C&I) solar systems across regional hubs like Stockholm, Gothenburg, Linköping, and Malmö. However, the Nordic climate poses unique operational threats to sensitive photovoltaic string inverters.
Extreme temperature swings, heavy snow accumulation (up to 3.0 kN/m² loads), persistent sub-zero weather, and corrosive coastal breezes along the Baltic Sea demand enclosures engineered for structural and electrical endurance. Standard industrial enclosures struggle with thermal cycling, leading to condensation, component aging, and system shutdowns.
Zeno Electric's customized string inverter and combiner enclosures address these challenges with high-yield insulation, smart pressure-equalizing breathers, and marine-grade C5-M anti-corrosion protective layers. These technologies ensure Swedish PV installations maintain consistent yields throughout cold winter months and damp transitional seasons.
Download Technical DatasheetDual-compartment architecture and ventilation breathers manage the internal microclimate during rapid diurnal temperature drops in Swedish autumns.
Sloped roofing designs and reinforced mounting points prevent snow buildup and structural fatigue on wall-mounted and pole-mounted systems.
Our premium stainless steel and aluminum designs are built to withstand Baltic salt-fog, preventing accelerated galvanic corrosion.
Built strictly in compliance with EU directives and Swedish electrical installation standards (SS-EN 61439).
We leverage 1.5mm to 2.5mm cold-rolled steel, marine-grade aluminum, or stainless steel (SUS304/SUS316) for our main bodies. This guarantees an impact resistance rating of IK10. Enclosures resist mechanical deformation under high wind speeds and winter impacts.
Continuous polyurethane (PU) gaskets are poured directly using CNC dispensing systems to guarantee a permanent, watertight seal. Protection against high-pressure water jets and fine windblown dust is guaranteed under extreme conditions.
We integrate internal heaters for condensation control during Swedish winter nights, combined with heat dissipation fans. Inverters are kept within their optimal operating temperatures to prevent thermal de-rating.
