[Precision Monitoring]The solar controller adopts an industrial-grade main chip, 16AD sampling accuracy, temperature, and accurate real-time discharge current display, and the power generation is clear at a glance. [Fast Charging Speed]MPPT solar controller has high charging efficiency, autofocus MPPT tracking loading, high charging efficiency, non-stop detection and charging, and bidirectional focus tracking. [Multiple Intelligent Protection]The charging controller has multiple intelligent protection functions, bu-ilt-in overcurrent protection, short circuit protection, reverse polarity protection, open circuit protection, automatic recovery, [HighTracking Efficiency]The solar fast charge controller adopts innovative MPPT technology, the tracking efficiency is as high as 99%, compared with ordinary controllers, thiscan increase the efficiency by 10%-30%. 1. Always keep the battery at the charging voltage. 2. Prevent the battery from overcharging. 3. Prevent the battery from discharging too much. 4. Prevent the battery from charging backward on the solar panel at night. 5. Battery reverse polarity protection 6. Reverse Polarity Protection for Solar Panels 7. When the battery voltage is low, the controller will automatically reduce the system load. If the battery voltage returns to normal, charging restarts. 8. The controller automatically compensates for temperature, and the charging voltage is a function of ambient temperature changes.
