1. Simple Introduction Of JNTECH 25HP(18.5kw) 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.
