[Nut-upsuser] battery.charge and other fixes needed for X-Power Tigra 1kVA

Thu May 10 07:11:55 UTC 2012

Hello all,

been 5 years since I posted on this list, glad to be back :)

I have a number of X-power Tigra 1kVA online UPS units. From some 
knowledgeable folks working for the local distributor, I learnt that 
from inside this looked like a Best 610 ups unit.

Before, I had this UPS hooked via serial to my Windows 2003 server. For 
monitoring, some winpilot/upspilot software was also provided. This 
software produced also a csv format log (upsdata.csv) that contained the 
following lines:

So I disabled this bundled software and installed the windows version 
NUT-Installer-2.6.3-3.msi, without the libusb option (since I had a 
serial UPS)

In ups.conf I used the following

[ups1]
driver = bestups
port = com1
id = 610,1000,230,230,10.0,36.0
nombattvolt=41.1
battvoltmult = 18

With regard to the id option, the 2nd, 3rd and 4th options seemed ok. 
Not sure about the fifth (10.0). And definitely not sure about the last 
(36.0). I used 36.0 because the Best 610-1000 lists 36V as the DC bus 
voltage. Not sure if that is correct or not. According to specs ( 
http://www.lexis.gr/upload/File/ProductBrochures/XPower/Tigrablack.pdf ) 
this Xpower ups has three (3) 12V batteries.

I used nombattvolt 41.1 since that seemed to be similar also to the Best 
610-1000. As for battvoltmult, I must say I also experimented here.

The bestups driver seems to run ok:

My questions are:

1) Any ideas on why battery.charge is set to -24.8 (note also the 
negative sign)

2) Anything else that should be corrected in ups.conf, in your opinion?

3) Regardless if the battery.charge is correct, will the system shutdown 
when battery charge is low?

4) In my FreeBSD installations, ups.log is written as a log, anything 
similar for Windows?

I understand that this is a large number of questions, please accept my 
apologies in advance.

With kind regards,

Michail.-
