most efficient way to light, given a 48vdc pv system? - Page 8

 



Really?  Which "pdf" and which "site" are you looking at?  I looked at the
manuals for the units at the respective manufacturer's web sites.  In the
Outback manuals, I saw data for the 12 & 24V unit; for the Trace SW, the
manual shows the 48V unit specifically.  (Both are in the Inverter setup
section).

For the Outback 12V:  "This setting has a range between 9.0 vdc and
12.0 vdc in 0.1 vdc increments."

For the 24V:  "This setting has a range between 18.0 vdc and
24.0 vdc in 0.2 vdc increments."

Did you find something that stated the LBCO for a 48V unit would be other
than "a range between 36.0 vdc and 48.0 vdc in 0.4 vdc increments" ??

For the Trace SW units, for the 48V model Range: 32.0-64.0.  Again, this is
directly from the manual.

And I can guarantee that, in practice, the 24V is in fact that adjustable.
I have one.

And I have an SW5548 which also has the LBCO adjustable as per the manual
which I posted.

I wonder what George was looking at to come up with different values.

Can post the PDF spec sheet to you if you want. Or you can get from the

George , here is the exact links and pages,

http://www.outbackpower.com/pdfs_manuals/Grid-Tie_manual_7_1.pdf

Page 44 , menu Low Battery Cut-Out

Its listed as 18.0 to 24 Volts DC (for a 24 volts inverter) , so Ron is
correct , its 36 volts for an 48Volt inverter

http://www.xantrex.com/web/id/602/docserve.asp

page 54 of the SW-series manual

Range 32.0 to 64.0 for Low Battery Cutoff

Again , Ron is correct
