Hi, Daniel~ If your client has quantity six of the L16H batteries, that's only a 36 volt string, not 48 volts. Let's hope this is only a typo.<div><br></div><div>The only vapor "emissions" likely from a group of floodies are oxygen & hydrogen...then there's dilute sulfuric acid mist...but no carbon component. <div>

<p class="MsoNormal">I was emailed recently by someone in my area saying that she
thinks here battery bank is going bad and poisoning her home…. My firm
did not install her off grid system. Her original installer will not respond.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">She has an 6yr old battery bank w/ 6 Trojan L16H’s (48V).
The system has 1.2kw of shell solar modules with an MX60 CC and FX Inverter.
She noticed feeling ill when in the basement where the system electronics were
installed, so she got out a combustion gas analyzer, (she is a home energy
auditor), and recorded over 500 ppm CO in the battery bank storage closet, not
the battery box, but the closet that stores the outback system. That is over
double the concentration that the US Consumer Product Safety Commission considers
deathly toxic. She reports this has been going on for the last 1-2 months. There
is one battery box in this closet, with a 3” PVC vent pipe going up to
the roof. There is no power vent.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Has anyone heard of a flooded lead acid battery bank emitting
CO? I did not think that a lead/sulfur based battery was capable of this. Is it
possible that her combustion gas analyzer is mis-interpreting some other gas as
CO?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We already plan to install a power vent at minimum, and to closely
inspect her ventilation system and improve it as needed. Just curious if anyone
else has seen this happen before.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks,</p>
