Whatever the source of electricity, we recommend using batteries between the source and the motor. This applies whether you're using AC power, solar panels, or other sources.
Why Use Batteries with AC Power?
Motor Protection
- Batteries provide clean, stable DC power
- Protect motor from voltage spikes
- Smooth out power fluctuations
- Extend motor lifespan
Backup Capability
- Pump continues during power outages
- Batteries charged while power available
- Seamless transition when grid fails
- True backup water access
How AC Power Works with Simple Pump
- AC power charges deep-cycle batteries
- Batteries provide 12V or 24V DC to motor
- Motor operates on clean, stable power
- Result: Reliable pumping with backup capability
Recommended Setup
Components Needed
- Battery charger (AC to DC)
- Deep-cycle batteries (12V or 24V system)
- Simple Pump motor assembly
- Charge controller (optional but recommended)
Battery Sizing
Battery capacity depends on:
- Daily water needs
- Desired backup duration
- Motor specifications
- Charging availability
Why Not Direct AC-to-Motor?
Simple Pump motors are designed for DC operation:
- 12V motors: Standard automotive-type power
- 24V motors: Higher efficiency for deeper wells
AC-to-DC converters without battery buffering can:
- Produce unclean power
- Cause motor heating
- Reduce motor lifespan
- Void warranty if damage occurs
The Best of Both Worlds
With AC charging and battery backup:
- Normal operation: AC keeps batteries charged, motor runs as needed
- Power outage: Batteries provide continued pumping
- Extended outage: Switch to hand operation
This configuration gives you automated daily water access plus emergency backup capability.
Switch to Hand Operation Anytime
Remember, every motorized Simple Pump can be operated manually:
- Remove motor drive unit
- Attach lever arm
- Pump by hand
This ensures water access regardless of power availability.
