INVT 2.2kW Single Phase Solar Pump Inverter

The INVT 2.2kW Single Phase Solar Pump Inverter, model SP100-2R2-2-T-6-S, is an AC/DC solar pump controller for compatible 220V borehole, irrigation, and surface-pump systems. It supplies up to 2.2kW rated output and uses solar PV energy to operate a pump without a battery bank or separate MPPT charge controller.

The model supports compatible single-phase and three-phase pump motors. Confirm the pump voltage, phase, rated current, motor type, cable length, and starting requirements before ordering. A 2.2kW motor rating alone does not confirm compatibility.

INVT 2.2kW Solar Pump Inverter Key Benefits

• Built-in voltage booster: Supports lower-voltage starting and helps extend the daily solar pumping period.
• Integrated MPPT control: Adjusts the pump operating frequency according to available PV power.
• AC and DC input: Supports solar PV input and a compatible 220V to 240V class AC source.
• Battery-free operation: Runs a correctly designed pump system directly from solar panels.
• IP66 enclosure: Provides dust and water-jet protection for suitable wall-mounted outdoor installations.
• Integrated pump protection: Includes low-voltage, overvoltage, overload, dry-run, overheat, surge, full-water, and empty-water protection functions.

Recommended Solar Panel Configuration

INVT lists five 540W solar panels in one series string as the recommended example for this model when each panel has an open-circuit voltage of approximately 49V ±1V. This provides a nominal array rating of 2700W.

Do not select panels from wattage alone. Confirm each panel’s Voc, Vmp, current rating, and temperature coefficient. The complete series string must remain below the inverter’s 450V maximum DC input under the coldest expected site temperature and operate within the recommended 100V to 400V range.

Browse available solar panels, then confirm the final string design before ordering.

AC Backup and Operating Modes

The SP100 supports solar PV and AC input. Depending on the selected operating mode, available AC power may supplement or replace PV power when solar energy drops.

AC operation requires a live grid or generator source, suitable protection equipment, correct wiring, parameter configuration, and any switching equipment required by the installation design. Load shedding does not provide AC backup unless a generator or another independent AC source is running.

Applications in South Africa

• Borehole pumps for farms and smallholdings.
• Livestock water systems.
• Crop and garden irrigation.
• Water transfer between reservoirs or tanks.
• Surface and submersible pump systems with compatible motor ratings.
• Sites seeking daytime solar pumping without battery storage.

Installation and Compatibility

A qualified installer should verify the pump motor plate, output phase, current limits, PV string voltage, cable length, earthing, isolators, surge protection, and AC backup design. Install and commission the inverter according to the current INVT manual.

The IP66 rating supports suitable outdoor installation, but the enclosure should not be submerged or installed in a flood-prone position. Follow the required mounting clearances and protect the wiring and connections from mechanical damage.

Frequently Asked Questions

Does this inverter work with a single-phase borehole pump?

It supports compatible 220V single-phase pump motors with output current requirements within the inverter’s 14A single-phase rating. Confirm the motor plate and pump requirements before ordering.

Does the inverter also support three-phase pumps?

The model provides a three-phase output-current rating of 10A. Confirm the exact pump voltage, phase, current, and motor type with the installer.

Does the system require batteries?

No battery bank is required for normal PV-direct pumping. Water storage in a tank often provides the practical storage function for daytime solar pumping systems.

How many solar panels are recommended?

INVT’s reference configuration uses five 540W panels in one series string where each panel has a Voc of approximately 49V ±1V. Different panel models require a fresh voltage and current calculation.

Does the inverter automatically switch to generator power?

The inverter supports AC/DC operating modes and configurable source control. Correct automatic operation depends on the system wiring, parameter setup, available AC source, and any required switching equipment.

Is the inverter suitable for outdoor installation?

The enclosure has an IP66 rating and supports suitable wall-mounted outdoor installation. It is not rated for submersion or installation in flood-prone locations.
