4.MPPT
XX44 Model 20~50A-MPPT Intelligent Solar Controller
Advantages of MPPT technology:
1. Max Power Point Tracking (MPPT) function, with efficiency 30% higher than the non-MPPT system.
2. Advanced AC-DC controlling function, independent voltage stabilization, smooth and accurate control of charging and discharging, battery lifespan prolonged 50%~100%.
3. Coordinate with wind energy, grid power and DG, with the energy utilization order set on spot.
4. Complete display and storage of working data, reservation of records and alarm data for 5 years.
The function of products:
Can Control 1250Wp (DC24V) ~2500Wp (DC48V) PV arrays; wall-mounted and simple installation, completing the control of independent power generation.
Applies to small telecom repeaters, relay stations, and highly reliable facilities in the fields of meteorological and earthquake supervision, petroleum, agriculture, military and so on. The system can safely power loads no more than 150W (DC24V) /300W (DC48V) within 3 successive rainy days.
With abundant power, the system can power some subsidiary facilities, and realizes automatic temperature control, heating in winter and cooling in summer.
Hybrid power utilization, energy input order: solar-wind-grid-DG-battery, when energy at the superior lever is inadequate, energy at the next level will automatically switch in. the order can also be chosen.
With normal sunshine, the system can work without battery, which is convenient for maintenance while the project is still operating (please abide to the instructions or call for information).
Automatic system with no person on duty, MTBF more than 100000 hours.
