Product Description


What is MPPT controller?

This type MPPT (Maximum Power Point Tracking) controller is the third generation mppt solar charge controller, it can lock on the point to harvest the maximum energy and deliver it to the battery. 

Which combined with the second generation of high conversion efficiency, back-light LCD display, control mode, connect way, internal structure etc. features, also optimized the following points:


1. Increase all kinds of protection function to be used more reassuring.

2. Add the LOAD sampling to be used more clear of output load.

3. Wider PV Input voltage than the second generatrion, so it's suitable for more kinds of PV modules.

4. Reduce the static standby self-consumption, energy saving and more simply for small system.

What features of your MPPT controllers?

1. MPPT control mode, peak efficiency up to 99%, saving 30%~60% solar panel than traditional PWM controller.



                                            Maximum Power Point Curve


2. Charge mode: three stages : Constant Current Charging(Bulk Charging), Constant Voltage Charging(CV) and Floating Charging(CF) for rapid, efficient, and safe battery charging.  (activate the battery performance, and prolongs service life of the batteries)

3. Discharge mode: ON/OFF mode, PV voltage control mode, Dual Time control mode, PV&Time control mode;

4. Customers can choose battery types: (Flooded, Sealed lead acid, Gel battery) charging, Other types of the batteries can also be defined;

5. Most information could be provide by LCD like: System type, PV input voltage, PV input current, Day/Month/Total generated energy, battery type, battery voltage, charging current, charging power, Load current, Load power etc .

6. RS485 communication, we can offer communication protocol also, it’s convenient for user’s integration management.
