This solar charge controller provides clear, reliable control and monitoring for small to medium off grid solar systems. It combines a large LCD display, flexible control options, and robust protection to make system setup and operation easier and safer. Key benefits Clear monitoring: Largescreen LCD shows charging current, discharging current, accumulated power generation and discharge, and temperature so you can track system status at a glance. Safer operation: Builtin protection against overcurrent, shortcircuit, opencircuit, and reverse connection protects the system and recovers automatically without damaging the controller. More efficient charging: Complete 3stage charging management improves battery life and charging efficiency while simplifying charging control. Flexible control and tuning: Light control with delay, plus adjustable charging and discharging parameters, lets you tailor operation to your load and battery type. Stable performance: Industrialgrade main control chip, antibackflow circuit, and ultralow heat generation increase conversion efficiency and longterm reliability. Key features Large LCD display for realtime monitoring of currents, accumulated energy, and temperature. Display and query of accumulated power generation and discharge totals for easy energy tracking. Temperature display to help manage battery and controller operating conditions. Light control plus delay control for automated on and off behavior based on illumination and timing. Adjustable charging and discharging parameters for compatibility with different battery types and application needs. Complete 3stage charging management for bulk, absorption, and float charging control. Protections against overcurrent, shortcircuit, opencircuit, and reverse connection. All protections are selfrecovering and do not damage the controller. Industrialgrade main control chip and antibackflow circuit for improved conversion rates and reduced heat generation. Compatibility and performance Designed for common offgrid solar setups including PV panels and battery banks. Adjustable parameters allow adaptation to various battery chemistries and system sizes. Compact, robust enclosure and reliable electronics suitable for residential, recreational, and light commercial use. Low thermal footprint helps maintain conversion efficiency and extends component life. Practical applications Offgrid cabin or tiny home: Manage battery charging from PV panels, track daily generation, and automate lighting with light and delay control. RV or camper solar system: Monitor charging and discharging currents, protect the battery from faults, and adjust charging parameters to match the battery. Remote lighting and outdoor installations: Use light control and delay functions to automate lighting while recording accumulated energy and protecting against wiring faults. This controller is intended for users who need accurate monitoring, flexible control, and strong fault protection in their solar charge management system.
