Hello i had made some adjustments to the run command now i am getting the ERROR:solaredge:Unhandled exception: int too large to convert to float
Expecting for your response
I appreciated, thank you

Hi! Sorry for the late reply, I seem to have missed your issue. I'll try and have a look at this as soon as possible.

Can you please re-run the command with the -d flag? This will give some more debugging output. Also, what inverter are you using? I wrote this against an SE7K.

The 6553.5 values shown about indicate that the decode is overflowing. This means that the values I read from the inverter are larger that what has been allocated to store them with. I have no idea why that is the case, especially without access to that specific inverter.
The lifetimeproduction value also seems quite large. I get the feeling that in this inverters case information is read offset 1 byte left or right, causing all calculations to go wrong and report the wrong values.

Hi, i've got the same problem.
I'm new to github.

Started counting bits with help of
https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf

And changed a view dataskips
Row 63 from 24 to 22
Row 68 from 2 to 4
Row 70 from -2 to -4

And things started working

from solaredge-influxdb.

robmit68 avatar robmit68 commented on July 17, 2024

jaaphoenderdos
I did the same and follow you changes and i got it sort of working for most parts with the exception of the following items below, i am not sure if the counting bits are correct for all of them to be the same or it will need a separate count.
Let me know if you were able to check that please. i am new in python as well.

40073 AC Current phase A i get a readout (working)
40074 AC Current phase B i get 655.35 (i believe they are not correct)
40075 AC Current phase C i get 655.35 (i believe they are not correct)

40080 AC Voltage phase A i get 6553.5 (i believe they are not correct)
40081 AC Voltage phase B i get 6553.5 (i believe they are not correct)
40082 AC Voltage phase C i get 6553.5 (i believe they are not correct)

jaaphoenderdos,
i repeated most of the commands line by line in your solaredge.txt almost there except with the other registers 40074, 40075, 40080, 40081 and 40082 which still not reporting correctly.

Attached my solaredge file
solaredge.txt

jaaphoenderdos avatar jaaphoenderdos commented on July 17, 2024

Robmit68,

If i'm correct you're skipping the AC Current and Voltage part of my code. For each fase. That means that there's a shift in the byts. That's messing things up.

If you want to skip a datapoint. You need to replace this with:
data.skip_bytes(2)
For 16bit

Or
data.skip_bytes(4)
For 32bit

from solaredge-influxdb.

robmit68 avatar robmit68 commented on July 17, 2024

jaaphoenderdos,
Absolutely not trying to skip AC Current and Voltage those items are part in my script, When i try to compare your text file with mine i discovered #Register 40072-40075; 40080-40082 and 40084 are repeating after 40084 let me know if that's required to get successful readouts without shifting bytes.
Please advise thank you. I appreciate the help

No problem, i'm reading to fast.

I've made a better copy of my file. So the syntax should check out.
I will try to run your file later today. Lets check if i can recreate the problem.

Now its getting complicated. Both files work at my end...
Could you try port 1502 instead of 502? By adding --port 1502
My solaredge uses this port.

My readout from my setup:

'AC Current phase A': -630.0,
'AC Current phase B': -638.0,
'AC Current phase C': -628.0,
'AC Voltage phase A': 235.8,
'AC Voltage phase B': 232.9,
'AC Voltage phase C': 238.7,
'AC Power output': 2227.0,
'AC Lifetimeproduction': 5402255.0,
'DC Current': 3.02,

'DC Power input': 2260.9},
'time': '2020-05-21T06:10:06.248381+00:00'}

And from your file
'AC Total Current': -1870.0,
'AC Current phase A': -622.0,
'AC Current phase B': -622.0,
'AC Current phase C': -624.0,
'AC Voltage phase A': 233.8,
'AC Voltage phase B': 233.4,
'AC Voltage phase C': 239.2,
'AC Power output': 2196.0,

Attached you will find the file i copy from your last email i copied and run it on my solaredge device in port 502

i am highlighting the duplicates on the file, perhaps the file gets tampered on github i am not sure??
Thank you looking forward to get this resolve.

Thank you Agsain

Hmm,
My file has a part that doubles for some reason. My bad i guess...
solaredge.py.txt

Your inverter isn't the same as mine. Mine uses the SunSpec modbus settings.
Read: https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf

Can you update the firmware or something. Or is your device older? In that case the Original code from salberin should work...

robmit68 avatar robmit68 commented on July 17, 2024

jaaphoenderdos,
No problem i was going crazy with the file but no worries, any how let me provide the details of my solaredge PV unit below

SolarEdge SU7600H-US Single Phase Inverter, would that be i don't have phase B and C? i am so new to this with little electrical experience. PV was installed sometime late October 2018 and its running CPU: 3.2221, i saw they have 3.2225 but at this point will be trivial to upgraded.
I am using SunSpec TCP/IP Modbus protocol.

