PV grid connected

Together with our range of accessories, StecaGrid inverters represent an innovative family of inverter solutions for grid-connected solar power systems. Whether being used in a small solar power system for a single family home, or an elaborate combined solution for an industrial complex, Steca grid-feeding inverters all have one thing in common: They offer the highest performance along with maximum flexibility and ease of use.

PV off grid

Two billion people in rural areas still have no access to an electricity grid. Steca has set itself the target of improving the quality of life of these people. To this end, Steca develops and manufactures top-quality products, which, thanks to their long lifetime, ensure extremely low costs. Today, modern and professional electricity supplies are necessary in every part of the world. For these supplies, the focus is on high industrial demands, flexibility, environmental sustainability and reliability. As an expanding company, Steca Elektronik will continue to bank on Germany and Bavaria as an energy industry center: With a total of 650 employees, the company currently manufactures products for an ecological future on a production area of 29,000 m2.
