Is it normal to have a 235 volt inverter?
Yes, this is normal. NB: In your voltage definitions, a current of 11A * Voltage of 235V means that you have an inverter with PNom = 11*235 = 2.58 kW (per MPPT input). This doesn't correspond to you previous posts where you had a voltage limitation of 235V for an inverter of 5 kW, i.e. a current of 21.28 A
What is a 235 Volt in a 5 kW inverter?

Can a 230 volt inverter go into backup/up mode?
If the inverter is set to SA grid code, it will only tolerate voltages of 230V±10%, which means that it would have disconnected and go into backup/ups mode when the grid voltage dropped to "196.5 V". Yeah I assumed there was some fine print I'm missing, thanks for clearing that up It is more about the voltage than the frequency
How much voltage should a 230 volt inverter be?
The voltage is not required to be exactly 230 V. There is a tolerance. 5% (if that's what it is), gives you 11.5V either way. Anyway, I have set my inverter for our safety code, and I leave it to disconnect when it sees fit.
What if a 50Hz inverter is not set to SA grid code?
In that inverter, 50Hz Default, AKA "Wharehouse" setting is a test mode. If it is not set to SA grid code, it is not compliant. If the inverter is set to SA grid code, it will only tolerate voltages of 230V±10%, which means that it would have disconnected and go into backup/ups mode when the grid voltage dropped to "196.5 V".
Should a solar inverter be prioritised over a grid?
If it is one of the common inverters that get used to feed power to the house, there should surely be some type of setting to prioritise solar over grid. The source is not the problem. The problem is that the inverter synchs the voltage to the incoming Eskom feed - even if I am running fully on solar
