    Any lead acid probably gets "stressed" with less than 12/24/48 volts resting, and a good start point for cut-off is around 11.5/23.0/56.0 volts -- But, that is all, of course temperature and load dependent.

    Buy an Outback inverter and use its LVD to switch to grid power. Much simpler and more likely to work than attempting to rig a relay capable of handling the AC input and driving it off the AUX port of the FM80. For one thing the AUX port will not drive a very large relay, so you'd end up with two relays. More wire, more complexity, more power needed to run the triggers.

    buy an outback inverter is easy solusion to use its LVD, but not easy to import radian international series here..

    with fm80 aux port, its end up with 1 relays and 1 contactor for big amp, easy wiring, low power needed for contactor.

    now just to take care battery range voltage only. i set delay time for 30 sec before action.
    i use 47,5 volt for low trip by pass to grid, and 56 volt for release grid. its Ok for AGM battery ? need suggestion here..

    thanks

    This thread from 6 years ago on the Outback forum describes it a little bit:

    http://www.outbackpower.com/forum/viewtopic.php?f=15&t=2867&start=0
    OutBack Power System GTFX/GVFX Grid-tie settings
    In a GTFX/GVFX Series Inverter/Charger, Charge Controller, HUB, and MATE installation set the Charge Controller to GT mode in the ADVANCED MENU. GT mode allows the GTFX/GVFX to manage the Charge Controller float setting ensuring the Charge Controller is always keeping the battery above the sell voltage of the GTFX/GVFX.
