Diehl - Inverter Reviews

About Diehl

Diehl is a German company that once produced solar string inverters that were available in Australia.

Company Details

Diehl Stiftung & Co. KG is a family-owned German company established in 1902 and based in Germany (Nuremberg). The Diehl Group incorporates five divisions: Diehl Metering, Diehl Aerosystems, Diehl Defence, Diehl Metall, and Diehl Controls, plus several joint ventures and dozens of subsidiaries.

Diehl become involved in the photovoltaic industry in 2004, producing solar inverters and other solar-related products under the name Platinum. Platinum became an autonomous brand in 2013, but all inverters were still produced by Diehl Controls in Allgäu. Manufacturing continued at the site after acquisition by Mutares Solar GmbH that year; however, Platinum filed for insolvency in 2014.

Diehl Inverters in Australia

Diehl’s range of solar products consisted of string inverters and single and three-phase inverters, with or without transformers; with power outputs in the 2 kW to 22 kW range. With devices offering ingress protection classes IP 65 and IP 66, these were suitable for outdoor installation. Efficiencies ranged from up to 98% for single-phase products, to 98.6% for three-phase models.

Warranty Information

In February 2011, the Diehl Platinum's standard warranty was boosted from 5 years to 10 years, with a 20 year optional warranty that involved an extra fee. For Australians who just had a standard warranty, this means their inverters are no longer covered. For those who had an extended warranty and need to make a claim, the first step is to contact the company that installed the inverter. Failing that, you may be out of luck.

If your Diehl/Platinum inverter has given up the ghost or is approaching that stage and isn't covered by warranty, instead of what will likely be an expensive repair to an ageing bit of kit, consider buying a new inverter.
