EPIP30 series intelligent controller is a product specially designed for solar photovoltaic power supply. It has the characteristics of battery capacity can be selected by users, light touch buttons, simple setting operation, system working voltage (12/24V) automatic identification, charging and discharging control, temperature compensation, direct charging, boosting, floating automatic charging mode, four load control modes: manual, pure photocontrol, photocontrol + timing, timing, TVS lightning protection, has overcharge, over discharge, electronic short circuit, overload protection and unique reverse connection protection, adopts large screen LCD liquid crystal specially designed for solar power supply, LCD displays all system status system parameters in intuitive digital and graphic form, and accurate clock display
This manual introduces the EPIP30 series solar controller, highlighting its selectable battery capacity, touch‑key operation, automatic 12 V/24 V detection, multiple charging modes (PWM or ON/OFF) and four load‑control options (manual, light‑control, light‑control + timer, timer). It also describes the LCD display that shows system status, voltage, current, temperature and energy data.
Installation instructions cover wiring order, cable sizing, grounding and mounting clearance. The operation section details key functions (K1‑K4), parameter adjustment, time setting, light‑control testing and protection features such as over‑charge, over‑discharge, short‑circuit and TVS lightning protection. A parameter table lists electrical specifications for the 20 A and 30 A variants. This manual is written in Chinese.
