The average user has access to just one inverter - The one on their wall, and they all seem to do a job.
We know from other threads that total systems can deliver different outputs, despite their having been bought as a specific output.
Some have complained that their 2Kw design system, never attains that output, and only ever produces eg. 1.6Kw peak output.. ie. 20% Loss
Others declare that their system exceeds the design output, producing 2.2Kw. ie. 10% gain.
Yet others have complained - "I was to get ModelA, but was supplied ModelB, but I was told they are exactly the same?"
Many factors will determine which category a new system will fall under.
The number and variety of Grid Connect Inverters on the market, means that selection of an inverter is complex and confusing, and so when buying a complete installation, it is natural to just accept what is offered by the Installer..
These INVERTERS are all claimed to be the Latest design and the highest quality.
Elsewhere, the comment was made that Transformer-Less GCI's tended to be more efficient ( no transformer loss ) but were possibly not as robust as the transformered variety, which were noticeably noisier because of transformer hum.
So - the $64,000 question is - " What is the BEST inverter to be the proud owner of ? "
( here we are looking at typical 1Kw and 2Kw (output) systems )
Are there any installers out there who have tried various brands and models, and developed a strong preference for certain devices.
In answering, you might assist by declaring the motive for recommendation.. eg. Reliability, Value (cost vs performance), Performance (ie. lowest LOSS)..

I don't recommend them because they are painful to wire and they aren't terribly efficient/pretty/feature packed, but I will say that I have never seen a fault on one that wasn't cause by an electrician. Scratch that - I have seen one fault - a broken cooling fan. Easily fixed though. Bargain priced usually.
I suspect that when the word robust is used, it sort of means solid, chunky and boring.

2 by 15A inputs. They are certainly getting up there in price
The Auroras are cheaper by a fair way though. Both outdoor, both Dual MPPT again.
