NAME

       bestups - Driver for Best Power / SOLA (Phoenixtec protocol) UPS equipment

NOTE

       This man page only documents the hardware-specific features of the bestups driver. For information about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

       bestups was designed to monitor Best Power UPS hardware like the Fortress, Fortress Telecom, Axxium Rackmount and Patriot Pro. It also
       recognizes and supports SOLA units such as the 325, 520 and 620. In addition, the Best 610 is supported using the 'ID' option.

       Other UPS hardware using the Phoenixtec protocol should also work, but they will generate a warning since their battery information is not
       known.

       This driver does not support some older Best/SOLA units.

EXTRA ARGUMENTS

       This driver supports the following optional settings in the ups.conf(5):

       nombattvolt=num
	   Override the battery float voltage which is normally determined by asking the hardware. This is useful if your UPS constantly reports
	   battery.charge values just below 100% even when it's completely charged.

	   If you have this problem, set this to whatever battery.voltage reports when the UPS is known to be completely charged with a good
	   battery.

	   The author's Best Fortress 750 uses nombattvolt=27.4.

       battvoltmult=num
	   Multiply the reported battery voltage by this number. Some devices report only a fraction of the total battery voltage.

	   For example, the SOLA 610 700VA UPS (with a 24V battery) reports the single cell voltage (about 2.27V when fully charged). In this
	   particular case you can set battvoltmult = 12 in ups.conf(8) to fix this.

       ID=string
	   Set the Identification response string. This should only be used with hardware that supports the Phoenixtec protocol status inquiry
	   commands, but not the "ID" command, such as the Best/SOLA 610. Format of the ID string is: AAA,BBBB,CCC,DDD,EE.E,FF.F

	   AAA is the three-character identification for the UPS model.

	   BBBB is the output power in VA (volt amperes). B is an integer number ranging from 0 to 9.

	   CCC is the Nominal Input Voltage. C is an integer number ranging from 0 to 9. The unit is Volts AC.

	   DDD is the Nominal Output Voltage. D is an integer number ranging from 0 to 9. The unit is Volts AC.

	   EE.E is the Battery Voltage that will cause the UPS to shut itself off. E is an integer number ranging from 0 to 9. Then unit is Volts
	   DC and a decimal point is present.

	   FF.F or FFF.F is the Battery Voltage at full charge. F is an integer number ranging from 0 to 9. Then unit is Volts DC. Typically, for
	   700VA, 1KVA and 1.5KVA units, the format is FF.F. For 2KVA and 3KVA units, the format is FFF.F.

	   Example: a Best 610 1.5KVA unit would use the string "610,1500,120,120,10.0,48.0".

BUGS

       The battery charge percentage value (in battery.charge) 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 battery.voltage 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.

       Finally, some models give one value for the battery's nominal voltage and yet actually have a nominal voltage slightly below that. This
       leads to things such as the perpetual 98.7% charge on the author's Fortress 750, even when it's been charging for weeks. You can use
       nombattvolt= in ups.conf(8) to fix this.
