still be using the Radian inverter, but with all off grid inverters I will most
likely be distributing AC power via off the shelf AC load centers. In
Outback, Xantrex or Midnite BOS AC panels, if I want to install an AC Breaker it
takes 10 minutes (I like my lead runs to be very neat and this takes
time). If I want to install a breaker in a standard OTS AC panel, it takes
10 seconds to snap in a breaker. I have a design idea for using assignable
busses in BOS panels. Who wants to contact me first to talk about
exploring this idea???</FONT></SPAN></DIV>

Radian install<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV dir=ltr>
<DIV class=gmail_default>William,<BR><BR>The Radian was designed to be big
enough so that one inverter could handle most residential applications, but also
easy to parallel so that very large systems could be assembled by simply
repeating the same building blocks, similar to how installers build up 100kW PV
systems using string inverters. However, when you have systems of this
size the potential available fault currents become such that we wanted to move
away from using ganged breakers and metal sliding plates, especially when
double-pole, double-throw safety switches in a range of sizes, both automatic
and manual, are commonly available from many sources. <BR><BR>With larger
systems, the easiest way to meet 705.12 is to install a dedicated “Inverter
Combiner” AC load center fed by a supply side tap, similar to what is typically
done with larger grid-dependent PV systems. It just seems far more cost
effective to use standard, off-the-shelf components which are probably on your
truck already, rather than custom sheet metal sized for every possible inverter
combination. You could use a service-rated 6-12 panel for up to three
Radian inverters, or 8-16 for four, etc. Repeat an identical size panel on
the output to gather the inverter outputs, then send the combined feed to the
house protected load center. If you have a generator as a second AC
source, then pick up a third panel of the same size. </DIV>
<DIV class=gmail_default><BR></DIV>
<DIV class=gmail_default>While we designed the prewired GSLC enclosures to
provide a simple, quick solution for single inverter systems, we also offer the
bare GSLC for multiple inverter systems as well as to allow full customization.
Each GSLC has space for 18 AC or DC panel mount breakers. In a dual
inverter system like the one you're planning, we’ve seen some cool installations
where one GSLC has been assigned to AC, and one to PV. It works out pretty
slick. Each GSLC comes with its own shunt, so systems with up to three
Radians can easily use the multi-channel FLEXnet DC system monitor to give a
full SOC picture for all inputs and outputs.<BR><BR></DIV>
<DIV class=gmail_default>Each Radian inverter should have its own GSLC, and pick
up two 175A breakers per inverter. If the Inverter Combiner boxes are a
distance from the inverter stack or out of visual range, then you will need to
install 50A AC breakers for the appropriate inputs and outputs. Me
personally, I’d install these breakers at the inverter in all systems, as it
gives a positive disconnect directly related to the inverter directly above –
good peace of mind for anyone who comes later. There should be a finger’s
width of space between every pair of inverters, to allow clearance for the door
swing. <BR><BR></DIV>
<DIV class=gmail_default>Always update the firmware, as we’re constantly
expanding the capabilities and features. You don’t need a computer or
internet connection on the site if you download the latest firmware for both the
inverter and the MATE3, unzip it and copy to an SD card before going out into
the field. Update the MATE3 first. <BR><BR>I hope this helps, and
thanks everyone for the good feedback.<BR><BR><BR></DIV>

<DIV><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt"><BR>Allan,
thanks for adding us into the Wrenches discussion. We do have E-Panels set up
for single as well as dual Radians. I do not think OutBack does? We have a
Master/Slave set up where the Master has the AC bypass set up for two
inverters. OutBack makes you buy an additional outboard transfer switch. We
also have the large battery combiner made for connecting either two Radians or
four SMA Sunny Islands. OutBack does not have this.<U></U><U></U></SPAN>
<DIV>
<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">We
also have a 2 piece back plate that holds all of this stuff. OutBack
doesn’t.<U></U><U></U></SPAN></P>
<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">The
installers I have worked with prefer the MidNite E-Panel over the OutBack
since you can actually get to the breakers on the MidNite. It is a bit less
expensive also.<U></U><U></U></SPAN></P>

<P class=MsoNormal><FONT face="Times New Roman, Times, serif"><SPAN
style="FONT-SIZE: 11pt"><U></U>I would also suggest a couple of other
things... with four Radians, you need to be able to handle 1,400 amps of DC
current (each Radian uses 2 2/0 cables per pole and two 175A breakers). Robin
has worked with us to develop an 850 A DC disconnect system (four SI5048 with
125A DC breakers and one Radian at 350 A), and may be able to assist with this
greater need.<BR><U></U></SPAN></FONT></P>
<P class=MsoNormal><FONT face="Times New Roman, Times, serif"><SPAN
style="FONT-SIZE: 11pt"><U></U>Also, you mention a 200A DC recombiner - I
assume you are aware of the 60/80A limitation per controller, and that they
can't be paralleled on the input side.No reply
needed.<BR>Allan<U></U></SPAN></FONT><B><SPAN
