It appears the pump has a 1.1 kW rating, so you need a 5 kW inverter to start it (or one that can surge to 5 kW for a few seconds.)
That's assuming the pump has an induction motor. If it is 3-phase internally with an inverter drive (powered by single phase externally), then no starting surge.
It appears this pump can work with a pressure control unit to vary speed and water volume, suggesting does contain VFD and may be very easy to start with a small inverter:
I've had some experience with VFD and transformerless inverter, which wasn't happy with the electrical load it had to feed. You are probably better off with a low frequency transformer-type inverter. Although, I see references to power factor correction which could alleviate the issue.
How long will it have to run per day, to lift the amount of water you want? Turn that into kWh and divide by 4 to estimate how many kW of PV panels are needed to power it. Same kWh math to get panels for the rest of your loads.
Batteries - you need something to deliver the starting surge. Beyond that, I don't believe in batteries; run your loads during the day. But if you need to run something at night, figure out how many kW and multiply by 2 to size your battery (lead-acid). If you want to run a freezer during multiple overcast days, decide how long it will be dark, also determine the freezer's power consumption (much less than label, go by annual energy estimates for the model. Typically averages out to 50W or 100W around the clock.) But install more panels than that - they're inexpensive, and amount of sun varies.
And yes, we do make fun of language. After all, ours is a bastard language made up of all the others.
The French can speak English, they just choose not to.
We Americans can't speak French.
But I always say, "The dollar speaks English"
