Not-a-Gutter could be used with four SI’s. He was sure that you could
use two on top and two on the bottom, but that did not work for me due to size
restrictions. He was then going to look at the possibility of placing two on
top and one on each end of the gutter. You may want to check it out!<o:p></o:p></span></font></p>

it, the DC switch on the SI is really an on off switch and not a circuit
breaker. SMA recommends that the system has other overcurrent
protection. The main value of the DC switch that I could see is that it
provides an easier re-set point. (There are some power saving conditions
that require re-setting rather than auto-re-start.)<u5:p></u5:p></span></font><o:p></o:p></p>

Since Outback has in their catalog using the Flexware mounted in this
configuration, I would say the breakers are fine to be mounted in this
fashion. Worth checking though, of course. I do know that you are
not supposed to mount the DC breakers upside down (such as on the bottom of the
flexware, where you would have to reach under the can to operate the
breaker…..)<u5:p></u5:p></span></font><o:p></o:p></p>

<br>
(1) Doesn't each Sunny Island unit already include a DC disconnect breaker for
the connection to battery?<br>
<br>
(2) Aren't those big DC breakers in the Outback boxes restricted for
"vertical installation only"?<br>

<p class=MsoNormal><font size=3 color=black face="Times New Roman"><span
style='font-size:12.0pt'>Hi Folks......we have an upcoming Sunny Island/Sunny
Boy AC Coupled system installation.....We have mostly done Outback and Xantrex
battery based systems.......and like the available supporting DC load centers
with main breakers and other DC load and charging breakers......<br>
What are folks using for the Sunny Island products? Outback Flexware DC 500's?
or 1000's?<br>
This particular system will consist of 4 Sunny Islands and therefore will need
four main breakers...... We primarily need a breaker box to locate our
main DC breakers coming from the battery bank.......Any advice, experiences
would be appreciated......<br>
<br>
Also on that note.....anyone wish to share any experience or advice on the GNB
Absolyte GX series batteries or the East Penn Deka UnigyII as a standby grid
connected back up battery bank....They both seem like they are good for
primarily hanging out in float with occasional deep discharges not negatively
affecting the health of the batteries.....This is the type of service we expect
the batteries will be in primarily......Any recommendations of one brand over
the other.....The vertical stacking seems convenient as far as space is
concerned.....maintenece free......any recommendations on a good supplier on
the west coast? Any other brands i should be looking at in the sealed
battery category for a fairly large Ah battery bank?<br>
100 thanks !<br>
