Matching Outback inverers on powerboard? [RE-wrenches]

[solareagle]

<x-flowed>

Hi William,
Thanks for your reply but what I may be doing is adding one inverter to 
a PS2 power panel that already has one inverter - therefore making a 
stacked 3524 system. Now I can buy the stacked system complete from one 
supplier and avoid the hassle of wiring in a second inverter -OR- from 
another supplier I can buy a single 3524 on a power panel and a 
separate inverter and mount it on the power panel to make a stacked 
3524 system. There is a price benefit to doing it this way but I'm 
wondering if I'm opening a can of worms and should just buy the factory 
assembled & wired half rack?

Sorry if I'm not explaining this well, I find the naming conventions 
for the Outback power panels to be somewhat confusing. Outback calls 
them one thing, (actually they don't seem to call them anything they 
just want you to identify the components) - but my suppliers have 
different names for them.
