Philippines / Diesel Pump Replacement
SP4005 Solar Pump Inverter Running a 4kW Rice Irrigation Pump in the Philippines
The farmer was not trying to build a show project. He needed water in the rice field without starting a diesel generator every time the pump had to run.
The site used a SolarSeeker SP4005 5.5kW inverter, a 4kW pump, and 10 pieces of 550W solar panels. During the field recording, water was still coming from the pipe at 5 PM, when the sun was already weaker than the midday test window.

Before The Change
The generator solved the water problem, then became its own problem.
The farm already had a practical pumping habit: run the pump when the field needed water. The pain was what sat behind that habit. Fuel had to be bought, the generator had to be watched, and the pump cost money every time it ran.
Old routine
Fuel first, water second.
The pump could run only after diesel and generator checks were handled.
New routine
Sunlight drives the pump during the irrigation window.
The 10-panel array was sized around this 4kW farm pump job.
Result to check
Water at the pipe, not only inverter power on the display.
The field note recorded steady flow at 5 PM.
Field Sequence
Start with the rice field, then check the equipment behind the water
The photos are useful when they stay in order: water at the pipe, the small PV array on the farm, the inverter before installation, and the wired control box. Mixed together, they look like a gallery. In sequence, they tell an installer what must be checked.
Do Not Copy Blindly
SP4005 is the clue. The pump nameplate is the decision.
The confirmed working setup used a 5.5kW SolarSeeker inverter and a 4kW pump with 10 pieces of 550W panels. Pump voltage and phase should still be confirmed from the actual pump label before a repeat quote.
For another rice farm, SolarSeeker would check pump voltage, phase, rated current, pipe distance, water source, and daily irrigation target before confirming whether SP4005 or another inverter path is the right fit.
For A Similar Farm
Use this case as a starting point, then size the system from the pump
A rice farm with diesel cost pressure usually wants a quick answer. The fastest useful path is not a product list. It is a short check of the pump, the water job, and the site photos.
FAQ
Practical questions from this rice farm setup
What was installed on this farm?
The confirmed setup used a SolarSeeker SP4005 5.5kW inverter, a 4kW pump, and 10 pieces of 550W solar panels for rice field irrigation.
Why replace the diesel generator?
The farmer wanted to reduce fuel buying, generator operation, and maintenance work during irrigation. Solar pumping moved that daily power source to the farm’s daytime sunlight.
Why mention the 5 PM water output?
Late afternoon is a more useful check than noon only. It shows whether the pump can still produce water when available solar power is lower.
What should another farmer send before choosing a model?
Send the pump nameplate, water source, pipe distance, target irrigation time, panel plan, and photos of the field and pump area.
Have a diesel pump you want to stop feeding?
Send the pump nameplate, water source, pipe distance, and rice field photos. SolarSeeker will check the inverter range and panel plan before quoting.
