SR-E series solar intelligent charging controller has five load working modes, advanced AC complementary switching function, scientific battery management mode, high precision temperature compensation, charging circuit adopts dual MOS series control circuit, LED intuitively displays the status of solar cell, battery, load and AC, and digital tube displays the adjustment parameters.
The SR‑E series solar charge controller is designed for solar DC power systems, street‑light systems and small solar stations. It uses a microprocessor‑based control algorithm, offers five load‑working modes, and includes advanced commercial‑power switching, battery management, and multiple protections.
The document provides detailed installation steps, wiring diagrams, parameter settings, and a FAQ section that helps users diagnose common indicator‑light issues and protect the system from over‑charge, over‑discharge, overload, short‑circuit and reverse‑polarity conditions. This manual is written in Chinese.

Check the photocell wiring and make sure the connection is correct and reliable.
The battery is over‑discharged; after it is recharged the controller will automatically resume operation.
The load indicator flashes slowly; reduce the connected load and press the key for a longer time to reset.
