Solar Pump Controllers
Solar Pump Controller for Custom PV Pump and IP55 Submersible Pump Projects
SolarSeeker supplies two controller choices for projects that do not start with a standard inverter model. SP5 is built around custom voltage, OEM branding and special control logic. SP6 is an IP55 submersible pump controller for dusty, humid and remote pump sites.
For pump dealers, EPC contractors, irrigation installers and OEM partners, the right choice depends on the pump nameplate, input and output voltage, installation environment and how much customization the order needs.

Two Controller Choices
Choose by customization need and installation environment
A pump controller should be selected from the real job conditions. SP5 is for custom electrical and OEM requirements. SP6 is for submersible pump sites that need an IP55 controller body and easier field service.
SP5 / PV Pump Controller
For custom voltage, OEM labels and special control logic
Use SP5 when the controller has to match a non-standard input or output voltage, an existing pump system, a cabinet wiring plan, or a private-label product line.
- Input and output voltage customization
- OEM label, manual and packing support
- Sensor, terminal and protection logic review
SP6 / IP55 Controller
For submersible pump sites with dust, humidity and service access needs
Use SP6 when a standard indoor controller feels too exposed for the pump location, but the project does not require a full outdoor cabinet from the start.
- IP55 controller enclosure for rougher pump sites
- Used with submersible pumps in wells, farms and remote water supply
- For IP65 outdoor protection, match it with a solar pump cabinet
Fast Selection
Match the controller to the job before asking for price
A short check at the beginning prevents the common mistake: choosing by pump power only, then finding out the voltage, environment or wiring logic does not match.
| Project need | Choose | Why it fits | What to send us |
|---|---|---|---|
| Custom input or output voltage | SP5 | The controller can be reviewed around the required voltage boundary instead of forcing a catalog model. | Pump nameplate, target input/output voltage, old controller label |
| Private-label pump system or OEM order | SP5 | Branding, documents, packing and repeatable configuration can be discussed before sample production. | Target market, order plan, label requirement, function list |
| Submersible pump in a dusty or humid field site | SP6 | The IP55 controller body is better suited to rougher pump rooms, well sites and remote installations. | Pump nameplate, site photos, cable entry and mounting location |
| Direct rain, public access or larger protection wiring | Solar pump cabinet | A cabinet gives more room for breakers, surge protection, lockable access and IP65 system protection when required. | System wiring plan, site exposure, cabinet size and protection needs |
| Standard 220V, 380V or single-to-three-phase pump drive | Solar pump inverter range | SP1-SP4 are faster choices when the pump follows a standard voltage and phase requirement. | Pump voltage, phase, kW, rated current and PV module data |
Avoid Wrong Matching
Controller, inverter and charge controller are not the same thing
Many inquiries use these words loosely. Before quoting, SolarSeeker checks whether the buyer needs a pump drive, a customized controller, a protected cabinet or a complete solar well pump system.
Solar pump controller
Used here for SP5 and SP6 controller products, especially when customization or pump-site protection matters.
Solar pump inverter
Used for SP1-SP4, where the main job is driving a 220V, 380V or single-to-three-phase pump from PV power.
Solar charge controller
A battery charging device. It is not the right product when the goal is to run an AC pump motor directly.
Before Quotation
Send the pump and site details first
A correct controller recommendation depends on more than the pump power. The nameplate, PV array, water source and installation environment decide whether SP5, SP6, a cabinet or a standard inverter is the cleanest choice.
Send Project DetailsPump nameplate
Voltage, phase, kW or HP, rated current and frequency.
PV module data
Panel power, Voc, Vmp, quantity and planned string design.
Water requirement
Well depth, head, flow, pipe distance and daily water target.
Installation environment

FAQ
Common questions before choosing a solar pump controller
These are the checks we usually make before recommending SP5, SP6 or another SolarSeeker product.
What is a solar pump controller?
A solar pump controller manages how solar power runs a water pump and protects the pump system during operation. On SolarSeeker.tech, SP5 is the custom PV pump controller option, while SP6 is the IP55 submersible pump controller option.
Should I choose SP5 or SP6?
Choose SP5 when the project needs customized input voltage, output voltage, OEM branding or special control logic. Choose SP6 when the controller will be used with a submersible pump in a dusty, humid, coastal or remote site where IP55 protection is important.
Is SP6 IP55 or IP65?
SP6 is an IP55 submersible pump controller. If your project needs IP65 outdoor system protection, SolarSeeker can help match the controller with a suitable solar pump cabinet.
Is a solar pump controller the same as a solar pump inverter?
Not always. Many buyers use the words together, but SolarSeeker separates the product choices. SP1-SP4 are solar pump inverter models for standard pump drive selection. SP5 and SP6 are controller choices for custom PV pump work and IP55 submersible pump sites.
Can SP5 be customized for OEM orders?
Yes. SP5 can be discussed for input and output voltage customization, OEM label, manual, packing, control logic and cabinet integration. SolarSeeker will check the pump data and feasibility before confirming the final plan.
What information do you need for a quotation?
Please send the pump nameplate, required voltage, PV module data, well depth or head, flow target, site photos and any OEM or cabinet requirement. This lets SolarSeeker recommend SP5, SP6, a cabinet or a standard inverter without guessing.
Before Quotation
Send These Details Before Quotation
Controller projects need more than pump power. Send the control logic, enclosure, sensor and OEM requirements before SolarSeeker recommends SP5 or SP6.
Separate standard inverter needs from controller projects
Clarify sensor, enclosure and OEM logic early
Reduce custom quotation gaps before production
Pump and motor data
Send voltage, phase, power, rated current, pump type and application.
Control logic
Tell us if the controller needs tank level, dry-run, pressure, float switch or special I/O logic.
Enclosure requirement
Indoor board, IP55 controller, cabinet integration or outdoor protection changes the product path.
PV and power input
Panel data, DC input range, grid or generator backup plans should be clear before quotation.
OEM or label needs
Logo, label, menu language, wiring diagram, documentation and repeated order details affect production.
Order scope
Sample, custom development, distributor stock or EPC project order changes lead time and support.
Simple message format: pump data + control logic + enclosure need + PV input + OEM details + quantity. If some data is missing, send what you have first and SolarSeeker can help check the rest.
Not sure whether the project needs SP5, SP6 or a cabinet?
Send the pump nameplate and a few site photos. SolarSeeker will check the voltage, pump type, environment and customization needs before recommending a controller.
