Features

Built to simplify your solar pump system

High integration

DC breaker, fuse, surge protection and bus-bar inside. No combiner box needed.

IP66 protection

Dust and waterproof. Install directly below the PV modules, with physical anti-theft.

Efficient MPPT

99.99% MPPT, max DC input 900 V. Starts earlier and stops later for more water.

Built-in booster

Starts at low voltage, so you need fewer solar panels (below 4 kW, including 4 kW).

Replace the combiner box

A traditional inverter needs a separate combiner box with breaker, fuse and surge protection. The controller builds it all in, with IP66 protection that significantly reduces damage from moisture, dust and insects.

Hybrid mode and auto-switching

In hybrid mode the controller uses solar and grid (or generator) energy at the same time. The stronger the sunlight, the less AC energy is used. With auto-switching, it monitors PV voltage and connects AC power only when the voltage falls below your set threshold.

Questions

Common questions.

Is the INVT solar pump controller the same as a solar pump VFD or inverter?

Yes, in everyday use. The INVT SP100 takes DC from the solar panels and gives variable-frequency AC (0 to 400 Hz) to the pump motor, with MPPT to get the most power from the sun. That is why it is also sold as a solar pump inverter or solar pump VFD.

Do you have an AC and DC hybrid solar pump controller?

Yes. The AC&DC versions (2, 4, 2-T and 4-T) run on solar power and switch to grid or generator power when the sun is low. The D versions (D2, D4) are solar only.

What is the price of a 5 HP or 7.5 HP solar pump controller?

Prices are not shown on the website. A 5 HP pump (about 3.7 kW) uses the 4 kW controller and a 7.5 HP pump (about 5.6 kW) uses the 7.5 kW controller. Message RS Corporation on WhatsApp at +91 77966 61999 for a quote.

Can I run a 3 phase pump with the INVT solar pump controller?

Yes. The SP100 range has 220 V class (single or three phase) and 380 V class (three phase) versions from 0.75 to 22 kW. Choose the class that matches your pump motor.

How many solar panels do I need for the controller?

It depends on the model. The catalog gives a recommended array in 540 W modules, for example 14 modules in series for a 4 kW DC controller. Open the models and ratings section or ask the chat for your kW.

Does the controller come with support?

Yes. RS Corporation gives lifetime free support for the solar pump controller.

Which controller power do I need for my pump?

Choose a controller with a rating (kW) equal to or higher than your pump motor. 1 HP is about 0.746 kW, so a 5 HP pump (about 3.7 kW) fits the 4 kW controller, and a 7.5 HP pump (about 5.6 kW) fits the 7.5 kW controller. The chat on this page can suggest a model if you type your pump size.

What is the difference between the D, 2/4 and -T versions?

D2 and D4 run on solar only (DC input). The versions marked 2 and 4 are AC and DC: they also run on grid or generator power when the sun is low. The -T versions add a built-in boost module and start at a lower DC voltage (100 V instead of 200 to 300 V). 2 means a 220 V class and 4 a 380 V class.

What is a solar pump controller (solar pump inverter)?

A solar pump controller, also called a solar pump inverter or solar pump drive, runs your water pump directly from your solar panels. It manages the power, starts and stops the pump automatically and protects it from faults such as dry run, over-load and over-heat.

Can I run the pump on grid or generator power too?

Yes. The AC and DC versions support hybrid operation. When sunlight is low, the controller can use grid or generator power automatically.

Is the controller suitable for outdoor use?

Yes. It has IP66 protection, which means it is dust and waterproof, and can be installed right below the solar panels.

Can I monitor the pump from my phone?

Yes. With the 4G or WiFi module you can watch the pump system from your phone or computer, including fault alerts and history.

Which areas does RS Corporation supply?

We are based in Nashik, Maharashtra, and supply businesses and farms across India.
