Signature Solar is sending me 2 ground screws for my 6500s. The tech states that installing the screws should fix the led flickering issue. I have my grid mains panel NG bonded and the N and G ran to inverters via terminal blocks in the PDP. I've read a lot on the NG bond issue and seems like to me creating 2 NG bonds isn't ideal. Am I overlooking something?
Before I proceed question, SS and ground screw for flickering

The screws allow the unit to provide the N/G bond when they disconnect from the AC input.

I run a pair of LV6548's with one inverter N-G bonding screw installed.
