- 88: Power, Site stn2, Wed 12-Dec-2001 08:31:45 MST, Changed Icharge monitor to Iwind/Isolar
Monday, 10Dec01, ~14:30 (20:30Z)
New EVE configuration: fmt0113
Purpose: Change in Battery/Charge Box.
Added new charging current shunt to monitor PV / Wind
separately.
New Base Parameters:
Channel 100 same 'Vbatt'
Channel 101 now 'Iwind' was 'Icharge'
Channel 102 same 'Iload'
Channel 103 new 'Isolar'
Operations Notes:
1) There will be 'noise' on Iload when the wind generator kicks
in, I expect that. The cause appears to be that the shunt is
on the 'ground' line and there are other return paths for the
real charging current, which is through the Iload shunt.
I need to decide how and whether or not to attack that problem
(not too keen on having the shunt on the '+12' side and being
routed to EVE.)
Result: Noise / false reading on Iload when wind generator is going.
Iwind will be lower than the actual charging current.
2) Still no monitor on the charge divert circuit
for when the batteries are full and the juice gets sent to the
dummy load.

- 57: Power, Site stn2, Thu 06-Dec-2001 12:21:22 MST, changed wind gen pot again
I now have the pot all the way clockwise. This should be the high voltage
setting. The prop was much happier and went from spinning slowly to quite fast.
I note that Icharge went up to 14A! Hopefully, this is a good setting to leave
it at.
- 35: Power, Site stn2, Mon 03-Dec-2001 16:39:30 MST, wind generator pot turned
I just changed the pot on the wind generator. Hopefully, this will improve the amount of power we get out of it. I the pot was almost completely clockwise, which would have been about 17.8 V. I changed it to the middle, which should be about 15.8 V. We'll see tomorrow if this helped (if the winds cooperate,
they just died).
P.S. winds overnight were 3-4 m/s, and Icharge was 0. I think that this is an
inconclusive test.

To run UPS program:
su -
cd /usr/lib/powerchute
./xpowerchute
Under Configuration->Event Actions
UPS On Battery

Low Battery Condition

will shut down server after 30 seconds
- 6: Power, Site base, Thu 15-Nov-2001 05:59:36 GMT, UPS software
The black cable with DB9 connectors should be connected between
the UPS and the serial port connection on the back of the dell.
The UPS monitor software runs automatically on bootup.
I have tested it with the Smart-UPS 620. I don't know if the
software needs to be reconfigured to use with the bigger UPS.
The software and log files are in /usr/lib/powerchute.
For display, run: /usr/lib/powerchute/xpowerchute
To reconfigure (if you switch to a bigger ups): Config.sh
The log files are:
powerchute.log # power events
powerchute.dat # time series of voltage, etc - potentially useful!
