How to Choose Generators for Well Pumps

Power Requirements and Startup Current

Well pumps need significantly more power during startup than during normal operation. The inrush current can be 6-8 times the running amperage.

Calculate your generator size by multiplying pump horsepower by 1000 watts, then adding 50% for startup surge. A soft start controller can reduce this requirement by up to 40%.

Well Depth and Pump Type

Shallow well pumps work for water sources up to 25 feet deep and typically use less power. Deep well submersible pumps handle depths over 25 feet but require more starting current.

Match your pump type to your actual well depth for optimal efficiency. Using a deep well pump for shallow applications wastes energy and money.

Flow Rate and Daily Water Needs

Calculate your household’s daily water consumption to determine required flow rate. Most homes need 6-12 gallons per minute for comfortable operation.

Higher flow rates require more powerful motors and larger generators. Balance your actual needs against equipment costs to avoid oversizing.

Voltage Options and Generator Compatibility

Most well pumps run on 115V or 240V power with different amperage draws. Dual voltage pumps offer flexibility when connecting to various generator types.

Check your generator’s voltage output and surge capacity before selecting a pump. DC pumps work with solar systems and battery banks without needing AC conversion.

Control Features and Protection Systems

Automatic pressure switches maintain consistent water pressure without manual intervention. Thermal overload protection prevents motor damage during dry running or overheating.

Look for built-in pressure gauges and waterproof switches for convenient monitoring. Quality control systems extend pump life and reduce maintenance needs.

Frequently Asked Questions

What size generator do I need to run a 1 HP well pump?

A 1 HP well pump typically needs a 3500-4000 watt generator to handle startup surge. Using a soft start controller can reduce this to a 2000-2500 watt generator.

Can I run a deep well pump on solar panels?

Yes, DC-powered submersible pumps like the ECO-WORTHY models work directly with solar panels and battery banks. AC pumps require an inverter to convert DC solar power to AC.

How do I reduce the power needed to start my well pump?

Install a soft start controller to reduce inrush current by up to 40%. This allows smaller generators to start larger pumps without voltage drops or failures.

What’s the difference between shallow and deep well pumps?

Shallow well pumps work for water sources up to 25 feet deep and mount above ground. Deep well submersible pumps install underwater and handle depths over 25 feet with higher pressure capabilities.

Do well pumps work better on 115V or 240V generators?

240V operation draws half the amperage of 115V for the same horsepower, reducing voltage drop and allowing smaller wire sizes. However, 115V generators are more common and less expensive.

Final Thoughts

The SoftStart Controller offers the best solution for running existing pumps on smaller generators, while the Aquastrong systems provide complete ready-to-run packages for shallow wells.

Consider your well depth, daily water needs, and available power sources when choosing. DC-powered pumps work great for off-grid solar applications, while dual-voltage AC pumps offer maximum generator flexibility.

Match your pump’s horsepower and voltage to your generator’s capacity, leaving room for startup surge unless you install a soft start controller.
