[RE-wrenches] Sol-Ark 15k solar panel frame grounding

[Mac Lewis]

Hi Jason,

You should be able to land your PV EGC in the inverter ground bar.  You
could do a quick resistance check to verify the +, - PV

Is there a bond somewhere (upstream service panel or in the Sol-Ark itself)
between ground and neutral?  If not, this can cause this fault.
