solar controller SRNE MPPT SR-ML2420 (MPPT inverter) 20A

MPPT Charge Controller with built-in MPPT and display. The MPPT monitoring efficiency is 99.9%. Supports gel, closed, maintenance and lithium batteries.

Product description:

1. Duplicate technology for tracking "peak" values ​​eg shadowing or partial damage

photovoltaic module. The current and voltage curves have several peaks. Solar regulator

charging can even more accurately monitor the point of maximum power.

2. Built-in algorithm for maximum performance monitoring. This greatly improves efficiency

energy use from photovoltaic systems, charging efficiency is 15% ~ 20% higher than u

traditional solar PWM chargers.

3. Combination of multiple tracking algorithms that can track the optimum working point

curves of current (I) and voltage (V) exactly in a very short period of time.

4. MPPT tracking efficiency is 99.9%.

5. Advanced digital technology, efficiency of conversion between input and output up to 98%.

6. Support for gel, hermetically sealed, open, lithium and other battery types during charging.

7. Online charging limiter. When the power of the solar panel is too high and the charging current is greater than

rated current, the charging controller automatically reduces the charging power to the rated charging current.

8. The "LOAD" output is conceived for capacitive loads with a high starting start current.

9. Support for automatic battery voltage detection.

10. LED fault indicator, acoustic signal and LCD display. This will help identify the user

system failure.

11. Backup data backup for up to 5 years.

12. LCD display, display allows users to view the operating data and device status data

and modify parameters at the same time.

13. Support of standard Modbus communication protocol for different requirements.

14. Integrated overheating protection. If the temperature exceeds the set value, the charging current

decreases linearly with temperature. Therefore, it slows down the temperature rise of the controller and prevents damage to the charger

controller.

15. External battery voltage measurement. This feature prevents incorrect battery voltage measurement over

charging cable lead. This ensures greater accuracy in the control of charging parameters.

16. Temperature compensation, charging, and discharge parameters are automatically regulated, thus

extends battery life.

17. Integrated TVS protection for potential voltage increase (indirect lightning strike)
