Stable 48v Mppt Solar Charge Controller 30A RS485 RS232 For Home System
12/24V /36V/48V 30A MPPT Off Grid Solar Charge Controller For Home System
Off Grid Price M
Features of SR-ML4830
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. MPPT tracking efficiency can be as high as 99.9%.
4. Advanced digital power technology, with circuit energy
conversion efficiency as high as 98%.
5. Supporting charging procedures of gel batteries, sealed
batteries, open batteries, lithium batteries and other types of
batteries.
6. 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.
7. Supporting automatic identification of battery voltage.
8. LED indicator of malfunction, buzzer alarm, and liquid crystal
display of abnormal information. This helps users identify system
failures.
9. Supporting historical data storage for up to 5 years.
10. LCD screen display function. The display enables users to view
equipment operation data and status, and modify controller
parameters at the same time.
Note 1:Only the ML-LI model supports lithium battery charging and discharging function.
