Yes, I am very satisfied with the WS200SF SunFolder+ (200 W, 6.80 kg). If your ECO Flow Pro has a direct input for a solar panel, no additional charge controller is necessary. This should be stated in the operating instructions of the ECO Flow Pro. Attention with 200 watts of solar power, only a maximum of 2 kWh of electricity can be stored on a summer day under ideal conditions. That is neither enough for heating nor for cooking!
