Based on the superior performance of NK112 series, our company has developed a series of NK112A solar water pump inverter with automatic voltage boost function to meet the low voltage operation requirements. It simplifies the configuration of solar cell panel and reduces the system cost, which is your ideal choice.
1.Equipped with TI DSP digital control technique and Infineon IGBT power integration module design.
3.Maximum power point tracking(MPPT) algorithm for dynamic VI.MPPT efficiency can be 99%.
4.Fast response speed and good stability.
5.AC and DC input available, but do not use DC and AC at the same time.
6.Remote control, support RS485 protocol.
7. Full protections:Overload, over-current, over-voltage,under-voltage, short circuit, dry pumping, PV reversed connection protection.
8. Widely used in agriculture and forestry irrigation, desert control, solar pasture irrigation, grassland animal husbandry, urban water supply and other landscapes.
