Hi. I have strange issue with system that was running 3 multipluses 2 5000/48 one per phase but was upgraded to 2 multipluses 2 per phase to increase power. Previously 3 inverters were able to keep charging and discharging so power taken or sent to grid was ± 50W from grid setpoint which meant daily consumption from grid in sunny day was below 1kwh. After adding additional inverters this mechanism seem to not work well - grid setpoint seems like suggestion and power consumed / fed to grid in in ± 4000W ballpark which is directly affected by current power of inverters (big inverter power = big deviation). I tried using external current transducer on inverters but it didnt work at all (i changed each inverter settings in veconfig). Batteries are 18x pytes ebox 48100 so i dont think that they are limiting factor ( basically all the time discharge / charge current limit 900A so well within required) AC cables length at inverter ac out 1 in within 2cm. On cables on Ac in are about 80cm differences. Can this be caused by grid code or some setting?
