Choose the right SolarSeeker product path
Start from the product type if you already know what you need. If not, send the pump nameplate and we will recommend the inverter, controller, pump, cabinet, or kit.
Solar Pump Inverters
SP1-SP4 cover 220V single-phase, 220V three-phase, 380V three-phase, and single-to-three-phase solar pump inverter requirements.
This path is best when the buyer already has an AC pump motor and needs MPPT control, soft start, dry-run protection, and stable daily water output from PV power.
For distributor stock planning, separate the range by local voltage first, then by pump power, rated current, well depth, and installation climate.
View invertersPump Controllers
SP5 PV pump controller and SP6 submersible pump controller are for projects where pump protection and simplified field control are more important than a standard inverter-only package.
Controllers are useful for repeat installations because wiring, fault handling, and daily operation can be standardized for the installer team.
Choose this path when the project is focused on submersible pump reliability, PV input control, or a compact controller solution for wells and irrigation points.
View controllersSubmersible Pumps
Submersible well water pump selection starts from well depth, dynamic water level, required flow, total head, outlet size, and working hours per day.
A pump that is too large wastes PV capacity, while a pump that is too small cannot meet irrigation or livestock water demand in the dry season.
Use this path when the buyer wants SolarSeeker to match the pump body together with the inverter, controller, cable, and panel array.
View pumpsSolar Pump Cabinets
Solar pump cabinets bring the inverter, breakers, surge protection, wiring terminals, switches, indicators, and optional monitoring into one field-ready enclosure.
They are especially useful for EPC projects, dusty farms, high-temperature sites, and OEM buyers who need consistent installation quality across many systems.
Choose a cabinet when the project needs safer wiring, easier commissioning, IP-rated protection, or customer branding for dealer channels.
View cabinetsSolar Pump Kits
Solar powered well pump kits combine the main electrical and hydraulic parts into a matched package: panels, inverter or controller, pump, cable, accessories, and selection support.
Kits reduce mismatch risk for buyers who do not want to calculate PV string voltage, pump load, protection devices, and installation accessories separately.
This path works well for rural water supply, dealer-ready packages, pilot projects, and repeat well installations with similar flow and head requirements.

What is a solar water pump inverter?
A solar water pump inverter converts DC power from solar panels into stable AC output for pump motors. It uses MPPT technology to harvest available sunlight, adjusts pump speed as solar input changes, and protects the pump during abnormal field conditions.
Unlike a basic solar pump controller, a solar pump inverter actively manages frequency, voltage, motor speed, dry-run protection, overload protection, and daily start-stop operation for professional irrigation, deep-well, livestock, and remote water supply projects.
DC to AC conversion
Solar panels feed the inverter; the inverter drives the AC pump motor.
MPPT control
Tracks changing sunlight to improve daily water output.
Auto start-stop
Runs when solar energy is enough and stops when sunlight is weak.
Pump protection
Reduces pump damage from dry running, overload, voltage faults, and overheating.
Inverter Range
Choose Solar Pump Inverters by voltage and phase
Start with the pump motor nameplate. Voltage, phase, power, rated current, well depth, and water demand decide which product path fits the project.
Voltage Category
220V Solar Pump Inverter
For SP1 220V single-phase, SP3 220V three-phase, and small to medium field water projects.
This category is common in Southeast Asian farms, village wells, and smaller irrigation sites where 220V pumps are easier to source and maintain locally.
Selection should check motor rated current, PV input voltage range, daily water target, cable distance, and whether the pump is single-phase or three-phase.
Open 220V categoryVoltage Category
380V Solar Pump Inverter
For SP4 three-phase deep wells, industrial pumping, large irrigation, and EPC water projects.
380V systems are preferred when pump power is higher, cable runs are longer, or the project needs stable operation for deep boreholes and large water demand.
Buyers should confirm pump kW, rated current, maximum head, dry-run risk, ambient temperature, and whether a cabinet is needed for protection and maintenance.
