To select the right inverter, you must know the wattage of your well pump. Typically, residential well pumps range from 0.5 HP (370 watts) to 2 HP (1,500 watts), but the exact wattage

That means a 1 HP water pump requires at LEAST 750 watts of solar power to run, but to run effectively throughout the day a few hundred more watts should be added. Plus, an inverter always incurs a bit

You can run a water pump with a 1000W inverter, but only if the pump''s running and startup wattages fit within that limit. Keep in mind, pumps often need 2-3 times their running power at

A general rule is to choose an inverter with a power rating at least 20% higher than the wattage of your pump to account for surge loads and future expansion. There are two main types of inverters:

Inverters come in various sizes, typically measured in watts (W) or kilowatts (kW). The size of the inverter should be equal to or slightly larger than the calculated power requirements of the

For a standard 1HP (746 Watts) AC water pump, you need a solar inverter with a continuous rating of at least 1500W and a peak or surge rating of 3000-4000W to handle the massive starting current.
