So the RV-C info sent on the network, known as PGN's or DGN's is standardized and well documented (RV-C Specification Document - December 2022 Version | rv-c.com). Transfer switch info would typically be contained in the ATS_AC_STATUS_1, ATS_AC_STATUS_2, ATS_AC_STATUS_3, ATS_AC_STATUS_4 PGN's. These contain all kinds of info about AC voltage, current, phase, frequency, AC powerline faults, etc. Glad to hear the RVC3 model is compatible, it should be if they conform to the standards.

However, I would be a little concerned about this info Stu posted "[The RVC3] continuously measures shore power to switch to generator power when shore power electrical conditions are beyond limits". If there is a way you can disable that feature I would suggest you do it. Hopefully it is disabled by default. The auto gen start/stop logic is already enabled elsewhere on your network so if there are two sources trying to control the generator during an AC outage or fault situation, that could get messy.

In round dollars, what did that 3rd version set you back? Just wondering...
