Re: [RE-wrenches] Fisher Paykal on a MAGNASINE

According to a document I received from an F-P technician, here is what it takes to run their washers on an inverter: I passed this document on to the list late last year, so check your attachments folder for
Using 120V Alternate Energy Generation.doc

Are There Existing Customers who are Successfully  Running a Smart Drive Autowasher From An Inverter Supply?
 
There are many installations where Smart Drive Autowashers are successfully operating on an inverter supply.  In our experience if the following technical criteria are met  by an inverter then operation and reliability should not be an issue:
 
RMS Voltage:  120V +/- 10%  (up to -20% may still work provided the pump outlet hose is not too high i.e. pumping a high head of water)
Frequency:       60 Hz +/- 5%
Peak Voltage:  200V peak - This is the major point!!!
Older style inverters can have an rms voltage inside specification but do so by having short duration high voltage pulses.  The Smart Drive treats this high voltage pulse as a voltage transient and clamps the voltage above 200V.  The electronics are well rated to absorb this clamp energy on a transient basis but not 120 times a second  (60Hz) continuously.  If this continuous clamping occurs then it may lead to premature failure of the Smart Drive electronics or the Inverter electronics.
Power Rating:  2kVA (2,000VA) minimum.
While the Smart Drive only consumes about 650W of power maximum, the VA rating can exceed 1kVA.  Successful installations have a rating of 2kVA min.

According to others on this list, the sine wave Magnum won’t run one, so I would be very cautious.

Has anyone run a Fisher-Paykal washer on the Magna sine modified sine wave 1200 watt inverter? Good to do or not?
 
Thanks
