MPPT Solar Charge Controllers
The MPPT (Maximum Power Point Tracking) solar controller is the essential part of a solar system.These controllers actually detect the optimum operating voltage and amperage of your solar panel array and match that with the battery bank. The result is additional 15%-30% more power output than a PWM solar controller. Although the MPPT solar charge controller is more expensive than its PWM counterpart, it is generally worth the investment for any solar electric system over 200 watts.
Our MPPT controller, ML4830/ML4860 support all 12V/24V/36V/48V Batteries, supporting charging procedures of gel batteries, sealed batteries, open batteries, lithium batteries and other types of batteries, MPPT tracking efficiency can be as high as 99.9%, inbuilt LCD display and RS232 communication makes it flexible while operation.
The ML Series Controller Has Three Different Current For Your Choice:
ML4830 (12V/24V/36V/48V 30A) ML4860 (12V/24V/36V/48V 60A)
Product Feature
1. Advanced double-peak or multiple-peak tracking technology. When the panel has a shadow block or a part of the panel is damaged, I-V curve shows multiple
peaks. The solar charge controller can still accurately track the maximum power point.
2. Built-in algorithm for maximum power tracking. This significantly raises energy utilization efficiency of photovoltaic systems, with
charging efficiency 15% ~ 20% higher than traditional PWM solar charge controllers.
3. Combination of multiple tracking algorithms that can track the optimum working point of I-V curve accurately in a very short period
of time.
4. MPPT tracking efficiency can be as high as 99.9%.
5. Advanced digital power technology, with circuit energy conversion efficiency as high as 98%.
6. Supporting charging procedures of gel batteries,
sealed batteries, open batteries, lithium batteries and other types of batteries.①
7. Current-limiting charging mode. When the power of a solar panel is too large, and the charging current is greater than rated current, the solar charge controller automatically reduces
charging power, thereby making the solar panel work at rated charging current.
8. Supporting the start of capacitive load instantaneous large current.
9. Supporting automatic identification of battery voltage.
10.
LED indicator of malfunction, buzzer alarm, and liquid crystal display of abnormal information. This helps users identify system failures.
11. Supporting historical data storage for up to 5 years.
12. LCD screen display
function. The display enables users to view equipment operation data and status, and modify controller parameters at the same time.
13. Supporting standard Modbus protocol that meets communication needs on different occasions.
14.
Built-in mechanism of over-temperature protection. When the temperature exceeds the preset value, the charging current falls linearly with temperature, therefore
slowing down the rise of controller temperature and avoiding controller damage from high temperature.
15. External battery voltage sampling function. This function prevents line loss from affecting external battery voltage
sampling and ensures greater preciseness of, control parameters.
16. Temperature compensation functions. Charging and discharging parameters are automatically adjusted, thereby extending battery service life.
17. TVS
lightning protection is adopted.
Application
MPPT Solar charge controller is mainly used for solar power station, solar power system for household, solar street light control system, mobile solar power system, DC wind solar generating systems etc applications.
