CM

If you are stuck and want your inverters back just let me know, as you know I'm not that far from your "small house".

Genuine offer to help - not tongue in cheek, as it will be a while before I get round to using the inverters in anger.

Best regards

Fred

Hi Paul,

Re your comments....."try disabling the FSPC in #250.28 (ChrgCtlOp) by changing to "DC inputs" only or something like that,

Did you try this CM (from my first post and several others) if so, and all your other settings are right the inverter should NOT move off it's set frequency. I have an email somewhere from SMA telling me this because I asked them last month. If you did set this and the AfraEna then you have a serious software or inverter problem."


And yes Paul I did reply to you saying I had set these settings to "DC Inputs" and yes the Inverter still went to 60Hz.

Each time the Inverter went to 60Hz I shut down and did a Factory reset.

I have sent an email to SMA, and awaiting a reply.
But as I said before the, SMA SI Specialist chap in Germany was to the point about too much DC Coupling and over voltage.

And Yes, I do have all the relevant SMA Manuals.




Then as I said several times it's nothing to do with the frequency shifting or DC coupling. As regards the manuals I've posted you several links re the battery shunt and frequency shifting and you've said 'they aren't in my manual' or 'my page 79 says nothing about that'  so I thought you had the wrong ones.

Sorry, didn't mean to offend, hopefully SMA will get back to you shortly with an easy fix.

Good luck, Paul

Thanks FB for your very kind offer, much appreaciated.

However, I will stick it out for the next month, and see how the SI behaves and also what SMA have to say.

Are you setting it to 220v or 230v??  France is 230v  America is 220v  make sure because the freq will change too

Hi 'rogeriko',

On set up, from reboot Factory settings, I install/set the 230 V / 50 Hz 230.0 V .

And, 230 V / 50 Hz 230.0 V, shows on the Inverter settings, but it has been going to 60Hz even though those settings say 50Hz.


'Biff',  ..... I have removed those earlier posts about what I believe manuals should say, as folk like 'billt' are correct, my concepts are old fashioned and irrelevant in todays electronics consumers market place.

This SMA mess is just seriously depressing,....... but as 'billt' says, SMA are correct,? ......... So I suppose I will just have to get used to and live with modern business society ethics.

Should have heard the warning bells when 'billi' mentioned about the SMA President saying that his products were only good for 10 years.?

Yep, will start looking for a good old 10,000kva APC UPS.

I've read this post with interest and whilst I can't contribute anything helpful, I have to say that the only reason to pay for a 'quality' product like SMA is to get something that works reliably, and if it doesn't do what it's supposed to, then the manufacturer should bend over backward to sort it out.

It's very surprising that it can wander up to 60hz when set to 50 and not be considered faulty. If it IS caused by the dc coupling limit then that is a fairly serious design flaw in an off-grid inverter IMHO and prospective buyers should be made aware of the limitation before they buy. ac coupling is all well and good but makes the off-grid system 100% dependent on the SI.

I too miss the times when I could go down to the library and look up my old 1970's valve-hybrid TV in the 'Radio and Television servicing' manuals' and get all the circuit diagrams complete with testpoint voltages and scope waveforms - made fixing the TV as simple as painting by numbers; and whilst it may be impractical for a lot of modern electronics with multilayer PCB's and microcontrollers, there are parts such as main power boards and power supplies that are still relatively simple to work on and are often the parts that are prone to failure, which could still be diy repaired.

 fingers crossed! that SMA get off their a**e and sort your inverter out - pronto.

Hi Marcus,

Yes, unfourtuenetly it looks like our reasoning on better information on electrical products is for the Dinosaurs, ie Me.

As I have said, 'billt's' reply at first shocked and angered me. Then I realised that similar modern folk have the same response, even my 15 year old.

 Sad to say modern society see everything as throw away, or put up with the fault then throw away.

