Frequently asked questions
How can installers tell if the firmware has been updated?

In the Enphase Installer Portal, formerly known as Enlighten Manager:

1. Click Systems tab

2. Select a system from the list

3. Click the Devices tab

4. The Processor Load column shows the existing firmware version

How much energy should my array produce?

Many factors determine a system’s energy production on a rooftop, compared to its energy production in standard testing conditions. Your solar professional may have provided a production estimate using estimation tools like PVWatts. Estimation tools consider many factors such as location, seasonal variation, roof pitch, wiring, and electrical losses to calculate production estimates.

You can use the following formula for a simple estimate:
DC system size (kW) × hours of sun/day × system efficiency = estimated AC daily energy production

5 kW × 5 hr/day × 0.77 = 19.25 kWh/day

Can I pair IQ8 Series Microinverters with bifacial solar modules?

You can pair Enphase IQ8 Series Microinverters with bifacial solar modules if they are electrically compatible and installed according to the Quick Installation Guide supplied with the microinverters.

In case there is no mandatory regulation for inverter sizing by the local utilities, use the microinverter sizing methodology of a conventional monofacial module; however, you can use the real power, or the gained power, rather than the nominal power of the bifacial solar module. For example, if a 20% gain is expected, then refer to the module output parameters associated with the 20% gain instead of the nameplate rating of the module. 

You can always use the Enphase Module Compatibility calculator to feed-in the module output parameters and check the compatibility.

While ordering microinverters with integrated MC4 connectors, do I get the Q-DCC-2 adapter cable, too?

Microinverters with integrated MC4 connectors will not be shipped with a Q-DCC-2 adapter cable, as they are no longer necessary.

Where can I get data sheets for microinverters with integrated MC4 connectors?

Download the data sheets or browse all our technical publications in the Documentation Centre.

Is there a new cabling system designed for IQ8 Series Microinverters?

Enphase IQ8 Series Microinverters are compatible with the existing IQ cabling system, which is currently being used with existing IQ6 and IQ7 Series Microinverters and provides a similar installer experience.

Will system owners use the same Enphase App to monitor their commercial Enphase Energy System and their home energy system?

Yes, all system owners will utilize the same app, irrespective of system type. Owners with multiple systems can access all their Enphase systems from a single login to the Enphase App.

Will microinverters requiring MC4 adapter cables be phased out completely?

Yes, all microinverters will eventually have integrated MC4 connectors. Enphase is gradually transitioning each inverter in a phased manner.

Will installers use the same commissioning and monitoring software for Enphase Commercial Energy Systems as I do for other Enphase installations?

Yes, you will use the same commissioning and monitoring application for commercial systems, and you will be able to monitor your entire fleet of installed systems—irrespective of individual site type or microinverter.

Can the installer reduce the cable slack to connect to the solar panel lead cable?

It doesn't use an external bulkhead adapter, so the overall cable is a bit less. However, module leads are typically 4 to 6 feet long, or 1.2 to 1.6 meter long, so the impact is minimal.

What are the grid interconnection voltages supported by IQ8 Series Microinverters?

All IQ8 Series Microinverters have an operating range of 184 V to 276 V L-N AC voltage.

Are there any special installation instructions for microinverters with integrated MC4 connectors?

There are no special instructions for microinverters with integrated MC4 connectors. Follow the same installation practices as outlined in the Enphase installation manual.

Can my system produce power on a cloudy day?

On cloudy or rainy days, your system produces less energy compared to days with a clear sky. The impact of clouds on your system’s energy production varies depending on the cloud cover and the duration it obscures sunlight over your panels during the day.

Maximum energy is produced when the sky is bright and clear—especially if the angle of the panels towards the sun is optimal and the temperature is cool, since solar panels work more efficiently in lower temperatures. If the weather is clear but production is still low, check for dirt, snow, shade, or debris on the surface of the solar panels.

How do I learn more about the Enphase microinverter families?

Refer to and learn more about Enphase microinverters.

Why is my solar panel rating higher than my microinverter rating?

PV modules seldom produce power at their test condition power rating. This leads installers to pair PV modules with power ratings higher than the inverter power rating. In many locations, high DC:AC ratios may not result in significant clipping losses. To learn more, refer to the technical brief, which can be accessed at

Is there a webinar where homeowners can learn more about Enphase Energy System?
How does the Enphase Energy System work?

The Enphase Energy System brings solar, microinverter, and software together in one complete package so that you can make, use, save, and sell your own power. To learn more, see the video
