[RE-wrenches] Panasonic PV modules, missing you

[Ray Walters]

Dellta LA  lightning arrestors would not prevent the diode damage you=20
mentioned.  I think many others on the list will confirm that Delta LAs=20
are not effective at preventing equipment damage, and probably only=20
useful in preventing complete wire melt down.  Midnite found the Delta=20
didn't start clamping till well over 2000 volts. It might be=20
coincidence, but we have not a single case of lightning damage since we=20
switched to the Midnite SPD protection.  The Delta isn't even UL listed=20
anymore.
