20A Solar PV Charge Controller with LCD Display, Builtin Timer and USB Port 12V 24V Overview A compact, easytouse solar charge regulator designed for small offgrid systems. Provides controlled charging for 12V or 24V battery banks, a clear LCD for system status and settings, a programmable timer for load control, and a USB port for charging small devices. Key benefits Reliable battery management: Regulates charging to reduce overcharge and deep discharge, helping batteries maintain usable capacity and longer service life. Simple monitoring and setup: The builtin LCD displays system status and settings so you can check voltage, charging activity, and timer configuration at a glance. Flexible power options: Supports both 12V and 24V systems and delivers up to 20A charging current to match a variety of small solar installations. Load scheduling with builtin timer: Turn lights and other DC loads on and off automatically to save energy and match usage patterns. Onthego device charging: Integrated USB port provides convenient charging for phones, tablets and USBpowered accessories directly from the battery system. Main features Maximum charging current: 20A System compatibility: 12V and 24V battery systems Display: LCD for realtime status and parameter settings Timer: Builtin timer for programmable load control USB port: For charging small electronic devices Connections: Terminals for photovoltaic panel input, battery, and DC load output User controls: Accessible buttons for mode selection and timer programming Performance and usability Supports common smallscale solar setups where steady charging and scheduled loads are needed. Straightforward wiring and a readable LCD make installation and daily use practical for homeowners and installers. Compact form factor fits small junction boxes or control panels for neat system integration. Typical applications Offgrid cabin lighting and battery charging: Manage panel input to keep a 12V or 24V battery bank charged and schedule interior or exterior lighting with the builtin timer. RV and marine systems: Provide regulated charging for vehicle or boat batteries while offering a USB port for charging mobile devices. Small solar garden or pathway lighting: Automate evening lighting runs and reduce battery drain by scheduling load times. What it solves Eliminates the need for manual switching by automating load schedules. Prevents improper charging that can shorten battery life by maintaining controlled charge cycles. Provides a convenient, centralized interface for monitoring and adjusting system behavior. Compatibility and installation notes Designed for use with small photovoltaic panels and battery banks rated for 12V or 24V systems with a maximum controller current of 20A. Suitable for DC loads compatible with the system voltage and within the controller load rating. Install in a dry, ventilated location and follow standard electrical practices for wiring and fusing. This controller is a practical choice for small solar projects that require dependable charge regulation, basic load scheduling, and convenient USB charging without complex setup.
