4kw Jntech Solar Pump Inverter , Soft Start & Soft Stop ,
Fanless Design
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.
2. Product features:
1. Grid or diesel generator can be hybrid at cloudy day or at
night, system is available to work 24 hours per day;
2. Can handle ambient temperature up to 60℃ and Max. relative humidity > 90%;
