Ocean Poolpump Inver iQ 300

Use cases

• Monitor actual flow rate and water pressure on a live dashboard to verify filtration performance.
• Create an alert when an alarm counter increments so you can respond to pump faults before the customer notices.
• Adjust the volume flow setpoint remotely to increase flow during backwash cycles without visiting the site.
• Track cumulative energy consumption over time to demonstrate savings compared to a fixed-speed pump.
• Verify digital input 1 status remotely to confirm the pump is receiving a valid start signal from the safety circuit.
• Log motor power data to identify unusual load patterns that may indicate a clogged filter or blocked impeller.

Installation

1. 1Wire the Modbus RTU bus (A, B, GND) from the ModbusCloud gateway (MCG or MLP series) to the RS-485 terminals on the Inver iQ 300 control unit, observing correct polarity.
2. 2If the control unit is mounted remotely from the pump motor, use a minimum cable cross-section of 4 x 2.5 mm2 and keep the distance under 30 metres.
3. 3On the pump display, set menu 15.2 MODBUS ADDRESS to 2, menu 15.4 MODBUS PARITY to 2, and configure time program 1 to EXTERNAL with a 00:00 to 23:59 time range.
4. 4Ensure digital input IN1 is wired to your safety or automation relay so the pump can be started and stopped independently of Modbus.
5. 5In the ModbusCloud portal, import the Peraqua Ocean Inver iQ 300 template, set the gateway serial port to 9600 baud, 1 stop bit, no parity, and assign slave address 2.
6. 6Confirm live readings for flow rate, pressure, and motor power appear on the dashboard before putting the system into service.
