InsightHome power relay activation?

[Mike10825]

In the "AC Coupled Systems with Conext XW+/SW: Solutions Guide", page 9, 3rd paragraph, it recommends "...an over-voltage protection relay to disconnect the AC coupled PV inverter in the event that the voltage reaches or exceeds the battery's maximum operating voltage".... and goes on to give more details. The Guide, furthermore, says, "The relay can be triggered by the 12 Volt Aux port of the Conext XW+, set up to trigger on high battery cutout (HBCO)". Apparently there is no such 12 volt Aux port on my Conext SW4024, however, my InsightHome device has a 12 pin connector that includes a 0-40VDC digital output.   Is it possible to use this?  If so, how?
