Solar Postive Battery Connection
Hey guys. I'm in the process of putting the final touches on my 5er solar project. 4 Kyocera 130 watt panels, Morningstar TM-45 Charge Controller, Bogart TM-2030 Battery Monitor, Magnum MMS1012 invert...

you can connect all the outgoing wires to one positve post and one negative post, and all the incoming wires from the chargers to the opposite pos and neg posts...
the batteries wired parallel will be fine this way and keep the posts organized...
just make sure each "pair" of wires are connected to the posts of opposite batteries, and not to the posts of the same battery.
as for the solar array of 4 130w panels, 2 batts will work without any problem, but 3 or 4 12v batts would allow you to get the most from the system... you are being short changed on your investment having only two batteries with that many potential amps...
A "bus" is something that "takes it all", while a "buss" is a kiss.
The usual rule is to discharge and charge the batts from the same posts. You can have solar charging at the same time as load discharging. I am not sure at all, if the battery can keep track of which way the electrons ought to be going if you use opposite posts like that.
On the neg bus, the OP has a Trimetric, so his shunt is the neg bus bar. One fat wire from it to the batt neg post. The Tri shunt bolt can also run out of height for more ring lugs, so that might mean an additional bus bar on the neg side. The inverter can take the converter or solar to its pos terminal too, to help with bussing.
