What We Do

Electroinvent AD is a Bulgarian joint stock venture founded in the year 1990. The company’s main scope of activity is “Development and production of electronic and power electronic products”. Electroinvent is certified under ISO 9001:2015. More than 15 years Electroinvent produces electronic modules with different applications mainly for the renewable market (wind, solar and energy storage converters and equipment). The produced AC and Servo Drives are developed by Electroinvent and continuously expand power range and functionality. Electroinvent has more than 20 years of experience in the design, production and commissioning of electrical cabinets both under company and customer documentation.

For the achievement of company goals and for the execution of its current and future projects, Electroinvent has built two buildings with a total internal floor area of 4000 m². For all products, Electroinvent insures: installation, put into exploitation, warranty and after warranty service.

Electroinvent executes projects under provided customer documentation BTP (Build to Print) and has a highly qualified team of engineers who can design high quality products based on customer ideas and requirements BTS (Build to Spec).

For the last 10 years, Electroinvent has executed different projects in close cooperation with the company INDRIVETEC AG – Switzerland in the field of:
