SP3 220V Three Phase Solar Pump Inverter
SP3 is a 220V three phase solar pump inverter for irrigation, farm water supply, building water systems, and dealer pump packages that already use 220V three phase pump motors. Choose SP3 when phase conversion is not needed and the pump should run directly from a matched 220V three phase solar drive.
Quick Decision
SP3 is for 220V three phase pump systems, not phase conversion
SP3 is the direct 220V three phase path in the SolarSeeker SP series. It is different from SP1 single phase output, SP2 phase conversion, and SP4 380V three phase systems.
Choose SP3 for 220V three phase pumps
Use SP3 when the pump motor is 220V three phase and does not need phase conversion.
Choose SP2 for phase conversion
Use SP2 when the site input is single phase but the pump is three phase.
Choose SP4 for 380V pumps
Use SP4 for 380V three phase pumps, larger irrigation systems, and higher-power projects.
Add cabinet protection if needed
For outdoor, dusty, or humid sites, ask SolarSeeker about cabinet installation.
Installation Video
Watch SP3 wiring and commissioning before you quote the project
The video is embedded here so installers and dealers can check the wiring flow without leaving the page. For SP3 projects, always confirm the pump is 220V three phase and check rated current before shipment.
PV input
Check DC string voltage and panel power margin.
Pump output
Confirm 220V three phase motor wiring and rotation.
Nameplate check
Match kW, rated current, head, and flow before order.
Model Selection
SP3 model selection guide for 220V three phase pumps
Choose the right SP3 model from pump kW, rated current, head, flow, and installation environment. For irrigation or long daily operation, SolarSeeker should confirm the PV array and protection margin before shipment.
| Model | Motor Power | Input Current | Output Current | Suggested PV Power | Typical Application |
|---|---|---|---|---|---|
| SP3-0.75 | 1HP / 0.75kW | 2.0A | 1.8A | 1.5kW | Small farm or facility pump |
| SP3-1.5 | 2HP / 1.5kW | 3.8A | 3.6A | 3.0kW | Small farm irrigation |
| SP3-2.2 | 3HP / 2.2kW | 5.5A | 5.2A | 4.4kW | Irrigation and water supply |
| SP3-4.0 | 5HP / 4.0kW | 9.5A | 9.0A | 8.0kW | Farm irrigation pump |
| SP3-7.5 | 10HP / 7.5kW | 18.0A | 17.0A | 15.0kW | Larger irrigation or facility water |
| SP3-15 | 20HP / 15kW | 36.0A | 34.0A | 30.0kW | High-flow 220V three phase system |
Sizing note
As a first estimate, many 220V three phase pump systems start with PV array power around motor power x 2.0. Add margin for high head, long cable distance, cloudy seasons, or longer daily pumping targets.
Where SP3 Fits Best
SP3 is for 220V three phase irrigation and water supply pumps
SP3 is practical for sites that already use 220V three phase pump motors and need solar pumping control without changing the pump type. It is suitable for distributors, pump dealers, irrigation contractors, and EPC teams that serve 220V three phase pump markets.
Farm irrigation pumps
Use SP3 for orchards, vegetable farms, greenhouses, and medium-size crop plots with 220V three phase pumps.
Building and facility water supply
Use SP3 for apartments, schools, resorts, workshops, and facility water systems where the pump is 220V three phase.
Dealer-ready 220V three phase packages
Pair SP3 with a matched pump, PV array, cable, protection parts, and cabinet when the installation environment requires it.
Field Reliability
Built for stable 220V three phase solar pumping
SP3 should be selected from real pump data, not only horsepower. Once the motor phase and voltage are correct, the page focus is stable daily water output, easier commissioning, and fewer field mistakes.
Start waiting function
SP3 waits until solar energy is enough before starting the pump, helping reduce repeated startup attempts under weak morning light or passing clouds.
Simplified operation interface
The operation interface reduces unnecessary parameter work for common pump matching, which helps distributors and installers support more sites.
50掳C operation
SP3 is designed for hot pump rooms, field cabinets, and tropical or dry-season irrigation sites where ambient temperature can rise during the day.
Technical Parameters

Product Path
SP3 vs SP1, SP2, and SP4
The fastest way to avoid wrong selection is to check pump voltage and phase first. SP3 is for direct 220V three phase pumping, not single phase pumps or 380V systems.
| Product Path | Use When | Avoid When | Next Step |
|---|---|---|---|
| SP1 | Pump is 220V single phase | Pump is three phase | Compare SP1 |
| SP2 | Site input is single phase, pump is three phase | No phase conversion is needed | Compare SP2 |
| SP3 | Pump is 220V three phase | Pump is single phase or 380V | Send SP3 specs |
| SP4 | Pump is 380V three phase | Pump is 220V | Compare SP4 |
Before Quotation
What information should you send for SP3 sizing?
For 220V three phase solar pumping, model selection depends on more than pump kW. Send the nameplate and working conditions so SolarSeeker can confirm current, panel sizing, and cabinet needs.
Pump voltage and phase
Confirm the motor is 220V three phase.
Rated current
Match output current and protection margin.
Head and flow
Check whether the pump curve fits the system.
Outdoor conditions
Decide whether a cabinet or extra protection is needed.

FAQ
SP3 220V three phase solar pump inverter FAQ
What is SP3 used for?
SP3 is used for 220V three phase pump systems that need solar pumping control. It fits farm irrigation, building water supply, facility water transfer, and dealer pump packages where the pump motor is already 220V three phase.
Is SP3 different from SP2?
Yes. SP2 is for single phase input to three phase output. SP3 is for 220V three phase pump systems where phase conversion is not needed.
Can SP3 run a 380V three phase pump?
No. SP3 is a 220V three phase solar pump inverter. For 380V three phase pumps, use the SolarSeeker SP4 380V three phase solar pump inverter.
What SP3 model should I choose for a 4.0kW pump?
For a typical 4.0kW or 5HP 220V three phase pump, SP3-4.0 is the first model to check. SolarSeeker should confirm rated current, head, flow, cable distance, and PV array before final quotation.
Does SP3 need a solar pump cabinet?
For indoor or protected pump rooms, a basic installation may be enough. For outdoor, dusty, humid, coastal, or unattended sites, SolarSeeker recommends checking a solar pump cabinet or other protective installation method.
What information should I send for an SP3 quotation?
Send a pump nameplate photo, rated power, voltage, phase, rated current, total head, required flow, cable distance, solar panel plan, installation environment, and project country.
