[RE-wrenches] Nuetral - Ground Bond. Was- Outback wave form

[All Solar, Inc.]

I found out that the appliance will work fine from an extension cord with a portable generator.
The appliance will not even work however when the backup gen is running and transfering through the inverters.
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 the same (stacked pair)

        Wrenches,

        While the addition of a capacitor may resolve issues associated with various
        inverter/appliance/motor combinations, please make sure the capacitor(s) get
        switched OUT of the circuit (disconnected) when the load itself is disconnected.

        Failure to do so could under some circumstances cause the inverter control-loop
        circuitry to go unstable, leading to unpredictable inverter operation, and possible
        damage/failure in the power system.  Disconnecting the capacitor with the load
        alleviate this possibility.


        Regards to all...

          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





          By adding a 50uF run capacitor inline, it somewhat tames the current phase and the sine wave so the Magnum can operate the washer.

          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?
