My customer has a 1.5kW system installed with a third party inverter brand. If he wants to upgrade the system with a Fronius Primo 5 kW inverter in addition to the existing system, where the DNSP requires 5kW export limit, can this be done by using a Fron

Yes, if your export limit is equal to or greater than the other inverter’s output capacity this can be done. Please note: The Fronius Smart Meter will not control the power output of the third-party inverter. For example: If the third-party inverter is 1.5 kW and Fronius inverter is 5 kW and there is only 5 kW allowed to export, then the export limitation value that can be set on the Fronius inverter is 5 kW.
