[Precision Monitoring] This solar panel regulator uses an industrial-grade main chip with 16AD sampling accuracy. It provides accurate, real-time display of temperature and discharge current, making power generation clear at a glance. [Fast Charging Speed] The MPPT solar panel regulator boasts high charging efficiency with autofocus MPPT tracking. Enjoy continuous detection, charging, and bidirectional focus tracking. [Multiple Intelligent Protections] This charging regulator features multiple intelligent protection functions, including built-in overcurrent protection, short circuit protection, reverse polarity protection, open circuit protection, and automatic recovery. [High Tracking Efficiency] Utilizing innovative MPPT technology, this solar panel fast charging regulator achieves a tracking efficiency of up to 99%. Compared to ordinary regulators, this can increase efficiency by 10%-30%. 1. Always keep the battery at the charging voltage. 2. Prevent the battery from overcharging. 3. Prevent the battery from over-discharging. 4. Prevent the battery from reverse charging the solar panel at night. 5. Battery reverse polarity protection 6. Solar panel reverse polarity protection 7. When the battery voltage is low, the regulator will automatically reduce the system load. Charging will resume when the battery voltage returns to normal. 8. The regulator automatically compensates for temperature, and the charging voltage is a function of ambient temperature changes.
