Why is my Conext SW Inverter/Charger faulting with F2 (AC output Over voltage)?

Conext SW Inverter/Charger is faulting with F2

Problem: Conext SW is faulting with F2(AC Output Over Voltage)
Solution:  Check the firmware and make sure it is 3.0.
The trip limits on the 3.0 were increased so it is most likely the CSW has older firmware.