I can possibly remove some of the AC Phase B/C to no provide the wrong readings, let me know

Regards

robmit68 avatar robmit68 commented on July 17, 2024

jaaphoenderdos,
can you also help me to reconcile my solaredge.py with the correct bytes as per your comments on our communication before, let me know and help me understand the bytes read

for example in a single phase Solaredge solaredge.py file how would i start counting this bytes so i can get accurate reads from my meter and go forward from there to a successful reads, please advise.

---Commnets----
If you want to skip a datapoint. You need to replace this with:
data.skip_bytes(2)
For 16bit

Or
data.skip_bytes(4)
For 32bit

Snip sample
# Register 40072-40075
datapoint['fields']['AC Total Current'] = trunc_float(data.decode_16bit_uint() * scalefactor)
datapoint['fields']['AC Current phase A'] = trunc_float(data.decode_16bit_uint() * scalefactor)
datapoint['fields']['AC Current phase B'] = trunc_float(data.decode_16bit_uint() * scalefactor) # Needed if 3phase Current
datapoint['fields']['AC Current phase C'] = trunc_float(data.decode_16bit_uint() * scalefactor) # Needed if 3phase Current
data.skip_bytes(14) # whats this means in reference to the read
scalefactor = 10**data.decode_16bit_int()
data.skip_bytes(-8) # whats does means in reference to the read
logger.info('40072')

jaaphoenderdos,
great file i am seeing the difference on the script, i appreciated the effort, below my result.
I am using your file now to get my readouts.

The second datapoint 'Sunspec Length' is 50

Let's look at your question again.

Below the ones are failing to provide output
40074 AC Current phase B i get 655.35 (i believe they are not correct)
40075 AC Current phase C i get 655.35 (i believe they are not correct)
40080 AC Voltage phase A i get 6553.5 (i believe they are not correct)
40081 AC Voltage phase B i get 6553.5 (i believe they are not correct)
40082 AC Voltage phase C i get 6553.5 (i believe they are not correct)

Current phase B and C, and Voltage B and C aren't failing. They don't exist because it's single fase

Voltage phase A is incorrect. Judging your data. Voltage AN is blank. It looks like the N wire isn't attaged. You do have a reading on Voltage AB. Maybe that's the split fase part.

So i created a file that doesn't read the B and C phases. And registers Voltage AB. Please test.

i was looking onto your settings and the ones you send me for the grafana, but i am afraid i am not getting the same or close readout from the python scripts at least on the current power and energy today, perhaps something i missed. I am sending you the pictures taken at the same time for comparison. Lifetime energy is on the money.

The python data is correct. So it must be the calculations by grafana. I have a view questions. The letters of the question matches the letters in the picture

A. Current Power seems low. It should be 550W. Thats strange because the graph 'FNC Solar Current Power' is correct. See point E.
B. This seems correct.
C. This is incorrect. But next month is should be correct.
D. This seems correct.
E. This is about 500W. So this reading is the current power.
F. This total is wrong and doesn't say mutch. Why do you want to know this?
G. What is the formula of this one? It looks like the the sum of the current power reading. What are you trying to accomplisch?
H. It's a strange number, should be around 2A. But in my installation i'm also getting a negative reading and a strange number. So i'm not using it.
I. Voltage is in V
J, Power output is in W. It looks like the correct current Power...
K. Seems correct. I think your vertical axis is set on kWh. It needs to be Wh.

Its a slave meter. So the address shifts.
Meters base address:
 1st meter – 40000 + 121
 2nd meter – 40000 + 295
 3rd meter – 40000 + 469

Your script starts at:
reg_block = client.read_holding_registers(40069, 38)

You could try to run a second script that starts at
reg_block = client.read_holding_registers(40190, 38)

The WattNode is a threefase device? Then use my threefase file:
solaredge.py (1).txt

from solaredge-influxdb.

robmit68 avatar robmit68 commented on July 17, 2024

Jaaphoenderdos,
Correct The Watt Node it is an slave meter on the MODBUS.

Watt Node is a three phase meter but i am running an split phase in my SolarEdge as you can see to attached solaredge.py which in fact you help me a lot to get it perfect - for that i appriciated.

I had tried to rewrite the test file into a wattnode.py.txt, with the correct registers 40190, 38 but i am getting errors i am sending you the file as well.

