I need some assistance/advice on how to solve a very unstable grid set point on a 2 phase Multiplus-II system with 2 Multis per phase and 95KWh storage system. The ESS assistant has been loaded for this installation. The multiples's on phase 1 keep converting grid power to DC to use on phase 2 despite no load being on phase 1. Also when ESS is being charged the system keeps feeding back to the grid significant power, and even worst when the inverters are loaded > 50%. If I set the grid set point to around 800W the then the system primarily feeds the load from the grid and not the solar charge controllers and ESS. Has anybody every had a similar issue and how was it solved?
