[RE-wrenches] midnite new inverter

Fri Apr 12 06:09:28 PDT 2024

Bill,
   Now that you mention it I did not have an SPD near the inverter,  I have
one  on 1 of 2 TOP Racks, other rack with old Delta... My inverter lives on
my workbench to allow swapping other inverters in for load testing using my
whole house with everything connected to ancient wiring which did not
include an SPD.  I put them on all my customers' systems and have had no
issues on most of them and have never had to replace one. .  I have removed
lots of those grey cans but have not taken care of my own system !!!  The
Fortress eflex was not fully protected either.  That strike would have been
the perfect test of the SPD's if I had them all installed. I  had a perfect
real world test of
Outbacks ACA with surge protection  on two GVFX inverters that had annual
lightning failure until I installed their surge protectors.  There have
been no more failures since (at least 10 years)  The lightning was so
severe at that  location that the power company was constantly having
issues on that power line.
