<div class="moz-cite-prefix">The Outback is not a perfect Sinewave.
It still has tiny steps in the wave, and when electronics have a
problem, its usually with the wave form as it crosses zero voltage
. Instead of being instantaneous, it has a few milliseconds of
time the wave is at the zero crossing, which can drive some
electronics nuts. I don't understand the issue beyond that, but
apparently the electronics use the zero crossing for timers and
synchronizing, and they're looking for an instant "click", not a
smear. <br>
Do the heat pumps work with the generator? Even though generators
can have more harmonic distortion, they do usually have a clean
zero crossing.<br>
If this is the case, I'm afraid I don't have a cure. We used to
use capacitors, but Dan from Exeltech just poo pooed that fix in
another recent thread, so I don't have any other tricks up my
sleeve.<br>

<div>Anyone else had issues with Mitsubishi Mini Split heat
pumps fighting with Outback VFX off grid inverters? Everything
is brand new. Outback VFX7248, three separate heat pumps. The
heat pumps shut down reporting multiple / confusing input
commands. The heat pump guys want to blame the power system.
I'm thinking bad Sushi. Thanks db<br>
