Multi Inverter Support - Only one stored in the database.

Topics: 5. Support

Hi,

I've got two SMA 3000TL-21 inverters, and am using SBFspot via bluetooth to monitor them. I've enabled multi-inverter support, and all seems well, except that in the database, only the data from one of the inverters is in the daydata table.

This seems a bit odd to me, since the spot csv file contains data for both inverters, and both inverters are listed in the inverters table.

Any ideas? ( The system was only installed yesterday, in case it makes a difference )

Try to run with verbose logging (-V5) and look for errors in the output.
Are the csv files OK? (compared to those of Sunny Explorer)

All looks ok.... apart from one thing which is probably the cause that I've only just spotted - the time isn't set correctly on the inverter - its set to 2008! The time's set to sync ( using SBFspot ) to the computer but I'm guessing that since this is the second inverter in the network it's not happening.

I haven't set up any of the SMA software etc so I guess I'm going to have to work out how to change the time on it!

Yep, that was it. Works fine now.

Not sure whether you'd count failure to sync the time on all inverters as a bug?

Hello,

I have a similar case.
I use version 3.1.2 of SBFspot.
I have two SMA inverters.
I followed the steps in "SBFspot V3 was installed Raspberry Pi EN V1.1"
I have configured "MIS_Enabled = 1"
PVoutput the Upload Settings is: PVoutput_SID = 2120077323:1234,2120077365:1234
Here are the creation of CSV for both inverters:
03/12/2015 09: 54: 45; SN: 2120077365; SB 2500HF-30;2120077365;936,000;0,000;2,166;0,000;434,500;0,000;836,000;0,000;0,000;3,578;0,000;0,000;233,760;0,000;0,000;936,000;836,000;0,000;0,242;10791,718;49,990;17696,732;16839,068;0,000;Ok;Fermé;29,090
03/12/2015 09: 54: 45; SN: 2120077323; SB 2500HF-30;2120077323;950,000;0,000;2,320;0,000;409,510;0,000;878,000;0,000;0,000;3,748;0,000;0,000;234,280;0,000;0,000;950,000;878,000;0,000;0,488;9912,483;49,990;17617,535;16686,034;0,000;Ok;Fermé;29,720

Here the log Upload:
[9:55:31] INFO: Uploading datapoint: 20,151,203.09: 50,9912412,804 28.6,234.57 ,,, => OK (200)
[9:55:31] INFO: Uploading datapoint: 20,151,203.09: 28.234 50,10791660,636 ,,, => OK (200)

But only one is sent to PVoutput!

In another discussion, we talk about as this:
It can be shoulds HOWEVER, by Modifying the vwPVOdata (SUM / GROUP BY)

What is that? where that is?

Thanks for your help.

My issue was that the date on one of the inverters wasn't set, so that the datapoints referred to some time in the 1980's I think. However, you say:

PVoutput the Upload Settings is: PVoutput_SID = 2120077323: 1234.2120077365 1234

Not sure if this is just you typing rather than a cut and paste, but the "1234" should be a PVOutput system ID, and needs to be different for the two inverters. I.e, you create three systems in total on PVOutput - one for each of your inverters ( which are the IDs you use in the config file ) and then one which is a "parent" system which aggregates the data automatically, so more like

PVoutput_SID=2120077323:1234,2120077365,1235

if your systems were 1234 and 1235 ( the parent system will have another different ID. )

If you want to combine your inverters locally then that is a different problem with a different solution.

Yes it should read:

PVoutput_SID = 2120077323: 1234,2120077365 1234

while the data is successfully extracted, a single inverter is shown PVOutput.
I want to see on PVOutput combination (one grafic) on both inverters.

It has already worked before September 2015.

That's why you create the third ( parent ) system - it combines the two individual ones. See my system here:

http://pvoutput.org/list.jsp?userid=45167

That's my parent system which shows a combination of both inverters. However, if you see under the graph where it says "3 Systems" and click it, you'll see that it lists the other two. THOSE are the ones that the uploader uploads to. You can't upload two sets of data to the same system because one will overwrite the other.

@Cortomaltese
Yes it should read:
PVoutput_SID = 2120077323: 1234,2120077365 1234
You can't upload 2 systems to 1 PVO SID - The last one will overwrite the data of the first system
Like "sidepipe" said: you need 3 systems on PVO: 1 child for each inverter and 1 parent to combine the other children

3.0.3 version group data, right?

ok, how do?
Settings
registred Sysytem
Add System
PayPal :-( :-( only 1
Change PVoutput Upload Settings
PVoutput_SID = 2120077323:42242,2120077365:42241

Data Aggregation:
set the parent of the two inverters.
save.

no data in the two inverter PVOutput ... ???

And how to stop sends the temperature of the inverter?
I set the automatic Uploads a IMOUSCRO12 Weather station
Thanks for your help.
Dec 3, 2015 at 8:13 PM
Latest version is OK: V3.1.2
Is the data OK in the database?
To stop sending inverter temperature, see "tweaking" chapter in this document: https://sbfspot.codeplex.com/downloads/get/1441111

thank you for help,
I think it works now.
