The Multi RS is the simplest to use and set up.

Use 2x us5000 pylons minimum.

Panel choice largely depends on local suppliers and configuration for the mppt chosen.

The manual for the RS and the online mppt calculator will help with panel configuration.

Autonomy is a different question though. Usually it means that there has been a power audit and you know what the system needs to produce and length of autonomy is determined. For example 24 hours 36hours? If you use more than 10kwh of power at night (not referring to the dark but when your solar stops producing enough to cover load and then start producing enough to cover loads and charge the battery again) then 2x us5000s is not enough.

Relying completely on solar (and battery storage) may be an expensive solution. You'd need a battery bank to cover your longest outage and probably more solar energy production so you can catch up before the next storm.

Even a small generator could help through long periods without solar. Your battery bank can handle peak consumption needs so the generator only needs to be large enough for your average consumption.

As Alexandra says, you need to do a power and energy analysis: peak power consumption (in watts) will tell you how big in inverter you need; energy is your daily consumption in watt-hours will indicate how much battery storage you will need. It's useful to calculate energy consumption separately for daylight and night time (no sun) portions of the day so you can get an idea of battery state of charge during a typical day.
