Enphase Energy Reviews 

Will not guarantee their monitoring system will work AND NO RETURN POLICY Shitty customer suppor
I have had a 10 year old residential solar system. The system has 38 panels each with Enphase M250 inverters. The last year has been a nightmare with Enphase inability to monitor the production. There solution is to purchase the new monitoring system for $608 plus labor with no guarantee this will solve the problem.There support team 5 stars has been very responsive however it the same old reply.
I would certainly consider other inverter companies

I purchased four enphase batteries using the SDCP program that just rolled out in California in 2025. According to the contract that we signed, SDCP could discharge the batteries up to 50% daily and send the energy stored back to the grid. However, the batteries have been discharged over 70% every day. When I reached out to Enphase to address the issue, I have been told that a resolution was in the works and should have been completed in about 2 months. After more than 4 months, Enphase is now stating that it will take several months to fix the issue. This is extremely disappointing because Enphase promised by applying through the SDCP program to respect the contractual obligations with the customer, but they're clearly not. What's the point of having a backup system that keeps getting discharged every day? I would not recommend Enphase's products.

Company stands behind its warranty OK replaced defective inverter for free BUT they don't actually fit the replacement for that you have to get an outside contractor. Quoted price to remove defective inverter and fit the free replacement was $1,800!!! So to get ONE non producing panel back on line would cost more than FIFTEEN YEARS of production for the panel.

NOT WORTH ANYTHING

I have the enphase microinverters fitted to my pv panels, and they ARE NOT WORTH A JOT.
my roof is 6.48kw, but these damn things restrict my output to 4.7kw
Nothing but crap, would of expected more.

After SunPower went out of business I signed up with Enphase for monitoring hardware and monitoring service. They installed it in March, it is now May and it has never function correctly. It claims that the amount I’ve exported to the grid equals the amount that I’ve imported from the grid plus the amount that’s produced by my panels plus the amount I’m consuming in the house. My reported consumption equals my actual consumption plus my solar production, so my reported consumption is nonsense. Enphase Blames it on my original installer even though Enphase sent an Enphase Technician over to my house to install the Enphase’s hardware. They refuse to accept any responsibility for it. Enphase’s customer service seems to be completely incompetent. Enphase may make a great hardware, but their customer service stinks.

Enphase Energy has been a solar equipment co. I have been using since my solar was installed and without major problems in the last 15 yrs. I recently went through a complete upgrade because of an offer I took advantage of where I received a large discount on new upgraded equipment that also extended the warranty by 25 more yrs. Throughout the entire experience Enphase sales and support were the best one you could expect in that industry. Thanks Enphase Energy for earning my trust.

I bought Q7 series more than a year ago ... For some reasons we had delays in activating that small pv-system . They are DECLARED 360VA BUT if cos Φ is close to 0.9 IT is NOT TRUE !
So I bought those μinverrer for PV MODULES of 350W but they are not able to produce more than 276W with 1000W/m2. (musurated with Irradiation sensor calibrated from a sensor calibrated in ref chain by Fraunhofer Institute.)

It turned out I had a problem with the app and not the photovoltaic panels, nor the internet!

Great support help 5 stars.However not happy at all with main gateway controller and batteries.Purchased equipment in the fall of 2018,along with expensive battery backup.Intended to purchase additional add on batteries and panels.Late 2020 my approved installer informed me with recent updates I would not be able to increase capacity as new equipment was not compatable with my "old equipment".I would have to purchase another controller and new batteries rendering my old equipment useless.My estimate of breaking even with initial purchase is approximatly 12 years.I did not through more good money into this risky project.I am not a happy camper to say the least.

Slow response to customer issues. I have called and spoke to a rep 3 times for help with a faulty panel. Every time I've been told a remote diagnostic will be done and if not resolved a tech would contact me to set up onsite appointment. HAS NOT HAPPENED AFTER 2 WEEKS! Cannot recommend this company due to poor customer service!

We purchased this home last November and were informed that the solar warranty ownership needed to be transferred within 30 days of closing. We followed the instructions and paid the $199 transfer fee. After living in the home for three months, we received our power bill, only to discover that the solar system hadn’t saved us any money.
We researched the issue online, downloaded the app, ensured the switch was turned on, verified our internet connection, and consulted troubleshooting articles. After following these steps, we contacted customer service. We completed troubleshooting over the phone, but the issue persisted—the gateway displayed "Envoy Failure."
Given that our app showed the Envoy Gateway's limited warranty expiring on November 6, 2026, we inquired about replacing the gateway. Customer service informed us that an authorized installer would need to inspect the system, take photos, and arrange for the replacement. They assured us that installation fees would be covered.
The system was originally installed in 2011, and the installer had gone out of business. Customer service helped us find the closest installer who is 40 miles away. When we called, the installer informed us that they charged a $250 truck roll fee. The installer arrived, inspected the system, and contacted Enphase, who then told that the warranty expiration date on the app was an error—meaning the gateway was not under warranty.
We were shocked and extremely frustrated by this response. This situation is completely unacceptable. Moreover, we were told that the $199 warranty only covers the microinverters for 25 years, not other parts or labor. The installer also explained that finding matching parts would be difficult due to the system’s age.
When we requested an estimate for the total cost of repairs, the installer needed to contact Enphase to determine if the required cables and parts were still available. After three weeks, we received an estimate of $3,200 for repairs, or more than $17,000 to upgrade the entire system.
This entire experience has left us deeply dissatisfied. First, Enphase charges $199 for each ownership transfer without ensuring the system is functioning, effectively profiting from these transfers. Second, despite showing an active warranty on the app, they refused to honor it. Third, their authorized installer charges significantly higher fees—local solar experts offer diagnosis services for $125. Finally, the 25-year warranty on the microinverters feels like a poor value, especially when considering labor costs, outdated parts, and the rapid advancements in solar technology, making repairs increasingly unfeasible.
We hope to have a fair resolution to this matter. My latest ticket number: 17769350

Stay as far away as possible from enphase energy. these clowns will do anything to not take care of their customers and not honor their warranty

Second installation of a solar system. In first used Enphase equipment and was totally satisfied with the performance.

The installers were very fast and very professional. They explained everything I needed to know and helped me with the app as soon as everything was installed. Everything WORKS as promised. I also have an EV and now basically enjoy the energy savings.

Very experienced, knowledgeable and courteous. All went well!

We’ve had solar for a year now. Enphase sent me monthly reports on what i banked and what I used. When we had 18” of snow on the roof they reached out to me to let me know I wasn’t producing or banking any kw and was there a problem. I let them know that all was good just panels covered with snow. It was nice to know that they were keeping an eye on my panels

Enphase was very helpful. They solved my issue in minutes.

The system will not stay connected to the internet; therefore, I can not check on its health or make adjustments. I have had the system for about seven months, and the Gateway has already failed. Tech sent me a new one, which took a week, and I had to find an installer. I live in California and purchased this system due to the numerous power outages. So far, I have had three power outages, and my system has been down during each one. Do not waste your money on this company. I finally had an installer arrive, and he installed the new gateway, and it will not stay connected. My system has not updated its health, consumption, or whether it has been working for over six months.

We didn't have problems with the solar itself. The system with a backup battery worked perfectly. However, we did have a lot of trouble transferring ownership when we sold the house. There is a 30 day window to complete the transfer and they make it 100 times harder than it needs to be. The customer service number is not the in US. This experience is causing us to explore other options for back up energy.
