Reading from Sunstonepower 10KW 48V 3-Phasen Hybrid Inverter

[antaril]

Hi there,

iam trying to read from my inverter via usb, but when i do : "sudo /home/pi/.local/bin/mpp-solar -p /dev/hidraw0 -c QPIGS"

i got this back:
Command: QPIGS - General Status Parameters inquiry

Parameter Value Unit
ac_input_voltage 0.0 V {'icon': 'mdi:lightning'}

is this a problem of me, or is the inverter not compatible? Can i read from rs232?
It would be great if someone can help me!

You don't give allot of info so lets start with some basics.

What returns from the following commands?
sudo /home/pi/.local/bin/mpp-solar -p /dev/hidraw0 -c QPI
sudo /home/pi/.local/bin/mpp-solar -p /dev/hidraw0 -c QMN
Try maybe:
sudo /home/pi/.local/bin/mpp-solar -p /dev/hidraw0 -c QPGS1
