<DIV><FONT size=2 face=Arial>Thank you for the quick reply. I have been
using the 108 VAC default setting since 1998. I'll try 95 VAC.</FONT></DIV>

<DIV><FONT size=2 face=Arial>It is interesting to hear other wrenches comment on
utility low and high voltage. Power factor control is
another challenge for some utility companies. On the other hand, they
hold the RE industry to very tight power quality standards. I have tried to
get Los Angeles Department of Water & Power (LADWP) and Southern California
Edison (SCE) to keep their voltage within spec and improve their power
factor. Their responses are similar to asking City Hall to fix
potholes in the road. Sometimes they do. Sometimes they don't get a round
tuit for a while. SCE power is generally ok except in old neighborhoods
with wires and transformers over 40 years old. Forget about LADWP.
They are off on another planet. The smaller municipal utilities in southern
California are pretty good at managing power quality. Fortunately, today's
inverters can be adjusted manually. Perhaps some day inverters and loads
will self-compensate for less than stellar grid power quality.</FONT></DIV>

[RE-wrenches] Low grid voltage fix<BR>From: "Joel Davidson" <<A

Christmas time again in Southern California Edison (SCE) territory <BR>which
means low insolation and high regional electric consumption. Every <BR>night
SCE voltage drops to around 105 VAC or lower. Our grid-tie SW4048
<BR>inverter sees SCE's low voltage as a brownout and switches to autonomous
<BR>mode which is normal. However, we have only 4 kWh of battery storage so
the <BR>combination of nightly brownouts and a series of cloudy days
eventually <BR>depletes our battery bank causing the inverter to do a
low-voltage shut down <BR>which is normal. Power goes off in our home and we
have to switch over to <BR>SCE power, reset the inverter, and wait until the
battery bank is recharged. <BR>How do we set the SW4048 to accept as low as
100 VAC from the grid before <BR>switching to autonomous mode?<BR><BR>Joel
