SP5 PV Pump Controller
Customized PV Pump Controller for Existing Solar Pump Systems
SolarSeeker builds SP5 around your customer’s original pump system, including voltage, phase, PV input, AC output, control terminals, protection logic, enclosure, and OEM branding.
This page is for distributors, EPC contractors, pump dealers, and OEM partners who need a controller that matches an existing system instead of forcing every project into one standard catalog model.

Customization Scope
What can SolarSeeker customize on SP5?
SP5 is not positioned as one fixed controller. It is a configurable PV pump controller platform for buyers who already know their pump, panel, site, or market requirements.
Voltage & Phase
220V, 380V, regional voltage requests, single phase, three phase, and project-specific input/output matching.
PV Input Range
PV string voltage, MPPT range, panel series count, DC protection, and cloudy-day startup behavior.
Pump Output
Output current, pump phase, pump power, overload margin, soft start, frequency range, and motor protection.
I/O Logic
Float switch, tank full, dry-run, remote start, alarm output, sensor input, and RS485 communication.
Protection Settings
Under voltage, over voltage, dry-run threshold, restart delay, fault memory, and site-specific alarm logic.
Enclosure & Cabinet
Indoor controller, cabinet integration, outdoor protection, cooling, cable entry, and project wiring layout.
OEM Branding
Private label, product label, packaging, user manual, datasheet, wiring diagram, and repeated configuration.
Regional Projects
Configuration support for Southeast Asia, Africa, Middle East, South America, and China field projects.
Decision Guide
When SP5 is better than a standard model page
Use SP5 when the buyer needs engineering adaptation. Use SP1-SP4 when the buyer only needs a standard voltage and phase path.
Existing System Replacement
The old controller failed, but the pump, panels, wiring, and site layout should remain.
Non-Standard Voltage
The project does not fit a simple 220V or 380V catalog controller.
OEM Product Line
You need repeatable private-label controller settings for dealers or pump kits.
Not for Simple Catalog Buying
If the project clearly needs SP1, SP2, SP3, or SP4, use the model page first.
Engineering Workflow
How SolarSeeker customizes a PV pump controller
The fastest way to quote SP5 is to send the original system data. SolarSeeker engineers then map the controller to the pump, panels, wiring, and customer market.
Send Original Data
Old controller label, pump nameplate, solar panel data, wiring photo, and required country voltage.
Engineer Matching
SolarSeeker checks PV input, output current, phase, frequency, protection, and terminal logic.
Confirm Configuration
You receive a suggested SP5 configuration, wiring note, optional cabinet plan, and OEM requirements list.
Sample or Batch
Start with sample verification, then move to repeat orders, private label, and market-specific packaging.
Send This Data
SP5 custom controller checklist
A complete inquiry lets SolarSeeker quote faster and prevents voltage, phase, or wiring mismatch after delivery.
Send Checklist to Engineer| Data Needed | What to Send | Why It Matters |
|---|---|---|
| Old Controller | Nameplate photo, model, wiring terminals | Helps match input/output and replacement dimensions |
| Pump Motor | kW/HP, voltage, phase, current, frequency | Prevents overload and phase mismatch |
| Solar Array | Panel wattage, Voc, Vmp, string count | Confirms PV input and MPPT range |
| Control Inputs | Float switch, tank sensor, remote switch, RS485 | Defines terminal layout and logic |
| Environment | Indoor, outdoor, desert, coastal, humidity, dust | Determines enclosure or cabinet need |
| OEM Needs | Logo, label, manual, packing, market language | Supports repeatable private-label supply |
Fastest Quotation Path
Send the old controller label and pump nameplate
If you are replacing another brand or building an OEM controller line, one photo of the original controller plus pump data is usually enough for SolarSeeker to start matching the SP5 configuration.
Original Video Preserved
SP5 setup and wiring video
Use the video for basic wiring understanding. For customized SP5 projects, SolarSeeker provides the final wiring note based on your voltage, phase, input/output, and terminal logic.
Check PV Input
Confirm panel string voltage before wiring.
Match Pump Output
Confirm phase, voltage, current, and frequency.
Set Protection
Dry-run, tank full, restart, and alarm logic.
Run Test
Check flow, current, and fault display.
Fault Diagnosis
Simple field diagnosis for customized systems
The original fault display images are preserved. These visual codes help distributors and field installers explain problems without complex manuals.
Low Frequency Fault
Output frequency below safe operating range.
Check: solar input, startup power, and panel wiring.
Dry Run Protection
Pump current is below dry-run threshold.
Check: water source, pump submersion, and sensor status.
Under Voltage Fault
DC or AC voltage is below configured threshold.
Check: PV string count, cable loss, and input voltage.
Over Voltage Fault
Input voltage exceeds the configured safe range.
Check: panel series count and controller voltage rating.
Water Tank Full
Float switch has stopped pumping to prevent overflow.
Status: auto pause until water level changes.
Water Well Empty
Water source signal indicates no available water.
Check: well level, sensor wiring, and restart delay.
Product Path
SP5 vs standard SolarSeeker models
This table helps visitors choose the right internal link instead of treating every controller page as the same product.
| Path | Best For | Use When | Link |
|---|---|---|---|
| SP1 | 220V single phase pump | Small wells and farms need a standard model | SP1 page |
| SP2 | Single to three phase conversion | Site has single-phase supply but uses three-phase pump | SP2 page |
| SP3 | 220V three phase pump | Commercial 220V three-phase system | SP3 page |
| SP4 | 380V three phase pump | Industrial high-power standard system | SP4 page |
| SP5 | Customized PV pump controller | Need custom voltage, phase, I/O, firmware, enclosure, or OEM branding | Ask custom quote |

Customized PV pump controller FAQ
Can SolarSeeker customize SP5 for my existing pump system?
Yes. Send the old controller label, pump nameplate, panel data, wiring photo, and required voltage. SolarSeeker checks whether SP5 can match the original system’s voltage, phase, input, output, and control logic.
What can be customized on the SP5 PV pump controller?
Typical customization includes voltage, phase, PV input range, output current, protection parameters, I/O terminals, float switch logic, RS485 communication, enclosure, label, manual, packaging, and OEM branding.
Is SP5 only for 220V and 380V systems?
220V and 380V are common configurations, but SP5 is intended for custom projects. For regional voltage or phase requirements, send the target market standard and pump data for engineering review.
Can I use SP5 for OEM solar pump kits?
Yes. SP5 is suitable for OEM pump kits when distributors need repeatable controller settings, private labels, custom manuals, and matched wiring diagrams for their own pump or kit line.
How is SP5 different from SP1, SP2, SP3, and SP4?
SP1-SP4 are standard model paths for clear voltage and phase choices. SP5 is the custom controller path when the project needs non-standard configuration, OEM requirements, or replacement of an existing controller system.
What information should I send for an SP5 quotation?
Send pump power, voltage, phase, rated current, PV panel wattage, panel string plan, old controller photo, wiring terminal photo, control inputs, installation environment, country, and OEM branding requirements if needed.
Next Step
Need a controller that matches your customer’s original system?
Send the pump nameplate, old controller label, PV panel data, wiring photo, and OEM request. SolarSeeker will review whether SP5 is the right customized PV pump controller path.
