Photovoltaic Water Pump Special Inverter Application Scheme

In the current social environment, the main goal of using solar water pump systems is to provide high-quality and energy-saving water supply solutions for remote areas without power supply or power shortages. The system uses the direct current output from the photovoltaic array to drive the water pump to draw water. The system requires no batteries, but stores water in a storage tank for later use. The water source for water storage can be natural water sources such as rivers, lakes, groundwater, or other water sources.

The advantages of applying inverters for photovoltaic water pumps:

(1) No fuel is required, and the cost is lower than that of the fuel pump water system.
(2) Zero carbon emissions;
(3) Long-life system design that has been verified and approved by the market for a long time;
(4) Suitable for insufficient power supply and various harsh environments;
(5) Mobile and full-range power part design;
(6) Simple and fast installation; support various conventional solar modules;
(7) Modularity ensures the reliability of the system and reduces after-sales and maintenance costs;
(8) Compatible with various water pumps, wide adaptability and high efficiency;
(9) Applicable to various standard three-phase asynchronous motor systems;
(10) Compatible with DC brushless motor water pump, adaptive motor parameters;

AC photovoltaic water pump system features:

A. The system does not need to install batteries, and the whole process is powered by solar energy, which is more economical and reliable.
B. The reservoir stores water for subsequent use;
C. The system uses high-efficiency AC submersible/surface pumps to meet different needs.
D. The system is characterized by the use of high power point tracking technology to automatically adjust the operation of the water pump to achieve greater power generation. The system adopts automatic control technology to automatically start and stop sooner or later. It shuts off automatically when the pool is full and the well runs out of water. Take protective measures to prevent the pump from stalling and ensure three-phase balance, thereby extending the service life of the pump and controller.

Wiring:

Solar water pump controller
The output line reactor protects the PDS solar water pump controller from short circuits caused by motor insulation failure, while allowing the motor to reduce motor temperature by smoothing the motor current waveform. It is recommended to use when the distance between the PDS solar water pump controller and the motor exceeds 50 meters. (Note: Actual specifications may vary slightly)

Controller output
When installed at the output of the controller, the line reactor protects the motor from short circuits. The voltage and current waveforms output by the controller are reinforced to prevent the motor from overheating and reduce noise.
Note: Only three-phase AC line reactors can be installed at the output end of the controller.

In order to meet the needs of various pumping applications, solar photovoltaic water pump inverters use high power point tracking and long-established motor drive technology to maximize the output power of solar modules. Support DC and AC input. When sunlight is insufficient, the controller can switch to a single-phase or three-phase AC input such as a generator or battery. Provide fault detection function, as well as motor soft start and speed regulation, easy to use and easy to install.
