[RE-wrenches] Stripped screws... Fronius IG Plus PV terminals

[Benn Kilburn]

Happy New Year Wrenches!

Wondering if anyone has had issues with stripping screws for PV (or other...AC/gr) set-screw terminals that are integral to an inverter?  In this case specifically, a Fronius IG Plus 11.4-3. 

A torque screwdrivers was not used at this point as it happened as the wires were initially being terminated. The ones that did strip, did so with noticeably less (hand torque) pressure than was applied to other terminals in same inverters that snugged up just fine.
