Its 2 rails of 11 x 6 AWG, 2 x 4 AWG, 2 x 2 AWG per bus and the design is slightly different from the picture. A little google research before buying would have saved me some confusion. I was looking forward to using it as a regular battery/inverter/charge controller. Well I love the build quality. They look very solid and seem to have done a great job with what I had in mind, so another star for that.
