Battery protection: protects the connected battery from overdischarge, overvoltage, and lowvoltage conditions, and provides overload protection for load discharge current. This helps extend battery life and prevent damage. Time control mode: enables manual setting of load on time and load off time, allowing precise scheduling of when the connected device powers on and off. Light control with time delay: provides a light control option with a configurable ontime delay. When enabled, you can set how long the load remains on after the control is activated. Overheating protection: monitors the overall device temperature and shuts down or limits output to prevent overheating and ensure safe operation. Solar panel and battery reverse connection protection: guards against reverse polarity connections between the solar panel and battery to prevent damage. Function and compatibility: designed for solar panel and battery systems, offering essential protection and programmable control for reliable, unattended operation. Suitable for integration into small to medium offgrid setups with standard solar and battery configurations. Performance and reliability: built to respond quickly to fault conditions, maintain safe operating temperatures, and provide predictable timing for load control and lighting applications. Use scenarios: 1) Outdoor solar lighting: install with a garden light or wallmounted light to automatically switch on/off according to a userset schedule, with protection to guard the battery and wiring. 2) Offgrid monitoring or sensing: power a remote sensor or small camera with a programmable on/off cycle and protection from voltage or temperature issues. 3) Small solar irrigation or pump control: run a pump or valve on a timed schedule, while protecting the battery and solar wiring from reverse connections and overloads.
