SP1 Solar Pump Inverter

SP1 220V Single Phase Solar Pump Inverter for Small Wells and Farms

SP1 is a 220V single phase solar pump inverter for small wells, farm irrigation, livestock water, and dealer-ready pump kits. It is built for installers who need fast setup, fewer parameters, and stable pumping when sunlight changes during the day.

Choose Your SP1 Model

SP1 covers 0.4kW to 5.5kW 220V single phase pumps

Match the inverter to the pump nameplate first. If the pump runs for long hours, the well is deep, or the site is hot, send the nameplate to SolarSeeker before shipment so our engineer can confirm the safe model.

30-Second First Check

Use the quick SP1 sizing calculator before you send the pump nameplate

This calculator gives a first recommendation from pump power and panel wattage. Final selection should still be confirmed with pump current, head, flow, cable distance, and project country.

Recommended System

Select pump power and panel wattage, then calculate a first SP1 model recommendation.

Why SP1 Is Easier to Use

Less parameter work for small pump installers

Small solar pumping projects often fail because the drive is too complicated for the site. SP1 keeps the operation interface simple, reducing the number of complex parameters that installers need to touch during normal commissioning.

 

Simplified setup

For common 220V single phase pumps, the installer can focus on pump nameplate matching, wiring, and water source checks instead of working through long parameter menus.

 

Start waiting function

SP1 waits until solar energy is enough before starting the pump. This helps reduce repeated morning start-stop cycles when sunlight is still weak.

 

50 deg C operation

SP1 is designed for hot field sites, pump rooms, and dry-season irrigation areas where ambient temperature can be higher than a normal indoor installation.

Small Pump Applications

Where SP1 fits best

SP1 is the practical choice when the project uses a 220V single phase pump and the buyer wants a simple solar water pumping system without batteries. It is especially suitable for distributors who need a repeatable model for common small pump projects.

 

Residential and village wells

Use SP1 for small well water supply where daytime pumping fills a tank for later use.

 

Small farm irrigation

Match SP1 with 220V single phase irrigation pumps for vegetable plots, orchards, and livestock water.

 

Dealer-ready pump kits

SP1 can be packaged with panels, pump, cables, and protection parts for local pump dealers.

Before You Order

When SP1 is the right choice, and when it is not

The fastest way to avoid wrong selection is to confirm the pump phase, voltage, and power first. SP1 is for 220V single phase pumps. Other SP models cover three phase and higher-power projects.

Choose SP1 when

  •  The pump nameplate says 220V single phase.
  •  The project is a small well, farm, garden, or livestock water system.
  •  The installer needs a simple solar pump inverter with fewer settings.
  •  The buyer wants daytime direct solar pumping without batteries.

Choose another model when

  •  Use SP2 if the site needs single phase input to three phase output.
  •  Use SP3 if the pump is 220V three phase.
  •  Use SP4 for 380V three phase or larger projects.
  •  Use SP5 when input or output voltage needs customization.

Technical Checklist

SP1 functions that matter in the field

SP1 includes the common solar pump inverter functions buyers expect, but the product page should focus on the things that reduce field risk: correct pump matching, stable startup, heat tolerance, and simple support.

MPPT solar pumping

Tracks solar input and adjusts pump operation as sunlight changes.

Pump protection

Includes over-current, over-voltage, dry-run, and over-temperature protection.

Weak-sun startup logic

Start waiting helps avoid repeated starts when PV power is not yet enough.

Installer support

SolarSeeker can check the pump nameplate and PV array before order confirmation.

Selection Data

What to send for an SP1 recommendation

A pump nameplate photo is the best start. If you also send the site data below, SolarSeeker can confirm the SP1 model, PV array suggestion, and quotation checklist more quickly.

Pump nameplate

kW or HP, rated current, voltage, phase, frequency.

Water requirement

Total head, flow, well depth, tank height.

PV array plan

Panel wattage, quantity, string plan if available.

Installation site

Country, ambient temperature, enclosure or cabinet plan.

FAQ

SP1 220V single phase solar pump inverter FAQ

Can SP1 run a three phase pump?

No. SP1 is for 220V single phase pumps. If the pump is three phase, choose SP2 for phase conversion or SP3 for a 220V three phase solar pump inverter.

What size SP1 model do I need for a 2.2kW pump?

For a normal 2.2kW 220V single phase pump, SP1004 is the first model to check. If the rated current is high, the cable is long, or the pump starts under heavy load, send the nameplate so SolarSeeker can confirm whether a larger model is safer.

Does SP1 start when sunlight is weak?

SP1 includes a start waiting function. Instead of repeatedly trying to start when solar energy is too low, it waits until there is enough input power, which helps reduce stress on the pump and inverter.

Is SP1 suitable for outdoor installation?

SP1 can be used in field pumping projects, but the final enclosure should match the site. For rain, dust, direct sun, or unattended outdoor use, SolarSeeker can recommend a cabinet or a protected installation method.

What information should I send for model selection?

Send a pump nameplate photo, total head, required flow, well depth, cable distance, solar panel wattage, project country, and whether the inverter will be installed indoors, in a cabinet, or outdoors.

Before Quotation

Send These Details Before Quotation

SP1 is selected from a real 220V single phase pump nameplate. A photo is better than a typed model number because it shows voltage, current and frequency together.

Check whether SP1 fits the pump before ordering

Reduce wrong selection for small wells and farm kits

Help dealers prepare repeatable 220V single phase packages

SP1 pump nameplate

Send a clear photo showing 220V single phase, kW or HP, rated current and frequency.

Well or water source

Share well depth, water level, tank height, pipe distance, flow target and daily water demand.

Panel data

Panel wattage, Voc, Vmp and quantity help us check SP1 DC input and MPPT matching.

Kit or inverter only

Tell us if you need only SP1, or also pump, panels, sensors, cables and accessories.

Field environment

Small wells can still face rain, dust, heat and humidity. Tell us where the inverter will be installed.

Dealer or project order

Sample, retail package, distributor stock or farm project orders need different quotation details.

Simple message format: SP1 pump nameplate + well depth + flow target + panel data + kit scope + quantity. If some data is missing, send what you have first and SolarSeeker can help check the rest.
