We have decided on a 3Kw inverter and work around showering times as we have been doing up to now.
Why is a normal electrical geyser not an option - The advantage is that the hot water is stored and can be used during loadshedding
If I was you I would not go less than 5kw inverter - the price difference is not big but it allows the odd spike .Also with ongoing water problems you could at least then run a small pump

Use a true hybrid that can feed back onto your house grid and have the geyser on the house grid with a timer - I heat the geyser between 11H00 and 14H00 to utilize the PV and a 150L geyser gets us 4 showers without having to heat outside of sun light hours - Geyser effectively cost me nothing - I have 2 geysers , one for the flat that presently has a short term tenant

I have a 5kw inverter , 5kwh battery and 5.1kw panels - generally use around 22Kwh per day but only have to purchase 5kwh per day.

I vary my usage depending on PV output with the pool pump .

You would not need to fit 5kw of panels but could start with 1 mppt with 3 Kw of panels and if needed at a later stage you could expand.

We have started numerous people off on 5Kw inverter and 3 Kw of panels - 2 of them have now expanded the systems to take extra panels and batteries to run the majority of time " off grid"
