NAME

6       bestups - Driver for Best Power / SOLA (Phoenixtec protocol) UPS
7       equipment
8

NOTE

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

SUPPORTED HARDWARE

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
20       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
24       This driver does not support some older Best/SOLA units.
25

EXTRA ARGUMENTS

27       This driver supports the following optional settings in the
28       ups.conf(5):
29
30       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
36           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
40           The author’s Best Fortress 750 uses nombattvolt=27.4.
41
42       battvoltmult=num
43           Multiply the reported battery voltage by this number. Some devices
44           report only a fraction of the total battery voltage.
45
46           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
51       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
57           AAA is the three-character identification for the UPS model.
58
59           BBBB is the output power in VA (volt amperes). B is an integer
60           number ranging from 0 to 9.
61
62           CCC is the Nominal Input Voltage. C is an integer number ranging
63           from 0 to 9. The unit is Volts AC.
64
65           DDD is the Nominal Output Voltage. D is an integer number ranging
66           from 0 to 9. The unit is Volts AC.
67
68           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
72           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
77           Example: a Best 610 1.5KVA unit would use the string
78           "610,1500,120,120,10.0,48.0".
79

BUGS

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
88       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
92       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.
