<p>I'd add at least a small amount of DC coupled charging so that if
the main AC trips off for any reason, the batteries will still get
a charge. I've done a few SMA setups and having an heavy AC load
or low battery situation shut down all battery charging is a
serious problem with AC coupled setups. Sorry I don't have a
Webbox.<br>

<div style="font-family: Helvetica,Arial,sans-serif;">Hi Folks,<br>
<br>
Well I've designed and sold an 18 KW Sunny Island / Sunny Boy
system for the Carribean but SMA informs me that they have
nothing to replace the discontinued Sunny Webbox for another
several months.<br>
<br>
I can't simply tell my customer - "oh by the way - you know that
cadillac system I sold you and am installing in June? oh the
manufacturer has no monitoring solution for you"! Especially
after repeating over and over again the most important part of
any off-grid system is the battery % gauge in the kitchen!!!<br>
<br>
So if anyone has a SUNNY WEBBOX out there - or knows where I can
get one. Please contact me OFFLIST.<br>
<br>
Thanks so!<br>
<br>
Best<br>
<br>
Jeff<br>
