Exiting the box are the wires that provide the Soleral with AC power. One wire goes to an ac outlet that the converter plugs into and the other goes to the fuse panel inside the Solera.
As for the little white box, I think that is for the circuit board controlling the water heater...may be mistaken on this but it seems logical with all the wires going in that direction.
This is how my Solera is wired and yours, I would think, would be similar...
Thanks Slowmovin. I'm guessing your right on the controller box zip striped to the HW tank as well. There are only low voltage wires going into that, so it must be a controller of sorts.
