.SH NAME  
bestups \- Driver for Best Power / SOLA (Phoenixtec protocol) UPS equipment
.SH NOTE
This man page only documents the hardware-specific features of the
bestups driver.  For information about the core driver, see  
\fBnutupsdrv\fR(8).

.SH SUPPORTED HARDWARE
bestups was designed to monitor Best Power UPS hardware like the Fortress,
Fortress Telecom, and Patriot Pro.  It also recognizes and supports SOLA
units such as the 520 and 620.  

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.  Try the bestfort
driver if this one does not detect your UPS.

.SH EXTRA ARGUMENTS

This driver does not support any extra settings in the    
\fBups.conf\fR(5).

.SH BUGS

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.

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.
