Title: Proven 6kw Turbine / SMA Windy boy Inverter Advice sought...
Post by: jonsamcor on April 16, 2019, 05:08:24 PM
Hi I am a noob from Co.Down….. Please excuse my lack of knowledge …..but I can find no one locally to give me any help or information ….

I have a Proven 6kw Turbine on (what I think anyway) is a good site, serving my home its in the Drumlins of Co.Down BT25 postcode. Its about 10 years old

I had the turbine serviced about a year ago by Kingspan who I learnt had bought Proven (who I have just found out have off loaded the Turbines to SD Wind) The service guy was from Scotland and great actually....I took the day off and learnt a bit ...but it was not cheap....

Could someone show me a link to a good service schedule for this type of turbine ? i.e. what needs done and at what intervals ? (The last one had lots of grease and fully replaced the springs among other things)

The Inverter is SMA Windy Boy (which I now know are not made anymore) What is their lifespan ?

Is their a Forum section where I can Post figures re KW/H to get a handle on what it should be producing ?


Thanks Jonny

Hello Jonny and welcome to the forum,
                                Our Proven Expert should be along shortly. He might be parking the ferry or feeding the pigs but he should not be long.
  I was quite surprised to hear that Kingspan sold out to SD. You should not have anything to worry about. The modern Proven are very good and live long useful lives.
 There are quite a few off gridders living not far from you. We have a member called Woody and he is big into wind turbines. I think he is only about 30 minutes from you.
 I used to have all his details but I will look it up and see can I find them again but he drops in regularly and will probably offer to give you a hand. Very helpful chap.

Great .... thanks 🙏
My post code is BT25 I’m in the foothills close to Dromara....
There is and has been for the last while a constant loud humming from my control panel, I have had it before on and off and assumed it was a normal operating occurrence....
But now it’s constant....it seems from the Windy boy to be still going ok, but it is throwing up “Disturbance” messages which I have not noticed before in 10 years.....
My last electric bill was double what it was for Winter ....to me it’s just a hunch that somethings amiss ..
Thank you for replying

The windy boy tells me the energy total produced is 75,000 kw/h which over 10 years = c. 20 kw/h per day on average...?

However in the past few days when I have noticed the “constant hum” the energy produced is like 1.3 kw/h and has been seriously windy for several days .... which adds to my hunch something’s not right ....

Hello  Jonny and welcome.
It is quite feasible to service the proven yourself. Do you have the kit to lower it yourself?
I'm sure Paul will be along to help shortly.

If any of the experts pick up on this thread let ping a reminder …. I don't think the issue is with the inverter more the control panel ….(but that an un-educated guess at best)

Can you provide some more information about your installation. Photos, schematics or just a laymans description of the turbine/wind interface/inverter would be useful. You may have a standard (for the time) Proven grid-tie set-up, you may not.

The Inverter is SMA Windy Boy (which I now know are not made anymore) What is their lifespan ?

Depends largely on their individual use I would imagine. 10-15 years is not an unreasonable expectation - SMA have offered extended warranties on their inverters for much longer which suggests some confidence. I have read of issues with the original Windyboys but not sure how valid they were.

There is and has been for the last while a constant loud humming from my control panel, I have had it before on and off and assumed it was a normal operating occurrence....
But now it’s constant....it seems from the Windy boy to be still going ok, but it is throwing up “Disturbance” messages which I have not noticed before in 10 years.....

Although my turbine is of a similar age and ex-grid-tied I have twin WB 3000s so would not wish to guess what your inverteris telling you without knowing the exact model. Do you have a manual for the Windyboy? If not you can, eg, download this (WB 6000) from the SMA website:
https://files.sma.de/dl/5661/WB50_60-11-FE4105.pdf
The manual will give you a basic fault finding process based on the LED status and error messages. First impression (since you seem to imply it reconnects itself without your input) is that the inverter is variably disconnecting from the grid due to grid conditions (AC side) not meeting the required criteria (voltage, frequency etc). Whether that is an inverter issue or something external would require more investigation but for a start you should establish what the pattern of disturbance is and what the associated error messages are.
Humming (and I assume you mean from the inverter itself when you say control panel) is not necessarily an issue. Mine do it all the time as grid frequency increases and the inverter prepares to back off - note however that mine are operating rather differently on a standalone grid with an intentionally fluctuating frequency.

