Overload protection on Inverter output

The idea is to have something similar to a PV fuse as its fast blowing, this would basically limit the inverters output and should this be exceeded, the fuse would blow before the inverter overloads. We have looked into the idea of using normal breakers but this wouldn''t work as even a 20A breaker can surge up to 80A for 10 seconds before it trips.
