Hello,
I have system with three Multipluses II 3000 in parallel connected to grid with MPPT Solar Charger 250/85, two Seplos 5 kWh batteries, Venux GX and ET112 connected to Venus GX in Grid Meter role. My FeedIn limit is 3700W. Because I have spot prices I ussually sell some battery capacity in highest hours with setting Grid Point to -3500W with disabled Peek shaving function. Grid limitation is set to 3700W. For setting reguested parameters I’m using Modbus communication from PLC Loxone with registers 2700, 2706 and 2707 as is described is ESS manual mode 2. My problem is that system is not able to limit Grid FeedIn power to 3700W even I set grid setpoint only to -3500W. If I’m checking power delivered to grid it is oscilating between 3600W and 3800W. This problem ussualy happends when system is combining power from MPPT charger and batteries. Is this behavior normal or is something wrong in my system? What is the priority of ESS parameters?
Thank you
