About Delta, Solar Inverters

Delta solar inverters review

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.

Really happy with my Delta inverter and PV installation. Has drastically reduced the cost of delivering electricity to my house. Very stable, fairly basic reporting but, get me the information I need

The associated app is not easy to use without some initial help to setup. Once that’s done it’s great!

Had small issue about a month in, where the wifi wasnt connecting to the inverter so I couldnt see my production in the Delta App, contacted Delta and they promptly got me back up and running on the Delta app after a quick talk through of rebooting.

Although the Inverter itself has always worked perfectly from the beginning, I initially had an intermittent problem with the Wifi monitoring access. The service and support that I received from Advanced Solar Technology with support from Delta Solar was excellent. They immediately came out to my house to investigate it and to report back to Delta Solar.

Delta Solar then found a problem within their software package, which they corrected in very quick time. Advance Solar Technology then came back immediately and loaded the new software.
The Wifi monitoring system has worked perfectly since that time.

The WiFi connectivity is a great feature. The app is not the most user friendly, but it provides the info I need. I believe a new version is on the horizon. The Delta M6A inverter is silent - no fans, which was a plus for me.

We had an issue with the inverter after about 3 months where we could not read the output in the Delta app
The first call was to Advanced Solar technology however we were urged to contact Delta directly?
We called Delta and they promptly gave us the fix over the phone (probably 15 minutes) and the app now reads the inverter as previously.

We are concerned that Advanced Sloar should have known the fix and this would have saved the call to Delta.
Advanced solar stated that to fix the problem they would need to come out and charge a minimum hour rate?
There is no after sales service unless you pay

No problems with the invertor, my problem is trying to understand the delta app, example: 35.840 Watt Hours produced today = how many Kilowatts.
