How do we Determine the Best Solar Inverters: Highlighting Our Approach

1. Products with Most Efficiency

Efficiency is a pivotal aspect of an inverter, as it's responsible for converting the direct current (DC) generated by solar panels into alternating current (AC), which powers household appliances. 

All inverters undergo independent testing to determine their maximum efficiency. They also undergo European efficiency rating. In this evaluation, we've utilized the maximum efficiency to ensure an equitable comparison.

Please note that the Inverters' efficiency varies based on power generation and solar energy input. The maximum efficiency represents the peak performance point on the curve.

2. Product’s Warranty:

Every product comes with a unique warranty and this is a good metric to check the validity of a product. When it comes to inverters, we recommend you go for a minimum 5 years of warranty. However, if you find a good value product with 10 years of warranty, it is much better. 

Many manufacturers offer extended warranties for an additional fee, spanning up to 20 years. Given instances of solar installers going out of business, a brand with an Australian presence and contact number is recommended. To know more about your options, you post a job on Solarmarkit.

Key Features: Which products win?

We've considered unique attributes of each inverter. This has helped us rank solar inverters. After thorough research, Solarmarkit has decided to rank these products at the top. 

1. Enphase’s Micro Inverters: These are handy and are cost-friendly. 

2. SolarEdge: These include power optimizers that can boost up efficiency.

Are there any Limitations of Our Ranking? 

5kW Inverter Option

Indicative Cost Range


$2,450 to $2,550


$1,850 to $2,050


$1,750 to $2,050


$1,250 TO $1,350


$805 to $1,005


$805 to $1,050


$805 to $1,050


$1,750 to $2050

1. Cost is not factored in

It is worth mentioning here that this ranking is not influenced by cost. This is because naturally, more expensive products would have ranked higher than the cheaper costs thus hampering the objectivity of our ranking. 

2. Selective Evaluation

To maintain simplicity, we've focused on key inverter aspects. A more comprehensive approach could yield different outcomes, accounting for factors like 3-phase power or roof shading. Depending upon your residential and commercial needs, you can opt for a better inverter at

3. Manufacturing Country

China is leading the Solar market industry and is the country of origin for most solar products. For the sake of this article, we have also included products from China. If you prioritize non-Chinese manufacturing. Refer to the inverter's datasheet to identify its origin.
