Product Name: SFT-eS MPPT Solar Controller

Product description: This is a maximum power point intelligent tracking(MPPT) solar energy charging and discharging controller(MPPT), which is 30 % to 60 % higher than the traditional controller charging efficiency.

Product details

The charging mode is MPPT; The conversion efficiency is up to 99 %, which can save 30 % to 60 % solar panel compared with traditional controller.
2, 12V/24 V/48V system automatic identification, easy for users to use in different systems;
3, 12V/24 V/48V system, PV input maximum DC 100V;
4, charging mode: Three levels charge(constant current, constant pressure, floating charge), effective to extend the life of the battery;
The discharge mode has a constant open mode, a constant off mode, and a PV voltage(sunlight) control mode.
Customers can choose to charge 4 types of batteries(sealed lead-acid batteries, discharge batteries, colloidal batteries, nickel cadmium batteries), and can customize other types of batteries;
The controller digital tube displays the battery voltage and charging current; The upper computer displays various parameters, such as model, PV input voltage, battery type, battery voltage, charging current, charging power, working state, etc..

8, RS232 communication, and can provide communication protocol, facilitate customer integration management;
9. Endless merger;
10, the product passes CE, ROHS, FCC certification; Can cooperate with the customer to pass the certification.
11, normal warranty period of two years, and can provide 3 to 10 years extended warranty services;
