Thats answered my question on another thread. I will definately be fitting a Fronius IG30 to 12 240w Sanyo panels and not the sunny boy. Theyre great these forums.

Hi BiggsSolar It didn't appear like that on the Fronius configurator unless I read it wrong. It also says: Please note: Module grounding at the Fronius IG TL not possible!
Its all well and good changing the inverter to solve the problem but do you have any idea what was the actual problem with the SMA? Was it an earthing issue? and what effect does the 30ma RCD have on the situation? (I believe SMA recommend 100ma)

The Fronius design tool, like Sunny Design, is only intended to help you match an inverter to an array. The IG TL 30, though oversized, is much more efficient than the IG30 and will definitely produce a better yield.

Just fired up a 10 panel HIT x 250w Sanyo and a 2500 HF inverter. The whole system has never got over 500w despite being running for 2 weeks. The system has produced 24 KWhours in tha time. Have spoken to SMA and they say its a sanyo problem. Sanyo say its SMA. Fault seems to lie with MPP trackers. Trying to get someone to admit liability.
Could anyone suggest a solution. Onther inverter maybe?? failing this I am taking all the panels off the roof FRiday and replacing with Schott or Hyundai. Got to get this fixed as the scaffold alone cost me £2000.00 and not prepared to leave a system that is prone to problems. Any help greatly received

@johnboy, there is no earth issue on this install and the earth thing is only a major issue on the TL range. And no problem with an RCD on a HF, just the TL's i believe.
The reason i changed it out to a Fronuis is beacaus i couldn't think of anything else to do, the issue seemed to be the inverter but SMA hadn't come up with anything other than swapping it out (which is helpful but still not a solution). Their feeling was that it was a Sanyo problem.
No abnormal test results of any kind, no event codes at all and nobody was able to give us a definitive answer, this problem has cost many hours of my time and much frustration for the customer and us and we are still no closer to a solution.
Thank you to everyone who has made suggestions...

@ Yanman, I personally am not quoting on Sanyo panels and SMA HF series inverters at all after this. i have no confidence in the combination.
We have plenty of other systems out there with different panels that are working fine and we really like the HF series in general but i will not match them with sanyo untill this is resolved.
We like the Fronius IGTL series for Sanyo as Biggs has said...

Does this mean using the Fronius IG TL that the array has to be bonded to earth as mentioned in other threads, cos I still can't get my head round that especially after reading this:
Fronius IG TL
field of application
NOTE The inverter is designed exclusively to be connected and
used with non-grounded solar modules (protection class II). The
solar modules cannot be grounded at either the positive or negative
pole.

You should bond the array to a earth spike, the inverter can be earthed at the MET.
As for the RCD issue i think there will be a large debate very soon.

Any update, on your situation? We have one system displaying this fault and we are preparing to swap the 2000HF for a Fronius like the original poster, however I would like to understand what is causing this, wasted a lot of time on this problem!

Ive just installed 14 x sanyo hde240 with sb3000-hf inverter. Only turned on friday. 10 kwh produced over the 3 days but its been cloudy and overcast here in Leeds. Saturday bright sunny day and got peak of 1.5kw. So does this sound ok or am i experiencing this syndrome? Ps fri 2.3kw, sat 5.7kw, today 2.6kw

Sounds fairly low to me, hard to tell without knowing the exact weather conditions but would be worth looking at Sunny Explorer to check the charts.
Down in the SW with the sun out we spoke to a customer who has 15 235 Sanyo's (on a Fronius) and it was peaking over 3000W. The reason we were there was because we were doing test on his neighbours system that has the fault (10 Sanyo 235W and a 2000HF).

hi, i have web box installed so here is the url for the data: thorn Energy and Power
let me know what you think? i know weather has a big part to play, but i have a mate with aurora inverter and sharp mono's, 10 miles away from me with similar facing roof. he was away for weekend so will be comparing with his system from tomoz

To give you something to very roughly compare with - we have just installed 16 x 250's on a West facing roof with a Power One inverter. Commissioned late on Friday afternoon - 13kwh by Sunday morning first thing.....

morpheus75
Doesnt look too good for me then. Will have to look at another inverter. Will give a few days and compare with my mate.
Thanks for help guys!!

just looking at inverters, have i read this right that the power one pvi3600 can be set to 2 trackers? this would be ideal as i have a chimney shade for a few hours in the mornings
Just installed 9 x Sanyo HIT240 HDE with a SMA sunnyboy 2000HF, getting 6 to 8 units per day for the last week, that sound ok?

