Dual Strings monitoring KW

Mar 15, 2014 at 1:58 AM
I have two strings on my inverter and I looking at a way to monitor them both separately,
testing with two config's at the moment

./SMAspot -u -sp0 -nocsv -v -cfg./SMAspotDC1.cfg
PVoutput=1
PVoutput_SID=27737
PVoutput_Key=XXX
VoltLogging=DC(ST1)

./SMAspot -u -sp0 -nocsv -v -cfg./SMAspotDC2.cfg
PVoutput=1
PVoutput_SID=27738
PVoutput_Key=XXX
VoltLogging=DC(ST2)

I see data like this at the command line
DC Spot Data:
String 1 Pdc:   1.528kW - Udc: 217.00V - Idc:  7.045A
String 2 Pdc:   0.396kW - Udc: 240.84V - Idc:  1.649A
But yet I see data that looks to be both strings together

If this should be the case, your Udc graph should have values around 450 V which is not the case...
The best way to check this is to enable spotdata logging (remove the -sp0 -nocsv arguments) and compare the contents of the csv with pvoutput

Be aware that pvoutput rounds the date/time to the nearest interval (depending on your pvo configuration - in most cases 5min)
So, data of 10:57:02 will be shown at 10:55 and 10:57:32 will be at 11:00

I also have the same request/problem.
I have 2 strings on my inverter, 1 for the PV's without shadow and 1 for the PV's with low shadow.
Now I want to see the difference (on 1 day, but more important during the year).

I have setup 2 systems in PVoutput, (String1 and String2).
But I cannot find any settings to export Pdc1 and Pdc2 separately. (The setting djenglish is using is for the Voltage)

So my request is, is it possible to add a config option to set the string you want to export ?
(with that you can create 2 config files, 2 scripts and 2 lines in the cronjob.)

And last but not least, thanks for the product !

I believe the EToday is uploaded, It would be nice to have:

1) EtodayPdc1, ETodayPdc2 in the csv file
2) a settings which let you choose to upload Etoday (default), ETodayPdc1, EtodayPdc2

This way you can have your total system, String1 and String2 in PVoutput (and in you csv files)

This is not easily done with the current version of SMAspot.
EToday and ETotal are the energy counters maintained by your inverter.
If you want to upload Edc1 and Edc2, SMAspot has to calculate it based on average power value during a specified amount of time. Since SMAspot is getting spot values instead of average values, it's almost impossible (like I said, with the current version)
