I've been quoted for a system using a Power One Aurora PVI-3.0 inverter, any comments?

I was told as a child if you cannot say anything nice, do not say anything ........Enough said !

ask yourself this ....

Which country is renowned for well built high quality engineering .....Germany or Italy ?
Which country puts more emphasis on looks rather than content ......Germany or Italy ?

Do you want an inverter that looks pretty or one than is well built ?

I have two friends with Laverda motor bikes they look great but the electrics fail quite a lot on both machines. Italian engineering ???

Sorry but its Sunny Boy (SMA) German for me, every time.
Not so profitable for an installer but far better equipment.

However you are going to get installers on here saying buy Sharp , Kyocera, Kioto, Yingli as they are the best panels mainly because they are the cheapest and most profitable. In ten years time most of the above panels along with the Aurora inverters will be in skips .

I prefer SMA inverters as an installer

but power one do offer 10 years warranty on inverters .

where sma is 5 years with options to extend.

Now solar edge is a new product with 12 years warranty on the main inverter and then 25 years on all power boxes .

good system installed two this week , :D

I disagree with the sma lovers I think you can buy a whole lot better inverter before you buy an SMA. power one is a great inverter with 10 year warranty. how about fronius that is a great inverter.

Can you quantify why the Fronius is better than the SMA? I am in the Fronius IG40 v SMA 3800 dilemma and opion seems totaly split. Purely on paper efficiency is better with the SMA - can you give any preffered reason to go Fronius?
