Fortress Telecom, and Patriot Pro. It also recognizes and supports SOLA
12
units such as the 520 and 620.

Fortress Telecom, Axxium Rackmount and Patriot Pro. It also recognizes
12
and supports SOLA units such as the 325, 520 and 620. In addition, the
13
Best 610 is supported using the `ID' option.

15
Other UPS hardware using the Phoenixtec protocol should also work, but
15
16
they will generate a warning since their battery information is not known.
17
This driver does not support some older Best/SOLA units. Try the bestfort
18
driver if this one does not detect your UPS.

.SH EXTRA ARGUMENTS
22
This driver does not support any extra settings in the
22
This driver supports the following optional settings in the
25
.IP "nombattvolt=\fInum\fR"
27
Override the nominal battery voltage which is normally determined by
28
asking the hardware. This is useful if your UPS constantly reports
29
battery.charge values just below 100% even when it's completely charged.
31
If you have this problem, set this to whatever battery.voltage reports
32
when the UPS is known to be completely charged with a good battery.
34
The author's Best Fortress 750 uses nombattvolt=27.4.
38
Set the Identification response string. This should only be used
39
with hardware that supports the Phoenixtec protocol status inquiry
40
commands, but not the "ID" command, such as the Best/SOLA 610. Format
41
of the ID string is: AAA,BBBB,CCC,DDD,EE.E,FF.F
43
AAA is the three-character identification for the UPS model.
45
BBBB is the output power in VA (volt amperes). B is an integer number
48
CCC is the Nominal Input Voltage. C is an integer number ranging from 0
49
to 9. The unit is Volts AC.
51
DDD is the Nominal Output Voltage. D is an integer number ranging from 0
52
to 9. The unit is Volts AC.
54
EE.E is the Battery Voltage that will cause the UPS to shut itself off.
55
E is an integer number ranging from 0 to 9. Then unit is Volts DC and a
56
decimal point is present.
58
FF.F or FFF.F is the Battery Voltage at full charge. F is an integer
59
number ranging from 0 to 9. Then unit is Volts DC. Typically, for 700VA,
60
1KVA and 1.5KVA units, the format is FF.F. For 2KVA and 3KVA units, the
63
Example: a Best 610 1.5KVA unit would use the string
64
"610,1500,120,120,10.0,48.0".
27
The battery percentage is derived from the voltage data that the UPS
28
returns, since the UPS doesn't return that value directly. On some
29
hardware, the charge will remain at 100% for a long time and then drops
30
quickly shortly before the battery runs out. You can confirm from the
31
BATTVOLT readings that this is a problem with the UPS and not this driver.
68
The battery charge percentage value (in battery.charge) is derived from
69
the voltage data that the UPS returns, since the UPS doesn't return that
70
value directly. On some hardware, the charge will remain at 100% for a
71
long time and then drops quickly shortly before the battery runs out.
72
You can confirm from the battery.voltage readings that this is a problem
73
with the UPS and not this driver.
33
75
Similarly, the float from the charger in some models forces the battery
34
76
charge percentage back up to 100% immedately after the UPS goes back
35
on-line, so you can't tell when it is really recharged.

on\(hyline, so you can't tell when it is really recharged.
37
79
Finally, some models give one value for the battery's nominal voltage and
38
80
yet actually have a nominal voltage slightly below that. This leads to
39
81
things such as the perpetual 98.7% charge on the author's Fortress 750,
40
even when it's been charging for weeks.

\fBups.conf\fR(8) to fix this.
