We use a grid parallel 3-ph system with 3 Quattro-48 10000-140-100/100 inverters and 4 Smart 25.6V-200Ah batteries. The ESS description states that in the External control mode, it is possible to forcibly set the system to the power supply mode (discharging to the grid) or charging from the grid using external control. Where can I find information on how to implement this mode, what additional equipment or devices are needed for this? We would like to implement a mode in which, at a certain time, the system power output to the grid (for example, in the amount of 20 kW for 1 hour). Is it possible to configure the system for uneven output in phases, that is, 7 kW is output to the L1 phase, 2 kW is output to the L2 phase, and 1 kW is output to the L3 phase. Is it possible, when issuing one phase, to charging he other phase to discharging mode from the grid? If possible, where can I find detailed information on configuring the system.
