Part two: About the controller

3 series 16 models MPPT SolarCharge Controller Series as below:

1. I-P-Smart1 Series 12V/24V/48V Automatic Recognition 40A ~ 60A 96V System 20A~30A

2 I-P-Smart2 Series 12V/24V/48VAutomatic Recognition 20A ~ 60A

3.I-P-eSmart Series12V/24V/48V AutomaticRecognition 15A ~ 40A

1. What is "Smart"?

Answer: Due to high cost of panels, lowconversion efficiency of ordinary PWM controller, I-Panda successfully developed the first generation ofhigh conversion efficiency of maximum power point tracking(MPPT) controller in 2010.  To store the power generated by solar panel inthe battery bank. In Shanghai SNEC PV POWER EXPO we Successively got anaward in 2011,2012 “One of the Ten Highlight Products ”;Smart features: With TI28035 powerful smart control chip and efficient MPPT trackingprogram, 12V/24V/48V automatic recognition system, all batteries be defined by users, Display all kinds of working parameters, With free PC software, It’s an Smart MPPT solar chargecontroller. 

2. What is "Smart2"?

Answer: I-Panda update the SMART1 MPPT solar chargecontroller with DC Output function with five control ways forTime Control/ PV Control/ PV&Time Control/ ON/OFF. LAN Communication Portis added. Customer can set the IP Address with cable or WIFI to connect the PC.With LAN Communication customer can monitor the controller freely. That’sSmart2.

3. What is "eSmart"?

Answer: Due to the high-end design of SMART1 andSMART2, I-Panda launched a mini 15A to 40A series MPPT solar charge controller  in 2014 , this mini MPPT solar charge controller is high conversion efficiency at very competitive price,  So we call eSmart series;  

4. What are the difference of three series MPPT controller eSmart, Smart1 Smart2?

Answer: Please see thePDF document. Named Contrast about 3 series MPPT SolarCharge Controller

5. What’s AutomaticRecognition 12V/24V/48V system to charge battery?

Answer: Smart seriescontroller can automatically recognize 12V, 24V, 48V battery , When the controller is connected to the battery,if the battery voltage within DC9V ~DC15V, default is 12V battery; If the battery voltage within

DC18V ~ DC30V, default is 24V battery;If the battery voltage within DC36V ~ DC60V, default is 48V battery.

The controller will automatically run thecorresponding system program if the battery voltage isin the above range, and display system parameters in theLCD; If the battery voltage is not in the scope ofthe above voltage, controller will not be able to work. Therefore, users need to check the connection ofbatteryand battery status.

6. How to set up the battery type?

Answer: Please referto the user manual;

7. What kind ofcomputer operating system can fit for PC software ?

4)Using PING tool to determine the controller PC and routers in the same local area network (LAN);

5)PC communication method is TCP insteadof COM, thePC need to enter the IPaddress of the controller;

6)When the connection is normalwhile can'tcommunicate, please restartthe controller and try again;

10. Why can't set up parameters through PC ? What is thepassword?

Answer: The system can be set up whenthe controllerwas connectedto the PCand shows thecharging parameters. Please askdealers for password and read the usermanual before settingthe parameters.
