48V Solar Charge Controller 30A
New appearance design support 12/24/36/48V batteries off grid solar charge controller mppt
Product Description
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.

FAQ:
Q: How many charging mode does the controller have?
A: There are two charging modes. There are PWM and MPPT. MPPT is
the most advanced. Srne have already developed MTTP charge
controller with high performance, reliability, efficiency and fast
tracking speed.
Q: What's the difference of the PWM charge controller and MPPT
charge controller?
A: 1. MPPT controller uses maximum power tracking technology,
compared to the PWM controller, the MPPT can generate more
electricity with the same solar panels.
2. MPPT controller has low requirement of solar power system
voltage, if the line or component parts damage the voltage, using
MPPT controller does not affect the system generating.
3. MPPT controller can detect the temperature of the battery, then
adjust the temperature by itself, the solar panel can charge the
battery more efficiency.
Q: Why should the controller have temperature compensation
function?
A: As temperature rises, electrochemical activity in the battery
increases. Similarly, as temperature falls, electrochemical
activity decreases. Therefore, as temperature rises, charging
voltage should be reduced to prevent overcharge, as temperature
falls, charging voltage should be increase to avoid undercharge. In
general, to assure optimum service life, use of a temperature
compensated charger is recommended.
Q: How does your factory carry out quality control?
A: Quality is our priority. Our QC always attached great importance
to quality control from the very beginning to the end of the
production. Each product will be fully assembled and carefully
tested before packed.
