>From my cryptic notes the Array Solutions box used:

10000 pF / 1KV capacitor
82V Varistor 6.5KA

Cost ~$1.00 for the capacitor and varistor from Digikey or Mouser.

John,
>From the photos, each lead has an MOV and capacitor in parallel shunted to
ground.  The Array Solutions boxes are really nice and convenient, but in a
few hours I could fabricate that with a grounding buss bar,  NEMA box and
some stainless hardware.

What values would you recommend for the MOV and capacitor?

wondering if anyone has any input as to which ones work the best? Source and
