The table above shows the current prices for the most popular solar inverters.

The column 'Battery' indicates whether the inverter model is a 'hybrid' capable of plugging in a battery.
This type of battery connection is called 'DC Coupling' because the battery is directly charged by the inverter from the solar panels.

Alternatively, an 'AC coupled' battery, the most popular being the Tesla Powerwall 2, can be connected to any home, with or without solar, as they use their own inverter.
In Western Australia, AC coupled batteries are restricted to a maximum charge/discharge/backup rate of 3kW which is why they are less popular in WA than elsewhere in Australia.

If your 'Main Switch' in your switchboard looks like this, you have three phase supply.





Why such a large range of prices?
If I take 5kW single phase hybrid (battery capable) inverters from the list above, we have...
Growatt XH at $1,320
Huawei L1 at $1,700
Goodwe EH at $2,310
Q.Cells Volt Core $4,620
Sungrow SH5.0RS at $2,530
Fronius Primo GEN24+ at $3,345
SolarEdge Energy Hub at $3,360.

That's quite a spread of prices for what appears to be identical products, but there are very clear reasons for it and it really doesn't have a great deal to do with 'quality'.

The cheapest, Growatt XH is only cheap because it isn't fully functional to connect to Growatt's battery. You need to buy an extra $600 box for that.
The Goodwe, Q.Cells and Sungrow inverters include full back-up inside the inverter where the others all require an external 'back-up box' costing upwards of $1,000 installed.
(Back-up is the feature where, in the event of a grid outage, your home is still getting power from the battery.)
Q.Cells use 'bundle' pricing, so the inverter on it's own is really expensive, but bundle it with their battery and it's $1,200 cheaper.
Q.Cells warranty on both the Q.Volt Core inverter and Q.Save battery is 15 years parts and labour. Substantially better than anyone else.
Fronius (Austria) and Q.Cells (South Korea) inverters are the only ones not made in China.
The most expensive, SolarEdge, is actually about $1,860, but you need to fit optimisers to every panel with SolarEdge inverters and that adds $1,500 to the price.


What do I recommend?
For smaller installations (e.g. 5kW inverter) the Huawei L1 and M1 (single and three phase) inverters tick the most boxes.
Both are plug and play ready for the superb Huawei battery (5kWh to 30kWh of storage in 5kWh modules).
Top quality, near zero failure rate, stylish looking, great reporting, 24x7 support and the price is exceptionally good for a hybrid.

However, if you aren't staying in the home long enough to ever justify a battery then the standard inverters from Growatt, Goodwe, Sungrow and Solis are all perfectly good products.

If you are anti-Chinese, then Q.Cells offer a turnkey solution of panels, inverter and battery, all made in South Korea. Excellent warranty as well.

For 10kW installations, which in WA, is three phase only, I think getting a hybrid inverter makes a lot of sense. This is because if you want a battery later and you buy a regular inverter, your choices will be very limited. For example, you could later 'AC Couple' a Tesla Powerwall 2, but your charge/discharge/backup rate would be limited to 3kW compared to 10kW with a hybrid AND the Powerwall can not keep the solar inverter alive on three phase so when the grid goes down you don't get any 'top-up' from the solar panels.
At the moment, Huawei have not released their 10kW hybrid in Australia and whilst 2 x 5kW Huawei is a reasonably good solution, if backup is important to you then the 10kW hybrids from SolarEdge, Sungrow, Fronius and Goodwe are all good choices, with my preference being Sungrow because they have their own battery and built in backup, no external boxes of contactors etc required.


If you want everything under a single platform then SolarEdge have their own panels, optimisers, inverter and battery and later next year, an EV charger and Home Automation (turning appliances on/off remotely).
Although SolarEdge have all of their equipment manufactured in China, they are an Israeli company, which appeals to some people who don't want to buy a Chinese brand.
I would advise you pay the extra $400 for the SolarEdge Energy Hub inverter over the de-featured Genesis, and note that the prices for SolarEdge in the table above include SolarEdge optimisers on every panel because the inverter can't work without them.

Goodwe have some interesting hybrid inverters with, like Sungrow, back-up fully built-in, but as with Fronius, the lack of their own battery makes them less appealing than Sungrow and Huawei.

SMA are a great brand which used to have a major following in the early days of solar but they don't seem to be the force they were anymore. The three phase inverters are made in Germany. SMA still do not have any hybrid inverters which I find very surprising.

There are other brands. LG for example, who have lost a lot of battery business as inverter manufacturers expand into battery manufacturing, have tried to counter that by releasing their own inverter, but it is in reality the Goodwe ES.
General Electric (GE) have also re-badged a Goodwe and panel manufacturer Canadian Solar have a re-badged Solis.
