Philippines / Three-Phase Pump To Water Tank
SP4007 Three-Phase Solar Inverter for a 5.5kW Well Pump in the Philippines
The water job was simple to understand: lift well water into an elevated storage tank, then let the farm use that stored water with steadier pressure.
The installed system used a SolarSeeker SP4007 7.5kW inverter for a 5.5kW three-phase pump. Fifteen solar panels supplied the PV side, and the cabinet kept the inverter close to the pump controls.

Water Route
The inverter only matters if the tank fills reliably.
1. Source
Well pump
The 5.5kW three-phase pump had to start and run from solar input during the useful daylight window.
2. Control
SP4007 in cabinet
The inverter matched the motor output and allowed the pump to follow available PV power.
3. Storage
Elevated tank
Water stored above the field gives the farm a more useful buffer than direct pumping alone.
Site Notes
Tank, panels, cabinet, and pump side in one system
The useful check is not one photo by itself. The tank shows the water target, the PV array shows the power source, and the cabinet photo shows how the SP4007 was kept accessible for wiring and inspection.



Matching Notes
A three-phase pump needs more than a kW match.
Voltage and current first
The SP4007 is a 380V, 7.5kW, 17A inverter. A different pump may need another model even if the application looks similar.
Tank height changes the work
Pumping into an elevated tank means head and pipe route must be checked, not only the motor power.
Panel count should follow the motor
Fifteen panels worked for this site. A repeat design should check panel model, Voc, Vmp, and local sunlight.

FAQ
Questions from this SP4007 tank supply project
What was installed in the Philippines project?
The project used a SolarSeeker SP4007 7.5kW inverter, a 5.5kW three-phase pump, and 15 solar panels to pump well water into an elevated tank.
Why use an elevated tank?
The tank stores water after pumping and gives the farm a buffer for later distribution. That changes the sizing discussion because lift and tank height matter.
Can every 5.5kW pump use SP4007?
No. SolarSeeker should check voltage, phase, rated current, pump type, head, cable distance, and panel data before confirming the model.
What photos help with model selection?
Send the pump nameplate, well or pump room, tank position, panel area, and cabinet location so the design can be checked against the real site.
Need to pump well water into a storage tank?
Send the pump nameplate, tank height, pipe distance, and panel plan. SolarSeeker will check the inverter range and PV string before quoting.
