I will use a sparky for the actual wiring (I’ve been warning him, the longer he avoids me the bigger the job gets
), but I’ll set the wall box and it’s neater, less rushed when I do it. Tas wall boxes are a different size to NSW, taller and a bit narrower. Ideally if a complying enclosure was 450-500 square by 250 it
should suffice. I haven’t seen a dimensioned diagram of a solar charge controller and specific breakers for ≅15kW output.
