when using the built-in usb-b port, there can be some stability issues, due to power issues.
this appears to be a problem between various brands of inverters.

to solve this, a usb-usb isolator can be put inbetween.
ADUM3160 chipset / isolator, a bit pricey; prices vary, can look around for a better listing.

Were you referencing the EG4 18kPV here? Asking because after having this running for a while it seems as if I'm running into power issues on the USB-B port powering the Pi Zero.

Curious if you experienced this problem or not.

i experienced this with all of my hybrid inverters. i dont have an EG4, but i think the problem persists in most hybrid inverters since the designs are all so similar. think its releated to the grounding for the usb ports, and it can take a few months before it shows.

That's exactly what happened then! It took a few months for it to show up hahahaha. All good, thanks for responding!
