- Renhed: Keep the solar panel clean and free from dirt, dust, or debris to maximize its efficiency in maintaining battery charge. Use a soft, damp klud til rengøring.
- Miljøbeskyttelse: While the unit is IP65 rated, prolonged exposure to extreme weather conditions, especially heavy rainstorms, should be minimized. Consider additional protection if the trailer is stored outdoors for extended periods in harsh climates.
