By cycling, I mean daily (or periodic) Absorb<SPAN
class=578251701-20022012> as I mentioned in the email</SPAN>, not
loading/draining the battery (other than the clear statement to test to see if
the system actually works as a backup system<SPAN class=578251701-20022012>
every once in a while</SPAN>).<SPAN class=578251701-20022012> No real deep
draining necessary. For instance, after some months without issue, one customer
called in a panic because the electricity did go off one night and they had no
backup. Turns out, somehow they turned off the "Inverter" function. Easy
solution, press a few buttons, etc. to turn on the
inverter.</SPAN></FONT></FONT></FONT></SPAN></DIV>

<DIV><SPAN class=578251701-20022012><FONT color=#0000ff size=2 face=Arial>Maybe
all I need is a Time function attached to Selling, like the Charge function has
on some brands. Who knows.</FONT></SPAN></DIV>

<DIV><SPAN class=578251701-20022012><FONT color=#0000ff size=2 face=Arial>It is
clear that FLAs have a self discharge and some percent of capacity is obtained
during Absorb, so a long term Float only might reduce some of the batteries
capacity.</FONT></SPAN></DIV>

face=Arial>Anyway, Outback does have the "Absorb before Sell" function
when using the FN-DC in the system. Not sure about the newer version of
hardware. The "Parameters Met" settings gave me fits until I figured it out.
Plus, the FN-DC is not free.</FONT></SPAN></DIV>

<DIV><SPAN class=578251701-20022012><FONT color=#0000ff size=2 face=Arial>The XW
has a function for Absorb before/during sell. I think it requires a XW CC. We
use every brand of CC appropriate for the site. Also, the setup instructions
are weird in my mind since it requires the Grid Support Voltage to
programmed to very high value. I wish they would just have added the function
"Enhanced Interactive Mode = Enable", etc. </FONT></SPAN></DIV>

Maverick,<BR>> <BR>> "But you would think after 20 years, inverter
manufacturers would make some<BR>> software similar to generator cycling to
handle this cycling issue. "<BR>> <BR>> I believe that the XW Inverters
have this ability in sell mode. There is<BR>> traditional sell voltage. And
then there is a setting that puts the batteries<BR>> through a traditional
bulk cycle while still "selling" back any excess energy.<BR>> The next
question would be, is this better for battery longevity. Seems like a<BR>>
hybrid of the two would be ideal.<BR>> <BR>> Doug Wells<BR>> The Solar
