1. Simple Introduction Of JNTECH Solar Water Pumping System
JNTECH Solar Pumping Inverter converts DC power produced by PV module into AC power required by the pump motor. A microprocessor inside inverter continuously monitors available energy levels and adjust pump speed, matching energy required to energy available. This enables the system to operate under varying solar insolation levels, and provide water throughout the day and through different seasons. The inverter untilize a high efficiency MPPT algorithm to maximize power harvested from PV module.
Meanwhile, the application of AC PowerPack add grid utility/DG as power supplement or backup for solar energy, can keep pumping system working 24 hours a day.
The power drawn from AC source is adjustable according to the intensity of solar energy.
2. Product features:
1. Grid utility work as supplement when sun radiation is unavailable, support system working 24 h/day;
2. Full automatic unattended operation;
3. Soft start controlling in rush current, to avoid motor burning;
4. Max. Power Point Tracking (MPPT) control algorithm of Solar Pump Inverter for optimum solar performance.
5. IP65 design for machine, don't need extra box.
6. 3 years warranty for solar pump inverter.
7. Complete system protection function and long lifespan.
8. Remote monitoring and communication function, can control its start and stop remotely.
9. ROI is only less than 2 years compared to diesel generator.
10. Wide application with all kinds of PV modules and traditional AC pump.
