[RE-wrenches] 1/2 wave loads

[Howie Michaelson]

I installed a couple of EG4 18k inverters off grid this past spring, made
by LuxPower as is the Envy.  They look very similar both visually and
programmatically. Withone install, there has been a steady problem of the
inverter shutting off when the client uses a hair dryer. The other client
has not reported any issues with the inverter cycling off.  Tech Support's
solution to this issue which they referred to as stemming from half-wave
loads, was to run another load simultaneously which was supposed to help
prevent the nuisance momentary shutdown, but according to the client, it
hasn't helped. After bugging tech support for several months about this
issue, they finally told me that there was a hardware design flaw that they
were working on resolving and when they had it fixed, they would send out a
replacement inverter. I asked if they would be replacing both inverters,
but they said since one hasn't reported any issues, they would not be
replacing that one. That was at least 2 months ago, and I have not heard
anything since.
