40A Smart Solar Charge Controller with Load Management

Overview

The 40A Smart Solar Charge Controller is designed to optimize solar charging and load control for 12V and 24V systems. This versatile device automatically adjusts charging profiles based on battery types, facilitates various load modes for efficient lighting and scheduling, presents real-time updates on a dot-matrix LCD, and incorporates industrial-grade safety features to ensure dependable operation with minimal maintenance.

Benefits

• Enhances battery longevity by utilizing suitable charging profiles and three-stage PWM charging technology.
• Minimizes maintenance needs and reduces the risk of battery failure through prevention of sulfation on lead-acid batteries.
• Streamlines setup process with automatic detection for 12V or 24V systems, plus a manual selection option if necessary.
• Simplifies lighting and load management with five operational modes and timer functions for automated control.
• Provides immediate feedback on system status through an LCD interface and memory-backed setting adjustments.
• Boosts system reliability, even in tough environments, thanks to advanced surge and reverse-polarity protections.

Features

• Automatic voltage detection that recognizes 12V or 24V systems with a manual setup option available.
• Compatible with multiple battery types, featuring optimized charging profiles for Sealed, GEL, Flooded, and Lithium batteries.
• Employs advanced 3-stage PWM charging with Boost, Float, and Equalization functions to prevent lead-acid battery sulfation (Equalization not available for GEL or Lithium).
• Temperature compensation for automatic voltage adjustment based on ambient conditions, excluding Lithium batteries.
• Offers five load modes: Light Control, Light Control with Timer, Manual, Debug, and Normal On, for flexible use.
• Fully equipped with comprehensive protections against overcharging, deep discharge, overload, short circuits, and reverse polarity.
• Industrial-grade lightning and surge protection for enhanced durability in outdoor and unstable power conditions.
• User-friendly dot-matrix LCD for real-time system monitoring, complemented by dual-button control for easy parameter adjustments.
• Sturdy enclosure designed to operate in a wide temperature range, featuring an IP30 protection rating.
