Grid Tie Solar system

Hello. . .
 
I am researching a Grid Tie Solar system - no batteries.  I have selected the PV array - 24Vdc/2000Watt.  I can select a breaker panel for DC disconnects.  I think the Sunny Boy SB-2100 Inverter will work.
 
What else do I need?
 
What other equipment?
 
Where can I get a complete system diagram?
 
Thank you,
 
John

Re: Grid Tie Solar system

sma 2100 has gone extinct as a result of may 2007 rewrite of UL 1741 listing.  although theoretically it would work, it is not available in the wild as far as i know, unless somebody has a stash in their closet.

a breaker panel will not suffice for dc disconnect unless it is rated to 600vdc, which it likely is not.

take a look at the schematic on this page.

not totally complete, but really close.  contains all major components necessary for that system (1 series string)

here is an example with more than one series string of modules and an SMA inverter.
