Outback may be right on, and it's worth checking.<br>
<br>
Most portable gennies internally bond neutral to chassis, because
they expect that no typical homeowner will ground the chassis.
(Inverter-generators are a noteworthy exception to this.) Most
inverter systems also have a neutral-ground bond, if done to Code.
Whe plugged into the gennie, there's thus an inherent ground loop.
Try disconnecting the grounding conductor on the extension cord.<br>

<div>I found out that the appliance will work fine from an
extension cord with a portable generator.</div>
<div>The appliance will not even work however when the backup gen
is running and transfering through the inverters.</div>
<div>Outback T.S. suggested to check the Neutral to ground bond so
that is the next step. Also tried to set the Power Save levels

While the addition of a capacitor may resolve issues
associated with various<br>
inverter/appliance/motor combinations, please make sure
the capacitor(s) get<br>
switched OUT of the circuit (disconnected) when the load
itself is disconnected.<br>
<br>
Failure to do so could under some circumstances cause
the inverter control-loop<br>
circuitry to go unstable, leading to unpredictable
inverter operation, and possible<br>
damage/failure in the power system. Disconnecting the
capacitor with the load<br>
alleviate this possibility.<br>

<div class="plainMail">We experience issues like this
from time to time. PF seems to be the culprit. Have
you measured it or looked at the waveform yet? How
an inverter deals with PF seems to vary broadly. For
example, the Splendide XC2100 washer/dryer will not
work on a Magnum Energy and a few other sine wave
inverters. However, it will run on a low cost
GoPower or Samlex sine wave inverter. Below is a
scope trace of voltage/current of the Magnum
inverter & Splendide washer. Upper trace is
voltage<br>
<br>
<br>
</div>
<div class="plainMail"><br>
<br>
By adding a 50uF run capacitor inline, it somewhat
tames the current phase and the sine wave so the
Magnum can operate the washer. <br>

Have a client with a new coffee maker that will not
run from their new dual outback setup. Has anyone
heard of this lately. We have had no problems with
appliances and sine wave inverters. What to look
for?<br>