As my boy said, "Today its all about getting a product made as cheap as possible, then everyone takes their commission on the sale, its not about the product its about the sale and the infrastructure/installation around the sale." I don't argue with him as he will have to live in this Brave New World.

(Hopefully my gentle insights to real stuff are getting through to my boy's).

I have just posted on billi's German Forum. Now I will get my Ear Bent.  wackoold
And still no reply, not even acknowledgement from SMA, so hence the posting.

CM, I agree with most of what's been written, the thing is, you set it at 50hz, and for what ever reason it ran all the up to 60hz, that in my book is way out of spec. That being said you were in expert/installer mode, but for SMA to say its the DC charging side that's the problem sounds a lot of pish to me, it should shut down with a fault code before it even gets any where near that frequency. I think you need a better explanation from them.

He needs to phone them up NOW before something sets on fire. He needs to contact the guy who sold it to him, there is something seriously wrong with this inverter or it's software. It is no good posting on forums about it, the seller sold it and SMA made the fecking thing. They are the people who should be sorting this and you need to tell them that. As I said before their service is first class and just one phone call to someone who clearly 'got it wrong' is hardly fair criticism of a respected manufacturer. If CM told him that the inverter went to 60Hz with FSPC and EfraEna disabled he should have known that DC coupling was not the issue  banghead He got it wrong or CM never told him that, whatever, he's just one of many advisers there.  My phone calls to them have supplied me with all the info I needed and they replaced a 4 1/2 year old inverter FOC without a quibble.

PHONE SMA NOW BEFORE SOMETHING GETS FRIED

Sorry to have upset you, that wasn't my intention; I have the greatest admiration for all your works, and the effort that you put into them. (I'm not modern, probably older than you.)

I have no idea if the SMA man's response was correct or not, but you said that, since you had reduced the external charging current,  the issue hadn't recurred, which makes it credible at least. If that is the reason then it's probably a bug, which one would hope that SMA will acknowledge and fix.

Don,t worry Billt,
                  Clockman will be back with a fresh set of batteries. He is flat out digging at the moment which is exactly what I should be doing right now.

Hi CM
I think the part of the problem about getting information is most of the people on the help desks know the basics and how to fix/reset for "normal" usage. The designers design a wonderful bit of kit that will do loads of different things but for 99% of the customers they will only use the basic functions. As soon as you start using the equipment for something outside the "norm", although within the design of the equipment a lot of people on the help desk come to the limit of their knowledge and in most cases are unwilling to admit it.
I am having similar problems on my boiler. I have used some of the functions listed in the brochure and part of it doesn't work as described. Phoned up and was told no one uses that function on the boiler!! and have never been asked the question before, I am still waiting for them to find someone who knows how the extra functions work.
There will be someone at SMA who will know how to prove/test what the problem/conflict is, it is just the matter of finding them. You just have to push to get to the right person. As everyone says surely it is in SMA's interest to get it sorted.
Good luck
Iain

Hi 'billt', No problems, and after a good nights sleep and a bit of sunshine.........

But your points are very valid. genuflect

'Biff' I am having to come in for cups of tee tea, its the ruddy wheelbarrow pushing, a quick calculation puts the hole at about 160 barrows of sub soil to move 50 meters away. faint

Youngest at home with me at present rushed him to the emergency dentist, rear top teeth smashed in, sent home from school Wednesday, and he is only 8 years old, Mrs CM away working somewhere but at least she screamed on Facecloth and a young Spanish Dentist took pity.....

'Mostie', Yes its all a bit wishy-washy what SMA have been saying.

Thanks, 'Iain' good to know that there are other nutters/good folk pushing boundaries etc.


'Paul',
I have tried the SMA contact line, its always busy for me, I tried there Service email technical enquiry but my SI serial No is not recognised.

I have sent them another email, this time ASKING FOR THE DC COUPLING amperages the SI can take, and THE MAX DC VOLTAGE the SI can take with my 48v batteries.

I thought this way I am asking for technical information, and can modify my system accordingly and not just keep complaining.
