RikH Posted August 21, 2020 Posted August 21, 2020 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? Quote

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. Quote
