perhaps i am not understanding the set-up, but why feed a ups with a ups? 
doesnt the sunny island already provide ups capabilities for the loads 
connected to it?

Thats the best fix I've heard yet! 
Document then DUMP IT! With the power logger you would also be able to capture 
the transition from utility to SI for your home auto gusto see if he is able to 
accept the power quality too.

I recently worked on a Sunny Island/Sunny Boy system in a nearby island, that 
powered and protected a complete Home Automation system, including the airco 
system keeping it cool. I had to restart the Sunny Islands to sort out a COMS 
problem, which revealed some IT issues. It turns out the Sunny Island system 
had kept it all running smoothly for about four years without an issue so 
no-one had realized some of the firmware was crunched. I would get rid of the 
UPS altogether and that ends the problem.

I have in the past have used the Fluke power logger 1735 , It will monitor 1/3 
phases voltages spikes/dips in V, A, Hz , +++ AND one is able to print out a 
time line of all the "occurrences" that may trip the UPS. I rent this from some 
folks in Texas quite reasonable ~ $230/month or weekly too. NO MORE finger 
pointing!
 I found that when the generator was charging the batteries, the UPS's 
acceptable voltage window was below the limits and began beeping, due to the 
poor voltage regulation of the gen under hi load/charging conditions.
Are you able to log the Hz as well as the voltages? The ups sometimes have very 
close voltage windows that they work within. The SI/SB's power quality should 
NOT be the issue. With this power logger one is able to see a time line and 
figure out what it operating at the time of "fault/beep" utility power or 
generator power. Contact me off list for rental contact info or if you would 
like to see what the graphs look like. Tool is easy to use and VERY informative.

Friends:
 
I am still having a pi$$ing match with the company that installed the expensive 
home entertainment system for a client over the issue of power quality.  The 
UPS beeps frequently and the AV system crashes now and then.  The lead 
installer has copped an attitude and is blaming the Sunny Island / Sunny Boy / 
Generac system for the AV system problems.  The UPS emails reports in flurries 
that indicate a “power failure” has occurred. 
 
I have a Dataq data acquisition system sampling at a rate that allows me to see 
the individual cycles on the system output on one of three phases.  During the 
time that a power failure is reported to have occurred each and every cycle 
looks great.  I know this is not a definitive test of power quality so I upped 
my game.  I bought a Fluke VR1710 power monitor and I am recording power 
quality from the same receptacle that feeds the UPS.
 
I have some log files from the Fluke Power Log software but the instructions 
are not that great and I don’t know how to interpret the data.  Do any of you 
have any experience with this software and could possibly advise me?
 
In a more general sense, how good is power to be called “good”?  I have done 
some research and the industry material is a bit overwhelming.  Does anyone 
have a short answer?
 
And lastly, even though the UPS is beeping, if it is doing what it is designed 
to do, the power quality should not be an issue because the UPS corrects for 
any problems.  (Actually the UPS was beeping—the best move in this situation 
was to mute the annunciator so at least the homeowner is not hearing the 
beeper.)
 
I know others of you are dealing with the same problems because it came up on 
this forum.  I am interested in an approach that verifies the Sunny Islands are 
producing adequately good power, or not, so I can either address the problem or 
get the AV guy off my rear end.
 
Thanks in advance.
 
William
