Hi Bob,

If you want to use a bus bar assembly I hooked up 10 VFX3648's to 2 strings
of Rolls 2-KS-33's using Ilsco insulated 4/0 x 14 port splice taps/bars.
This is a really neat way to do a 4/0 bus bar. They make these
splicer/reducers from two hole to 14 hole. They were around $270 for the
pair and well worth it.

Subject: Battery strings [RE-wrenches]



I am putting together a pack of 12 L-16's @ 24 volts and am wondering if
there is a definite opinion on what works better, connecting at the corners
of the pack or running each string to it's own buss bar and from there to
the inverter. 
I have seen failures of the major positive and negative when corner
connected.  I assume from the all the banks current running through the
connections. I have also heard suggestions to rearrange the battery bank
during it's life. (too much like work) 
Has anyone had better luck with each string going to a bus bar then to the
inverter? Similar to the "big buss" that Outback used to make?
 
Thanks,
Bob