Hmm, i don't unsterstand why you've got a syntax error.

Maybe its the length of the holding register. In your wattnode are many data point. How did you created them?
Try
reg_block = client.read_holding_registers(40190, 68)

Some other test options

  • Stop the soleredge script when testing the wattnode
  • remove the datapoint time for now. For testing we need the logging data. So we can see if we're on the right track.

from solaredge-influxdb.

robmit68 avatar robmit68 commented on July 17, 2024

Jaaphoenderdos,
Syntax errors comes after place a # or remove line from the script and it complains line after line.
i did run again solaredge-test.py without no problems

The Wattnode data points i used that from the SolardEdge MODBUS 40190 + 121 meter one

i did change the reg_block to (40190, 68) but not luck

Let me look into the watnode registers and past them on a file later

Thank you

from solaredge-influxdb.

jaaphoenderdos avatar jaaphoenderdos commented on July 17, 2024

Okay,
If you use the solaredge test file and only change the reg_block it runs without problems. Then you have a readout of the registers. The script printsout the regblock. Something like:
[102, 50, 2702, 2702, 65535, 65535, 65534, 2421, 65535, 65535, 65535, 65535, 65535, 65535, 6526, 0, 5997, 65534, 6541, 0, 4540, 65535, 9975, 65534, 266, 22512, 0, 17198, 65533, 3852, 65535, 6625, 0, 32768, 7501, 32768, 32768, 65534]

Did you get this type of printout and does it contain any data? Could you share?

If there is data, we could check if we're on the right track.

I run the test with and change the reg_block to (40190, 68) and i got results as you expected. We are on the right track. I am sharing that dat below

Nice. Data. Problem is that i can't tell what is what...

The Wattnode modbus uses 32 bit registers. So maybe one of the testfiles makes sense of the data. According to https://ctlsys.com/wp-content/uploads/2016/10/WNC-MODBUS-Manual-V16.pdf

jaaphoenderdos,
Below you will find the attached file i capture to make sense of the data, in advance thank you for your help
Regards
sample data from wattnode files.txt

jaaphoenderdos avatar jaaphoenderdos commented on July 17, 2024

Robmit,
The data doesn't make any sense, as far as i can see.

Could you create the data and give the readings in the solaredge app. So we can compare the data.

Then we'll know what to look for.

jaaphoenderdos,
Below you will find the capture i have done in a modbus poll tcp software, i downloaded from the internet, i am not seeing the data but probably you can make sense if that. let me know if anything

Thanks.
Could you send the corresponding data from your solaredge app. So we can compare the data.

Robmit,
I've seen your excel file. It seems like that your columns are correct.

So that means that we have to build one file that can readout both modbus meters.

I've made a first testfile:
solaredge-test-wattnode.py.txt

Please run this file. And make another pull with modbus poll tcp software at the same time. So we can compare.
Run the modbus poll tcp software from 40069 to 40260

If the data from the wattnode is missalignt you could change the skip_byte to correct.

from solaredge-influxdb.

jaaphoenderdos,
Above the early statement before, i have run the solaredge-test-wattnode.py.txt file you attached earlier and corrected a syntax error but is hanging without results. below you will see the output and the prompt is flashing without data

i look into influxdb and capture below after stop the working file

You can see stop of my working file and start of my working file in between the test you send me

Hmm.

It seems to hang between logger.info('Database opened and initialized') and print(reg_block). Because i don't see a printout of the reg_block.

So reg_block = client.read_holding_registers(40069, 190) must be the culprit...

I'm unable to test things on my own setup until friday. But google is our friend. Maybe it's the read timeout setting that is to short.

In the last lines there's:
client = ModbusClient(args.solaredge, port=args.port, unit_id=args.unitid, auto_open=True)

Try to add a timeout:
client = ModbusClient(args.solaredge, port=args.port, unit_id=args.unitid, auto_open=True, timeout=10)

I tried the timeout value but same result no printout and it hangs. I will be reading to see if anything if not I will touch basis till Friday, thank you for your help.

jaaphoenderdos,
I was able to get the registers with your help and a modify file you provide me for the test, attached is the file with the script and result gathered from the python script, I am not familiar with the skip bits to each register. I would appreciated your help on that. Looking forward to your input.

I validated at least one register 'M1 AC Frequency': 6001.0, 'M1 AC Frequency SF': -2.0, = 60.01 Hertz

At the end once you help me figure this thing out can we combine the inverter and the meter readings in one file
wattnode-test-fnc-results.txt
?

