Overview; Descriptions And Features - Franklin Electric SubDrive Solar Manuel D'installation

Overview

The SubDrive Solar controller is a variable speed motor drive designed to run a Franklin Electric
three-phase submersible induction motor. The SubDrive Solar provides water to remote locations by
converting high voltage, direct current from a solar array into alternating current to run a standard AC
submersible motor. When solar power is not available, the controller can automatically switch to an
alternate single-phase AC input such as a generator or inverter from battery, if available. The controller
provides fault detection, motor soft start, and speed control. The SubDrive Solar is designed to provide
these features with the plug-and-play ease of installation similar to a single-phase control box.
The SubDrive Solar is designed with the high standard of reliability expected of Franklin Electric
products. The controller attempts to drive the pump and motor to deliver water even under adverse
conditions, reducing output as necessary to protect the system components from damage, and only
shutting down in extreme cases. Full operation is restored automatically whenever abnormal
conditions subside.
Inspection
Before you begin, receive and inspect the SubDrive Solar unit. Verify that the part number is correct
and that no damage has occurred during transit.

Descriptions and Features

The SubDrive Solar system controller is based on a standard SubDrive platform controlling a Franklin
Electric 4-inch three-phase motor driving a 4-inch submersible centrifugal pump powered by a DC solar
array or an optional AC generator back-up.
The SubDrive Solar controller continuously monitors system performance and incorporates a number
of features for pump system protection. In the event of a fault, the SubDrive Solar will indicate the
type of fault through the three seven-segment displays.
The SubDrive Solar system is optimized for pumping under adverse input power conditions
unique to solar arrays.
• Internal diagnostics will tolerate a lower input voltage.
• Whenever possible, the controller attempts to regulate the pump load in a manner that optimizes
for maximum power transfer from the solar array.
• The drive automatically switches to AC back-up power (when available) if the DC primary source is
unable to support pump operation.
The controller construction is ruggedized for hostile environmental conditions.
• The case is constructed of heavy-gauge zinc-plated steel to resist rain, animal intrusion, and
prolonged direct exposure to sunlight.
• The seals are designed for NEMA 3 (IEC rating IP55), (dust-tight, withstands directed jets of water).
• For maximum protection against dust, there is no external cooling fan or other external
moving parts.
An easy-to-use interface is provided to enhance configurability and enable remote
system monitoring.
• A three-digit seven-segment display provides a detailed indication of system status.
• A small keypad offers flexibility for selection of user options.
• A continuous data connection for remote telemetry is made available via an RS-485 port.
• If using remote telemetry, follow the register information found in the RS-485 addendum.
