Part two: About the controller

3 series 16 models MPPT Solar Charge 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/48V Automatic Recognition 20A ~ 60A

3.I-P-eSmart Series 12V/24V/48V Automatic Recognition 15A ~ 40A

1. What is "Smart"?

Answer: Due to high cost of panels, low conversion efficiency of ordinary PWM controller, I-Panda successfully developed the first generation of high conversion efficiency of maximum power point tracking(MPPT) controller in 2010.  To store the power generated by solar panel in the battery bank. In Shanghai SNEC PV POWER EXPO we Successively got an award in 2011, 2012 “One of the Ten Highlight Products ”; Smart features: With TI28035 powerful smart control chip and efficient MPPT tracking program, 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 charge controller. 

2. What is "Smart2"?

Answer: I-Panda update the SMART1 MPPT solar charge controller with DC Output function with five control ways for Time Control/ PV Control/ PV&Time Control/ ON/OFF. LAN Communication Port is 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’s Smart2.

3. What is "eSmart"?

Answer: Due to the high-end design of SMART1 and SMART2, 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 the PDF document. Named Contrast about 3 series MPPT Solar Charge Controller

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

Answer: Smart series controller 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 the corresponding system program if the battery voltage is in the above range, and display system parameters in the LCD; If the battery voltage is not in the scope of the above voltage, controller will not be able to work.
