How to choose solar well pump from China MASTRA

Welcome to China MASTRA news center, today we're going to talk about clear and environmental way of utilizing water pump to get living resource. Let's start with off-the-grid lifestyle, off-the-grid or off-grid is a characteristic of buildings and a lifestyle designed in an independent manner without reliance on one or more public utilities. The term "off-the-grid" traditionally refers to not being connected to the electrical grid, but can also include other utilities like water, gas, and sewer systems, and can scale from residential homes to small communities. Off-the-grid living allows for buildings and people to be self-sufficient, which is advantageous in isolated locations where normal utilities cannot reach and is attractive to those who want to reduce environmental impact and cost of living. Generally, an off-grid building must be able to supply energy and potable water for itself, as well as manage food, waste and wastewater.

Although we China Guangdong Ruirong Pump Industry Co., Ltd. enjoys great advantage in developing and producing large size and large motor power submersible pump, we still keep developing popular products, like solar DC pump sets, and one question I commonly get from my clients is when building an off-grid power system, is whether they can run a deep water well pump from a solar system. So, today I decided to answer that question for everyone.

Is it possible to run a submersible solar well pump? Yes! With a properly sized solar system, you can run a well from solar power. You generally have two options for this, an AC pump with inverter, or a MASTRA DC powered well pump designed for use in an off-grid systems.

Since a solar well pump could easily be the biggest electrical load in your off-grid system, it is worth taking the time to consider your options. Below I’ll go over whether you should choose an AC pump or DC pump for your homestead.

· Choosing a Deep Well Submersible Pump for Use with Solar Power

When designing a solar well pump system, you have two main options for submersible pumps: typical AC pumps, and purpose built DC pumps.

· AC Water Pumps

The biggest advantage of our MASTRA AC pumps is that they are by far the most commonly used. Since all grid connected homes run of AC power, pretty much every submersible pump in the China runs off either 220 or 380 volts AC. This means that you may already have an AC pump, or can get one in a relative lower price. Also, since these pumps run on a higher voltage, you may save money on wiring costs, since higher voltages can run on thinner and cheaper wire.

The biggest disadvantage to run a MASTRA AC pump on solar is that you will need a high power inverter to run the pump, which will add several hundred to the final price. Inverters also reduced the overall efficiency of the solar system when compared to running directly from DC power, which means you may have to increase the number of solar panels or size of your battery bank to account for the loss.

· DC Water Pumps

The biggest advantage of running a MASTRA DC water pump on an off-grid system is that they are higher efficiency (not needing an inverter). This means that usually, if you are buying a new pump then choosing a DC pump is the lowest cost choice, when you consider the potential for savings on inverter, battery, and solar panel capacity. We can offer you 24V-110V, 0.2kw-1.5kw options, you may make decision based on your requirement, or you may also offer the data you need we would like to help you to choose right models. 

The biggest disadvantage to choose a MASTRA DC pump is that you will probably have to special order a new one, as DC solar well pumps are not very common. They also tend to run on lower voltages, which means extra costs if you have a long run of wire between your batteries and your pump. DC pumps also tend to only be offered in lower to medium capacity models, so if you have high water usage, you may have to stick with an AC pump.

Anyway, warmly welcome you to contact us for more information about solar AC/DC well pump.
