The arka tm solar power conditioning units are a new generation of inverters, changing dc energy from solar modules into clean, stable ac power. These pcus are designed for highest efficiency: integrated advanced microprocessor technology combined with pure sine wave output makes them the perfect choice to use with high-end electronics and electrical equipment. We have combined high quality mosfets with mppt-technology and added solar prioritization as an additional feature to offer a device that is clearly ahead of its competitors.
