MPPT technology introduction:
MPPT means maximum power point tracking. It makes the solar panels work at maximum point(ext Point B) by using power conversion technology. eMPPT is the new charge controller researched and developed by our company, and it uses the MCU to track the maximum power point of solar panels intelligently to generate more power from the solar panels.
About MPPT Charging: Bulk charging, Absorption charging, Float charging
(1) Maximum Power Point Tracking technology
The controller uses Buck conversion circuit and MCU technology to track the maximum power point to implement the maximum output power of solar panels in different illumination intensity and temperature. The MPPT algorithm increases efficiency of your PV system and decreases the quantity of solar panels.
(2) Multi-stage Charge Control
The starting charging voltage of battery is different, the controller will use the different charging strategies to finalize the charging process. When starting charging voltage of battery is lower than 12.4V (for 12V battery), battery will go through three stages as Bulk, Absorption and Float charging. When starting charging voltage of battery is higher than 12.4V (for 12V battery), battery will go through two stages as Bulk and Float charging.
Bulk Charge, Absorption Charge, Float Charge.
(3) Charge Voltage Temperature-compensated
(4) Discharge Control
(5) Protection against Reverse Connected Battery
(6) Protection against Reverse Connected Solar Modules
(7) Reverse Current Protection
(8) Over temperature Protection
(9) PV Over voltage Protection
(10) Current-limited for Excessive Charging Current
(11) Load Output Overload Protection
Applications:
- Solar portable light
- Solar Home systems
- Roof top solar solutions
