Enphase Upgrade Program for Early Adopters

In the nearly ten years since we introduced our very first microinverters, we have made unprecedented advancements in microinverter design and manufacturing. Many millions of test-cycle hours, and analysis of thousands of terabytes of product data, have allowed us to massively improve product performance and reliability. As part of our commitment to quality and service, we are making these product advancements available to our very first customers. 

How It Works for System Owners

The upgrade program will be available to all system owners of legacy, second-generation microinverter systems. 

Below, you will find details about the three options Enphase is offering to these system owners. These options are not arbitrary. We spent many hours making phone calls to our customers and asking what kind of programs would be most interesting to them.

Participation in this program is completely voluntary; should a system owner choose not to participate, their legacy microinverters will be fully covered through the remainder of the 15-year product warranty. 

How It Works for Installers

All Enphase installers can choose whether they'd like to participate in the upgrade program. System owners will be able to work with their existing installer on the upgrade. If they don't have an existing installer they'd like to work with, we will be connecting them with an Enphase installer in their area.

If you'd like to participate in this program as an Enphase installer for your customers (and, optionally, for new customers), please sign up below to secure a spot in the program.

Below are the options that will be available to legacy system owners.

Option 1 Microinverter Upgrade - icon

Option 1: Microinverter Upgrade

System owners can upgrade their second-generation microinverters to our latest seventh-generation microinverter, the Enphase IQ 7-PD. We are offering the equipment at cost, and including all required equipment at a flat rate of $67.50/panel, including:

  • Enphase IQ7-PD: Our IQ 7-PD Microinverters, powered down to be compatible with the existing solar panels and system equipment
  • Q Cable
  • Accessories Kit: Disconnect Tool, Branch Terminators, Q Seals and Q Clips
  • Q Adapters (not required for all systems)
  • IQ Envoy, Production CTs and Consumption CTs

With the Microinverter Upgrade option, system owners will have access to our latest and most reliable technology. In fact, our new IQ 7-PD Microinverter is an order of magnitude more reliable than our second-generation products. Plus, it comes with a 25-year product warranty and two-year service agreement.

This new technology also allows system owners to view and track their household's energy usage with Consumption Monitoring, letting them see how much energy comes from their panels and how much comes from the utility. You can learn more about this feature here. Plus, these new system will be storage-ready should system owners choose to add Enphase AC Batteries now or down the road. Please note that this feature requires installation of hardware near the home's main electrical service panel, and availability depends on the configuration of the home's service panel.


How does it work? Sign up below and we will send you information on how to participate in the upgrade program.

Cost: We're offering Enphase equipment to legacy system owners at a flat rate of $67.50/panel. Labor costs will be quoted separately by you, the installer. While system size and specifications vary, we have let system owners know that the average cost to upgrade a 20-panel system typically falls between $2,300-$3,100 for equipment and installation.

Option 2 Full System Upgrade - icon

Option 2: Full System Upgrade

The Full System Upgrade option allows system owners to upgrade their entire solar system with a brand new one. The new system will be built around the latest, higher energy producing Enphase Energized AC Module, which has our seventh-generation microinverters built right into the solar panel. 

With the Full System Upgrade, you will remove your customer's existing system (including microinverters and panels) and replace it with the new Enphase powered AC Modules so that they have the highest performing and most reliable Enphase products on their roof. In fact, our seventh-generation microinverters perform at 97% efficiency. Higher reliability means fewer service calls and repairs. Plus, if the new system meets the requirements, you may also qualify for the Federal Investment Tax Credit (ITC). 

This new technology allows homeowners to be Ensemble ready. Please assist the homeowners to determine which of the two Enphase AC Modules would best suit their needs.

LONGi modules, with their aesthetic all-black frame and backsheet combined with Enphase IQ7 Microinverter offer an optimized AC Module for your home. The Longi Mono PERC PV module cell has a passivated rear side and a laser grooving process, which significantly improves cell efficiency. The warranty for this product is 25 years for the Enphase Microinverter, and 10 years on the PV module along with a 25-year linear performance warranty, and a two-year service agreement. You can read more about the Longi AC Module here

Solaria PowerXT-AC Module, which is a visually stunning, all-black, high-output solar panel integrated with our Enphase IQ 7+ Microinverter. With this AC Module Upgrade comes a 25-year product warranty and two-year service agreement. You can read more about the Solaria PowerXT-AC Module here.


How does it work? Sign up below and we will send you information on how to participate in the upgrade program.

Cost: The LONGi AC Module costs $349/panel USD and the Solar PowerXT-AC Module costs $469/panel USD, which includes the microinverter, panel, Envoy, and all accessories. Labor costs are quoted separately by you, the installer. We have let system owners know that installation costs for the Full System Upgrade are typically higher than the Microinverter Upgrade (Option 1), as new racking equipment and permitting may be required.

Option 2 Next-Generation Upgrade - icon

Option 3: Next-Generation Upgrade

The next generation upgrade offers Enphase Energized AC Modules, in which a smart-grid ready Enphase IQ 7™ series Microinverter is pre-installed on a high-powered solar panel, together with Ensemble Storage with IQ8™ grid agnostic technology.

This technology provides backup function and allows your solar system to operate even in the absence of the grid.

We have also compiled some frequently asked questions below:

What legacy microinverters qualify for the Enphase Upgrade Program?

The Enphase M190, M210, D380 and M175 microinverters are considered legacy microinverters that qualify for the Enphase Upgrade Program.

What are the terms of the warranty and service agreement?

New Enphase products are covered by our industry-leading 25-year warranty, as well as a two-year service agreement, which covers any installation costs incurred for replacement of warrantied microinverters, should any microinverters fail within the first two years from your purchase date.

Do I need to upgrade my entire system at once or can I upgrade one microinverter at a time?

The Enphase Upgrade Program is being offered for a limited time for legacy system owners, and availability of the program and product is limited. In order to be eligible for the discounted cost, all of the system’s legacy microinverters must be upgraded at one time.

Will Enphase stop servicing legacy microinverters in case of failure?

No, Enphase will continue to honor the 15-year product warranty on all of its legacy microinverters. For more information about the Enphase warranty, go here.

What happens to old equipment?

Should you choose to participate in the upgrade program, we ask that you handle the removal of all old equipment, working with local facilities to ensure that components are recycled appropriately.

If I participate in the upgrade, will I need to get new permits for legacy systems?

For Option 1 - Microinverter Upgrade, the IQ 7 microinverter will be adjusted to meet original permit requirements so that new permits should not be required. For the other program options, new permits will need to be secured, as with any new solar system installation.

What if system owners don’t want to participate in the program?

Should system owners choose not to participate in the program, nothing about their system or its warranty changes. Everything will stay the same throughout the remainder of the products' original 15-year warranty.


To be eligible to participate as an installer in the Enphase Upgrade Program, we ask that you respond to homeowner inquiries within 2 business days, whenever possible. If no response is received after 2 business days, we may provide additional options to the homeowner to help them move forward with the upgrade. Please see additional installer terms here.
