Power loss over distance

[sardarg]

river which is 5000 feet away

sir 5000 feet is approx 1.52kms. The current / voltage drop over insulated wire of such length will be significant. Power supply providers use bare metal conductors for lengths exceeding 200 ~300 meters, between PMTS.

Your inverter / panels will fail to drive the pump motor for such distance. Unless you invest heavily for overhead copper line feed.

Okay sir t

The setup is as follows: I have two installations running two tubewells of 15 HP. The panels are installed on roof and VFD alongwith motors are in a room underneath. For this third motor that i want to run 5000 away from these two installations, i can install the VFD near this new motor or near the panels.

[capsat]

which VFD/ inverter brand model you are using to convert Panel DC Voltage to AC 3 phase

[capsat]

I don't think there is a economical solution to your problem.
3 phase motor via VFD - while VFD input from panels is 5000 feet away,. The Frequency drop will not drive 3 phase motor (through Y delta) as mentioned by @nfssaad

[Hassan1991]

VFD should be installed near the motor.
Then you need to supply power to VFD.
As mentioned by members, wires are going to be very thick and expensive if you want to run motor 5000 feet away.
It's better if you installed separate independent unit near motor.
What do you say @capsat sir?

[capsat]

yes please that is a likely solution.
voltage from panels / amperes loss / frequency drop for such long distance will be very significant in either direction, to kick start the 3 phase motor.

[nfssaad]

that is a very heavy motor. not feasible for using long distance from source
