Untitled DocumentDescription 40A 12V/24V/48V auto MPPT solar charge controller with RS232 communication Max.PV input 100V DC
Introduction This e-SMART MPPT (maximum Power Point Tracking) solar charge controller is a smart solar controller with automatic recognition 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 function. Main Features 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 option of discharge: on mode and off mode and PV voltage(solar) 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, charging current, charging power, working condition. 8. RS232 communication, we can offer communication protocol also, it's convenient for user's integration management.
