SP5 / Custom PV Pump Controller
Custom PV Pump Controller for OEM Solar Pump Systems
SolarSeeker builds SP5 PV pump controllers around your required input voltage, output voltage, pump type, I/O logic, enclosure, branding and project wiring requirements.
For OEM partners, pump dealers, cabinet builders and replacement projects, SP5 is the flexible controller path when a standard inverter model is not enough.
Custom voltage
input and output matching
OEM support
label, manual and packing
Control logic
sensors, terminals and protection
Sample to batch
engineering check before production
When SP5 Fits
Use SP5 when the project does not fit a standard inverter model
SP1, SP2, SP3 and SP4 are standard solar pump inverter paths. SP5 is different: it is for projects where the controller must be adapted around a pump, an existing system, a cabinet design or an OEM product plan.
Replacement Projects
When a customer wants to replace an old controller but keep the pump, wiring habit or site logic.
Non-Standard Voltage
When input or output voltage requirements need engineering confirmation instead of catalog selection.
OEM Product Line
When a pump brand, distributor or system integrator needs private label, manual and repeatable packing.
Cabinet Builds
When the controller must fit a cabinet wiring plan, sensor input design or protection layout.
Custom Scope
What SolarSeeker can customize on SP5
Tell us what the pump and market require. Our team checks the electrical boundary, control logic and production feasibility before confirming the final controller plan.
Ask for OEM QuoteInput voltage and PV range
PV input, AC backup needs and operating voltage range can be reviewed according to the pump system.
Output voltage and phase
Output matching is checked against pump voltage, phase, rated current and local market requirements.
Pump protection logic
Dry run, over voltage, under voltage, overload, tank full and well empty logic can be configured for the project.
Terminals and I/O signals
Sensor inputs, external control, water level signals and cabinet wiring requirements can be planned before production.
Enclosure and cabinet integration
Controller installation can be matched to an enclosure, pump cabinet or OEM system package.
Branding and documents
OEM label, keypad naming, manual, carton label and packing details can be prepared for approved orders.
OEM Process
From custom requirement to repeatable controller supply
Good customization starts with real pump data. We confirm the technical boundary first, then move into sample, label and batch production details.
Step 1
Send data
Pump nameplate, old controller label, wiring photos and target market.
Step 2
Check feasibility
Voltage, current, PV range, phase and protection logic are reviewed.
Step 3
Confirm design
Controller configuration, label, manual and packing plan are aligned.
Step 4
Sample order
Pilot units help verify wiring, pump response and field use.
Step 5
Batch supply
Approved requirements can move into repeatable OEM production.
Before Quotation
Share these details before we promise a custom controller
Custom work should not be guessed from pump power alone. The more complete the data, the faster we can judge whether SP5 is the right path.
Pump voltage, phase, power and rated current
Required input and output voltage
Old controller label or wiring photo
Water level sensor and I/O logic
Enclosure, cabinet or mounting needs
OEM quantity, label and market plan
What we will check
Electrical match
Input, output, current, phase and PV working range.
Control logic
Water level, external signals, protection behavior and fault display.
OEM production fit
Label, manual, packing, sample plan and repeat order stability.
Model Boundary
SP5 is for custom controller work, not simple catalog buying
If the pump fits a standard voltage and phase path, a standard SP inverter is usually faster. Choose SP5 when the controller itself must be adapted.
| Need | Better path | Reason |
|---|---|---|
| Standard 220V or 380V AC pump | SP1-SP4 inverter range | Faster selection, known voltage path and standard inverter supply. |
| Custom input or output requirement | SP5 PV pump controller | Engineering review is needed before confirming controller configuration. |
| Private label pump kit | SP5 OEM controller path | Branding, documentation and repeatable package details matter. |
| Protected submersible controller project | SP6 IP55 controller path | Use when enclosure protection and submersible controller positioning are the main issue. |
Who Uses SP5
SP5 is built for buyers with repeated or unusual controller needs
The strongest fit is not a one-time catalog order. It is a project or product line where a tailored controller helps the buyer reduce local adaptation work.
Pump manufacturers
For a controller matched to a branded pump series or pump kit.
Distributors
For repeat stock with local market labels, documentation and wiring habits.
Irrigation contractors
For projects with water level automation, cabinet integration or non-standard pump data.
EPC and cabinet builders
For controller selection that must fit wiring, protection and commissioning requirements.

FAQ
Custom PV pump controller FAQ
Can SolarSeeker customize the input and output voltage?
Yes, SP5 is used for custom PV pump controller work where input and output requirements need engineering review. Send the pump nameplate, voltage target and site wiring details first.
Can SP5 be supplied with my own brand?
OEM branding can be discussed for qualified orders, including label, manual, carton label and packing details. The final plan depends on quantity and technical requirements.
Is SP5 better than SP1-SP4?
Not always. SP1-SP4 are better when the pump fits a standard inverter path. SP5 is better when the controller must be customized for voltage, logic, replacement, cabinet integration or OEM supply.
Can SolarSeeker copy an old controller exactly?
We can review the old controller label, wiring and function requirements, then judge what can be matched or redesigned. Exact copying is not promised before engineering confirmation.
What is the first step for an OEM SP5 project?
Send the pump nameplate, target voltage, control logic, enclosure needs, branding requirements and expected quantity. SolarSeeker will check feasibility before quoting.
Before Quotation
Send These Details Before Quotation
SP5 is mainly for custom PV pump controller work. Send the repeated requirement clearly before quotation so SolarSeeker can judge feasibility and production path.
Clarify custom voltage, I/O logic or OEM requirements
Check whether the project is repeatable before development
Avoid treating SP5 like a normal off-the-shelf inverter
Pump and system data
Send pump voltage, phase, power, current, application and working condition.
Custom function
Explain custom voltage, I/O, control logic, display, menu, communication or protection requirements.
OEM label details
Logo, housing label, manual language, packaging and repeated order plan affect quotation.
Enclosure and wiring
Board, controller box, cabinet layout, cable entry and protection level should be confirmed early.
PV input plan
Panel string data and backup power requirements help us check the controller range.
Repeat order scope
Custom controller work is stronger when quantity, forecast and buyer role are clear.
Simple message format: pump data + custom function + OEM label + enclosure/wiring + PV input + order forecast. If some data is missing, send what you have first and SolarSeeker can help check the rest.
Need a PV pump controller built for your pump or brand?
Send your pump nameplate, old controller label, voltage target, I/O logic and OEM requirements. SolarSeeker will check whether SP5 can be configured for the project.
