I use the MP2 in ESS mode 3 via Modbus to feed back power to the grid. I watched that sometimes the MP2 produces power peaks if the power setting is low for example 100W. In some cases this results in high reactiv power output of the inverter measured values 1200VAR capacitive. The inverter stays in this mode until i raise the power to higher values > 1000W than it works stable until the next sporadic peak (there can be hours in between) puts the inverter in that reactive mode. The MP2 was excanged with another MP2 with the same result. I hope that victron have a solution for that problem. This instability is not acceptable grid inverters.
