About SolarInvert
SolarInvert GmbH develops and manufactures in Germany grid-compliant inverters for low-voltage applications in the renewable energy sector. The devices operate according to the SELV concept (Safety Extra Low Voltage) with a maximum of 120 Vdc and galvanic isolation via a low-frequency isolation transformer. The portfolio includes solar inverters (SOL), wind inverters for small wind turbines from 300 to 2400 watts (WIN), battery inverters (BAT) as well as heating element controls (Power Unit V2). In addition to its own brand, the company offers product development and contract manufacturing of grid-compliant converters, voltage converters and special devices, whitelabel deliveries also without housing, as well as wind tunnel measurements for small wind turbines. Additionally, repair and overhaul services are offered for its own devices and over 30,000 identical third-party devices. Administration is located in Magstadt, manufacturing and repair in Mössingen (Baden-Württemberg).
