e-Smart series MPPT solar charge controller is a smart solar controller with automatic recogtion function, smart charging and discharging function, three stages charging function to protect battery. It can increase 30%-60% efficiency than traditional PWM controller. It supports many kinds of batteries. It also have RS232 communication port to allow computer connection.


Currently, This series MPPT controller has 15A, 20A, 25A, 30A, 40A models. It can automatically recognize 12VDC, 24VDC, 48VDC battery system. The most important is this model MPPT controller is more economical than other model types, which can help you save more budget to get excellent peroformance product.



1. MPPT charging mode, peak efficiency up to 99%, saving 30%-60% solar panel than traditional PWM controller.

2. DC12V/24V/48V battery system automatic recognition, users can use it in different system conveniently.

3. Maximum PV input voltage up to DC100V.

4. Three stages charge: fast charge (MPPT), constant voltage charge, floating charge. It can protect batteries well.

5. Three options of discharge: on mode and off mode and PV voltage control mode.

6. Users can choose 4 kinds of commonly standard batteries ( Sealed lead acid, Vented, Gel, NiCd), Other kinds of batteries can be defined by users.

7. Digital tube can display battery voltage and charging current. The software can display various parameters such as model number, PV input voltage, battery type, battery voltage, changing current, charging powr, working condition.

8. RS232 communication, we can offer communication protocol also, It is convenient for user’s integaration management.

9. This controller can be paralleled infinitely.

10. CE and RoHS certifications are approved. We can help clients to approve other certifications if your quantity is larage.

11. 2 years warranty; 3-10 years extended technical service.
