What are the specifications of the IQ8 microinverters?

Specification sheets can be downloaded for each Enphase micro inverter from the online store

What are the benefits of IQ8 microinverters over IQ7 Series?

The IQ8 Microinverters will generate more energy per square metre. IQ8 Microinverters support the latest high-current solar modules using M10 wafers with a higher DC current handling capacity of 14 A. In comparison, IQ7A Microinverters support up to 10.2 A. 

The IQ8HC Microinverter has a power output of 380 VA which assists in paring with high wattage and current PV modules up to 505 W for STC rebates.  

Is the current Envoy-S Metered compatible with IQ8 microinverters?

Yes, you just need to ensure the Envoy has the latest software.

Is the IQ8 compatible with previous generation Enphase inverters?

IQ8 Series Microinverters cannot be mixed together with previous generations of Enphase microinverters (IQ7 Series, IQ6 Series, etc) on the same IQ Gateway.

IQ Micros require an Envoy-S Metered to work. M-Series micros work with both Envoy-R and Envoy-S Metered.

What is the IQ Relay?

The IQ Relay must be installed with any IQ8 system. It ensures compliance to Australian Standards requirements. The IQ Relay de-energises micro inverter during grid abnormalities and it improves overall system quality.

Is the IQ relay required for all installations?

Every branch of IQ8 microinverters is required to be fed through a IQ relay, unless another anti-islanding device is used like the IQ System controller.

Why have a IQ relay?

The IQ relay provides a mechanical point of isolation for grid protection and anti-islanding as required by clause 7.2 of Australian Standard AS NZS 4777.2 – 2015 Grid connection of energy systems via inverters – inverter requirements.

Where do I install the IQ relay?

The IQ relay is ideally installed adjacent to the Main Switch (Inverter Supply) at the main switchboard. However, because of the space restrictions that often exist in the main switchboard, AC Solar Warehouse provides pre-wired Enphase Solar Distribution Boards which contain the IQ Relay, the Envoy, and all other components required to complete an Enphase IQ8 installation.

Is IQ8 compatible with the Enphase IQ Battery 5P?

Yes.

How many IQ8 micro inverters can you install in one branch?

Maximum number of IQ8AC microinverters per single phase 20A (L+N) branch circuit is 11

Maximum number of IQ8AC microinverters per three phase 20A (3L+N) branch circuit is 39

Maximum number of IQ8HC microinverters per single phase 20A (L+N) branch circuit is 10

Maximum number of IQ8HC microinverters per three phase 20A (3L+N) branch circuit is 36

Recommended maximum units per single/multi-phase IQ Cable section to reduce voltage rise in IQ Cable

IQ8AC microinverters single phase (L+N) – 8

IQ8AC microinverters three phase (3L+N) – 18

IQ8HC microinverters single phase (L+N) – 8

IQ8HC microinverters three phase (3L+N) – 18

It is recommended to centre feed IQ Cable within microinverter branch circuits to minimize the voltage rise. These design limits should ensure voltage rise and line conductor resistance on the IQ Cable are maintained within acceptable limits. In locations with risk of high grid voltage at the point of connection, it may be necessary to decrease the maximum number of microinverters on the IQ Cable section by as much as 50%.

Can the IQ Microinverter System be used for commercial applications?

Yes, the IQ Microinverter System can be used for commercial applications.

What is the Q Cable?

The IQ System uses the Q-Cable, a light-weight, 2-wire cable that no longer requires an earth conductor on the roof.  This is because the IQ series microinverters are double insulated and hence do not require earthing.

Will IQ8 work for 3-phase systems?

Yes

What is the warranty for Enphase IQ8 microinverters?

IQ8 Microinverters will be backed by an industry-leading 15-year limited warranty as standard, extendable to 20 or 25 years.

Will IQ8 Microinverters have grid-agnostic capabilities?

IQ8 Microinverters will deliver grid-agnostic capability when used as part of the Enphase Energy System with an IQ System Controller 3 INT and IQ Battery 5P to provide backup power.

