As the director of an Australian solar retailer, people ask me this question everyday and often there isn’t an easy answer. These are 3 of our top selling string inverters in Australia.
I’m sure you are all eager to find out which one is the best inverter… but I want to help you understand which one will work hard for you and your budget.
How do you decide…? I am going to run your through exactly HOW to find out which inverter is best for YOU.
The first thing to consider is your budget.
For those who have a small budget then its best to look towards the Growatt inverter. It’s affordable, high quality and is backed up by a 10 year product warranty. You can certainly rely on this inverter to give you a great long lasting performance for a low cost.
If you have a little bit of extra cash and want to invest a little bit more into your system then Sungrow is the product you are looking for. Considering the quality of Sungrow’s inverters they are extremely well priced. This is a very high value inverter when you compare performance to price.
Of course, here comes the most expensive of the bunch… Fronius. High quality and high performance so with this one you are getting what you pay for. Is this a European brand premium or is it backed by quality?
If you ask around the solar industry or do a little googling, 90% of people will tell you Fronius is the BEST solar inverter for Australian solar systems.
This is probably true…
HOWEVER, It is also the most expensive inverter. In fact it is 3 times the price of a Growatt solar inverter. So is it 3 times better?
Fronius and Growatt both come with a 10 year warranty.
Both also have similar efficiencies, we will go into more details further down. At Lightning Solar & Electrical we have installed thousands of solar systems with these inverters between Melbourne, Brisbane and Adelaide solar installations.
We have only ever had 1 warranty claim with Growatt and they replaced it in 3 days and paid our labour cost to replace it.
Not bad hey?
But wouldn’t you rather not rely on the product warranty and know the product your buying is from a brand that has been around long enough to prove their long term quality?
Well that’s where Fronius is superior.
Fronius have been around for decades making inverters out of Austria in Europe. They have been at the top of the solar industry for longer than anyone and that speaks for the quality of their product.
Sungrow Premium inverter is a great compromise. They are proven to give a high performance.
Sungrow is the second biggest inverter manufacturer in the world, behind Huawei solar inverters. They make an amazing premium inverter that also comes with a 10 year warranty.
They definitely have earned that reputation over the last few years for being one of top inverters on the market.
Although not quite as notorious as the big boy Fronius they are getting pretty close…
When it comes with a much cheaper price tag and with a 10 year warranty it is definitely worth considering!
The only downside to the Fronius Primo solar inverter is the fan can be a little noisy. So make sure it’s not installed on your bedroom wall!
The only thing that may be in question about the Sungrow inverters are that they are made in China.
While China now makes many great solar products there is still a stigma about this for some. But honestly, we think for the price tag this inverter gives Fronius a run for their money.
5 years ago Growatt inverters had a reputation as not being reliable. In recent years they have fixed all their issues and have since earned their new reputation of the best quality affordable solar inverter on the market.
As I mentioned earlier, you could buy 3 of these for the price of 1 Fronius primo and hey, if it does the same job and you’re on a budget that might be a gamble that is worth taking?
Especially when it has the same warranty period as Fronius.
While these inverters are amazing bang for buck. My only issue is every time I have tried to call Growatt tech support they seem to be “out for lunch..” that said, they do get back to you and help with any issues eventually 🙂
