Solar Choice’s Independent Review of Delta Solar Inverters

Delta – a brief overview of the company’s history

Delta Group, based in Taiwan, was founded in 1971 with the primary goal of producing switching power supplies. They’ve expanded into power electronics, industrial building automation, and energy infrastructure projects over the previous 50 years. The Delta Group made an annual profit of AUD$1.1 billion in 2019, indicating that they are financially stable.

Delta began developing their first 260W grid-connect inverter for the German market in 1999. They now produce solar inverters ranging in power from 2.5 to 140 kW and distribute them globally through local websites and offices in the United States, China, India, Japan, Korea, Thailand, and Australia. Noting Hill, Victoria, is the location of their Australian office.

A quick primer on solar inverters

The inverter in a solar system converts the DC electricity generated by solar panels into grid-compatible AC electricity. Inverters are often divided into two types: string inverters and micro-inverters.

String inverters (which include Delta’s whole product line) have long been the industry standard in the solar business. They transport the power generated by solar panels to a central inverter, which converts it from DC to AC electricity that may be used to power dwellings. Delta also specializes in hybrid string inverters, which can both charge a battery and utilize solar energy as soon as it is generated.

Micro-inverters, which are often more costly, offer a miniature inverter for each solar panel installed. This means that each panel runs independently, giving you a better view of your performance and potentially allowing you to take advantage of some advantages in partially shaded settings.

Delta Inverters are a unique type of inverter.

H5A 222 Delta

Single-phase inverters with one or two MMPTs (Maximum Power Point Tracking), three-phase inverters with dual MMPTs, and hybrid storage inverters with two MMPTs and a 6kwh battery are all manufactured by Delta. Transformer less inverters are used in all of the CEC-approved Delta Inverter models, which adds to their excellent efficiency.

The principal series for residential applications, Delta’s home series, is designed to supply electricity with a capacity of 2.5kW to 5kW. This collection also includes the E5 hybrid inverter with a battery backup option.

The Delta H5A 222 inverter (5kW) is one of the company’s most popular residential inverter models. In comparison to Fronius’ similar 5kW inverter, which starts at 80v, the inverter has an incredibly low start up voltage of 35V. The Delta inverter will run longer in the early morning and late evening as a result of this. While the difference will not be considerable in the short term, the savings will add up during the system’s lifetime.

Although it is not suitable for most common applications, this inverter is one of the few possibilities for generating power with only one panel. To generate power, most inverters require three or more panels.

PV Evolution Labs rated certain of Delta’s inverters as Top Performers.

Inverters with the Best Performance in 2019 according to PV Evolution Labs

PV Evolution Labs (PVEL) is well-known for conducting independent evaluations on the performance of solar panels. They also started testing solar inverters in 2019. Because participation in their testing technique is voluntary for solar inverter manufacturers, not all inverter models are evaluated. It is, however, a fantastic proof point for inverters dubbed “super performers.”

Some of Delta’s inverters performed exceptionally well in the following three tests in 2019:

What are the prices of Delta solar inverters?

Delta inverters are manufactured in China and have reached a substantial scale of production, allowing them to offer cost-effective prices of around 23c per watt on the Australian market.

Pricing that is only indicative

  • Indicative Price Range for the Solis Inverter Model
  • 5kW Delta-H5A 222
  • a range of $1,000 to $1,300
  • $2,300 – $2,600 Delta-RPI-M10A 10kW
  • 30kW Delta-RPI-M30A
  • $3,600 – $3,900 – $3,600 – $3,900 – $3,600

Keep in mind that inverter costs often range from 10% to 20% of the total system cost, therefore it is frequently worthwhile to invest in a high-quality inverter because it will have a significant impact on the efficiency and performance of your Solar Power project.

Inverter efficiency criteria for residential use range from 95 to 98 percent. Delta inverters are near the top of this spectrum, with a’maximum efficiency’ of at least 97.5 percent across their whole product line.

A number of Delta models, like the Delta RPI 4.99kW, have a maximum efficiency of over 98 percent (RPI commercial series M6A). With a maximum efficiency of 98.3 percent, this Dual-MPTT string inverter is one of the most efficient alternatives for small commercial applications.

Warranties for Delta Inverters

All CEC-approved Delta inverters in Australia come with a 5-year manufacturer’s guarantee. In Australia, most inverters come with a 5- or 10-year warranty, so Delta is on the shorter end of the spectrum. Clients can purchase an additional five years of warranty directly from Delta, and installers can purchase an extension on behalf of their customers for a total of up to 15 years.

If a customer has a warranty issue, the first line of support for replacing or repairing the product should be the original installer who installed the system. Customers who are unable to reach their original installer should call Delta’s warranty service at 1300 335 823 or fill out a form on their website to receive assistance from their local office in Australia.

In Australia, there is a large selection of Delta Inverters.

The Clean Energy Council has authorized the bulk of Delta’s inverters (under the name Delta Electronics Inc) for the Small-scale Renewable Energy Scheme, Australia’s home solar rebate scheme.

The CEC has authorized the following common residential Delta inverter series and sizes:
