[RE-wrenches] Parallel Homegrid Stack'd Busbar

[Bradley Bassett]

Note that MidNite now also makes 2000A and 500A versions of their BCB. With
two Sol-Ark 15k you do need to use the 1000A version with 275A each
inverter. I can also confirm that you do need to use both of the battery
terminals in the Sol-Ark 15k for full power, or the Homegrid bus bars that
Jason shows.
