Can anyone explain the difference between Min SoC and Min SoC (on grid)?

I can't seem to find any explanations in the manuals.

minSoC is the minimum allowable safe state of charge for the battery

minSoC on grid is the minimum you want the battery to fall to whilst running on grid power.

The reason for the difference is that some people use the EPS (backup) power option and to do this effectively you need to leave a surplus to run off just in case the grid power is to fail.

If you don't have EPS then it is best to set both minsoc options to the same (10%)