Sadly few people publish turbine output figures. Both Paul (the resident expert) and I have published data on this forum for our own Provens. I would suggest your 10 year total output points to a respectable, but not high, return. Everything depends on your particular local conditions so direct comparisons are not very helpful. If you have local (and I mean local to you, not the general area) wind speed records of some kind  you can make a rough estimate of what you should get. I can give you comprehensive data for mine (down to 5 sec intervals if you want!) but we have unique conditions so what you could make of it I don't know.

People have different opinions about the maintenance schedule for a Proven. Hugh Piggott has a good description on his website of a service routine and I'm sure Paul will elaborate on his own website coverage. Personally I think it depends on what sort of conditions the turbine is subjected to although there are disaster stories for all circumstances. I lower mine for at least the basics of greasing, bolt/fastner checking and slip ring cleaning at least every two years but have been in the situation of watching things deteriorate within a year of servicing! The circumstances are covered in a another topic in this section of the forum.

EDIT - drat some more info since I typed this but posting anyway!

Thanks again I went out and took some pictures and will upload later...

My site is really good for wind (I can tell by the number of commercial level turbines I can see from my site) I will take a picture it was foggy this morning there are probably around 10 within a couple of miles


Re the inverter / humming issue / disturbance message I think I might have worked it out... but only think....

One of my GSHP burned out its soft starter (again....) the engineer patched it up as a temporary fix until I decide what to do (its being ripped out) so the main unit has no soft start and when the house calls for heat/hot water causing the pump to come on there is a big load required - the lights in the house flicker etc …. this in turn causes the "disturbance" message on the inverter which stops working and generation from the turbine stops and causes the constant humming on the control panel ….

Does this sound plausible ? 


Title: Re: Proven 6kw Turbine / SMA Windy boy Inverter Advice sought...
Post by: Ted on April 18, 2019, 02:40:11 PM
The spike could easily be throwing the voltage outside the inverters spec. causing a reset. But it should be running normally again within 15 minutes. Does the GSHP turn itself on/off very frequently?


Title: Re: Proven 6kw Turbine / SMA Windy boy Inverter Advice sought...
Post by: jonsamcor on April 18, 2019, 04:52:21 PM
Yes that's what appears to be happening.....
GSHP is linked to stats in the house the problem giving one heats the water and I think the upstairs underfloor so when a zone drops below or water needed on it comes (I think) it should be programmed to do most of the heavy work heating in the economy 7 hours but that programming could be shot to hell after the last meltdown

Hard to say as dependant on water usage and outside weather but it probably comes on a couple of times per hour

I will take a better one at the turbine base
Today normal to low wind 13kw/h...... probably because the girls are away therefore no hot water demand, and it has got way warmer so less need for the pump to come on and consequently the inverter to cut out ?
Well that’s my theory ......


Title: Re: Proven 6kw Turbine / SMA Windy boy Inverter Advice sought...
Post by: Countrypaul on April 18, 2019, 06:59:45 PM
If the girls are away could you not turn the HP off completely for a while and see if the WT functions as you think it should?  At least that would give a much more positive indication of whether the problem really is caused by the HP.

Jons,

As you haven't mentioned it, i have to ask.  Do you have a buffer tank installed between the GSHP and UFH ?,

I would expect my Heatpump to start 2-3 times per night (at most) rather than per hour.

Yes - as per Ted above. Note though that the inverter message should pinpoint the precise AC side "disturbance" that is bothering it - voltage is not the only possibility. Are you not able to cycle the display to give you the full error message?

The humming from the wind interface (control panel as you call it) is quite normal if it is a standard Proven unit (looks like it) when the inverter disconnects. The Turbine will continue to run quite happily, but maybe a bit noisily, unloaded but….. these interfaces are not very sophisticated as standard and although generally adequate for a Grid-tie situation (where there is seldom an inverter AC disconnect) they do not really provide over-voltage protection for the inverter (SMA in particular). This could be potentially fatal for your inverter. Since you have not mentioned any "DC disconnect" shutdown issues I guess your turbine is not producing at peak and/or perhaps is just fluctuating smoothly. It would still be prudent to eliminate the AC side "Disturbance" at the earliest.

