Charge for AGM, Liquid, GEL and Lithium Battery

Waterproof: Suitable for indoor or outdoor use
7 Battery Types: Lithium-ion, LiFePO4, LTO, Gel, AGM, Flooded, and Calcium
Bluetooth: Support mobile phone APP,wireless monitoring


Electrical Protection

- Spark-free Protection
- Reverse polarity solar and battery connection
- Reverse current from battery to solar panel protection at night
- Over temperature protection with derating charging current
- Transient overvoltage protecrion at solar input and battery output protects against surge voltage      



1. Waterproof design, suitable for indoor or outdoor use
2. Battery Type Compatible Lithium-ion, LiFePO4, LTO, Gel, AGM, WET, and Calcium
3. Support mobile phone APP, realize wireless monitoring function of solar controller
4. LCD display design, read operating data and working condition easily.
5. Adopt Bluetooth 4.2 and BLE technology, communication distance up to 10m
6. Real-time automatic fault alarm
7.  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
8. Four stages charge way: Fast, boost, equalization, float
9. With current-limiting charging mode, when the power of solar panel is over-sized and charging current exceeds the rated current( ≤60% of rated current), the controller will lower the charging power, which enables the system to work under the rated charging current
10. Perfect EMC & thermal design