Open 380V categoryPhase Conversion
Single to Three Phase Inverter
For SP2 applications where a single-phase supply or PV input needs to drive a three-phase pump.
This path is useful when the customer already owns a three-phase pump but the site does not have reliable three-phase grid power.
It can reduce replacement cost, but the motor data must be checked carefully so the inverter output, overload capacity, and PV array size match the pump load.
Open phase conversion
SP1 220V Single Phase
For homes, wells, gardens, small farms, and 220V single-phase pump projects.
SP1 is usually the simplest entry point for dealers selling to smallholders because the pump voltage is familiar and installation teams can commission it quickly.
Use it when the water source is moderate depth, the pump power is not high, and the buyer wants an economical solar pumping upgrade without changing the whole water system.
View SP1
SP2 Phase Conversion
For single-phase input sites that need to run three-phase AC water pumps.
SP2 helps solve a common field problem: the pump motor is three-phase, but the project site only has single-phase power or solar input available.
It is best for retrofit projects where replacing the pump would be costly, provided the inverter is sized from real motor current and starting conditions.
View SP2
SP3 220V Three Phase
For commercial 220V three-phase pumping systems and stronger pump loads.
SP3 fits buyers who need the efficiency and stability of a three-phase motor but still work within 220V local pump supply and service conditions.
It is often chosen for farms, orchards, and water transfer systems where daily running hours and pump protection matter more than the lowest device cost.
View SP3
SP4 380V Three Phase
For deep wells, large irrigation, municipal water, and industrial pump systems.
SP4 is the main path for higher-power pump motors, long lift heights, stronger flow requirements, and professional EPC water projects.
For this range, SolarSeeker usually recommends checking PV string design, cabinet protection, surge risk, heat dissipation, and commissioning access before quotation.
View SP4Complete System
Not every buyer only needs an inverter
A complete solar water pumping system may include panels, solar pump inverter, PV pump controller, submersible pump, control cabinet, sensors, wiring, and accessories. SolarSeeker helps match the product set before shipment.
SP5 PV Pump Controller and SP6 Submersible Pump Controller
Use pump controllers when the project needs dedicated pump control, MPPT operation, submersible pump protection, and simpler field wiring.
SP5 is positioned for PV pump control where the installer wants a compact controller path. SP6 is positioned for submersible pump protection and well applications where dry-run risk, water level changes, and long daily operation need careful handling.
For repeat dealer projects, controllers help reduce field mistakes because the wiring logic, protection behavior, and troubleshooting process can be kept consistent across many pump sites.
Submersible Well Water Pump
Select pumps by well depth, head, flow, voltage, daily water demand, and whether the site is for irrigation, livestock water, or remote supply.
The pump body should not be selected only by kW. A 2.2kW pump for shallow irrigation and a 2.2kW pump for a deep borehole can require different head, impeller design, cable length, and PV array planning.
SolarSeeker can help compare pump curve, site water source, daily flow target, and inverter or controller selection before the buyer commits to stock or project procurement.
Choose well pumpsSolar Pump Cabinet
For harsh environments, OEM projects, IP-rated wiring, protection, switching, and complete control cabinet integration.
A cabinet is not just a metal box. It can include DC and AC protection, terminal organization, cooling space, operation labels, emergency stop, and installer-friendly wiring layout.
This is important for desert, livestock, and remote agricultural sites where dust, heat, rain, and uneven maintenance skills can affect long-term system reliability.
View cabinet optionsSolar Powered Well Pump Kits
Use a complete kit when the buyer wants the panel, inverter or controller, pump, accessories, and sizing support matched together.
Kits are helpful when the buyer is building a repeatable solution for remote wells, small farms, villages, or dealer sales because fewer components need to be sourced separately.
SolarSeeker can recommend panel power, pump size, controller or inverter path, cable accessories, and a basic installation checklist from the project data provided.

