I have a 6.5kwh system with one Growatt 2000us battery. Our grid cuts out for an hour or two most days, night and/or day. On a sunny day, clearly the panels produce more power than the single battery, but when the grid cuts out, my system cuts off the solar production and reverts to battery. I would prefer, when the panels produce enough, to use their output first, supplementing if necessary with the battery. Is this possible? My main settings choices are grid first, batt first, load first, and my supplier has selected batt first. (solar comes back on only 5 minutes after the grid is restored).
