- Functionality: The controller uses Pulse-Width Modulation (PWM) technology to regulate the charging process. It periodically switches the solar panel’s output on and off to maintain a consistent voltage level for charging the battery.
- Current Capacity: The 30A rating indicates that the controller can handle a maximum charging current of 30 amps. This makes it suitable for systems with moderate power requirements.
- Voltage Compatibility: The controller is designed to work with 12V or 24V battery systems, automatically detecting the system voltage.
- Protection Features: It incorporates various protection features such as short-circuit protection, reverse polarity protection, overcharge protection, and overdischarge protection to safeguard the battery and the solar power system.
- Display and Controls: Some models may include an LCD display that provides information about the charging status, battery voltage, and other relevant parameters. They may also have buttons or knobs for configuration and adjustment.
- Additional Features: Depending on the model, a 30A PWM solar charger controller may offer additional features such as USB ports for charging electronic devices directly from the controller, temperature compensation, and communication interfaces for monitoring and control.
