We have two 8K Quattros in parallel (master slave) connected with a 100A autotransformer. We notice that when the inverters are in charge "Bulk" mode or very heavy load we measure current on the ground coming off the AT. We have enabled the ground relay within the AT / Quattro setup and connected the wire from the Quattro master to the AT. Thoughts on what is causing the leak while the Quattros are in charge mode? It happens with shore power or gen.
