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.

On a day when the electricity provider had a maintenance day the inverter could not even power itself therefore we had no electricity that day!

The delta inverter died in December. Delta sent out a replacement but when wired, it proved faulty too. Delta sent out inverter 3. Yep, faulty as well. Inverter 4 arrives in March- finally one that works. Meanwhile we score a large power bill. We ask Delta for assistance- didn’t want to know us. 3 faulty products and no consideration for the expense incurred due to their sub standard product . Not happy. Solar installers were great- product shoddy.

My Delta Inverter , Solivia 5.0. Was Installed on or about 3rd Dec 1912, supllied by Origin, in Victoria, since it was installed , the inverter used to drop out on its own accord 4 to times a year,then i restart the unit by the following the closure and start up of the inverter, this was reported to Origin, nothing was done.Now it drops out constantly, I have taken pictures and videos of it. When it drops out on the screen it reads.' SYCHRONIZE TO AC'.. It takes on or about 1 minute and sometimes just less for restarting. I have taken pictures of it and also videos, videos just tells the whole story, I have reported back to Origin, the INVERTER, is under warranty, a technician has been arranged to come out and inspect it. Would it be possible if some info was emailed to me, whats causing this problem.

Inverter seems extremely reliable - no moving parts, screens, obvious points for failure.
Setting up the app to monitor production isn't super straightforward, but we figured it out. Once set up, it does exactly what you need it to do and nothing more.
Has a 10 year warranty through installer, rather than the usual 5.

I was excited to have an app to view the production however the app is not user friendly and cumbersome so it is not worth the bother of logging on, changing to the different wifi and waiting for app to start up. The idea is good but needs some consumer input to improve the ease of use

5kW Delta Inverter. The Delta software shows the inverter producing a maximum of 5kW. However we have two separate Engage monitors independently monitoring our solar output and electrical consumption. These show the inverter producing a maximum of 4kW. For example; today the Delta shows we were producing 5kW between 11:55 and 14:50 whereas the Engage monitor shows 4.41kW at 11:55 and 1.74kW at 14:50. The Engage graph is sawtooth whilst the Delta is almost flat line.

Cuts out many times per day (usually several times per hour) due to high voltage. Battery rarely charges, on standby. When the inverter is working, it usually feeds into the grid not battery. Occasionally battery charges, may go to full charge but this is rare. Installers blame SA Power networks but when I contacted them they did several readings at night and during day which were ok.
Installers had me sending photos of my inverter to them but I did not get a response from them. After several months they said it was fault of power network and I should phone them. Installers have checked the installation and say it is ok. They have sent data to the delta people.
Currently a stand off. I do not have a reliable properly functioning system.
I have been promised internet connection by salesman and current person I am dealing with but this seems to have lapsed. I would not need to send photos and the problems could be more easily checked.
I would like a system that functions in my situation.
