Solar Pump Inverter Accessories for Well Pump Kits
SolarSeeker supplies optional accessories for solar pump inverters and solar powered well pump kits, including output reactors, 24V power boards, water level sensors, boosters, cooling fans and DC contactors.
For deep wells, long motor cables, tank filling, hot cabinets or repeat dealer orders, the right accessory list can reduce commissioning problems before the shipment leaves the factory.

OEM
dealer kit packing
Selection Logic
Add accessories when the site asks for more than basic pump running
A solar pump inverter can start and protect the pump by itself. Accessories become important when the cable is long, the water level changes often, the cabinet runs hot, or the buyer needs a repeatable package for installers.
Long Motor Cable
Deep wells and remote pump houses may need an output reactor to reduce stress between the inverter and motor.
Water Level Control
Float switches or level sensors help stop dry running and prevent tank overflow in unattended pumping systems.
Hot Cabinet Conditions
Fans and cabinet accessories help projects in high-temperature rooms, sealed panels or outdoor control boxes.
Dealer Stock Kits
Distributors can order common accessories with SP inverters to make local installation and after-sales work faster.
Accessory Options
Core accessories for solar pump inverter projects
Choose accessories according to motor distance, water source, control method and cabinet environment. SolarSeeker can match the list together with SP1, SP2, SP3, SP4, SP5 or SP6 orders.
Output Reactor
Used when the cable from the inverter to the pump motor is long or the site needs extra motor-side protection.
Best for deep wells and long cable runs
24V Power Board
Provides auxiliary power for low-voltage control devices, sensors or project-specific control circuits.
Best for external control and sensor wiring
Water Level Sensor
Helps control well-empty and tank-full signals so the solar pump system can run with fewer site visits.
Best for dry-run and tank filling control
Solar Booster
Used in selected PV pump systems when voltage support is needed for the chosen pump and controller setup.
Best for project-specific PV voltage matching
Cooling Fan
Supports cabinet heat dissipation when the inverter is installed in a control box or a high-temperature environment.
Best for cabinets, pump rooms and hot sites
DC Contactor
Used for PV-side control and protection requirements in selected solar pump cabinet or system packages.
Best for cabinet-built PV pump systems
Product Fit
Match accessories to the inverter or controller path
The accessory list changes with pump voltage, cable distance, control method and enclosure. Send the pump nameplate and site notes before ordering a mixed kit.
Send Pump Data| SolarSeeker path | Typical accessory need | Use when |
|---|---|---|
| SP1 / SP3 | Water level sensor, 24V board, reactor when cable is long | 220V wells, small irrigation, tank filling and dealer stock |
| SP2 | Reactor, sensor and basic control accessories | Single-phase site input with three-phase pump output |
| SP4 | Output reactor, DC contactor, cabinet fan and water level control | 380V deep wells, large irrigation and long cable systems |
| SP5 | Project-specific accessories based on custom input and output voltage | OEM control projects and non-standard pump matching |
| SP6 IP55 | Outdoor sensor and protection accessories selected by site condition | Protected submersible pump controller projects |
| IP65 Cabinet | Fan, contactor, wiring accessories, terminals and cabinet protection parts | Outdoor control boxes, EPC projects and assembled pump packages |
Common Combinations
Accessory packages we often check before quotation
The final list depends on the pump and site, but these combinations cover many solar well pump and irrigation projects.
Deep well with long motor cable
Solar pump inverter, output reactor, water level sensor and clear cable distance notes.
Check: pump voltage, rated current, cable length and well depth.
Tank filling system
Solar pump inverter, water level sensor, 24V power board and tank-full signal logic.
Check: tank control method, sensor type and pump start-stop expectation.
Cabinet-built PV pump system
Inverter or controller, DC contactor, cooling fan, cabinet wiring accessories and protection parts.
Check: cabinet size, outdoor rating, local temperature and wiring plan.
Dealer repeat-order kit
Common sensors, boards, fans, reactors and spare accessories packed with standard SP inverter orders.
Check: target pump range, local installer skill and after-sales stock plan.
Before Ordering
Send these details before we build the accessory list
A small accessory can be wrong if the pump data or site condition is missing. Share the basic project information first, and SolarSeeker will recommend a cleaner BOM.
Pump power, voltage, phase and current
Inverter or controller model
Cable distance from drive to pump
Well depth, tank and water level logic
Cabinet location and temperature
Dealer packing or OEM label needs
Fast accessory check
1. Send the nameplate photo
The pump label and inverter model decide most of the accessory boundary.
2. Confirm cable and water control
Long cables and water level signals are the most common reasons to add accessories.
3. Pack the right kit
We can ship accessories with the inverter, controller or cabinet package to reduce missing parts on site.

FAQ
Solar pump inverter accessories FAQ
Do I need an output reactor for every solar pump inverter?
No. An output reactor is usually considered when the motor cable is long, the well is deep, or the installation needs extra motor-side protection. Send the cable distance and pump current before choosing it.
When should I add a water level sensor?
Add a water level sensor when the pump must stop at low well level, stop when the tank is full, or run with limited manual supervision.
Can these accessories be packed with SP1, SP2, SP3 and SP4?
Yes. Accessories can be matched with SolarSeeker SP inverter orders according to pump voltage, phase, power, cable distance and site control requirements.
Are accessories available for SP5 and SP6 projects?
Yes. SP5 is often used for customized PV pump controller projects, while SP6 is an IP55 submersible pump controller path. Accessory selection depends on input/output voltage, enclosure, sensor needs and the pump system design.
Can accessories be installed inside a solar pump cabinet?
Many accessories can be integrated into a solar pump cabinet, including contactors, fans, wiring terminals and protection parts. Cabinet layout should be checked before production.
What information is needed for an accessory quotation?
Send the pump nameplate, inverter or controller model, cable distance, well and tank control method, cabinet location and whether the order is for one project or dealer stock.
Before Quotation
Send These Details Before Quotation
Accessory and kit quotations depend on what the buyer already has. Send the existing equipment list first so SolarSeeker can build the missing package.
Clarify whether the buyer needs accessories or a complete kit
Avoid missing sensors, reactors, boards, fans or protection parts
Help dealers build repeatable pump kit packages
Existing equipment
Tell us what you already have: pump, inverter, controller, panels, cabinet, cables or sensors.
Missing accessories
List output reactor, sensors, 24V board, booster, fan, DC contactor or other parts needed.
Pump and inverter data
Send pump nameplate and inverter/controller model so accessories can be matched correctly.
PV and wiring plan
Panel string, cable distance, cabinet layout and protection parts affect the accessory list.
Site condition
Dust, humidity, heat, rain and outdoor exposure decide enclosure and protection requirements.
Kit scope and quantity
Sample kit, dealer package, EPC project or OEM bundle quotations need different BOM details.
Simple message format: existing equipment + missing accessories + pump/inverter data + wiring plan + site condition + quantity. If some data is missing, send what you have first and SolarSeeker can help check the rest.
Need the accessory list before shipment?
Send the pump nameplate, inverter model, cable distance and water level control plan. SolarSeeker will check whether the project needs sensors, reactors, boards, fans, contactors or cabinet accessories.
