Thanks for the reply @Coulomb. I had zero success getting the command to work over USB last night, even using the Python code linked directly, so eventually I just switched over to using the RS232 port with a serial to USB adapter instead of the USB port and everything is working perfectly without any other modifications. I would never have thought to try that so thanks for the heads up.

Hi there, I have an Axpert Max 7.2 which is running the following firmware versions as read from the commands below. QVFW: VERFW:00045.07 QVFW3: VERFW:00012.13 Shouldn't really matter but I am executing the commands over USB using some home-rolled code heavily inspired by the code found here. I am attempting to read data for the second PV string using the QPIGS2 command but I am running into an issue where the inverter is not returning a response. I'm able to run all of the other queries I've tried to run thus far (QPIRI, QMOD, QPIGS, QLED) Is there something that I need to do differently to read data from the QPIGS2 command or is this potentially an issue that can be resolved with a firmware update, and if so, could someone please point me in the right direction to find the firmware versions? Some guidance would be greatly appreciated. Thanks in advance...
