Exceptionally high value derived for total_pac about sbfspot HOT 18 CLOSED

logfile is ok, but can you also provide the SMAspot log (-d5 -v5)

Hi,

here is the file with the requested output.

Thanks, but I need the end of the day log where it goes wrong

Hi
Will try to run it this evening. Can I somehow run it automatically as I am not sure when it will occur.

Hi,

I tried to get a log around the time the error used to occur in the last days. I had the log created automatically at 19:40 and 19:46 yesterday.

According to my log from my home automation the error occurred again at 19:38, so I hope the attached extended log (-v5 -d5) contains information regarding it.

I also noticed in the last two days that the value for one of the strings sometimes returns a really high value in the morning.

Hi Martin,
sorry to bother you, but when the problem happens at 19:38, the log of 2 minutes later will not have any useful data.
I really need the log of the exact time the problem occurs. The best way to do this is to activate the logging for the whole day (or at least some time before you expect the problem)
Just add -d5 -v5 >>mylogfile.txt (the >> will append all the output to the file)
This will create a rather big file, but you can cutout the part we're interested in

regards,

Hi sbf,

no worries at all. I appreciate a lot the time that you invest in offering this free tool and in supporting users such as me.
I thought that the log might cover the data from a wider time range. I altered the function that is creating my current logging and I am now also calling the extended logging to a file at the same time.

Hopefully I will be able to provide a sufficient log file tomorrow evening.

Hi,

I had the extended logging executed alongside the normal logging.

According to my normal logging string_2_pdc delivered a value of 56.897 at 6:57.
I have attached the extended logging file.

from sbfspot.

[martinschmm@6/04/2014]
There was another odd value at 19:57 for total_pac which returned 28647.969.

I also attached another log file for this. Both log files might contain also the logging from 5 minutes before or after the error occurred.

Hope these log files can help locate the problem.

It looks like an old bug has slipped in...
Pdc should be divided by 1000

DC Spot Data:
	String 1 Pdc:   0.007kW - Udc: 568.97V - Idc:  0.014A
	String 2 Pdc:  56.897kW - Udc: 568.97V - Idc:  0.001A

from sbfspot.

[SBF@7/04/2014]
Same for Pac (100 times too high)

AC Spot Data:
	Phase 1 Pac : 9654.528kW - Uac: 232.08V - Iac:  0.416A
	Phase 2 Pac : 9869.154kW - Uac: 222.78V - Iac:  0.443A
	Phase 3 Pac : 9656.600kW - Uac: 227.75V - Iac:  0.424A
	Total Pac   : 29180.281kW

Hi sbf,
the interesting thing is, that both errors occur only once a day. The String PDC thing always in the morning and the total PAC always just before the production stops.

Haven't checked if its always the same time but I would bet on it.

So if it is a known bug I guess in one of the next version there will be a fix for it, will it?

It occurs just before production starts and after it ends. The Pdc value reported by the inverter is zero, but Udc and Idc aren't. At that time the power is calculated.

SPOT_PDC2   : 0 (W) Sun Apr  6 06:57:00 2014

SPOT_UDC2   : 568.97 (V) Sun Apr  6 06:57:00 2014
SPOT_IDC2   : 0.001 (A) Sun Apr  6 06:57:00 2014

DC Spot Data:
	String 1 Pdc:   0.007kW - Udc: 568.97V - Idc:  0.014A
	String 2 Pdc:  56.897kW - Udc: 568.97V - Idc:  0.001A

I'll fix this in the next version, but in the meantime, you can set this parameter in the config file:

CalculateMissingSpotValues=0

[martinschmm@7/04/2014]
Hi sbf,

thanks for your help.
Is it sufficient so simply change the parameter or do I need to restart/reload anything as well?

Is there any information mechanism (eg mailing list) to inform about updates that I could subscribe to?

Changing the setting is enough.
On the download page you can click on the notification icon. ("Release notifications are turned on")

While looking into the logs, I noticed only now you're using V2.2.11
This issue was fixed in V2.4.0
So now you have 2 options: upgrade to 2.4.2 or using the CalculateMissingSpotValues=0 option

Hi
I thought I was running the latest Version. Only installed it the other week. Seems like I was wrong. Will update asap.
