4. 제품 특징
- High-Efficiency Monocrystalline Core: Precision-engineered with premium monocrystalline cells, delivering 20%-25% photoelectric conversion efficiency (STC). This outperforms polycrystalline and amorphous counterparts in energy yield under equivalent conditions.
- Adaptive Battery Preservation: Features intelligent two-phase charging: rapid bulk charging for low-voltage batteries, transitioning seamlessly to micro-current trickle mode at near-full capacity. This neutralizes self-discharge while preventing overcharge degradation, ensuring optimal 12V battery maintenance.
- Universal Compatibility Ecosystem: Offers versatile connectivity via OBDII, cigarette lighter, alligator clips, and O-ring interfaces. Supports vehicles, marine crafts, outdoor electronics (cameras, pumps, electric fences), and seasonal equipment. Compatible with lead-acid, LiFePO4, AGM, GEL, lithium, and flooded batteries.
- Fail-Safe Charging Intelligence: Integrated smart controller enables autonomous charge cycling – halting at full capacity and reactivating upon voltage drop. Guarantees zero reverse current discharge for perpetual battery safeguarding.
- Sustainable Energy Autonomy: Solar-powered preservation ideal for infrequently used assets. Proactively combats parasitic drain from vehicle telematics/alarms, ensuring instant start readiness. Engineered for battery longevity, not deep-cycle recharge.

5. 설정 및 설치
Follow these steps to set up and install your FlexSolar 20W Solar Panel Battery Charger Maintainer:
- 태양광 패널을 펼치세요: Carefully unfold the solar panel to its full size.
- 최적의 햇빛을 위한 위치 선정: Position the solar panel to receive maximum direct sunlight. The solar panels achieve optimal charging power when they are positioned perpendicular to the rays of light, or at a 90-degree angle. Use the included suction cups to mount the panel on a windshield or sunroof, or use carabiners to hang it.
- Connect to Your Battery: Choose the appropriate connector for your battery type and vehicle. Ensure correct polarity (red to positive, black to negative).
- OBDII 커넥터: Plug the SAE to OBD-II connector into the solar panel's SAE port, then plug the OBD-II end into your vehicle's OBD-II port.
- Cigarette Lighter Connector: Plug the SAE to car charger connector into the solar panel's SAE port, then insert the car charger end into your vehicle's cigarette lighter socket.
- 악어 클립: Plug the SAE to alligator clip connector into the solar panel's SAE port. Connect the red alligator clip to the positive (+) terminal of your 12V battery and the black alligator clip to the negative (-) terminal.
- O링 단자: Plug the SAE to O-ring terminal connector into the solar panel's SAE port. Secure the red O-ring to the positive (+) terminal of your 12V battery and the black O-ring to the negative (-) terminal.
- 충전 확인: The integrated smart controller will automatically begin charging. Monitor the LED charging indicator on the controller to confirm charging status.

6. 사용 설명서
The FlexSolar 20W Solar Panel operates autonomously once connected to a 12V battery and exposed to sunlight. It is designed for continuous maintenance charging.
- 자동 충전: The built-in charge controller intelligently manages the charging process. It initiates rapid bulk charging when the battery voltage is low and transitions to a micro-current trickle mode as the battery approaches full capacity.
- 과충전 보호 : The smart controller prevents overcharging by halting the charge when the battery reaches full capacity and reactivating it if the voltag이드롭스.
- 역전류 보호: The controller ensures zero reverse current discharge, preventing the battery from draining back into the solar panel during periods of low light or darkness.
- LED 표시등: The LED indicator on the controller provides visual feedback on the charging status. Refer to the label on the controller for specific light indications (e.g., blue light for charging, red light for fully charged).
