Top 3 Best Solar Inverters in Australia 2022 – Tier 1 Solar Inverter Reviews

by | Sep 27, 2022

What are the top 3 best solar inverters brand in Australia? How to judge the inverter is good or not?
• The answers are the insight into consumer demand, simple and friendly human-machine interface,
• The technical compliance of grid regulators, the convenience of installation and attention to safety with performance.
In one word, quality and performance both together to support the inverter to be the best inverter brand.
1. DC Input Isc and Imp
Let’s compare the maximum short circuit current (Isc) and maximum input power current (Imp) of different brands.
The latest Australia Solar Installation Standard AS5033.2021 has been officially implemented on 19 May 2022, which requires that:
1.25×PV Panel Isc <=PCE(Inverter) DC input Isc
i.e. 1.25 times the PV string short-circuit should not exceed the maximum DC input short-circuit current of the inverter.
Taking into account the most popular model 415-watt solar panels for example. The mainstream PV panels maximum short circuit current (Isc) is around 14A and maximum power current (Imp) is around 13.5 A.
According to AS5033.2021, the ISC of inverters should not be lower than 17.5 A, and the Imp of inverters should not be lower than 13.5 A.

The conclusion: EachEnergy (EET5KW-M1) meets the requirement, and EET5KW-M1, which is 22A, is the best.

The conclusion: EachEnergy(EET5KW-M1) meets the requirement and EET5KW-M1 18 A is the best.
2. Start up and Shut-down voltage
Taken the 5KW single phase on-grid inverter for example.

Conclusion: Regarding the start-up voltage: The EachEnergy inverter is the only inverter to start working before 5 am in the morning in the summer months. With regards to the short-down voltage: EachEnergy inverter is the only inverter working until 9pm in the evening in the summer months.
The EachEnergy inverter is generating 2 hours more than other inverters average generation.
This in turn means EachEnergy inverters generate more power and provide installers an extra hour in time to commission and test the inverter in the evening after installation has been completed.
3. Multi Mppt Number, Multi String Numbers

As for Mppt and string number, the more there is, the more flexible it is to install for different complex rooftops. The leading inverter is the EachEnergy inverter – Single phase 8kw (1+1+1) and 10kw (1+1+2), Three phase 5kw (1+1+1) and 15kw (2+2+2).
4. Testing and commissioning method
Many inverter brands have only one way to test and commission, that is Wi-Fi. However, many houses are located in the country side with poor communication signals. The inverters with LCD and button/s as second way to test and commission are preferred. Fronius and EachEnergy have LCD and button/s, which are preferred and recommend.

5. Wi-Fi connection
Each Energy use WIFI + Bluetooth in a two way to apply Wi-Fi configuration. This increases the Wi-Fi success connection rate to 99%+.

6. Max Efficiency and EU efficiency

Higher efficiency means higher yield, here are the comparisons between different brands

After specification comparison from the above 6 perspectives. The brand EachEnergy takes a leading position in terms of design, performance, and installer friendliness.
