In a domestic installation in the Czech Republic of a photovoltaic power plant, the battery is cyclically discharged into the grid and then charged in a cycle of about 1 minute. The production to the grid is enabled (14.4Kw), the battery is charged to 100% at the beginning of the cycle, discharged to 99% and charged again to 100%. Occasionally, the production of the array connected directly to the Victron is further reduced, which can be easily controlled by the Victron (There is another 3-F PV Power Plant connected to the AC OUT, which is reduced by the Victron only during islanded operation and excess power). I have no idea what this could be. (3x Multiplus II 5000, cerbo-s)
