1. 서론
The POWERTECH MP3752 is an intelligent and lightweight solar charge controller designed to manage the power flow from your solar panels to your battery bank. Utilizing Pulse Width Modulation (PWM) technology, it ensures efficient and safe battery charging. This controller offers a set-and-forget operation, providing maximum charge into your batteries without constant monitoring. It integrates essential safety features such as overload, short-circuit, over-discharge, and reverse-polarity protection. Additionally, a convenient USB port on the front panel allows for up to 1.2A charging, useful for mobile devices during power outages. The unit supports various battery types including sealed lead-acid, Gel, and flooded cells, and automatically selects the optimal charging mode (bulk, equalise, float).

7. 사용 설명서
7.1. Automatic System Voltag전자 인식
The controller automatically detects whether the connected battery bank is 12V or 24V upon initial connection. Ensure the battery is connected first for proper voltag전자 탐지.
7.2. 충전 모드
The MP3752 employs intelligent PWM charging, automatically cycling through different stages to optimize battery health and lifespan:
- 대량 청구 : 배터리를 빠르게 약 80%까지 충전하기 위해 최대 전류를 공급합니다.
- Equalise Charge: 주기적으로 더 높은 볼륨을 적용합니다.tage to equalize the charge among battery cells, preventing sulfation and extending battery life (for flooded batteries).
- 플로트 충전 : 소량의 일정한 전압을 공급하여 배터리를 항상 완충 상태로 유지합니다.tag즉, 자가방출을 보상하는 것입니다.
7.3. 부하 제어
The load output is controlled by the controller to prevent over-discharge of the battery. When the battery voltage는 Low Vol 아래로 떨어집니다.tage Disconnect (LVD) threshold, the load output will be automatically disconnected. It will reconnect once the battery has recharged to the Low Voltage Reconnect (LVR) threshold.
Press the power button on the controller to manually turn the load output ON or OFF.
7.4. USB 충전 포트
The 5V, 1.2A USB port can be used to charge small electronic devices like smartphones or tablets. This port is active as long as the battery has sufficient charge.
