[QUOTE="the doctor, post: 367377, member: 75"] Hi Sidewinder, I have not shown the earth on the inverter for clarity. However the thing is built, the frame is an exposed conductive part with the magic bit tucked inside. The drawing is a general show of the point made way back by Phoenix. As long as there is no insulation fault anywhere and it is is as drawn it is impossible to be shocked from a pumping PV and a tripped RCD. It is effectively an IT system. I am not saying this is good or cool, but stating the way it appears to be. In the regs, they talk about 'single fault conditions'. This situation is exactly that. If you somehow made contact with the neutral side that would be classed as a second fault. You cannot protect against a second fault because it would be the equivalent of sticking two fingers in a lamp holder. [/QUOTE]
