40A MPPT Solar Controller

Professional 40A MPPT Solar Controller - Heavy-Duty 48V/36V/24V/12V Battery Management System

• Precision Voltage Protection: Automatically guards your system with 42V-64V range protection for 48V batteries and 10.5V-16V for 12V setups.
• Intelligent Load Control: Features a 10-minute delayed start/stop for Light Control Mode to prevent false triggers during dawn or dusk.
• Optimized Battery Health: Includes specific charging cut-offs (e.g., 59.2V for 48V systems) to prevent hazardous overcharging and extend battery life.
• Real-Time Thermal Monitoring: High-precision internal sensors display controller temperature with an automatic 75°C fault protection trigger.
• Customized Discharge Scheduling: Built-in Timing Control Mode allows users to set specific 24-hour start/stop schedules for connected DC loads.

Intelligent Low-Voltage Recovery Logic

Designed to safeguard battery health, this MPPT Solar Controller automatically cuts discharge at 42.0V (for 48V systems) and features a 5-second manual override to resume power if urgent output is required.

Dual-Delay Light Sensing Technology

To prevent false triggers from temporary light sources, the MPPT Solar Controller implements a smart 10-minute delay for both starting and stopping the load in Light Control Mode.

Dynamic Battery Capacity Tracking

The advanced LCD interface provides a real-time percentage display of battery capacity and a dynamic 4-bar charging icon, allowing you to monitor the energy storage status of your MPPT Solar Controller at a glance.

Precision Safety Cut-off Parameters

The system ensures high-voltage safety by stopping discharge immediately if the battery exceeds 64.0V (48V system) or 16.0V (12V system), automatically resuming only when the voltage returns to a stable range.
