Compact 30A solar charge controller designed for reliable PWM charging and straightforward system monitoring. Built from ABS for durable installation, it supports 12V and 24V systems and provides a USB output for small device charging. Key benefits Stable battery management: 3stage PWM charging improves charge efficiency and helps extend battery life through controlled bulk, absorption, and float phases. Clear monitoring and simple setup: LCD display shows operating data and status in real time. Intuitive buttons make configuration and mode selection easy. Low standby drain: Selfconsumption is only 10mA, preserving battery capacity when loads are idle. Safe operation: MOSFETs reduce heat generation and provide reverse current protection. Builtin protections include short circuit, open circuit, reverse connection, and overload protection. Broad compatibility: Works with 12V and 24V battery systems and automatically manages panel and battery operation using an industrial microcontroller. Convenient USB output: 5V 2.4A maximum USB port for charging phones, lights, or other small devices. Technical specifications Style: 30A Item type: Solar controller Material: ABS Rated voltage: 12V / 24V autoselect USB output: 5V 2.4A (maximum) Selfconsumption: 10mA Charging method: PWM (threestage) Operating temperature: 20 C to +55 C Package contents 1 x Solar Controller 1 x User Manual Installation and usage notes The controller may become hot during operation. Install it on a well ventilated surface and allow airflow around the enclosure. Ensure correct polarity when connecting panels and batteries to avoid reverse connection issues. Suitable for systems where PWM charging is appropriate. Check battery type compatibility in the user manual before use. Typical applications RV and camper battery systems for managing roof solar panels and household batteries. Offgrid cabins and small cottages for lighting, battery charging, and lowvoltage loads. Marine and boat systems to maintain auxiliary batteries and power small devices while at anchor or underway. This controller provides straightforward PWM charging, essential protections, and convenient monitoring for small to medium 12V or 24V solar setups.
