DELTA Inverters for PV Systems

In 1999, DELTA started their Solar Inverter Program, beginning with the development of a 260W grid-tie inverter in Germany.

Since that time their offering has expanded to a full range of solar solutions for residential, commercial and large scale photovoltaic applications. Their PV inverters ranging from 2.5kVA up to 140kVA deliver reliable, high-performance power conversion that combined with their cloud-based monitoring and integration possibilities with energy storage help the customers to reduce their CO2 footprint significantly.

Since 2017 the internationally active Swiss connector manufacturer Multi-Contact AG has been trading as Stäubli Electrical Connectors AG.
