Product Description:


DC Solar Pumping System can be applied to daily use (ground water), agricultural irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering, and so on. Solar water pump System is dispensed with energy storing devices, and stores water instead of electricity. It improves the reliability of the device, at the same time, it lowers the construction and maintenance costs of the irrigation system dramatically.

In recent years, with the promotion of the utilization of new energy resources, Solar Pumping System is more and more used in municipal engineering, city centre squares, parks, tourist sites, resorts and hotels, the landscapes and fountain irrigation systems in the residential areas.

Technical Features

Optimization of Single Pump System

A single solar irrigation system consists of only one pump, a power -matched solar array and an inverter . The aim of optimization is to reduce the amount of PV modules as much as possible on the premise of filling the requirement of head and capacity. The rotational speed of pump is regulated according to the irradiation on the solar array; when the sunlight reaches its peak, the pump runs at the rated speed, and the output approaches the peak power of the solar array; when the sunlight is less abundant, the speed of pump varies bellow the range of the rated speed; when the speed as low as the capacity becomes zero, the solar pumping system stops working. So, there are big differences between solar irriation systems and traditional pumping systems in system design, and the system should be optimized according to the requirements of head, capacity, and local conditions of sunlight.

•Determine the optimal average daily operating time and the range of speed governing.
•Choose the optimal head and capacity of the pump.
•Determine the maximum power of PV modules, the best working voltage and method of connection.
Optimization of Multi-pump Systems:
There are several pumps in a multi-pump system. The pumps can be driven either by only one high-power inverter, or by several matching inverters. In the case of large capacity demand, the operation of the multi-pump system is more flexible. By switching solar arrays and pumps, all of the pumps run in MPPT mode when the sunlight is abundant, while some pumps will be shut down and all solar arrays supply power intensively for the rest running pumps when irradiation is weak. Based on the optimization of single pump system, the range of speed can be further optimized, and the photovoltaic(PV) pumping system always works with high efficiency.

Q:Solar water heater before the booster pump is now changed into tap water how to get
If your water pressure is sufficient, you can directly on the water pipe connected to the water pipe on the line.
Q:Solar water heater booster pump how to use automatic valve
Choose to use manual switch to force the booster pump can also start, just remember to turn off the pump after the full.
Q:On the issue of pumps and solar panels
But the solar panels, then the general pump motor are AC, solar energy is the first DC output so the first to have an inverter, the other in order to ensure that no sun, such as night or cloudy can be used and to ensure that the inverter circuit voltage and current stability are by the solar panels
Q:What is a photovoltaic pump?
Photovoltaic pumps, also known as solar water pumps, mainly by the photovoltaic pump and pump components. Specific application, and then according to the different head and daily water demand with the corresponding power of the solar array, collectively referred to as photovoltaic water system.
Q:What is the difference between centrifugal pumps and circulating pumps?
Often, it is not possible to clearly delineate the obvious boundaries of the two pumps you are talking about.
Q:The problem of installing pressurized water pump in solar hot water outlet pipe
Household pipe booster pump in the installation of the need to pay attention to the matter more, but these considerations for the subsequent work and production of great impact, we often say that sharpening workers do not mistake. Only to the precautions to prepare thoroughly, for the use of the product we can be more handy, the effect will be better.
Q:Solar water heater automatic pressurized water pump does not turn how maintenance
For this place you do not understand, there are several ways for your reference: you can ask the professionals to see for you, to solve; can go to an experienced person to ask for advice, learn to master it;
Q:What is the pump for solar hot water
Traditional solar water heaters are falling into the water. The water pressure depends on the distance from the roof to the room, the greater the distance, the greater the water pressure. If the water pressure requirements, there are two ways
Q:Solar water heater computer controller shows Sheung Shui, booster pump does not start Sheung Shui, how to do
First look at the control panel signal line is not bad contact, check the water level probe, if these aspects are no problem, then you turn off the power after 3 minutes, at the start.
Q:Does the balcony wall - mounted solar energy require a circulating pump?
The so-called natural circulation, is your home balcony collector (flat collector or U-tube collector) to absorb solar light heat, the collector medium using cold water sink hot water floating automatically heat will be passed to the tank
