Obtain individual inverter information in a 3 phase installation about mpp-solar HOT 14 CLOSED

There are different protocols for different versions of inverter.
The QP2GS command is in the LV5048 command set (add -M L:5048 to the command to use it)
Better is to check the protocol with the QPI command.

Does QPGS1 command give results?
Note both QPGS and QP2GS require a number at the end (its the inverter number and normally counts from 0)

from mpp-solar.

Hi John, thank you for your quick answer.

The answer to the QPI command is the following:
protocol_id PI30

I obtain also an answer to the QPGS1 command.

Thanks a lot for you help.

Good news, in case you haven't already realized it QPGS2 will likely give you the 3rd phase inverter details

from mpp-solar.

Yes, you are right. With QPGS"x" command I am able to obtain the information of each individual inverter using the appropiate value of "x":
0 - For inverter 1
1- For inverter 2
2 - For inverter 3

However I am afraid that I have not configured in the right way the mpp-solar service to get the statistics of each inverter. The "mpp-solar.conf" file that I am using is the following one:
[SETUP]
pause=5
mqtt_broker=127.0.0.1

[Aggregated_All_Inverter_Info]
model=standard
port=/dev/hidraw0
baud=2400
command=QPIGS
tag=Aggregated
format=influx2

[Inverter1]
model=standard
port=/dev/hidraw0
baud=2400
command=QPIGS0
tag=Inverter1
format=influx2

[Inverter2]
model=standard
port=/dev/hidraw0
baud=2400
command=QPIGS1
tag=Inverter2
format=influx2

[Inverter3]
model=standard
port=/dev/hidraw0
baud=2400
command=QPIGS2
tag=Inverter3
format=influx2

In Graphana I am able to see the different tags "Inverter" but with no data.

Can you help me to identify what I am doing wrong?

Thank you very much.

Well first off the inverter1 - 3 commands are incorrect (you have QPIGS1 instead of QPGS1)
Other problems are difficult to see from just the conf file

• what is the service status results?
• try subscribing to the mqtt broker in a command window and see what is getting published
• what is telegraf service status
• what is in the influxdb

from mpp-solar.

Again you are right. The commands were wrong. Sorry for that.

I have review the points you mention in your previous answer. Here are the results.

The mpp-solar service is ok and working without errors.
I have subscribed to the mqtt broker using the following command
sudo mosquitto_sub -h localhost -v -t "mpp-solar"
and I have only seen message from the "Aggregated" command but not for the other ones (Inverter1, Inverter2 and Inverter3). I suppose that this is the reason because I didn't see any data in Graphana related to Inveter commands but I don't know how to fix it.

The telegraph service is also running and there is only a warning message "Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable."

The influx db is also working.

I hope I provide you enough information to help me.

Thanks again for your help.

Please provide the logs from the mpp-solar service

from mpp-solar.

Also restart the service and supply the startup logs

from mpp-solar.

I attached the log file.
mppsolar.log

I have also restarted de service:
fran@Valor:~ $ systemctl --user restart mpp-solar
fran@Valor:~ $ systemctl --user status mpp-solar
● mpp-solar.service - MPP Solar Service

I attach also the logs after restarting the process.
mppsolar_restarted.log

Thanks for your help.

Can you re post the configuration file
Does the mppsolar command on the command line work without sudo?

from mpp-solar.

Hi again. Here is the configuration file:

mpp-solar.conf.txt

The mppsolar command does not work without sudo in the command line.

Don't heasitate to ask me any other information.

Have a nice day.

Config still has the wrong commands in it
You need to either get the mppsolar command working without sudo (as in the docs somewhere) or to move the service to be a system service (not in the docs but covered in the original source which is linked in the docs)

(Sorry on my phone so can't easily be more specifc)

from mpp-solar.

Hi John, the problem is already solved. I updated the commands in the config file. In addition I have solved also the problem with the execution with sudo. Now all is working.

Thank you so much for your help.

Great news
Glad it works for you
