Delta solar inverters reviews

Delta Customer Service: 1300 335 823

Delta Energy Systems is a a subsiduary of multi-billion dollar global company Delta Electronics Group. It makes all sorts of industrial, medical and consumer electronics as well as solar inverters.

The company commenced operation in 1971 and has been producing solar inverters since 1999. For the residential market, Delta's H series (Home Series) is the current line, available in capacities from 2.5kW to 5kW. The company also offers the E5 that can be paired with its Bx6.0 battery.

Back in the day, when I worked as a control engineer in a nuclear power station, we used Delta power supplies for reactor control systems. In my experience, they know how to make reliable electronics!

One of the strengths of Delta inverters is that they can get jolly hot (65 degrees celsius) without derating. So they are a good pick in the hotter parts of Australia.

Delta Inverter Warranty Notes

A 5 year warranty is offered on Delta Home Series solar inverters (and its Hybrid E5).

The company's Australian office is located in Notting Hill, Victoria, so local warranty support should not be a problem. However, the first point of contact for warranty issues should be the business that installed your Delta solar inverter, as they bear the responsibility for warranty work.

In the scenario the installer/company is no longer around or otherwise uncontactable, Delta advise that Australian should contact their warranty department on the number listed above.

Delta will then email the customer a warranty claim form, which needs to be filled in and returned. Delta will then arrange for the repair/replacement of the inverter.
