2.1 Introduction to pv pump inverter
Photovoltaic pump system is different from the traditional ac pump application
system, the photovoltaic pump system is the use of solar cells convert solar
energy into electrical energy directly, and then driven by photovoltaic pump
inverter ac motor drives the pump, such as jiang river lake from a deep well
water source water, and then transported to the destination, to meet the needs
of the (user) on the water of the system is mainly composed of four parts: the
photovoltaic array photovoltaic pump inverter single-phase or three-phase ac
pumps, as well as the pipeline and photovoltaic array absorbs sunlight
radiation energy storage device, is transformed into electrical energy, for the
whole power system power supply
Photovoltaic pump inverter as an important part of photovoltaic pump system, it
will be a photovoltaic array output direct current into alternating current (ac)
drive pumps, according to the changes of the intensity of sunlight in real time to
adjust the output voltage and frequency, to achieve maximum power point
tracking, maximize the use of solar energy JNPxH series inverter on the basis
of traditional photovoltaic pump inverter, strengthen the function of ac input
complement, in the case of photovoltaic energy shortage, ac input energy can
according to demand to supplement, in order to ensure the normal supply of
users in the night or cloudy days
Warning
！
The inverter cannot be connected to a photovoltaic group with a positive or
negative grounding.