Procurement Notes
What B2B buyers should confirm before choosing a solar pump product
A solar pump quotation is more accurate when the product path is selected from real site data. The same pump power can need different inverters, controllers, PV array sizes, and cabinet protection depending on voltage, water source, climate, and daily water demand.
Start from pump voltage, phase, and rated current
Do not select a solar water pump inverter only by pump kW. The motor nameplate voltage, phase, rated current, frequency, and service factor decide whether the buyer should choose 220V, 380V, or single-to-three-phase products.
This is especially important for distributors who serve several markets. A product that fits a 220V irrigation pump in the Philippines may not fit a 380V deep-well project in Africa or a phase-conversion retrofit in a remote farm.
Match flow, head, and daily water target
A correct product choice depends on hydraulic demand, not only electrical data. Well depth, total dynamic head, pipe distance, outlet pressure, target flow, and daily water volume all affect pump selection and PV sizing.
For irrigation, the buyer should also consider seasonal water demand and operating hours. For livestock watering or community water supply, stable output and protection against dry running may matter more than peak flow.
Size the PV array for real sunlight conditions
Panel power should be matched to pump load, inverter input range, local sunlight hours, temperature, and whether the system needs strong morning or afternoon operation. A low panel ratio can make the pump start late and stop early.
For cloudy or humid areas, buyers may need extra PV capacity to improve daily water output. For desert and high-temperature locations, heat, dust, and cable voltage drop should be included in the selection discussion.
Plan cabinet, protection, and after-sales support early
For EPC and OEM projects, cabinet layout, surge protection, wiring labels, enclosure rating, and maintenance access should be discussed before mass procurement. This reduces installation variation across different teams.
SolarSeeker can support model recommendation, quotation checklist, wiring guidance, and project documentation, which helps buyers reduce selection mistakes before the products reach the installation site.

FAQ
Solar water pump inverter and product system FAQ
Is this page only for solar pump inverters?
This page uses solar water pump inverter as the main topic, but it also works as the product entry for SolarSeeker solar pump products. Buyers can enter inverter categories, pump controllers, submersible pumps, solar pump cabinets, and complete solar powered well pump kits from here.
What is the difference between a solar pump inverter and a solar pump controller?
A solar pump inverter converts solar DC input into AC output and controls pump speed, voltage, frequency, MPPT, and protection. A solar pump controller can be simpler and is often used for dedicated pump control and protection. SolarSeeker offers both inverter and controller product paths.
How do I choose between 220V, 380V, and single-to-three-phase products?
Choose according to the pump motor nameplate. 220V products fit small to medium systems, 380V products fit deep-well and industrial systems, and single-to-three-phase products fit sites where a single-phase supply or PV input must drive a three-phase pump.
What size solar panel do I need for a 2.2kW pump?
As a first estimate, a 2.2kW pump often needs about 3kW to 3.5kW of PV panel capacity for stable daytime operation. The exact panel size depends on pump rated current, inverter input range, local sunlight hours, water head, daily water demand, and whether the buyer wants better output in cloudy or low-sun periods.
Can solar pump systems work on cloudy days?
Yes, solar pump systems can work on cloudy days if the solar input is still enough for the inverter or controller to run the pump. Water output will usually be lower than on clear days, so cloudy regions may need extra PV capacity, a storage tank, hybrid grid input, or a backup plan for critical water supply.
What is the warranty for SolarSeeker solar pump inverters?
SolarSeeker provides warranty and after-sales support for solar pump inverters, controllers, cabinets, and matched system products. The exact warranty period and coverage should be confirmed in the quotation because it can depend on product model, order terms, installation environment, and OEM requirements.
Can SolarSeeker help select the pump, cabinet, and complete kit?
Yes. Send pump power, voltage, rated current, well depth, flow and head target, application, and country. SolarSeeker can recommend the inverter, controller, submersible well water pump, solar pump cabinet, or complete solar powered well pump kit.
Which buyers is this product entry page for?
