@beaud
I’ve read a few of your posts, I would like to know what push settings you have for your inverter and meter.
How accurate is your pvoutput compared to solarweb with these settings?

cheers mate

Hi,

I am using the following push settings;
Inverter Push - Interval 5 Min
Server: pvoutput.org:80
Upload file name: /service/r2/froniuspost.jsp?sid=&key=&nodayenergy=1

Meter Push - Interval 5 Min
Server: pvoutput.org:80
Upload file name: /service/r2/froniuspost.jsp?sid=&key=&v6=Voltage_AC_Phase_1&auto=1

Generation and Consumption Data is pretty good, Export, Import and Self Consumption, not so much. My Numbers for the month of December (in kWh).

I am still waiting on a bill so I can compare some figures with those on a Bill, I have a nodered flow feeding data into my Home Automation software (Domoticz) and configuring that to feed back to pvoutput is on my list, but its a long way down.

#101

@beaud Thanks for the reply…

I’m using very similar settings which have shown to be quite accurate.
I have had 4 ‘test’ IDs going with slightly different variables to see what’s most accurate.
Over the last 2 full days I have been within ~0.1% on Consumption / Imported / Exported / Generated comparing Fronius data to PVO.

5 min pushes
Inverter: &v3=None&nodayenergy=1
Meter: &v6=Voltage_AC_Phase_1&v4=PowerReal_P_Sum&auto=1

Actually found that using &delay on the meter gave me less accurate information. (but still within ~0.01-2%)

I found using &v3=none actually made a (good) difference, even though using auto=1 should not take into account v3 (so I read somewhere)
&v4=PowerReal_P_Sum seems to give more accurate ‘snapshot’ power use data, but at the end of the day doesn’t make much of a difference.

See how it goes over the longer term.

#102

I did have both &v3=none and &v4=PowerReal_P_Sum at points while trying to diagnose, I’ll add those back and see if my accuracy improves, to be honest I have sort of given up of PVOutput giving me quality RIO data, still great for comparing systems and tracking production and consumption.

The Solarweb Premium Trial, is just a free upgrade to premium in Australia, it’s not really documented anywhere but if you go though and sign up for the “Trial” its good for 20 years.

From mine.
You are currently a Solar.web Premium member. Your membership will be renewed on 09.12.2037.

Once a premium member and with the Tariff data entered it give pretty good ROI Data.

#103

So after a few more days of data, it sees those values have had some effect, but still plenty of difference, just on different numbers, maybe a little more spread?

But I have noticed that on a clear day, when output is constant the number are very close, if there is any sort of cloud cover, where production drops, this seems to mess with the numbers, I did read in a thread somewhere that this was an issue with split arrays (which I have) so that might be the reason why I am seeing my variations, I’ll have to look into it more.

The last day (18/01/18) was nice and clear, and the graph is nice and consistent, on the other 2 days the consumption drops to 0 on a number of occasions, which is clearly not right, the drops seem to co-inside with production drops.

Hi just a thought,but have you checked to see all the time stamps line up to the second, thats your computer,fronius push in the inverter and also you second device if using one, i have noticed my figures are off when my inverter time is out by more that a few seconds ,i have seen it up to 3 mins out,and i have found that auto update for time is not good enough on the inverter.:slight_smile:

I noticed there’s a firmware update (fro28500.upd) just out for my Symo and other Fronius inverters. I’m hoping it means I can remove the ‘overnight’ patch in my Push script, since there’s possible mention in the changelog. However, I’ve yet to pluck up the courage to install it. I’m hoping some other ‘bleeding edge’ firmware enthusiast will lead the way :wink:

[EDIT] It got the better of me, so I updated to fro28500. It took about 30 minutes which seemed longer than previous updates, but it went through without any intervention on my part, reconnecting to the networks once it finished. After removing the ‘overnight’ patch from the Push script, the inverter’s daily production figure is (still) almost exactly the same as PVOutput’s - so far, so good.

#106

Hi beaud, I am yet another new comer struggling with getting accurate figures. I am not yet a subscriber so cannot use auto=1 as yet.
However some figures are way out.

Inverter push = /service/r2/froniuspost.jsp?sid=your_sid&key=your_key&v3=None
Meter = /service/r2/froniuspost.jsp?sid=your_sid&key=your_key&v6=Voltage_AC_Phase_1&n=1
figure: SolarWeb PVOutput
Generated 7.37 7.39
Export to grid 5.58 2.97
Consumption 3.74 7.15
Import from grid 2.28 2.73

Is using auto=1 the only way to get close to accurate

Interested to see what URL stings you are now using
Fronius Primo 5

Thanks in Advance,

Mike

@samwest, I am interested in you comment about Feed-in-Point. I had an energy issue that took out my Fronius meter.

