Solar controller manual, introduces the function characteristics, installation and use of solar controller.
The manual introduces a solar controller designed for off‑grid applications, describing its automatic charge‑discharge control, battery protection features, and PWM charging circuit. It explains the system voltage auto‑recognition, dual‑MCU design, and LCD interface for easy monitoring.
Installation steps cover wiring preparation, battery connection, solar panel hookup, and load connection, followed by detailed instructions on the LCD menu, LED indicators, fault codes, and backlight control. Technical specifications such as supported voltages, currents, protection thresholds, and environmental ratings are listed at the end. This manual is written in Chinese.

A slow‑flashing LED shows the battery is in float‑charge state.
The backlight turns off automatically after 60 seconds of inactivity.
Press the SET key on the battery‑type selection page to choose between sealed‑lead and gel batteries.
It limits overload to 1.25 × rated current for 30 s and 1.5 × rated current for 10 s, with higher thresholds for short‑circuit protection.
