Westinghouse iGen11000DFc

“Final reply from Westinghouse Support: > Thank you for the detailed explanation and for the thorough testing you have already completed. I truly appreciate the level of detail you provided, and I understand why you are trying to pinpoint the exact source of the parasitic draw. > > Regarding your question about the always wired regulated rectifier circuit: on the iGen11000DFc, the rectifier regulator and battery management related circuitry are integrated into the internal electrical system and inverter/control module assembly. These components are not user serviceable and are not designed to be relocated from the always hot side to the switched side. Unfortunately, we do not have access to, nor are we able to provide, internal engineering schematics beyond what is shown in the owner’s manual wiring diagram on page 32. > > The measured 2.1 mA standby draw you documented is within normal specification for this model and is consistent with what we expect from the control electronics and battery management system, even when the rocker switch is off. While I understand your concern based on the battery capacity math, there is no approved modification or field adjustment to isolate or re route that circuit. > > At this time, the recommended solution remains periodic charging or running the unit, or maintaining the battery with an external Li Ion compatible maintainer if utility power is not available at the storage location. Any modification to the wiring or control circuitry would not be recommended and could affect safety, operation, or warranty coverage. > > I know this may not be the answer you were hoping for, but I appreciate your patience and the detailed troubleshooting you have already done. Please feel free to reach out if you have any other questions or need further assistance.”
