Two SMA Sunny Boys to the left, two Sunny Islands to the right, and various protection devices, the AC Bus, and the grid connection with PE to local earth and grid neutral (TT) in the little box to the right.
Next step is to install the battery shelf on the floor and the conduit run below all the gubbins.
Haha! I'll be "discovering" Jupiter when I replace the little box to the right with an automatic transfer switch (which I'm building with a friend) controlled by the master Sunny Island (all pole disconnect for the grid, but it gets more complicated for TN earthing as you also have to have contactors for switching between grid neutral and local earth).
It's for allowing both grid-tie with injection and battery backup when the grid fails.
