Can I operate an air conditioner with a balcony power plant?

So from my point of view the answer is: It depends.

In the transition period, so February/March and September/October, it should work depending on the positioning of the panels. At least a small 500W fan heater can already do something regarding moisture-heat regulation (if you ventilate accordingly). We operate it ourselves like this in our house with a Home Assistant that pushes the excess energy from the BK into the fan heater. But as Jesse writes, some preliminary work is necessary, although it is not rocket science.

However, I am not aware of an air conditioner in this power range, more power is probably necessary. But with a fan heater, you could certainly achieve something. (Disclaimer: In winter, the energy is not enough, no matter where the modules are located! And in summer you have the electricity but not the necessity)

(PS: Since you write "ohne Netzstrom", electricity is of course still necessary to operate the inverter. Unless you have installed an off-grid system, but I assume you are aware of that)

I would probably do it a little differently. Especially because of the simple regulation. A balcony power plant with 2000W (buy 4 photovoltaic panels) with a 2KW storage. Run them normally. The air conditioning should be WLAN-enabled and controllable via an app. Set the air conditioning to frost protection, e.g. 5 degrees Celsius. If you know you’re going to the vacation home, then remotely adjust to your desired temperature in time. This makes it simple, safe, and you use photovoltaic electricity. Also at night, if surplus is available. Pure use of photovoltaic electricity makes it much more complicated and practically impossible in the winter months due to lack of solar energy.

Thank you very much for all the answers. Because of this, I understood a lot and was able to get an idea of what is necessary. --> At least one storage with info about the charge level (remote) and a remotely controllable air conditioner. Thank you very much!

From a purely economic perspective, what you have planned is quite nonsense. When is this investment in a weekend house supposed to pay off?
