<DIV>Joel,</DIV>
<DIV> </DIV>
<DIV>The SMA SWR2500U inverter has been a long discontinued model. If you want
to use an SMA inverter, go to the SMA website to use their excellent sizing
program. Plug in the module, and your record minimum and average maximum temps
for the site, and look for a current model inverter that will work. All of the
"U" series inverters (except for the 700U) are discontinued models, and the "US"
series are the current models.</DIV>
<DIV> </DIV>
<DIV>If your min temp is not below 14⁰F, it looks like you can use all 24 in one
series string with the 4000US inverter, but that gets you awfully close to
600VDC (595VDC) at 14⁰F. You might want to play it safe and drop one of the
modules. Unfortunately, none of the SMA inverters will operate with only 12
modules in a string (with two strings). However, a Fronius IG-3000 will, so you
might want to go with that, although it has a lower efficiency.</DIV>

<DIV> </DIV>
<DIV>Wrenches,</DIV>
<DIV> </DIV>
<DIV>Our customer has 24 each Kyocera KC130 modules and wants to go
grid-tied.</DIV>
<DIV>Can he use an SMA SWR2500U inverter with the fan kit? Is there a
better</DIV>
<DIV>inverter that will use all of his modules? If you have an SWR2500U or
a</DIV>
<DIV>better inverter option for sale, please contact me off-list. Thank you
very</DIV>
<DIV>much.</DIV>
