Hi Esteemed Wrenches,<br>
<br>
Does anyone have an experience with using the BatFan relay function on
the <span style="display: inline; font-size: inherit; padding: 0px;"
class="__postbox-detected-content __postbox-detected-date"
__postbox-detected-content="__postbox-detected-date"><span
style="display: inline; font-size: inherit; padding: 0px;"

__postbox-detected-content="__postbox-detected-date">Sunny</span></span>
Island Relays?<br>
<br>
I'm familiar with setting a voltage point for a relay to control a
battery box fan but I'm unfamiliar with how the BatFan functions works.<br>
<br>
The only setting I can find on the SI menus related to BatFan is battery
temp. But then elsewhere I read that the SI will turn on the fan
anytime there is gassing. Surely it can't be determining when it's
gassing from only battery temp?<br>
<br>
Or like in true SI fashion is there some complicated and thorough
algorithm functioning that's is tracking the charge cycles and voltage?
But no where to set those parameters?<br>
<br>
Also - I've read through a few conflicting methedologies for calculating
CFM needed for any given battery bank to clear the Hydrogen.<br>
<br>
Zephyr says that there fans are designed for battery packs 2000
Amp-Hours or less charging at 150 Amps or less.<br>
<br>
I have a largish off-grid system (18KW) with 2490 AH (20hr) of batts set
to charge at 200 Amps max.<br>
<br>
Should I be revisiting those calcs and see if I can find a definitive
methodology or will using <span style="display: inline; font-size:
inherit; padding: 0px;" class="__postbox-detected-content
__postbox-detected-date"
__postbox-detected-content="__postbox-detected-date">2 48</span> Volt
Zephyrs do the trick?<br>
<br>
Thanks!<br>