Up till then all Solarweb data was fine and I was getting correct data for teh "Return of Investment " and “Expense” graphs in Solarweb.
There was about a week without Meter reading until the new meter was replaced.

Since the day the new replacement meter was installed - most of Solarweb data appears correct, however, the ROI and Expense tables now only display savings and the data value appears incorrect - much more that it should be. Infact the savings figure are the same for both.
Could this be to do with Feed-in Point setting do you think? Wondering if you experienced the same?

Oh, I should add, I dont have the password for that part of the settings in the console so cannot see the value.

Thanks,

Mike

#108

My current settings are;
Inverter = &nodayenergy=1&v3=None
Meter = v6=Voltage_AC_Phase_1&v4=PowerReal_P_Sum&auto=1

I couldn’t get it work without subscribing and using the auto function, but some other say there figures seem to match. But as I mentioned above, I still see some small discrepancies in import\export values.

I am just about to remove the nodayenergy=1 value, as I updated to fro28500 a couple of days ago and the inverter now seems to report day usage as expected.

Beau

#109

Thanx Beau,
Yes, I also have done the update so did not bother with the nodayenergy value.

Two of my figures are well out.
Consumption, albeit this looks like it is adding the from solar and from grid together as one value, and export
Export is twice the value of the true data.

I may have to subscribe soon if I plan on going down the live path.

Thanks Mike

#110

Hi Beau,
Just did a quick test with your settings but with &n=1 rather than auto=1 and all the figures are relatively close with exception of Consumption is still close to the addition of direct + grid consumption - not sure the impact of this value over all or if this is the correct value for that field.

Thanx again for your reply.

@beaud, I have done some more work and testing this arvo and for now, the live view is pretty close, not perfect but data is close enough to serve its purpose.

Thanx for your help.

No Problem, Good to hear.

Make sure you also sign up for the premium trial on solarweb, as I mentioned a few posts back the trial is 20 years, pretty much free in Aus. Between the 2 I have all the data I need.

Beau

#113

Yea, the installer was fantastic and set all that up for me on installation day. All was looking good until about 6:45 this morning and now the data has gone off target.

Consumed is almost double true value, export is like half and consumption is more than double the true reading.

Solarweb is great but PVOutput realtime gives extra realtime data when trying to identify power leaks.

From what I have read on the forums, the only way to get a truly consistant and accurate data stream is to donate and use auto=1.
Having said this - since my meter replacement Solarweb no longer show correct data under ENERGY BALANCE/Return of Investment or Expense. There was an 8 Day period where I ran without a meter before the new replacement.
Since the new replacement meter these to graphs only show and incorrect reading of the saved value which is of no value at all.
Fronius via my installer are looking into this as we speak. Support is really very good with both.
Is it like that the new meter has not been set to Feed-In do you think?

I am done with the inconsistencies of n=1 - now a Donator and auto=1. Tomorrow will be the first full day. :slight_smile:

#115

For anyone trying to accurate data from Fronius invertor without using auto=1, good luck :smile:

Over 3 days I toiled with n=1 etc along with many others strings with only partial success. Now a donator and using auto=1 the data is accurate enough to be useful - worth the donation IMHO.

There is a few reason I persisted with PVOutput. One being I wanted as much data as possible to identify anywhere I am bleeding power. Solarweb is excellent but does not give me the real time data I want and not the running tally tables.
Its a pretty common theme in view of n=1 against auto=1 and IMHO I have to agree with others auto=1 is the only way to go.
As an example, I have had a source drawing current on an intermittent cycle over night. Turns out that the Daiken Invertor systems have a heater element in the sump to keep the oil above a certain temp with the purpose of keeping the coolant gas out of the oil as this can be explosive. Problem solved

#116

After reading these n=1 vs auto=1 opinions, and since my PVOutput has been working nicely (previous FW/overnight issue aside) and pretty much agreeing with Solarweb’s data, I figured my Push script must have included the recommended auto=1. But it doesn’t - it’s using n=1.

I subsequently edited it to auto=1, saved the change and waited a few minutes to check the results in PVOutput. Oddly PVO failed to show any consumption data at all from that point on. I switched back to n=1 and PVO went back to normal, filling in the missing consumption data.

So for me, at least, auto=1 isn’t the way to go, but I would like to know why?

#117

That is really interesting Wilburight. Are you pushing from an Inverter and meter. I expect you maybe as my understanding is auto=1 is a meter only setting.

Also I was just about to post this in a new thread. But for interest will also comment here. In the Edit System settings under Advanced settings.
You can set Net Method to Average or Instantaneous. I was told by someone that for Fronius Primo systems it is better to set as Instantaneous.

#118

You’ll need to wait till the next day for the auto=1 to take affect since it takes the start of day energy import/export data.

Enabling this in the middle of the day can have unexpected results for the rest of the day since there is already data there.
