1. Simple Introduction Of JNTECH Solar Water Pumping System
JNTECH solar pumping system consists of solar panels, solar pump inverter, AC pump and water storage device.
Solar pump inverter converts the DC power produced by solar panel into AC power to drive the pump work, a
microprocessor inside inverter continuously monitors available energy levels and adjust pump frequency for
achieving max use of solar energy.
Meanwhile, AC input module or AC power pack can be added in, which allow PV, state grid, DG, multi-sources
work as complementary or by-pass, to achieve system working 24 hours per day.
2. Inverter Features:
1:1 match with single phase AC pumps with strong overload capacity;
Solar power tracking efficiency can reach 99% with advanced MPPT
algorithm;
IP65 design, Can continuous full-load operation between -25℃ to
+60℃;
Remote monitoring start and stop with RS485 & GPRS
communication;
Perfect protection system: undervoltage protection, overload
protection, overvoltage
protection, overcurrent protection, dry protection, short-circuit
protection, etc.;
High efficiency, low noise, fanless design, long system lifespan,
safe and reliable;
Reduce starting power and 30% more water output with advanced
inverter control
algorithm;
Reduce solar panels configuration and save costs with low solar
operating voltage.
