This manual covers installation, operation, and maintenance of the Apollo Battery Guard 12V solar charger. It includes step-by-step setup instructions, troubleshooting tips, and safety warnings. The system uses a solar film to charge 12V batteries via an OBD port or direct alligator connections. Charging time varies based on sunlight conditions. The controller protects against overcharging and includes safety features like short-circuit and reverse polarity protection.
The included film measures 82cm x 31.5cm and generates up to 21W. The charger consumes 0.7–2.5mA during the day and 0.24mA at night.
