I need some help, connected 4 x Multiplus II 5000 inverters in a 2 Phase 180degree System, 2 inverters in Parallel in each phase, 230V. Works very well. Question: when using Ignore AC function, I want to accept AC when the total of the 2 inverters per phase go over 8kW and return to battery when under 7.5kW, should I Set the first inverter in each phase, L1/AC1 and L2/AC2 to accept AC when over 8kW and ignore if under 7.5kW, or each inverter toe over 4kW and under 3.75kW?
