Enphase microinverter. The Enphase microinverter is not protected from damage due to moisture trapped in cabling systems. Never mate microinverters to cables that have been left disconnected and exposed to wet conditions. This voids the Enphase warranty.
Enphase IQ Microinverters over onsite AC power lines and transmits the data to the Enphase App through an internet connection. The IQ Gateway Metered can monitor up to 300 Enphase IQ Microinverters. For details, refer to the...
-20°C−65°C (-4°F−150°F). Ease of design PV systems using Enphase microinverters are very simple to design and install. You will not need string calculations or cumbersome traditional inverters. You can install individual PV modules in any combination of PV module quantity, type, age, and orientation. Each microinverter quickly mounts on the PV racking directly beneath each PV module.
IQ7+ and IQ7A Installation and Operation Manual - India Compatibility The Enphase IQ Series Microinverters are electrically compatible with PV modules, as listed in the following table. For specifications, see the Technical specifications in this manual. You can refer to...
Select the correct conductor size based on the distance from the junction with the microinverter AC branch circuit to the circuit breaker in the electrical panel. Enphase recommends a voltage rise total of less than 2% for the sections from the microinverter AC branch circuit to the circuit breaker in the electrical panel.
IQ Cable. • Enphase Installer App. Download the Enphase Installer App and open it to log in to your Enphase Account. With this mobile app, you can scan microinverter serial numbers and connect to the IQ Metered to track Gateway system installation progress.
Step 3: Mount the microinverters A. If the Enphase DC bulkhead connectors are not already attached to the microinverters, attach them now. Make sure they are fully seated. B. Mount the microinverter bracket side up (as shown) and under the PV module, away from rain and sun.
• 6 mm mounting hardware: 5 N m • 8 mm mounting hardware: 9 N m Step 4: Create an installation map The Enphase installation map is a diagram of the physical location of each microinverter in your PV installation. Copy or use the blank installation map in this manual to record microinverter placement for the system, or provide your own layout if you require a larger or more intricate installation map.
Enphase App, during system registration, or through the Enphase Installer App at any time. You must have an Enphase IQ Gateway to set or change the grid profile. For more information on setting or changing the grid profile, refer to the Enphase IQ Gateway Metered Installation and Operation Manual at enphase.com/support.
If a microinverter registers a DC Resistance Low - Power Off condition, you can attempt to clear this condition. If the condition does not clear after you perform the following procedure, contact Enphase Energy Support at https:/ /enphase.com/contact/support.
Specifications section in this manual. L. Swap DC leads with a known good, adjacent PV module. If, after checking the Enphase App periodically (this may take up to 30 minutes), the problem moves to the adjacent module, this indicates that the PV module isn’t functioning correctly. If it stays in place, the problem is with the original microinverter.
H. Energize the AC branch circuit breaker and verify the operation of the replacement microinverter by checking the Status LED on the connector side of the microinverter. Use the Enphase Installer App to delete the old microinverter serial number from the Enphase IQ Metered database.
Communications LED flashes green during the scan. L. Log in to the Enphase Installer App to use the Enphase Installer App’s array builder to add the newly detected microinverter to the virtual array. M. Ship the old microinverter to Enphase using the supplied return-shipping label.
PV module widths. The microinverters plug directly into the cable connectors. The IQ Cable is compatible with many PV racking systems. For a list of approved PV racking systems, see the PV racking compatibility document on the Enphase website at enphase.com/support. Connector spacing options IQ Cable is available in three connector spacing options.
If needed, Enphase IQ7 Series Microinverters can absorb or inject reactive power, provided that current and voltage ratings are not exceeded. The following figure shows the active power (P) capabilities curve relative to reactive power (Q) related to the power rating in the operating voltage range for the Enphase IQ7 Series. •...
