[QUOTE="Sidewinder, post: 444258, member: 9512"] Yeah, looking at this from the opposite way to say a machinery power supply for controls would be separated, so to get ADS, you have to earth the dc -ve at the output of the PSU. The way I am interpreting this is that the dc -ve is earthed, I would expect separation in the dc-ac inverter, thus I am expecting the ac side not to be connected to the dc side directly, thus I would expect that there is no earth path on the ac side as this is drawn. The data needs to come from the inverter OEM. I would also be a bit wary of all of these separate supplies, as they would be slightly out of sync and you could get a potential between the lives of different circuits. I would expect the ac to be earthed, and all the earthing interconnected though. [/QUOTE]
