CFJ Hybrid Solar Pumping Controller
The CFJ variable frequency drive is an advanced hybrid controller designed for solar pumping systems. Thanks to its MPPT technology, it optimizes the performance of photovoltaic panels in real-time. It allows for flexible power supply, automatically switching between solar energy and the electric grid or diesel generator, ensuring continuous water supply even during periods of low irradiance.
Applications
- MPPT Function: Maximum yield in all environmental conditions.
- Pressure Control: Variable speed to maintain constant pressure.
- Hybrid Mode: Automatic management between solar and grid/generator.
- Integrated protections: Dry run, overvoltage, and phase loss.
