MPPT AC/DC Hybrid Controller MEH160/200

Description

1. With MPPT technology, the tracking efficiency is up to 99.5% and the charge conversion efficiency is up to 96%.

2. Features a DC detection function. If DC is available, the system will automatically switch to DC power supply when the battery voltage falls to the DC switching point; if DC power supply powers off, the system will shut off output when reaching the over-discharge point after continuous discharge.

3. Lead-acid battery and lithium battery are available; operating parameters can be set by remote control.

4. Low sleep current for long-distance transportation and storage.

5. Temperature compensation function and multi-stage constant voltage charging for lead-acid battery.

6. Load power and time control.

7. Intelligent power mode: The load power can automatically adjust according to the battery level.

8. High-precision digital step-up voltage and constant current control algorithm: ensure high efficiency and high constant current accuracy.

9. Infrared remote control: allow for parameters setting and status checking.

10. Provide overcharge, over-discharge and overload protectionshort-circuit and reverse-connection protection.

11. With metal outer shell and IP67 waterproof rating, the product can function well in various tough situations.
