I don’t think there’s any other Modbus register of KACO available to set individual phase powers.
Actually we got into a confusion because we used peakshavigng asymmetric controller with kaco and it worked. Then I found that it just multiplies that power by 3.
Anyways, could you suggest some solution plz or we have to change the inverter?
Yes, this is in fact a workaround we use in production systems e.g. with asymmetric electric vehicle charging stations
I don’t know of any battery inverter that is able to have asymmetric set-points. That’s also due to the legislation here in Germany, that is unfortunately very restrictive with asymmetric power output of energy storage systems. We used to have this with an earlier product (FENECON Pro 9-12), but I don’t know of any current system with higher power.
