Just installed a Xantrex XW6048 and I am in need of an external signal that tells me when the is grid down - the XW has an AUX signal block that can only be activated when there is some battery condition/power level change. That was confirmed by the tech support staff and they couldn't come up with any other way to make this work.
Ulitmately I need to momentarily apply 12VDC to an external relay. If anyone has any ideas, I will appreciate hearing them.
PS - I have been contemplating a 240VAC fused relay circuit, but the relay will always be active when the grid is up - something just the opposite would be better???????????????
Many thanks, Nick
