INVT Solar Pumps VSD Range

The INVT SP100 Solar Pump Inverter and GD100 Variable Speed Drive (VSD) range together form a flexible, high-efficiency

motor control platform designed to support both renewable energy water pumping applications and general industrial motor

control requirements. The SP100 enables direct solar-powered pumping without batteries, making it ideal for agricultural,

irrigation, and remote water systems, while the GD100 delivers reliable and energy-efficient motor speed control across

pumps, fans, compressors, conveyors, and general industrial machinery. Combined, these platforms provide a cost-effective

and scalable solution for both off-grid and grid-connected motor-driven systems.


KEY FEATURES

Dual Application Flexibility – Solar & Industrial Control

SP100 is optimised for photovoltaic water pumping, while GD100 provides robust general-purpose motor control

for industrial applications.


Built-In MPPT Solar Optimisation (SP100)

Maximises solar energy utilisation by continuously tracking the optimal power point of PV arrays for

efficient pump operation.


Advanced Motor Control Performance (GD100)

Supports V/F and sensorless vector control for precise torque, smooth operation, and improved motor efficiency.


Wide Input Voltage Compatibility.

SP100 supports flexible PV string configurations, while GD100 accommodates a wide range of industrial power

supply conditions.


Integrated Pump & Motor Protection Functions

Includes protection against dry-run, overload, over/under-voltage, phase loss, and motor overheating for

extended equipment lifespan.


Energy Efficiency Optimisation

Both platforms reduce energy consumption through intelligent load adaptation and high-efficiency drive algorithms.


Built-In PID Control Functionality (GD100)

Enables closed-loop control for pressure, flow, temperature, and other process-driven industrial applications.


Hybrid Operation Capability (SP100)

Supports solar-only or hybrid solar + AC input operation, ensuring continuous pumping when required.


Rugged Industrial-Grade Design

Engineered for harsh environments including high temperature, dust, humidity, and remote installations.


Simple Commissioning & Flexible Configuration

User-friendly parameter setup and adaptable control logic reduce installation time and simplify system integration.


Wide Application Coverage

Suitable for borehole pumping, irrigation systems, HVAC, water treatment plants, manufacturing equipment, and

general automation systems.


Stable & Reliable Long-Term Operation

Designed for continuous duty operation with strong protection architecture to ensure long service life and reduced

maintenance requirements.
