About Oelmaier Industrieelektronik GmbH

In the mid-late 2010's Oelmaier Industrieelektronik inverters were among the many choices Australians had for residential solar installations.

Company Info

Oelmaier Industrieelektronik GmbH & Co. KG was a German company founded in 1990 that was active in a number of different industries such as aviation, automatic control engineering, soldering technology, medical research, automotive, printing and of course, solar energy. 

At the end of 2018, the Handtmann Group of Companies acquired Oelmaier Industrieelektronik GmbH & Co. KG. In 2020, the company was renamed to Handtmann e-solutions GmbH & Co. KG. It doesn't appear it has continued with producing solar inverters.

Oelmaier Industrieelektronik Inverters In Australia

Available here in the mid to late 2010's were inverter models from Oelmaier Industrieelektronik's PAC and PAC-S series. These offered a power output range between 2.2 and 7.5 KW, and all were transformerless. 

The PAC-S featured a boost converter, enabling a larger input voltage range. An LCD display provided status as well as PV system yield. The 2kW and 3kW units measured 255 x 565 x 200mm and weighed 21kg, while the 4kW and 5kW devices were 255 x 565 x 235mm and weighed 26kg. 

These inverters were rated to work in temperatures - 20 to + 50° C and had an ingress protection of IP44; meaning they needed to be protected from the elements. However, IP65 protection was also available along with an optional cooling system called coolPAC.

Warranty Details

The PAC-Series of inverters offered an 8-year warranty as standard, with the ability to extend this to 12 or even 20 years. That being the case, there may be some Oelmaier Industrieelektronik inverters still under warranty in Australia. For a warranty claim, you should contact the company that installed the inverter first, and if they are no longer around, try contacting Handtmann e-solutions.

If that doesn't bring results, it's time consider a new inverter (and regardless, it probably is anyway).
