Welcome to Enphase.

Solar panels may get all the glory, but it's the inverter that does all the work in a solar energy system. Tucked beneath each solar panel, microinverters convert the direct current (DC) power collected from the solar panels to alternating current (AC), the form of electricity your home can use.

Choosing the right inverter technology for your system is one of the most critical decisions to make when going solar. Enphase microinverters offer the most advanced inverter technology on the market, which means higher production, greater reliability, and unmatched intelligence.

Store the energy you produce with Enphase IQ Batteries. These batteries solve the basic dilemma of solar energy — while your system produces the most energy midday, most households use the most energy in the morning and evening. With home solar batteries, you can save the energy you produce during the day and use it when you need it most.

The Enphase App gives you a real-time, in-depth view of your system's production and energy consumption. You can use the Enphase App to track your system's performance, monitor your system's health, and share data with family and friends. You can download the app from the Apple Store or Google Play.

Want to learn more about the Enphase App? Head over to the monitoring page, or take a look at some common questions in the homeowner support center.

Consumption monitoring is an optional feature that measures the energy usage in your home. You may hear consumption monitoring referred to as energy usage monitoring or consumption metering. These terms are largely interchangeable, with a couple of nuances. You monitor or view your consumption in the Enphase App. Consumption metering refers to the hardware installed to enable the monitoring. Click here to learn more about consumption monitoring.

If you are interested in production or consumption monitoring, please contact your installer about these optional features. Your installer will assess your site and make a determination about whether your electrical service panel will support the installation of the required hardware.

Production and consumption meters are required when you have an Enphase IQ Battery.

In addition to the above Enphase components, your system will also include photovoltaic (PV) solar panels (also called "modules"). Solar panels are made up of many solar cells, which turn the sun's energy into direct current (DC) electricity. This energy is passed to the microinverter, which converts it to alternating current (AC) power.

There are a wide range of solar panels that come in a variety of colors, sizes, and materials. While Enphase doesn't manufacture solar panels, we work with module partners to produce the AC Module, which combines our microinverter with a solar module into one integrated unit. Your solar installer can help you pick out the right solar panel for your system.

The IQ Gateway is the communications and control center behind your energy system. This small device is the networking and command hub of your system, and it's responsible for monitoring your system's performance by collecting real-time data from your solar and storage system. If your system includes storage, the IQ Gateway also manages charge and discharge of the batteries.

Your system will also include a mounting system (also called solar module racking), which is the equipment that attaches your panels and microinverters to your roof or the ground. These materials and components may vary depending on your local weather patterns, roof material, etc.

These additional components may include:

• Mounting rails, which are attached directly to the roof
• Module clamps, which secure the solar panel to the mounting rail
• Pole mounts, foundation mounts or ballasted footing mounts for ground-mounted systems

Your solar installer will typically recommend a mounting system and select the additional components that are required.

Once you've made the choice to go solar, you'll need to find a solar installer to guide you through the process. Your solar installer will be an essential resource along the way, from designing your system to installation and ongoing maintenance. Choosing an installer you trust, with the right qualifications and experience for your needs, will make your solar experience a lot smoother.

That's why we've created the Enphase Installer Network, an online database that helps you select an Enphase installer in your area. The Installer Network will show you a list of Enphase installers who cover your area, as well as how long they've been installing Enphase, how many Enphase installations they've completed in the past year, and other certifications that may help you make your decision.

Find an installer using the Enphase Installer Network or learn more about how the Enphase Installer Network works.

When you reach out to a solar installer, they will want to visit your home to assess your roof and gather the details they need to prepare a quote or proposal for you. You may want to have a few installers come out to your home so you can get a better feel of which installer you're most comfortable with. When the installer arrives at your home, they will examine your electrical service panel, assess your roof, and may even suggest some tree trimming near your house.

They will also ask you about your home's internet access, as connecting your Enphase system to the internet allows you to monitor its performance and allows us to send out any necessary firmware updates. Can't get internet? Not to worry, cellular monitoring is also available.

Once you've selected an installer and have started the paperwork for your system, your installer will work with you to schedule the installation. Installation typically takes 1-3 days, depending on the size of your system. 

On the day of the install, your installer will usually set up a staging area with close access to the roof, where they will lay out all of their tools and equipment. While much of the installation happens on the roof with the panels, microinverters, and other components, some of the installation will also happen near your electrical panel, where the installer will set up the IQ Gateway. You may need to be available at the beginning of the install to provide your installer with the information needed to connect the IQ Gateway to the internet.

When system installation is complete, your installer will briefly turn on your new system to verify that everything is working as designed. If additional configuration steps are required by your utility, your installer will take care of these during this brief test window. Following configuration and verification, the system will be powered off while you await Permission to Operate (PTO) from your utility.

While you await PTO, do not power off or move any of the equipment your installer has placed. Be sure to keep the IQ Gateway plugged in and connected to the internet. The IQ Gateway is located for optimum communication with the microinverters and for remote turn-on when PTO is received. If you move the device, monitoring may be compromised. If you disconnect it from the internet, your installer may not be able to turn on your system remotely, and you may have to wait until they are in your neighborhood again to power on your system.

Do not power on your system until PTO is received. It is illegal to run your system before you have permission to operate, and it may be costly to do so. Solar installations require bi-directional utility meters: meters that spin backward when your system is feeding the grid and forward when you are buying energy from the grid. Until a bi-directional meter is installed, you’ll be charged for all the electricity you generate.

When PTO (Permission to Operate) is received, your installer will power on your system. Most systems can be powered on remotely, but occasionally, installers may come out to your house again to power on your system.

Within two days of power on, you will be sent your MyEnlighten login credentials. Your user name is the email address you provided to your installer for registration. You will be sent a temporary password that you will reset when you first log in.

If you have not received your welcome email within three days of power up, please check your spam folder, then contact your installer.

Your installer will register your system with Enphase using the email address you provided to them during the sales process. There are no additional steps you need to take to activate Enlighten monitoring for your system, and the software is free for system owners. (If you have recently purchased a home with Enphase equipment already installed, please jump to Change of Ownership below.)

After your installer receives notice that you have permission to operate your solar system (PTO), your installer will power on your system. Most systems can be powered on remotely, but occasionally, installers may come out to your house again to power on your system.

After your system is powered on and has operated successfully for 24 hours, you will be sent your Enlighten login credentials. Your username is the email address you provided to your installer. You will be sent a temporary password that you will reset when you first log on.

Look for your welcome email in your spam or junk folder if you do not receive it within three days of system turn-on following PTO.

If you have deleted your welcome email, you can request a new password by visiting enlighten.enphaseenergy.com and clicking "Forgot your password?"
