They are designed to be left outside and are rated IP66 against dust and water - I've had mine out consistently for many months with no problems. Just learn from my mistakes and tie them down to the ground with sandbags or strings and hooks so they don't sail away in strong winds!
The Ecoflow 220w panel will NOT work with your Bluetti because it has an open-circuit voltage of 21.8V and the AC200P accepts a minimum of 35V to start working. The AC200P works with voltage up to a maximum of 150V for 700W of solar charging.
You will need to either purchase a second one of those panels and wire them in series or purchase different panels. I personally can vouch for the portable Renogy suitcase panels, I have both the 100W and 200W versions. IMO they're better than the Ecoflow 220w because they're sturdier and they use glass for better longevity and heat dissipation than plastic film protection on most portable panels. If you have a ~$600 budget for your panels I'd go with 2x 200W panels wired in series (which brings the open-circuit voltage to 2x21.8V = 43.6V) - you would not have any use for the bundled 20A solar controller that comes with the panels which is just for charging batteries directly and is not for power stations because the stations have their own MPPT charge controller.
