I got a referbed board set from OB with pre stripped AC terminal screws.. I was not in the position to postpone the rebuild so I did something similar.. And more recently, discovered that some GT inverters only get like 6 in lbs.. Let's see Uncle Larry 'Just feel' that one out..

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.JerryOn Wed, Jan 4, 2017 at 7:15 AM, Benn Kilburn <[email protected]> wrote: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.
