G'Day Mates! 

OutBack has recieved ETL listing to UL1741 on our new PV combiner.  It 
is rated for up to 600 VDC and is available with up to twelve 125 vdc 
circuit breakers (rated for load break/make) or eight 600 VDC touch safe 
fuse holders (non-load break/make).  Info is on our website under the 
product name "PSPV".  We are waiting for the official ETL stickers to 
ship - they are in stock already.  

The PSPV combiner is a NEMA 3R type enclosure but was approved for both 
vertical mount and inclined to as little as 14 degrees (3 in 12 pitch 
roof).  It is a powder coated aluminum box with removeable cover and 
lots of knockouts - eight 1/2 inch and a 3/4-1 inch in the bottom, a 
3/4-1 on each side and a 3/4-1 inch on the back.  The bottom and back 1 
inch knockouts can be punched up to 2" for larger cables.  

The PSPV combiner is shipped without the breakers or fuseholders 
installed - they are snap in on a din rail mount.  The PSPV box with the 
negative and positive busbars, ground lug and din rail mount for $139 
retail.  The 125 VDC breakers are $12 each retail and the 600 VDC fuse 
holders are $8 (from Grainger - part number Cooper-Bussman CHM1) and the 
fuses (UL 600 VDC Littlefuse KLM) are in the $6 to 8 price range 
(wholesale).  

We also have completed in house testing on a custom made 600 VDC six 
pole breaker which fits inside of the PSPV combiner and leaves enough 
room for a two pole AC breaker as well.  A dead front is provided inside 
on this special version to prevent accidental contact with live parts 
when operating the switches. 

The six poles on the DC disconnect breaker allows connection of six 48 
VDC nominal sub arrays - there is only 600 VDC once the breaker is 
closed. The poles can also be series connected to use as a "normal" 600 
VDC disconnect if you do not want to run all the wires to the PSSB 
location. Three additional spaces are included for the 600 VDC series 
fuse holders if required as well.   

The price on this special version (the "PSSB") is $249 retail including 
the DC load break disconnect switch) and the Nema 3R enclosure with 
deadfront.  The AC breaker is another $29 retail.  We hope to have this 
version listed and available in January of 2002.       

Feedback on the designs is always appreciated - contact me directly 
either by email or phone.
