fentonups - Driver for Fenton Technologies (Megatec protocol) UPS equipment
This man page only documents the hardware-specific features of the fentonups driver. For information about the core driver, see nutupsdrv(8).
fentonups primarily supports Fenton Technologies models such as the PowerPal, PowerPure and PowerOn lines. Due to the common heritage of UPS equipment, it generally supports other hardware that also uses the Megatec protocol. At the time of this writing, the PowerGuard PG-600 and PowerCom SMK-800A are recognized and supported. Other Megatec units should also work, but they will generate a warning since their battery information is not known.
This driver does not support any extra settings in the ups.conf(5).
The battery percentage is derived from the voltage data that the UPS returns, since the UPS doesn't return that value directly. On some hardware, the charge will remain at 100% for a long time and then drops quickly shortly before the battery runs out. You can confirm from the BATTVOLT readings that this is a problem with the UPS and not this driver. Similarly, the float from the charger in some models forces the battery charge percentage back up to 100% immedately after the UPS goes back on-line, so you can't tell when it is really recharged. Dead/broken batteries can't be reported reliably. If your UPS kills the load instantly or within seconds of starting the inverter, your batteries probably need to be replaced. Recently, a pair of 3.5 hour outages here (thanks CPS!) finally killed my batteries. You may have to run a manual test from the front panel before the "replace battery" LED will light.
