What is a solar pump inverter?

A solar pump inverter is a key part of any solar water pumping system. It converts solar power into the AC power you need and optimizes your pump’s performance. By choosing the right inverter and setting it up correctly, you can maximize your water output, save on energy costs, and have a sustainable water solution that’s right for you.

How do I choose a solar inverter?

Consider the volume of water you need to pump daily. This affects the size of both the pump and the solar array, influencing the inverter selection. Higher water demands may require a more powerful pump and, consequently, a larger inverter.

Do solar water pumps need a specialized inverter?

Solar water pumps are a great way to access water in areas where traditional electricity might not be available. They’re especially useful for irrigation or remote water needs. But to make solar power usable for these water pumps, you’ll need a specialized inverter.

How many watts does an inverter need?

If you have a 1.5 HP pump, its running watts is going to be around 1500 watts, more or less. However, pump motors need a surge of power to start up. In a 1.5 AC pump this is about 3000 watts. Add 25% to 3000 watts and you get 3750 watts. Round that off to 4000, and that is the inverter you need.

How much power does a solar inverter need?

In this example, you would need an inverter capable of handling at least 4.55 kW to adequately power your solar pump system, accounting for current needs, inefficiencies, and potential future expansion.

How much power does a solar pump use?

But if you run the pump for 15 minutes twice an hour, power use goes up to 1000 watts. You do not have to worry too much about the calculations though. As long as the inverter can handle the surge watts, you should be able to run the pump without trouble. Of course the rest of your solar system must be of sufficient size too.
