Battery is not included and must be supplied by the user. Solar controller automatically detects 12V or 24V battery systems; confirm battery type before connecting. Inverter accepts 12V DC input and provides selectable 110V or 220V AC output depending on model chosen. Practical applications Camping and outdoor recreation: charge phones, power lights, run small appliances, and charge a leisure battery while off grid. Emergency backup power: run essential electronics and lighting during short power outages when combined with a suitable battery. Mobile use in RVs or boats: convert vehicle battery power to AC for onboard appliances and provide solar charging support. Notes and recommendations The solar panel supplies limited charging current due to its 18W rating. For faster battery charging, combine with a larger solar array or shore charging as needed. Always follow the included manuals when connecting the solar panel, controller, inverter, and battery to prevent improper installation. Verify the inverter output selection matches the required AC voltage before connecting appliances.
