Infini Plus 5kW / MPI HYBRID 5K battery feed to grid possibility

Hello all, I came across the settings "Allow battery to feed-in to to the grid when PV is available/unavailable". In the first place what is this setting for? Seems quite useless.

On the other hand, is there a possibility to make the inverter empty the battery into the grid and if so how do I do that? Could be useful for testing purposes e.g. capacity test without losing the entire amount of energy. (In the Netherlands we still have netmetering so I can use the grid as a giant battery.) So if I empty the battery to the grid and later charge it from the same grid it could give a nice indication of  1.- the battery capacity 2.- the losses in the inverter whilst discharging and charging.

Has somebody done this? Maybe with another type or brand inverter?

I have a Sunsynk 8kW inverter and can discharge the battery to the grid. I can also limit the peak power it discharges to the grid.

I once tried it out at max 8kw but the max battery discharge rate is 111A (5 328W)

I also used to test how long it will take to get from 100% SOC to 20% SOC by setting the battery grid feed in rate to 500W.

That's what I would like to try as well but how?? Maybe @Youda or @Coulomb knows? Thanks for your reaction Achmat.
