SMA brought "string" inverters to the USA, and now have a full line of inverters for almost any grid-tie application. They feature German engineering and excellent pricing. Harness the energy of the sun - with a solar inverter from SMA. Inverters convert the direct current electricity generated by solar panels info grid-compatible alternating current. They are the heart of every solar power system. As the global leader in solar inverters, SMA is continually on the cutting-edge: industry-leading efficiencies of 98% and superior German engineering ensure reliable and carefree operation. The Sunny Boy solar inverters characterize the Technology- and Quality-Leadership of SMA. They are optimally suitable for use in small and mid-range systems. They impress with first class efficiency, user-friendliness and reliability. The Sunny Boys have been repeatedly acclaimed - and are constantly developing. The new Generation come with innovative technologies such as OptiTrac and H5-Topology. These make the device even more efficient - and therefore ensure a very good solar yield.
