10 This man page only documents the hardware-specific features of the
11 bestups driver. For information about the core driver, see
12 nutupsdrv(8).
13
15 bestups was designed to monitor Best Power UPS hardware like the
16 Fortress, Fortress Telecom, Axxium Rackmount and Patriot Pro. It also
17 recognizes and supports SOLA units such as the 325, 520 and 620. In
18 addition, the Best 610 is supported using the ‘ID’ option.
19 Other UPS hardware using the Phoenixtec protocol should also work, but
21 they will generate a warning since their battery information is not
22 known.
23 This driver does not support some older Best/SOLA units.
25
27 This driver supports the following optional settings in the
28 ups.conf(5):
29 nombattvolt=num
31 Override the battery float voltage which is normally determined by
32 asking the hardware. This is useful if your UPS constantly reports
33 battery.charge values just below 100% even when it’s completely
34 charged.
35 If you have this problem, set this to whatever battery.voltage
37 reports when the UPS is known to be completely charged with a good
38 battery.
39 The author’s Best Fortress 750 uses nombattvolt=27.4.
41 battvoltmult=num
43 Multiply the reported battery voltage by this number. Some devices
44 report only a fraction of the total battery voltage.
45 For example, the SOLA 610 700VA UPS (with a 24V battery) reports
47 the single cell voltage (about 2.27V when fully charged). In this
48 particular case you can set battvoltmult = 12 in ups.conf(8) to fix
49 this.
50 ID=string
52 Set the Identification response string. This should only be used
53 with hardware that supports the Phoenixtec protocol status inquiry
54 commands, but not the "ID" command, such as the Best/SOLA 610.
55 Format of the ID string is: AAA,BBBB,CCC,DDD,EE.E,FF.F
56 AAA is the three-character identification for the UPS model.
58 BBBB is the output power in VA (volt amperes). B is an integer
60 number ranging from 0 to 9.
61 CCC is the Nominal Input Voltage. C is an integer number ranging
63 from 0 to 9. The unit is Volts AC.
64 DDD is the Nominal Output Voltage. D is an integer number ranging
66 from 0 to 9. The unit is Volts AC.
67 EE.E is the Battery Voltage that will cause the UPS to shut itself
69 off. E is an integer number ranging from 0 to 9. Then unit is Volts
70 DC and a decimal point is present.
71 FF.F or FFF.F is the Battery Voltage at full charge. F is an
73 integer number ranging from 0 to 9. Then unit is Volts DC.
74 Typically, for 700VA, 1KVA and 1.5KVA units, the format is FF.F.
75 For 2KVA and 3KVA units, the format is FFF.F.
76 Example: a Best 610 1.5KVA unit would use the string
78 "610,1500,120,120,10.0,48.0".

81 The battery charge percentage value (in battery.charge) is derived from
82 the voltage data that the UPS returns, since the UPS doesn’t return
83 that value directly. On some hardware, the charge will remain at 100%
84 for a long time and then drops quickly shortly before the battery runs
85 out. You can confirm from the battery.voltage readings that this is a
86 problem with the UPS and not this driver.
87 Similarly, the float from the charger in some models forces the battery
89 charge percentage back up to 100% immedately after the UPS goes back
90 on-line, so you can’t tell when it is really recharged.
91 Finally, some models give one value for the battery’s nominal voltage
93 and yet actually have a nominal voltage slightly below that. This leads
94 to things such as the perpetual 98.7% charge on the author’s Fortress
95 750, even when it’s been charging for weeks. You can use nombattvolt=
96 in ups.conf(8) to fix this.
