1. Simple Introduction
JNTECH Solar Pumping Inverter converts DC power produced by solar panels into AC power required
by the pump. 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 different seasons. The inverter
untilize a high efficiency MPPT algorithm to maximize power harvested from solar panels.
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.
