QPIGS and Invalid response CRC
I have a "Powmr POW-HVM 6KW" inverter. I connected it via rs232 and most of the commands from the PI30 protocol work fine for me, but for the QPIGS command I get a message about an incorrect crc in the response. Could someone advise what I should change to make it work?

can you upgrade to the latest version - if you are using pip then uninstall mpp-solar and install mppsolar (note lack of dash)
Hi, Suddenly I am dealing with the same issue, all commands go fine, but the needed QPIGS fails. I am running 0.12.5 on Rpi.

I upgraded to the latest version. unfortunately, when sending the QPIGS command, I still get an incorrect CRC :( On various forums I read that some inverters return more data or inverter ends line with a LF instead of a CR. can you help to resolve my problem? what can i do to diagnose what the problem is?

Interesting, this "invalid CRC response" happens on my pi on USB0, but works on USB1 Fund it by coincidence. I had another device plugged all the time, so usb-serial cable was on USB1. Then i cleaned my setup, only solar on pi on USB0 - it won't work.... Later i reverted it to USB1 by plugging something to usb before usb-serial and it works again on USB1 I don't know the reason for that :/
