Here's the lug you would use for the inverter and batteries [ https://www.delcity.net/store/Straight-Tinned-Copper-Lugs/p_810763.h_796015.t_1 ]( https://www.delcity.net/store/Straight-Tinned-Copper-Lugs/p_810763.h_796015.t_1 )
 It doesn't say here, but on the bag I got, it specifically is listed for fine strand cables too.

 I have 3 crimpers that I use: one like Allan's for the large cable (2/0 and 4/0) , then a smaller, easier to handle one for #2 to #8.  
 For #10 and smaller, I use a Klein crimper with the indenter.

 I've had failures and repaired other people's problems with the hex crimpers.  In all cases, I recommend a crimper that has a V on one side and an indenting pin that pushes into the V.  
 I've taken apart factory cables from Outback, Trace, Midnite, etc, and they all use the V crimper style, not the hex type.

 All of these make good professional crimps.  I've tried several other crimpers that did not work as well.  Hex crimps can rip through heat shrink, while some ratcheting oval crimpers let the wire pull out after, etc.....  With the indent, it will always hold the wire, even with different types of wire and different lugs.

 1/4" ring by whatever size wire you choose. Del City is a good source - [ www.delcity.net ]( http://www.delcity.net ). #153145 is 1/4"/#10AWG; #254145 is same for #8 and #255145 for #6.
 Standard indent crimper for non-insulated terminals, not the automotive type. Mine is a Klein.

Hey Wrenches,
I'm doing an upgrade to an Outback VFX series off-grid system with the flexware boxes.  What type/brand of ring connectors and crimpers do you all use for the DC breakers with the post terminals?

 Thanks,
Will
