When you hook up your 40 amp charger while running the generator, do you disconnect the house batteries first to prevent back feeding into the converter? My understanding is that on the newer converters, back feeding can cause them to over heat and possibly cause a fire. You would then have a pile of ashes where your PC was sitting.
Marilyn If you did not have a battery problem with your PW then you should not have a problem with your PC. The PC has newer technology so it will be better than the PW. Save your money or put it into the gas tank and enjoy your PC.As the Australian say "No worries, mate".
