Reliable controller with built‑in protection and easy monitoring Key benefits Protects connected equipment and batteries from electrical faults: includes overvoltage, overcurrent and overtemperature protection to reduce risk of damage and downtime. Makes system status and performance easy to read: the LCD dynamically displays real‑time operating data and the device’s working status for quick diagnostics and monitoring. Lets you tailor operation to your needs: several controller parameters can be edited, set and saved by the user to match the behavior of your system. Precise night-to-day control with flexible timing: the light-and-time delay mode provides a 10‑minute delay after night detection before discharge begins, and supports programmable countdowns up to 23:59 to stop discharge automatically. Main functions and features Protections: overvoltage protection, overcurrent protection, and overtemperature protection safeguard both the controller and connected loads. Display: LCD shows dynamic operational parameters and current working status so you can confirm behavior at a glance. User configuration: a subset of controller parameters is user‑adjustable and storable, letting you adapt settings without reprogramming the unit elsewhere. Light-and-time delay control: when night is detected the controller waits 10 minutes then starts discharge and initiates the countdown; when the timer reaches zero the discharge stops. Maximum delay/time setting is 23:59. Practical applications Solar lighting systems: automatic night detection and programmable discharge timing make it suitable for controlling battery discharge and lighting schedules. Off‑grid battery systems: protects batteries from electrical faults while allowing user adjustments for runtime and behavior. Timed load control: use where loads must be automatically disconnected after a set period or controlled precisely during night operation. Why choose this controller Clear, actionable information on the LCD reduces troubleshooting time. Built‑in safeguards help extend component life and improve reliability. User‑adjustable parameters and a flexible night/time control mode provide practical adaptability for a range of installations. Note: All listed features reflect the controller’s functions as provided: overvoltage protection, overcurrent protection, overtemperature protection, LCD dynamic display of operating data and status, user-changeable/savable parameters, and the light-and-time delay mode with a 10‑minute night delay and maximum timer setting of 23:59.
