Product Description

Products Description

This solar charge controller utilizes the most advanced MPPT control algorithm, allowing the maximum power point of the PV array to be quickly tracked in any environment. This significantly improves solar energy utilization. It is ideal for communication base stations, home power supply systems, traffic lights, solar street lamps, and courtyard lighting systems.

Key Improvements & Comparison:

Visualization: Real-time display of solar panel voltage and PV input parameters.
Accuracy: Precise load mode timing with an error margin of only 1-2 seconds.
Heat Dissipation: Increased radiator gear spacing for natural cooling, improving charging efficiency.

✓ Advanced MPPT technology with tracking efficiency ≥ 99.5%

✓ LCD display for dynamic operation data and status

✓ Compatible with Seal, GEL, Flooded, and LiFePO4 batteries