Hi Jon.
       A buffer tank is a reserve tank or a storage tank for warm water to be used as backup. Most renewable energy set-ups call them thermal Stores. I am sure that my definition could spark debate. But debate is good. Years ago some plumbers referee to expansion vessels  as buffer tanks but that was not correct either.
 Thermal stores are normally  very heavily  insulated.
              Biff
  There are some very posh modern S/S thermal stores on the market at present. These can do all kinds of complicated moves. Well worth reading up on. In fact modern thermal stores are an absolute necessity to be able to take full advantage of our renewable energy harvesting efforts.

What does a buffer tank look like ?


Most systems have a water cyliner, say about 150L either between the GSHP and UFH or on the return leg of the UFH,  this is seperate from your hot water cyliner.  Its there to
prevent short cycling (constant on/off of the GSHP) and possibly give a 'boost' when heating is needed, as theres a store of water at say 30 degrees ready when required. The larger volume of water in the system limits the stop / start .

If there is no buffer then this could be the problem / solution,  as the soft start may last 10-20 years if the GSHP was only turning on 6 times per day rather than say 20 times.

Ive seen dimplex comercial installs that dont have a buffer, so it may be possible to adjust flow rates etc to have the system work without a buffer, but most systems
have a buffer.

Id be wary of refigeration engineers and heatpumps,  theres a risk that all they can service is the compressor, there ok for regassing but might not be aware of how the system should run.

PDF who posts on here has very good knowledge of GSHP, from what ive seen of his posts, he may be able to advise further.

Here is a pic of my system installed in Dec 2015, so has nearly completed 4 heating "seasons". so far, hoping I'm not speaking too soon, 0 maintenance.

I have labelled the DHW tank and the small buffer tank. My heatpump is the non "inverter" type so the compressor is either on or off. In "normal" average conditions it is on once every hour and a half or so and runs for approx 20 mins. It does all the heating and DHW in the cold months. Over holiday periods when the kids decend with their partners there are up to 10 people in the house all using showers etc and there is never a shortage of hotwater, the large tank helps. Like others I can only think that the soft start controllers are failing due to the number of starts the pumps are doing. There are no buffer or DHW tanks visible in your picture just expansion vessels (required for unvented systems). Do you have a DHW storage tank?

Again. as previously mentioned, refridgeration engineers may be able to fix the heatpump but are unlikely to understand the whole system and ensure it is set up and running correctly. With my system it took nearly the whole of the first heating season to get everything adjusted correctly so that the house was always a comfortable temperature and the system ran as economically as possible. I know it hasn't been a cold winter but consumption this year (year 4) is over 30% less than in the first year - and the first year did not start until mid December!

I think DonL mentioned in another thread that heat pumps work best on long runtimes at low temperatures, mine system runs 24/7 in the heating season, no timers,  and is so economical plus the house is always warm. In my opinion the problems start when people try to operate them like a gas or oil boiler system.

Great photo Marshman, i envious of the space you have.  my system was a last minute addition to a new build in 2003, so everything was shoehorned in, it a **** to work on.

Im still adjusting my system /  timimg / flo temps after 16 years   ;D,   the comfort was always there but each adjustment gives a bit more economy, adding solar , turbine etc.

I currently lift the room temperatures at night by a degree over whats required , this seems to give a longer run time at night on night rate electricity and reduce running
during the day to an hour or two at most, if at all. it seems to work for me.
I also run the bedroom areas for two hours at the start of the night when the flow temperatures are low and then concentrate on the living accomodation for the rest of the night (my house is upside down, so that may not work for all)

The comment on not treating it like a boiler, is soo true.  the systems appear to be designed with fine margins, Slight changes to flow temperatures / times make a difference, but it may be a few days before you see the final results. If it works like an oil boiler then its wrongly sized.

I understand the constant start ups are also very sore on the compressor and i was also advised by an electrical engineer that a soft start is failing slowly with every use, thats the nature of them (could have been due to arcing/pitting).  Can anyone confirm that or correct it ?

jonsamcor if you had a buffer tank you could heat it with the power from the proven turbine and you wouldnt even need a heat pump at all.