12x SANYO HIT 240s on a SB3000HF. Single string, no shading. SSE facing roof at 42 deg tilt.
I have seen 2.5 kW in a single hour on a sunny day last week (remember it is October!). It has been producing over 9 kWh per day on average since install on 29/9/2011 in Sunny South Cambs

Just to confirm i will have to change my inverter aswell. Today 3.5kwh. My mates was 8.1kwh and he has 22xsharp mono connected to powerone inverter sim pitch and azimith direction. Lucky scaffolding is still up so now need to create 2 strings!!
Question to the experienced guys power one pvi3600 or the pvi3600outd? Thanks in advance

Morpheus have you taken any adivce from SMA or sanyo on this issue? Have they been helpful or even contactable? I have not been ablt to get through to the UK team all week last week and they are not phoning back after leaving messages or responding to emails now.
Have had to speak to germany but then there's no continuity and i have to explain the whole saga from the very beginning every time i phone. I get the same things every time, 'have you checked the event codes' etc...
Really starting to get fed up with it all now.

to be honest ive not spoken to sma or sanyo purely because of the responses from the previous posts, ie they themselves didnt know what was happening. there are no error logs being reported by the inverter at all so i have nothing to go on with.
personally i am going for installing a new inverter as i am fortunate in that the scaffolding is still on the house so i am going to change the panel config from 1 string into 2.

I should think that SMA should take more interest in sorting this, as it maybe sanyo thats the problem, but its just easy to swap the inverter so they are loosing out.l

No not any nearere solution. Have now replces Sanyo with Hyundai 250w panels but still got same problem. Short citrcuit test and voltage are correct to DC isolater but drops dramatically when going from this to the Inverter.
Any clues anyone ???

No we have just replaced panels after speaking with SMA. Have now got Hyundai panels on. We still have the same problem. Voltage is correct and amps correct at DC switch. AS soon as it goes in to the inverter we are just getting 1.1amps and about 200w power. Have now checked everything. We even put on a fronius 20g inveretr. Looking for some help here. Off to replace DC switch tommorrow.
@ Morphues: I urge you to speak to SMA if you are having this problem. They don't seem to be taking it seriously enough. The germans are claiming not to even know about it by my last phonecall.
@Robert Carter: this is the first i've heard of the problem with a panel other than Sanyo. it suggests to me that rather than a compatibility issue it may be a faulty component of some kind? Has it been any better with the fronius?

Powerone online tech director knows of the issue and suggested to turn opti-trac on bu i couldnt find hat option on the hf inverter. He said on tl it does the trick. I will speak to ma tomoz but i also have a pvi36outd coming tomoz but wont be installing till weekend.

No we have exactly same problem with fronius inverter.Tested all panels on install and short circuit all the correct readings from the array up to the DC isolater. It goes down hill after that
SMA have no idea or solutions to this problem but I suspect its not an inverter problem now as we have now tried 2 SMA 2500HF and a fronius inverter . All do the same
Not exactly impressed with SMA myself.
Power One tech help were helping you out with an SMA problem?

morpheus75
Sorry it was power-store also known as ccl components. I mentioned it to one of their tech guys whilst i was ordering the inverter. He himself was unaware of the issue but his tech directer was and i got an email a few hours later. Soz for confusion

i know there's big things going on now but i have another update to this thread which is contrary to some of my recent ones.
We had a call from the customer we swapped the SB3000HF out for a Fronius IG TL 3.0 today and the fault has reoccurred. Again a nice sunny day where it should have been going well.
This problem cannot be SMA inverters after this, it must be panel or DC wiring problem.
Not what we wanted to hear today after the EST business...

Hi all im new here Just completed my first install and hows your luck i installed 12x sharp nu 250 j5 pannels and an sma 3000hf invertor and i was ready for my first system switch on to find that i was only getting at max 1.2amps and around 400v spoke to sma and they said they had past it on to the germans to find out what was going on in the mean time they have sent out a replacement invertor which will be here tuesday i recomend to everyone stay clear of the sma 3000 hf

morpheus75
quick update i replaced my sma-3000hf yesterday with a power one 3.6 outd, so lets see what happens. again i am comparing with a mate of mine about 10 miles away

Inverter changed 10 days ago and now getting comparable generation readings compared to my friends. Only problem is no sunny days so cannot test properly. Last week 1 sunny day peaked at 1400w but that was the highlight. Every other day 1-2kw generated daily due to overcast cloudy drizzly conditions

Module grounding is only an issue with Thin-Film modules whereby you must ground either the positive or negative DC cable. It is not possible on any TL inverter as far as I know due to the lack of galvanic isolation. i.e. by the very design of the circuitry
