MPPT Solar Charge Controller

System Voltage: DC12V/24V/36V/48V Automatic Recognition

Rated Current: 30A 

Maximum PV(voc) Voltage: 100V

 

 

ESmart2 series is the second generation of eSmart mppt controller, based on eSmart series mppt controller, we update the display with LCD, control method, connect way, internal structure etc. It features an efficient MPPT control algorithm to track the maximum power point of the PV array. Greatly improve the utilization of solar panel. Its intelligent LCD and upper PC display, mostly convenient for customers to check, records and parameter setting. It widely used in off-grid solar system, communication base station solar system, household solar systems, street light solar systems, field monitoring and other fields etc.

 

 

1.High efficiency MPPT control algorithm, MPPT efficiency ≥99.5%, whole Machine conversion efficiency upto 98%;

2.12V/24V/48V system Automatic Recognition,users can use it in different system conveniently.

3.Maximum PV input voltage: 100VDC

4.Charge mode: three stages (fast charge, constant charge, floating charge). It prolongs service life of the batteries.

5.Discharge mode: ON/OFF mode, PV voltage control mode.

6.Recommended battery types: Sealed lead acid, Vented, Gel, NiCd battery. Other types of the batteries can also be defined.

7.Most information could be provide by LCD like: model No., PV input voltage, battery type, battery voltage, charging current, charging power, working status and so on. 

8.RS232 communication.

9.CE, RoHS, FCC certifications approved.

10.2 years warranty.