Will IQ8 Microinverters work with the existing IQ Gateway, IQ Relay, and IQ Cable system accessories?

Yes. Existing IQ Gateway (Metered), IQ Relay (single-phase and multi-phase), and all existing IQ Cable variants will work with IQ8 Microinverters.  

Are IQ8 Microinverters compatible with the Enphase IQ Battery 5P?

Yes, IQ8 Microinverters will be compatible with the IQ Battery 5P and IQ System Controller 3 INT. 

Is there a change in the installation and commissioning process for IQ8 Microinverters compared to IQ7 Microinverters?

The installation and commissioning process remains the same. IQ8 Microinverters must be commissioned using the Enphase Installer App version 3.27.1 or above. IQ8 Microinverters require gateway software version 7.6.168 or higher, if your Gateway has a lower software revision it will be upgraded using the Installer App during commissioning. Please note that we don’t support mixing IQ7 Series and IQ8 Series Microinverters in the same system.

Want to know more about the Enphase IQ system

When Enphase set out to develop the IQ System, they wanted to not only streamline the product for better performance within the smallest package but also streamline the installation process for a quicker and more effective installation. The IQ System saves time before you even reach the job site, simplifying stock management, packing more lightweight microinverters per box to reduce trips up the ladder, and bundling cables so they can be easily taken to the roof.  It helps that the two-wire Q Cable uses less conductors and weighs 50 percent less than its predecessor, the trunk cable. The IQ System was introduced to the US market in early 2017 where installers and systems owners have been benefitting from the new design.

IQ reduces electrical component parts count

One of the challenges of conventional solar installations is efficiently managing stock of components required for the installation. The AC Solar Warehouse Enphase Solar Distribution Board with the IQ Envoy communications gateway combines multiple electrical enclosures into one, eliminating the need for a separate subboard,  Envoy enclosure, and AC disconnect, as well as all the hardware to connect these pieces together.

IQ improves design flexibility

One of the inherent limitations of string inverter systems is the need to always complete a loop in the electrical design. With DC solar systems, there’s no opportunity to branch off to islanded arrays on complex rooftops or in response to on-the-fly design changes. The onsite-wireable connectors in the IQ System allow for safe and simple connections from any open connector and the ability to center feed any section of cable up to a 20-amp limit allowing the system to be built as a tree with branches rather than a constricted linear design.  The lighter two-wire Q Cable also makes it easier to handle wire management, whether that means fastening cable to rails or to the solar module frame using standard clips in a rail-less mounting system.

IQ enables faster commissioning

A new generation of power line carrier communications made it possible to remove the neutral conductor from the Enphase cabling system and results in new Envoys for the IQ System. This, along with new embedded software, results in a notable improvement in microinverter detection during commissioning.  Because the neutral line shares a circuit with other electrical devices in the house, devices that carry a lot of noise on the line, detection could take as long as 15-20 minutes.  During testing, the IQ Envoy detected a full set of 20 microinverters in less than 5 minutes.  Detection might not always be so fast, but we expect the new communications to cut the time in half. All the process improvements in the IQ System build upon an industry-leading home energy solution that comes with built-in advanced grid functionality often required by utilities.  As grid conditions change, Enphase’s ability to report on each microinverter’s performance and remotely push firmware updates to the field will prevent the need for costly, time-consuming, and unnecessary site visits.

What’s in the name

Enphase named their latest microinverter technology the IQ because it’s very intelligent, for homeowners and especially for installers.  They placed the letter Q in front of their new cabling accessories because Q stands for “quick”.

Performance, Reliability and Safety

The IQ design is now a global SKU (Stock Keeping Unit), which means manufacturing only one type of inverter globally.  This provides a focus on one inverter design and increased mass production delivering even greater reliability and performance. Enphase has demonstrated this in Australia with unmatched reliability never seen in solar inverters.  You install it, it works.  It’s as simple as that! Using IQ microinverters means there are no dangerous DC voltages which completely eliminates the risk of solar fires.  To find out more about solar fires please click here
