Incorrect start/stop size

[dominikamann]

Hi all,

I try since hours to get the connection running. Do you have any ideas?

Thank you!!

# The device to read from...
# Use: /dev/ttyS0 if you have a serial device,
#      /dev/ttyUSB0 if a USB<>Serial,
#      /dev/hidraw0 if you're connecting via the USB port on the inverter.

device=/dev/hidraw0

# How many times per hour is the program going to run...
# This is used to calculate the PV & Load Watt Hours between runs...
# If unsure, leave as default - it will run every minute...

# (120 = every 30 seconds)...
run_interval=120

# This allows you to modify the amperage in case the inverter is giving an incorrect
# reading compared to measurement tools.  Normally this will remain '1'
amperage_factor=1.0

# This allos you to modify the wattage in case the inverter is giving an incorrect
# reading compared to measurement tools.  Normally this will remain '1'
watt_factor=1.01

I have the Axpert Max 8kw and these are my settings

109 40 5 112

I found that if you put the numbers high like 130 it will say that it's too high and expected 112 for instance so drop it to that and slowly lower, I was lucky with the 112 but the 109 took a few guesses because I did everything except and 40 was a pure guess :)

Oh and I would really like your inverter :) the 900 pv open circuit would be good for me

[gysief]

I has have an Axpert inverter. have the same problem I am updating the config/inverter.conf but the setting is not pulling through. Am I in the wrong location. I wanna try your setting. I have even try deleting the docker images.

Kind Regards G

I have an Axpert 3kW inverter (24V) and these settings worked for me:

qpiri=99
qpiws=40

[dominikamann]

Thanks for your responses. I was not able to find a solution. But it works with MPP-SOLAR and Protocol PI17 (https://github.com/jblance/mpp-solar/blob/master/mppsolar/protocols/pi17.py). May it is possible to add it to docker-voltronic-homeassistant?

[dominikamann]

Workarround until it may works with this integration.
