Yeah, or have unshrouded probes cross accidentally.You have a point, some of those terminals are extremely close to the metalwork of the inverter and if you don't have fully shrouded probes it would be very easy to cause a short.
This is a good idea and would save me having to press the shutter button, but getting an angle where it was clear the probes were touching the PV terminals took some moving around because there's a few wires and what I think is a toroid on each terminal set, which I definitely WILL NOT be messing with at 450V DC.Next time you could set your phone up and record a video then take a screenshot with the relevant information.
It's to bad these inverters don't just work.
