![]() You no longer have to check the state of charge with a hygrometer, or top the batteries up with distilled water. Lead acid battery technology has come a long way since 1859, the year it was invented. There are a lot of different battery technologies, but lead acid batteries, which consist of plates of lead dioxide and spongy lead, immersed in a sulphuric acid solution contained in a durable housing, are most appropriate for use with inverters and mobile power solutions. The main safety agencies, CSA, UL, and ETL, have all approved inverters with this half-voltage on the neutral scheme, and the manuals contain warnings not to AC hardwire any of these inverters.Ī battery is a device that stores energy while it is being charged and releases energy while it is being discharged. As a result the 60V neutral is not accessible to the user, and any shock hazard presented is mitigated by lack of access. This is because there are many receptacles that are wired backwards or 2-prong plugs that are not polarized. The impact of that is minimal, since wiring and equipment connected to the neutral side of the circuit are required by safety standards to be treated as if they were at 120Vac. 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 Monitor is equipped with an internal programmable alarm relay, to run a generator when needed or to turn off devices when the battery voltage exceeds programmable boundaries.The remote on/off switch for Prowatt and Portawattz products is part number 808-9000. A second battery input is also provided to monitor voltage on a second battery. Using a clear backlit LCD Display and an intuitive user interface, all parameters can be recalled with just a button press. The Xantrex LinkPRO Battery Monitor selectively displays voltage, charge and discharge current, consumed amp hours, remaining battery capacity and the time remaining of your battery bank.
