Axpert MKS IV Hybrid stops responding every few weeks

Closed this issue 2 months ago · 3 comments

Thanks for the great project. I have a rebranded Axpert MKS IV Twin Hybrid 6kW inverter that I use with mpp_solar and it works great with PI18 over USB (/dev/hidraw0). However, the inverter just stops responding every few weeks and I have to restart it. I remember someone else reported the same issue but I can’t find it. Any ideas for a fix?

I havent investigated this (that I can recall)
Is the problem with the inverter or does mppsolar fail?
Any debug / logs from the time of failure?
Have you tried other resolution approaches?

It’s an issue with the inverter. It just stops responding. Actually the hidraw0 device also disappears. Not sure what to try. Was wondering if you had any ideas.
