SP1004 Hybrid Solar Pump Inverter for a 220V Single-Phase Pump in the Philippines
This Philippines home-water project used an existing 220V single-phase pump. The goal was to add solar support while keeping AC power available and without changing the pump motor or removing its capacitor.
This project used a SolarSeeker SP1004 4kW inverter to run a 2.2kW single-phase pump. The system was tested indoors with 220V AC input first, then configured for hybrid input using AC power and about 330V DC solar input from 8 x 600W panels.

AC + DC hybrid

What Was Not Working
The project needed a direct path for the existing 220V single-phase pump.
Residential buildings may need water supply for long hours, and electricity bills can become a real monthly burden. Solar pumping is attractive, but many sites already use a single-phase water pump.
Some conversion approaches require changes to the pump capacitor or motor wiring. This project used SP1004 to drive the existing 220V single-phase pump directly, so the installer could keep the original pump configuration.
System Configuration
SP1004 combined grid input and solar input, with solar power priority.
The installer tested the inverter with 220V AC input indoors before using hybrid input mode. During operation, the inverter can take AC power and DC solar power at the same time, then prioritize solar energy when available.

Field Result
The pump ran well and produced strong water output during testing.
The project video and site images show the pump running after the inverter test. For a home water supply user, the main value is not a complex control cabinet. It is a practical setup that can use solar energy first while keeping AC power available.
For distributors and installers, this case is a practical reference for buyers who already have a 220V single-phase water pump and want solar support with AC backup instead of replacing the pump body.

Selection Notes
What buyers should check before matching a solar inverter to a single-phase pump
Pump nameplate first
Check voltage, rated power, current, phase, pump type, head and flow before selecting a solar pump inverter. For this case, the verified pump load was 2.2kW at 220V single phase.
Hybrid input logic
For home water supply, AC backup and solar priority help maintain pumping when solar input changes during the day.
Do not assume every pump is the same
Different pump types can require different sizing checks. Always verify the actual nameplate current, voltage and operating duty before model selection.
Buyer Path
Where to go after checking your pump
For the SP1 product path
Check the SP1 220V single-phase inverter family used for small pump applications.
For 220V single-phase pump projects
Use this category path for 220V single-phase pump projects and related selection guidance.
For pump and PV sizing
Use the selector to check pump power, voltage, phase and preliminary PV sizing before sending the nameplate.
FAQ
Questions from single-phase pump buyers
Can SP1004 drive a 220V single-phase pump?
Yes, this Philippines project used an SP1004 4kW inverter with a 2.2kW 220V single-phase pump. The pump nameplate should still be checked before model selection.
Why use AC and DC input together?
Hybrid input lets the inverter use solar power first while AC power remains available. This is helpful for home water supply where the pump may need to run outside perfect sunlight hours.
Is this SP1004 case only relevant to one pump type?
No. The key requirement is to verify the actual pump nameplate and application. Voltage, phase, rated power and current should be checked before applying the same SP1 selection path to another pump.
What information should be sent for a model check?
Send the pump nameplate, pump photo, water source, daily running need, AC backup requirement, planned PV panel size, and installation photos.
Have a 220V single-phase pump that needs solar support?
Send your pump nameplate and planned PV panel data. SolarSeeker will check whether SP1004 or another model fits your single-phase motor and hybrid input requirement.
