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

[Jerry Shafer]

Wrenches
Every once in awhile we have had issues with cross tread or striped threads
on screws, this happens when the screws are backed out to far and dont line
up correctly and this causes the problems, I have had this with SMA,
Fronius and Outback along with combiners, I get called to fix this when
someone does this, what I have had to do is to take the plastic covers off
and swap screws and clamps to get them where they need to be. I do not
recommend this but when in Rome. FyI dont let anyone use powered screw
drivers as this can cause some of these issues.
