Have I got the wrong Inverter?

Never used a lot of the Fronius Inverters- More of an Aesthetic thing They're bloody ugly

Each to their own I guess
I'm happy with mine, guess looks take a back seat though I don't think it's particularly ugly. It's very efficient and came with a 20yr warranty so it kind of does it for me!

The fronius is handy in that you can run a single string of 16panels. I've used them a lot where single string is ok as power ones were impossible to get hold of during the autumn so I only used them where I had to have 2 strings.
SMA HFs are quite nice, and no need for bonding.

Fronius aint so ugly!!

The fronius inverters perform well in pvsol, not a whole lot more output but more than Sma and power one with lots of panels.

As far as I can see this is not a bad choice. If you check the data sheet the max ac output is 16A which is ideal for a G83/1 install. One important thing to note and something that confused me for a long time is that on the data sheet, where is states max dc input 3200W is not actually the max dc this inverter can handle. Its something to do with a nominal value they have to state for the European market. To find the max amount of dc you can wire to this inverter simply multiply the the max input voltage by the the max input current. In this case its 9,350W (obviously you'd never want to do this). You might think I'm mad but I've spoken to Fronius and SMA about this. Anyway, as I say I'm sure this inverter will be fine and as long as the rest of the installation has been carried out correctly, and on a clear day will give you your 16A output. I'm willing to bet the installers didn't have clearance from the DNO to go above 3.68kW of output anyway????

Are you sure you spoke to Fronius about this? There is no way that the 3000TL can output 9,350W. It may well cope with the higher power but it certainly won't process it. I believe the only way to truly damage an inverter is to use a voltage which is too high.

The 3000TL AC output is not 16A.

Thanks for all the replies. You have confirmed what I already thought and I will contact the installer to discuss swopping the 3000TL for something more appropriate. My preference would be the 3600TL as all the cables etc are in the correct positions and should make for a easier/quicker job.

It's 16A.

So you don't rate the Fronius IG TL 3.6? Any particular reason?

16A you are right..Fronius kick in voltage is..????

 

[GaryM]

16A you are right..Fronius kick in voltage is..????

Correct me if I'm wrong but 350V?

 

[Somecamel]

Correct me if I'm wrong but 350V?

Correct

Powerone 3.6 is 120v
SMA 4000tl 175v

Correct me if I'm wrong but 350V?

I believe you are right. It will take a lot to wake up, probably spend most of the winter sleeping compared to SMA or Power one

 

[GaryM]

So in the real world why does the IG TL 3.6 yield more with 16 panels when I put them through PV SOL?

PV SOL is not the real world imo...350 v 120..or even 200v if you dont lower power one kick in voltage.
The power one or sma will wake up earlier and go to bed later. The TL sma are second choice.
We had a case of over voltage with a sma 4000 tl, we took it out, put in a power one 3.6OUTD and no problems with the over voltage.

You're right, I made a pretty silly comment comparing PV SOL to the real world. Doh!

Dont worry mate I had a nighmare last night I was going broke . Woke up and it was all true. LOL
