SR-LP series solar intelligent charging controller is a intelligent dimming solar street light controller, which has five load operation modes, scientific battery management mode, parameter setting with power-off preservation function, charging circuit using dual MOS series control circuit, LED intuitive display of solar cell, battery and load status, etc.
The SR-LP series solar intelligent charge controller is designed for solar DC LED lighting systems and other dimming applications. It uses a micro‑processor and dedicated control algorithms to provide five load operation modes, PWM digital dimming, and advanced battery management with over‑charge, over‑discharge, overload and reverse‑polarity protection.
The manual describes the controller's main features, system description, installation steps, panel layout, operation instructions, parameter settings and a troubleshooting guide. It also lists detailed electrical specifications such as rated currents, voltage drops, temperature compensation and protection thresholds. This manual is written in Chinese.
