What does the history say about its recent manufacture?

Any customers will look for an inverter that has had an elegant and historical acceptance. The companies that are on the electric-power production for decades become the first choice for the users, because their long-term existence in this field provides a guarantee to them that they have sufficient knowledge and expertise in manufacturing the inverter-related power devices to raise the bar of the quality. Hence, Delta group is privileged to have been involved in manufacturing some of the finest industrial, medical and various useful electronics, including inverters.

When the Delta company was established back in 1971 in Taiwan when it specialized in supplying the reactor control systems, it could be anticipated that this company, after joining the solar inverter manufacture in 1999, would make a long stride in renewable sector development. Initially, Delta’s contemplation was to make string inverters, hybrid inverters, battery storage systems, and EV chargers. Now, the company is too huge to expand its boundaries to Thailand, China, Europe, and recently Australia.
 

What is Delta’s achievement/Accolades over the years?

In a short possible time, the Delta company has received an awful lot of awards and recognitions, along with the fame. It was feasible due to their business progress, technological advancement, and corporate social liabilities.

2012, Delta was chosen for two prestigious Dow Jones sustainability indexes – the DJSO World Index and the DJSI Asia/Pacific Index in the second consecutive year.
Delta was awarded the first out of 29 leading companies for their high-class electronic equipment sector and hence given a name as “Sector Leader.”

2010 turned out a terrific year for the Delta for their acquiring of 47 internationally recognized design awards, such as iF, Reddot, CES Innovation, Computex Best Choice, and many more.
 

What is so unique about the Delta?

Delta had worked at its fullest level to reach this height through their meticulous and rigorous quality testing. They bear the necessary funding of their R&D facilities by endowing it with 6% to 7% of their annual sales revenue so that they can produce some of the world’s most unique and eco-friendly inverters to avoid causing more harm to the global warming crisis.

Their world-famous R&D facilities are located in China, Europe, Japan, Singapore, Thailand, and the USA. These are the reasons why the Delta’s new inverters are capable of producing a maximum efficiency up to 98.8%.

Delta’s home series, suitable for the residential use, is a perfect example of how brilliantly an inverter can supply power with a capacity from 2.5kW to 5kW. Besides, their E5 inverter comes with a Bx6 battery option. However, the latest Delta series H5A-222 has all the attributes to secure in the ranking of the best residential inverters’ list. In addition to, this noble inverter has a built-in certified DC isolator to prevent any electricity flow during the outage.

Its outstanding low PV start-up voltage of 35V allows the opening of the voltage window to a greater extent resulting in this inverter can start to generate the electricity from the sun from very early morning while the other branded inverters take time to remain inactive. Also, the lowest shutdown voltage of 30V causes the voltage window to close immediately to stop the flowing of the current. Therefore, the longer “Awake” time ensures more savings and return on investment.

Whereas most of the average top-notch inverters utilize at least 3 or more panels to generate the desired amount of electricity, Delta H5A-222, in contrast, can generate power using only one panel, which is awe-inspiring. We will talk more about various ranges of inverter of Delta in the end of this Delta inverter review.

One of the biggest landmarks of Delta’s latest inverters is its ability to withstand hot weather like 65 degree Celsius while supplying the electricity without deteriorating the operation of the inverter. And in this way, it also remains chill, which is remarkable. One of such examples is Delta’s 5kW three-phase inverter; it gives its full range of performance in a temperature like 52 degree Celsius.

Currently, Delta’s primary target is to set and install their various range of inverters in the commercial properties to revolutionize their electricity spectrum that comply with the industry specifications and design quality. Most of their inverters are either single-phase with 2.5/3/4kW or hybrid inverters of 5kW with three-phase 5/10/30kW 6kWh battery.

Although Delta inverters are manufactured in countries like Thailand, China, Taiwan, and Europe, inverters designated to be manufactured for Australia take place in China.
 

Delta Inverter’s Warranty and who to contact for replacement in Australia?

Delta’s main office is located in Normanby Road, Notting Hill, Victoria. Therefore, any issues with the faulty inverter or replacement within the warranty period are no longer a threat or fear. Usually, all the Delta’s inverters, including Home series, as well as their Hybrid E5, come with a standard 5-years warranty, which counts from the date of the installation. Although it doesn’t sound quite a decent warranty period as most of the latest inverters come with a 10-12 years standard warranty, you can easily extend your warranty to 10,15 and 20 years by fulfilling contact section. Amazing, isn’t it?

However, for any replacement or faulty issue with your current Delta inverter, you are always recommended contacting your main installer who firstly installed it. In the case of unavailability or not being found, only then you should contact them in the following contacts;

For any failure or fault of the products, customers should contact the Delta service centre at Delta Energy Systems Pty Ltd.

The phone contact is 1300 335 823. In this service line, you have to talk about the nature of the failure.
You can also email at solarsupport@deltaww.com with a briefing about the failure.
Or you can straight go to the contact section for more information or enter here to send a replacement request.
 

How does this replacement claim work?

It was mentioned earlier in this Delta inverter review that you need to submit the replacement form to get the replacement. In this instance, once you submit it, it takes 6 working days to review your process and get the replacement inverter. Once received, you ought to contact your local installer to install the replaced one and put the faulty one in the box to send it back to the service centre.

After testing and inspecting, if the inverters are deemed faulty, you or your installer will be reimbursed up to AUD 150 + GST. The reimburse process takes about 3-5 weeks from the collection date.
 

How is Delta’s Monitoring System?

You can use SOLVIA Monitor 2.0 to monitor your Delta solar inverter remotely and wirelessly. Besides, Web’log and solar-lo monitoring system will keep eyes on your system to check your inverter’s status, along with self-consumption and many more features.

Delta_s_Monitoring_System

Since you will monitor wirelessly or remotely, you need a cloud-based monitoring app, which is done via mydeltasolar app. This app while being used, had undergone some of the reliability issues, but after taking some steps to amend the errors and improve the interface, this app has increased the compliance, and the customers are benefitting from it as soon as they install it.
