BTW, the ROCB also uses both of your AUX relay options. Got called in to evaluate a 6 Radian AC Coupled configuration with no charger controllers and 6 Fronuis. What a cluster *%#%(^. The project was a very bad design from the beginning. That's what happens when you ask a grid tied installer to give you a battery back up solution.
