I have an ESS system with the following components:
Cerbo GX as controller
SmartShunt 500A / (JKbms via serial connected capable for 200 amps)
Energy Meter ET340
Battery 280 Ah
Charging of the battery is not a problem, this is goiing with ~32 amp (2000Watts), this is true
but when the ESS starting dicharging the battery (makes no sense what is soc at that moment) its only dicharging with ~12 amps (600 watts), while it must be possible to discharge with around 2000 Watts.
Multiplus is only connected to ac in, nothing connected to ac out (also switched off in the software) no limitations are set, or are far above what the multiplus is actualy delivering.
Ac input limit is 25 Amp, power assist is off, furthermore the standard settings from VeConfig, multiplus is connected to L1, system is 3 phase system.
what can cause this? i look already many times in the settings, but cannot find anything
