MPPT 30A Solar Charger Controller
Features:
MPPT solar controller is for off-grid solar system and control the charging and discharging of the battery, especially suitable for the street light system. The controller features a smart tracking algorithm inside that maximizes the energy from the solar PV module(s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.
The MPPT controller charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.
- 12V / 24V auto recognition.
- Advanced maximum power point tracking technology to optimize using the solar system.
- Peak conversion efficiency of 97 %, high Tracking efficiency of 99%.
- Very fast sweeping of the entire I-V curve, several seconds tracking speed.
- Widely used, automatic recognize day/night.
- Timer function with 1-15 hours option for street light.
- Unique dual timer function, enhance the flexibility of street light system.
- Sealed, Gel and Flooded battery option.
- Adopting temperature compensation and correcting the charging and discharging parameters automatically, improving the battery lifetime.
- Electronic protection: over charging, over discharging, overload, short circuit.
- Reverse protection: any combination of solar module and battery, without causing damage to any component.
- Excellent thermal design and nature air cooling.

How do solar panel work?
PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can either be mounted on your roof or on the ground.
The power of a PV cell is measured in kilowatts peak (kWp). That's the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof, but you can also fit solar tiles.
