20 AMP SRNE Ml2420 12 Volt MPPT Solar Charge Controller With LCD Display
MPPT 12V solar charger controller with LCD display
1. With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.
2. built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems,and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.
3. A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
4. The product boasts an optimum MPPT tracking efficiency of up to 99.9%.
5. Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%.
6. Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc.
7. The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
8. Instantaneous large current startup of capacitive loads is supported.
9. Automatic recognition of battery voltage is supported.
10. LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults.
11. Historical data storage function is available, and data can be stored for up to a year.
12. The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.
