Magic series solar controller is based on an advanced maximum power point tracking (MPPT) technology developed, dedicated to the solar system, the controller conversion efficiency up to 98%.This 30A mppt charge controller compatible with 12V and 24V systems,Also compatible with various Deep Cycle battery options: Sealed, Gel, Flooded, and Lithium (12.8V LFP).RS485 interface is currently unavailable.4-stage charging (MPPT, Boost, Float, and Equalization) and temperature compensation process has been optimized for long battery life and improved system performance.
Feature:
1. Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%
2. Full digital technology, high charge conversion efficiency up to 98%
3. LCD display design, read operating data and working condition easily.
4. Real-time energy statistics function.
5. 12/24V automatic recognition
6. Liquid,Gel,AGM and Lithium battery for selection
7. External temperature sensor, automatic temperature compensation
8. Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower down followed by the decrease of temperature, so as to control the controller’s temperature rise
9. Four stages charge way: MPPT, boost, equalization, float With current-limiting charging mode, when the power of solar panel is over-sized and charging current exceeds the rated current, the controller will lower the charging power, which enables the system to work under the rated charging current
10. Multiple load control modes: Always on, Dusk to Dawn, Evening, Manual
11. Support Android mobile phone APP,realize wireless monitoring function of solar controller.
12.Use high performance,ultra-low power consumption Bluetooth dedicated chip.Adopt Bluetooth 4.2 and BLE technology,communication distance up to 10m.
13.Real-time automatic fault alarm.
14.Charging and discharging quantities can be counted and displayed by item grouping and month.
15. Perfect EMC & thermal design
16. Full automatic electronic protect function
