The grounding is correct, in that loads plugged in will have their chassis held at the same ground potential as the chassis of the inverter, but the neutral has approximately 60V on it instead of the usual 0V. Regarding the voltage that the you are measuring, the ground does not float halfway, rather the neutral is not at 0 volts. The US standard for inverters of this sort, UL458, does not have a requirement for a bonded neutral on the output of inverters. The fact that the inverter is not a permanent installation means the US NEC (United States National Electrical Code) doesn’t apply, and the NEC is the main place where the requirement resides for single-phase 120Vac or 240Vac systems to have neutral bonded to earth. Your inverter is designed to have loads plugged directly into it and not be permanently connected to an AC distribution system. This FAQ applies to Xpower, PROwatt, Portawattz, Jazz and Xantrex inverters, including the inverters integral to Powerpacks. Instead, the safety ground appears to float about halfway between the neutral and hot pin voltage. There is 124 vac between the hot and neutral pins but the safety ground is not at 0 volts with respect to the neutral pin. However, the output voltage doesn’t seem right. I’ve installed the modified sine wave inverter and it’s working okay.

Do not use the electrical information at the above-noted FAQ for XPower Plus inverters. It is also available through Xantrex E-store. For the XPower 1200 Plus and XPower 1750 Plus inverters, the correct remote switch part number is 808-9500. NOTE: This switch does not work with XPower Plus inverters. You can find more information on the electrical requirements of the switch at our support FAQ under Prowatt products entitled Prowatt 1000/1750/3000 Remote Control.
The Prowatt and Portawattz models mentioned above can be controlled remotely by an external dry-contact switch. The remote switch can be purchased through Xantrex E-store (under Accessories) if your local Xantrex dealer doesn’t carry it. It includes 20 feet (6 meters) of cable and works with the following products:Īll Prowatt inverters over 800 watts, whether 12 or 24VDC and whether domestic or international. The remote on/off switch for Prowatt and Portawattz products is part number 808-9000.
