No batteries required

When the sun shines, it can use cells solar panels to provide all the necessary energy. power for the system, and there is a surplus. Charge the battery after charging, a protection circuit automatically protects the battery from overcharging. 2. Sunlight simply powers the system. 3. Sunlight is insufficient.
