<DIV><STRONG><FONT size=2 face=Tahoma>I encountered another, potentially very
serious, CO problem yesterday when I equalized my still-new solar batteries with
the exact directions of both my solar electrician and the relevant
manual.</FONT></STRONG></DIV>
<DIV><STRONG><FONT size=2 face=Tahoma></FONT></STRONG> </DIV>
<DIV><STRONG><FONT size=2 face=Tahoma>The batteries are in an interior utility
room but have a “Power Vent” that goes from above the batteries to the
exterior.</FONT></STRONG></DIV>
<DIV><STRONG><FONT size=2 face=Tahoma></FONT></STRONG> </DIV>
<DIV><STRONG><FONT size=2 face=Tahoma>I didn’t check CO while equalizing, but
shortly after I turned off the generator (which ran for two hours in the
equalize phase), my upstairs digital meter read over 60 (must have just recently
reached as the alarms hadn’t gone off yet anywhere—I have seven CO meters/alarms
in this rather small house and none had gone off yet), so I checked down in the
utility room and the meter was rising towards 300! I quickly opened the utility
room door and the nearby garage doors to air the room out. It took a long time
for both downstairs and upstairs to clear of CO, however—the meters would go to
zero, I’d close the windows/doors, then the numbers would go back up even though
the generator was off, equalizing was completed by then).</FONT></STRONG></DIV>
<DIV><STRONG><FONT size=2 face=Tahoma></FONT></STRONG> </DIV>
<DIV><STRONG><FONT size=2 face=Tahoma>I’m calling my solar electrician early
this week to discuss this but I’d appreciate any thoughts/knowledge on this. The
batteries are two huge industrial Deka solars so they’re not in a battery box
but rather their own box. (If you know the size of these, you’ll understand what
I’m saying—they do not fit in a battery box like typical L16s or other small
batteries but come in their own case.)</FONT></STRONG></DIV>
<DIV><STRONG><FONT size=2 face=Tahoma></FONT></STRONG> </DIV>
<DIV><STRONG><FONT size=2 face=Tahoma>Obviously next time I equalize I’ll watch
the numbers closely and keep windows and doors open as needed but obviously I’d
like to eliminate the problem. Seems to me either the Power Vent isn’t working
properly, wasn’t installed properly perhaps, or something else isn’t right as
even with batteries venting, I don’t think CO levels in the room should get so
high.</FONT></STRONG></DIV></DIV></DIV></BODY></HTML>
