My customers system LCBO is set at 48.0 / 6 secs. As long as AGS is enabled and working, the voltage won't drop that low using the parameters in this screenshot.

For some reason (that I never got an answer to from Outback or Blue Planet) older FX inverters are not compatible with Blue Ion LFP batteries.