No buffer tank .....
Just a couple of DHW tanks in the house ....a problem I think I have is when the GSHP goes down the water heated by the vacuum tubes gets taken into the UFH ....I think ....just because when pump has been down and it’s a great day for solar  I don’t have hot water.
The engineeer was trained by Dimplex re servicing their pumps so knew what he was at
The installer for the new one coming Ecoforest is local and has impressed me with his knowledge to date ....
There is no soft start in their pump ..... we shall see .... but will ask the question re a buffer tank

You should have a buffer tank with a couple of immersions in the bottom then you could divert the electric from the turbine to the immersions instead of exporting it. All our heatpump installs have a buffer tank.

I had a look at the Ecoforest literature,  they say they dont need a Buffer tank due to the inverter technology, so maybe Dimplex were the same.  Either way
the constant starts point to another problem in the system.
The commercial dimplex install i mentioned had similar initial problems with Domestic hot water bleeding into the UFH due to a faulty one way valve in the system pipework.
Just make sure the new installer is aware of the problems and get a schematic of thier proposals. Theres a risk they will simply replace the heatpump and blame
any probelms on the existing system, they really need to take responsibility for the design of the existing system.

The Dimplex heatpump in that install gave no problems and hasnt been serviced for 7 years

jonsamcor,

You say there is no soft start in the Ecoforest heat pump, surely if it is inverter driven and variable then it must have a soft start almost by definition?

Thinking back, i has the same problem with my UFH using the DWH and solved it by putting a motorised valve on the DHW supply, which was activated by the hot water timer, so there could be no unintended flow through the HW Cylinder. This wasnt much of a problem initailly as i didnt have solar. it became noticable when i went to bed with a tank of 60 deg HW and woke up to a tank of 35 deg HW. Your installer should be addressing this without being asked.

It sounds to me like you may not be too far from a good system, but you need more facts on what the new install includes. Modifying the existing system
to suit the requirements of the new GSHP is something I would insist on as part of the price. i know im cynical, i wasnt always !.

I just envisage changes/upgrades that you will be charged for if problems arise, Hopefully not.

Appologies to the Turbine people for hijacking this thread, but it appears that the turbine problems may be easier to sort if the GSHP is running
correctly (and with a soft start ?)

Post by: rogeriko on April 20, 2019, 02:21:57 PM
On an Eco-Forest heat pump the inverter drive IS the soft start. The compressor starts very slowly and builds up to full power (if required) over about a minute. They have seperate outlets for DHW and heating with a common return. You set the temperatures on the control panel and the unit does the switching between DHW and heating. I hope the installers know how to replumb the system!!

The pump house adjoins the garage, there is a room above the garage and whilst being built I saw that there was no heat to it should asked for a couple of rads to be put in take the chill off in bad days.....

So I guess that they didn’t think there was sufficient room in “pump house” for buffer and they put it next door in the garage ...... I had just assumed that it was stuck in there because I had asked for heat above the garage whilst they were well on in construction and it was a bolt on ......

I will put the issues re solar water etc to the new guy.....but I will get you lot to mark his homework......
I am pretty certain now that the cut off /humming is a result of the soft start being removed ....
I have witnessed it a few times in the garage today ......
Hopefully the new pump will cut that out .....
Today was the most beautiful Easter Sunday I can remember....... just wish I had a load of PV panels on my south facing garage roof .....
Again thank you 🙏 for the help
9-5 I’m a Solicitor (don’t hate me) if I can help any of you I will ask away ....

This humming.  When does it occur? Does the motor actually start and operate normally?  I ask because any heat pump with hard start needs to have the compressor off-load at start up. 

A domestic fridge or freezer has an overload cut-out for cases where people turn the compressor off and on in too-short a period.  The motor will then try again, to start, after the overload has cooled off.

I’m pretty sure the humming comes from the control panel of the turbine and happens when the inverter cuts out because the gshp (with no soft starter) comes on and causes a disturbance and I guess it is because the turbine is still producing ? After a while of the inverter coming back online and working normally it dies down greatly, hopefully will not be an issue when the gshp is replaced .....

I have a Proven /SD wind sd6 6 kw turbine that was installed in 2007.
The control board has burned out, and I need a circuit diagram to repair.
Anyone got one they can upload?
The number on the board is

EC06-CB1-0515 Rev C

Give SD wind a quick call, I've always found them really helpful, still the same folk as Proven days. I've a few boards here, but none to match that number.