Thank you

from solaredge-influxdb.

jaaphoenderdos avatar jaaphoenderdos commented on July 17, 2024

Nice.
We're getting there. It took some time, but i think this is the way to go.

I've calculated the scalefactor directly in the script. They probebly never change.

So this should work:
Wattnode-test.txt

I've also tested to combine the two files in to one. And hopefully this works to:
Wattnode-solardge-test.txt

The only reading i don't understand is: 'M1 Imported VA SF': -32768.0
This is incorrect.

robmit68 avatar robmit68 commented on July 17, 2024

jaaphoenderdos,
i was able to get results on the Wattnode-test.txt file only, below the output, in other hand the combine Wattnode-solardege.txt did not work is the second output result, somehow it runs but it doesn't read registers.
i agree we are very closed to get the information on this devices, thank you for your help
Regards

jaaphoenderdos,
the last file its working now i am getting readings from the Modbus slave meter thank you very much i appreciated the time and effort.

I notice that the 'AC Total Current': -4994.0 is negative, is that normal?

Now i have to figure it out the formulas and graphs to get the information on Grafana
Thank You.

Hi,
Nice.
'AC Total Current': -4994.0 looks strange. It's a reading from your solaredge. You could comfirm by using your original script. And check if there is a difference.

If there is a difference. Please send your original script.

your welcome

jaaphoenderdos,
Thank you now all readings are correct, still working on the Grafana graphs to consolidate all new readings, it is awesome and thank you for your help. I appreciate it.

Regards

I would like to pick your brain on some of the register readings and skip bytes I am interested for the experience to help and assist others.

Can you tell me what does mean below statements and how to read them please

            # Register 40072 
            datapoint['fields']['AC Total Current'] = trunc_float(data.decode_16bit_uint() * scalefactor)
            data.skip_bytes(20)
            scalefactor = 10**data.decode_16bit_int()
            data.skip_bytes(-14)

I see register 40072 = AC Total Current,
data.skip_bytes(20) what does it means
data.skip_bytes(-14) what does it means

I would appreciate any help on this so I can learn more of the python coding

Thank You

from solaredge-influxdb.

jaaphoenderdos avatar jaaphoenderdos commented on July 17, 2024

Robmit,
your welcome,

How it works:

We read a part of the modbus, starting at point 40069, readout 38 points:
reg_block = client.read_holding_registers(40069, 38)
print(reg_block)
Your data is:
[102, 50, 2497, 2497, 65535, 65535, 65534, 2386, 65535, 65535, 65535, 65535, 65535, 65535, 5948, 0, 5998, 65534, 5960, 0, 3872, 65535, 9978, 65534, 311, 23504, 0, 15885, 65533, 3801, 65535, 6038, 0, 32768, 7616, 32768, 32768, 65534]

Every number is a set of 2 bytes.

The first number is position 40070 (I know, we've started at 40069, but the readout starts at 40070, i don't know why)

Step 1 is skipping to the reading i want:
data.skip_bytes(12)
Brings us 6 numbers further to position 40076 (65534), this is know as the scalefactor of AC current. So we read it out:
scalefactor = 10**data.decode_16bit_int()
The result is: scalefactor = 0.01
The data decode is 16bit int. And results in a -2.

When we do a data.decode my position automaticly go's to the next position. So my position at this point is 40077.

We need to go back to the reading of the AC current. So.
data.skip_bytes(-10)
Brings us 5 numbers back to position 40072 (2497)
# Register 40072
datapoint['fields']['AC Total Current'] = trunc_float(data.decode_16bit_uint() * scalefactor)
We decode register 40072 and multiply it with the scalefactor. Resulting in 24,97
The result is stored as datapoint in a string.

The proces repeats for every reading.

This proces is needed because my meter has different scalefactors as your meter and this setup works for every solaredge meter. In the wattnode part we've took a shortcut. because you're the only one with a wattnode meter. I've simply put al the scalefactors directly in the readout.

Example:
First we decode the AC Current C. And multiply it with the scalefactor 10**-1
datapoint['fields']['M1 AC Current C'] = trunc_float(data.decode_16bit_int() * 10**-1)
The a skip to bytes, because this is the scalefactor. And i don't need it.
data.skip_bytes(2)
Then i continue with the next datapoint
datapoint['fields']['M1 AC Voltage L N'] = trunc_float(data.decode_16bit_int() * 10**-2)

We could make the solaredge part the same as the wattnode part.

Some points are 32 bit. They use 4 bytes, and 2 numbers. To create a bigger number.

This proces is not really python. It's more ModBus.

Hopefully my story makes any sense.

Regards
