Company Info

Qcells was founded in 1999 in Bitterfeld-Wolfen, Germany. But these days it is headquartered in Seoul, South Korea. It became Hanwha  Qcells after it was acquired out of bankruptcy in August 2012 by South Korea's Hanwha Group. Even before the Hanwha acquisition, the company had an office in Australia, which it set up in 2010.

Qcells Inverters In Australia

Qcells  launched a home solar and storage package on the Australian market combining solar panels, a hybrid inverter, and lithium-ion battery storage in 2019 called the Q.HOME.

This was followed by the Q.HOME+ battery and then the Q.HOME CORE A4. Australia was chosen for the international debut of Q.HOME CORE in 2022.

Then came the A5 battery system. featuring a Q.VOLT A5S inverter. Manufactured in the Republic of Korea, this inverter offered 5kW output power, weighed 33.9 kg, had an ingress rating of IP65 (so suitable for outdoor use) and an operating temperature range of −20C to 60C.  

The Q.VOLT A5S had backup power capabilities, with a switchover time of less than 0.1 second. Among its other features was "dynamic optimizer mode", which involved an algorithm maximising energy yields by incorporating real-time weather information.

Warranty Details

The inverter for the Q.HOME and Q.HOME+ is covered by a 10-year warranty, and the Q.HOME CORE A4S/A5S are covered by a 15-year product warranty.

While Qcells has ceased supplying goods into Australia, warranties related to their products purchased in Australia or New Zealand are managed by a service centre located in Sydney, which can be contacted using the details provided above. But your first contact for warranty issues should be your installer, as they also have warranty responsibility.
