Warranty for full terms and services (enphase.com/warranty).
✓
NOTE: When replacing an Enphase IQ System Controller, you must replace it with an IQ System Controller of
the same type, with the same AC current rating.
✓
NOTE: Properly mount the IQ System Controller. Ensure that the mounting location is structurally suited to
bearing theweight of the IQ System Controller.
✓
NOTE: During use, storage, and transport, keep the IQ System Controller:
•Properly ventilated
•Away from water, other liquids, heat, sparks, and direct sunlight
•Away from excessive dust, corrosive and explosive gases, and oil smoke
•Away from direct exposure to gas exhaust, such as from motor vehicles
•Away from falling or moving objects, including motor vehicles. If mounted in the path of a motor vehicle, we
recommend a 91cm (36-inch) minimum mounting height.
•In a location compliant with fire safety regulations
•In a location compliant with local building codes and standards
✓
NOTE: While IQ System Controller provides capability for connection of a generator, it does not presently
support use withgenerators. Do not attempt to connect a generator until IQ System Controller is ready to
support a generator. This functionality is reserved for future use and will require an upgrade process to be
followed by a qualified electrician.
✓
NOTE: IQ System Controller is not suitable for use as service equipment in Canada.
Unboxing the new IQ System Controller unit
WARNING: Risk of injury. Take care when lifting. The IQ System Controller is heavy 38.5
kg (85 lbs). WARNING: Risk of injury and equipment damage. Avoid dropping the IQ
System Controller. Doing so may create a hazard, cause serious injury, and/or damage
the equipment.
When unboxing the new IQ System Controller unit, follow the instructions in the QIG to carefully
unbox the unit from the carton box without damaging it since the same box should be reused for
shipping back theold RMA’d IQ System Controller unit to Enphase.
Delete existing IQ System Controller using Enphase Installer App
When replacing an IQ System Controller on site (RMA) the old IQ System Controller must be deleted
using Enphase Installer App. There would be a Serial Number of IQ System Controller based on
which the RMA request is raised. Use theSerial No. to identify the IQ System Controller at site.
1. Don’t power down system until instructed later in the process.
2. Confirm that all the devices are powered ON.
3. Install Installer Enphase App using the below links:
oiOS
oAndroid
4. Log in to the application using Enphase Installer credentials.
5. Search for the system in the Enphase App.
6. Tap on the system and make sure the IQ System Controller to be deleted is part of the system.
7. Connect to the IQ Gateway using AP mode and Go to Step 4 (IQ Gateway Connectivity) to
confirm thedevice is connected to the IQ Gateway. Also make sure IQ Gateway is
connected to Enphase App either through Wi-Fi, Ethernet or Cellular.
8. Go to Devices and Array (Step 2) and select and delete IQ System Controller as
shown in images below. The device will be removed from Enphase App and will be
synced to ITK after IQ Gatewayreports the deletion.

Power Down Sequence
1. Turn off DC switches on all IQ Batteries.
2. Open IQ Battery breaker in IQ System Controller.
3. Open PV breaker in IQ System Controller.
4. Open the mains breaker.
5. Disconnect the grid source power supply (breaker in main panel).
6. Open Generator (reserved for future use) breaker.
7. Measure AC voltage on all the following terminals - PV/IQ Battery/Grid/Generator. It is safe
towork on IQ System Controller only when no voltage is detected on any of these terminals,
and you have ensured that all IQ Battery units have DC powered off.
Replace IQ System Controller unit
DANGER! Risk of electric shock. Check that all circuits connecting to the IQ System
Controller are de-energized before wiring. Follow below instructions in the sequence
mentioned.
1. To install the new IQ System Controller, the old IQ System Controller that was deleted
using ITK must be replaced.Follow the below steps to replace the IQ System Controller
unit.
a) Disconnect all wires in a safe manner (the “AC power wires” shown in the figure
below need to be disconnected).
b) Use handles (recommended) to remove old IQ System Controller from the wall.
c) Remove the PV, IQ Battery, and Gen breakers, as well as CTs if installed in IQ
System Controller,to keep them for the new IQ System Controller.
2. Follow the steps in IQ System Controller Quick Install Guide to install the new IQ System Controller.

2. Ensure that all electrical circuits external to IQ System Controller are completed and
safe beforeenergizing IQ System Controller.
3. To commission the system, follow the instructions in the Enphase Installer Applicationand
the Commissioning Guide for energizing IQ System Controller. Key steps are also outlined in
section
1.5 below.
4. Energize the circuit feeding the IQ System Controller. If installed, turn the breaker feeding the
IQ System Controller tothe ON position.
5. Close and secure the door of the IQ System Controller.
Provision new IQ System Controller using Enphase App
1. Add and provision the new IQ System Controller as written in below steps.
Enphase App, Devices & Array
1. Go to ‘Devices and Array’ (step 2). Select ‘Add Device’ and enter the total count of IQ
System Controllerto be added in the system and Select ‘Done’.
2. Tap on ‘IQ System Controller’ and then manually scan the serial numbers of IQ
System Controller into Enphase App.
Provisioning the IQ System Controller
1. Ensure that the Enphase Energy System communications kit or COMMS-KIT-01 is plugged
into IQ Gateway USBports.
2. Ensure that the Enphase Mobile Connect Cell Modem is plugged into the IQ Gateway USB port.
3. Make sure you are still connected to IQ Gateway in AP mode. Go to ‘Provisioning Devices -
Step 5’and tap on ‘Provision Devices’.

4. Device provisioning will not be successful if both the COMMS-KIT-01 and cell modem are
missing or not plugged in.
5. Enphase App will begin provisioning the replaced IQ System Controller:
a. It will show the status of grid profile whether it is updated or not.
b. Only replaced IQ System Controller will be provisioned.
•During provisioning, the status flows as follows:
•Discovered / not discovered (Enphase App is able to discover the device using
Bluetooth Low Energy (BLE).
•Waiting for provisioning (The initial communication is being established.
Enphase App is sending network information to IQ System Controller using
BLE).
•Waiting for acknowledgement (IQ Gateway is trying to communicate to the IQ
System Controller usingthe wireless 2.4 GHz radio).
•Provisioned (IQ Gateway can communicate with the IQ System Controller).
•Once provisioning is complete, click Done.
Confirm new IQ System Controller is operating properly
1. Confirm that the IQ System Controller is communicating with the IQ Gateway by checking
Enphase App Step2: Devices & Array. IQ System Controller should display
“communicating” as follows:
The above step ensures that IQ System Controller is added successfully and is communicating.
