This is a Maximum Power Point Tracking (MPPT) solar charge and discharge controller with self-cooling, automatic system recognition, wide PV voltage input range, capability to charge various types of batteries, intelligent discharge control, RS485 communication, and other advantages. It is currently the most advanced MPPT solar charge and discharge controller.
Product Features:
1. Efficient MPPT controller algorithm with MPPT efficiency no less than 99.5% and overall conversion efficiency up to 98%.
2. Charging modes: three-stage charging (constant current, constant voltage, float charge) effectively prolong battery life.
3. LOAD modes include always-on/always-off, light control mode, dual time period control mode, and light control with fixed time control mode.
4. Automatic battery system voltage recognition.
5. Users can choose to charge three common types of batteries (sealed lead-acid, gel lead-acid, open lead-acid) and can customize parameters for other types of batteries.
6. Equipped with current-limited charging function: when the user’s solar panel power is too high, the controller automatically maintains charging power, ensuring charging current does not exceed the rated value.
7. Supports parallel connection of multiple units for system power expansion.
8. High-definition LCD display for viewing device operation data and working status, and supports modification of controller display parameters.
9. RS485 communication, with available communication protocols for easy system integration and secondary development.
10. Supports upper computer software monitoring and WIFI module expansion for app cloud monitoring.
11. Product certified with CE, ROHS, FCC; can assist customers in obtaining various certifications.
12. Standard warranty period of 2 years, with extended warranty options from 3 to 10 years.
