    Was told YSG is responsible for my moderator not working then I’m told enphase
    Is responsible. I don’t know where to go. I was told when i got these panels that everything is covered for 25 years parts and labor but now I’m told only what’s outside. Can’t get any help.

  • "System is clipping"

    Reviewed Apr 15, 2021

    Last November I had a system installed consisting of 16 LG 340 watt panels with Enphase IQ7 micro-inverters. So this is a 5.5K system that maxs out at 3.9K. A month ago the system started clipping. At 9am my production flat lines until 3pm. As far as I can tell I am losing 2-3 kWh per day. If you multiply 2.5 kWh by 182 days that is a huge lose of power ie: MONEY !! As this was a financial investment for me I want the maximum return on money as possible. I am dissappointed in my installer, Solarmax as they do not have the balls to confront Enphase. Enphase is totally unresponsive and unwilling to admit there is a problem with their product, telling me just to be happy that do not have an electric bill. This is my 2nd system. I previously had a SolarEdge inverter and was much more satisfied with their product than the Enphase string inverters. I do not recommend Enphase, there are better options.

    "Worst customer service ever!"

    Reviewed Mar 09, 2021

    I have had solar on my roof for over 10 years now. The first generation Enphase inverters did their job and started failing as expected (after 9 years). Lucky for us this was right as they came out with next generation technology. I had all inverters on my roof replaced. 2 days after install 2 of them failed. My installer was received 2 replacements, but Enphase refuses to pay for the labor to have them installed. Due to having a 3 story house next to a public park, this makes the install both dangerous and expensive. Enphase says the the warranty covers replacement parts and that labor is up to the "independent installer".

    I am stuck paying double for installation due to their faulty equipment. I have not done research on new solar installs, but if you have options - check them all out before getting stuck with Enphase.

  • "Not a good experience"

    Reviewed Jan 08, 2021

    We installed solar panels in November, having issues with productions since the first week and they have no worries to fix it, all the time saying we need to wait. I have 4 to 5 panels do not producing the correct energy, and they have no intention to change the panels. Nobody call to check with us if everything is ok. Ignacio was very helpful with us, but we understand it is not all in his hands. To him 5 stars, very helpful and kind and always there for us. Feel bad for this review, but we do not want other person have the same issue.

    Reviewed Aug 18, 2020

    We installed a ~12kW REC Group Solar system with Enphase IQ7A Micro-Inverters in July 2020. I have been very pleased with the usage of the system. The iOS app and website interface works really well and is easy for me to navigate. We have some shadowing on the roof in the morning because of a chimney. This Enphase system ensures all the panels are maximizing the production. The system allows for expansion and upgrades in the future, if I so choose as well as adding a battery if that becomes more financially beneficial in the future.

    "Enphase Energy makes high quality equipment"

    Reviewed Jan 13, 2020

    I've had my solar energy system for a couple of months and here's what I like about Enphase Energy:

    - The ability to see the daily, monthly and yearly energy production by the solar panels
    - Simple to use web site
    - Ease of configuring the WiFi settings (see below for the Dislike on why you might need to do this)
    - The combiner box will store up to 2 weeks of data when it goes offline

    - The combiner box really, really does not want to be on an extended WiFi network. Very incompatible. Only use your main 2.4Ghz WiFi network when configuring the combiner box.
    - When the combiner box is offline, the web site does not refresh

    Good luck with your system! You'll really enjoy it!

    "Marginally Competent Administration"

    Reviewed Oct 30, 2019

    I will convey the facts as I experienced them and you decide. I purchased a home with solar and enphase IQ1 inverters. The inverters were so unreliable the installer stopped working with enphase equipment. As a new owner, I chose to upgrade to the reportedly more reliable IQ7 inverter in late October, 2019. When I bought the equipment, I sent in the change of ownership form. Unfortunately, the change of ownership was not recorded correctly or in a timely manner so when they filled the order for the new inverters, they emailed the credit card receipt of over $2000 to the old owner and the delivery name on the order had my first name and the previous owner’s last name. Some dayslater I get a call from a transfer company at 10AM who is in front of my home wanting to deliver the inverters. I was out of town as I had no notification of shipment or expected delivery. I get another email from the old owner who received another enphase email, timed 11:36AM same day, that the hardware has shipped. Remember at 10AM, it's already at my home. I called several departments in enphase to correct the ownership name and document problem and was told the departments don't talk to each other. The upgrade department doesn't follow through on what is sold and said I have to talk to Customer Service. Calling Customer Service, I get the technical department. Calling the Operator wanting to talk to management to correct this situation, one CSR has trouble with her phone and I get disconnected. Calling back, I get someone who says she has "no way" to reach management and I can leave my name and number, which I had done earlier in the week with no call back from management. And did I have a case number? I have spoken with four people and was never assigned a case number. The management and administration within this company scares me and it should scare you as prospective clients. As I told two of the folks at enphase this morning that I spoke to, I hope their new inverter hardware is better than their administration. After days of pursuing this, I still have not been able to talk to management and don't know if anything in my account/records has been corrected. I warned the old owner to expect more emails from enphase. You decide if these are the folks you want to deal with.

  • "Excellent customer service"

    Reviewed Jul 13, 2019

    Placed an order of 34 panels/microinverters and confirmed it could be delivered into the garage.
    When the truck arrived, the driver was unable to remove the order from truck with the pallet mover. Driver explained order had been loaded with a fork lift. And if removed, the driver would only leave the 1500 lb plus deliver at the curb.

    Called Enphase customer service. Even though Enphase does not directly ship or arrange for shipping they immediately took full ownership of the problem. They advised not to accept the order as it was not my responsibility to take apart the order so the delivery person could remove from truck They (Adam, Aaron, and Jae'l) worked diligently to work on solutions and arranged for the shipment to be diverted to the installer so everything could stay on track. They even offer to credit me for the frustration. This was an excellent example of how customer service should be done.

    "Easy Installation, Horrible Software"

    Reviewed Apr 09, 2019

    I went with Enphase due to the desire to not have an inverter in my basement. The installation and setup were super easy and pain free, however I've had issues with their software ever since it was installed. Mainly, their software does not calculate the home energy usage accurately. I've checked it against my energy bill every billing period and it is never accurate and is never, what I would consider, in the ballpark. Given this error, I have no reason to believe the energy produced number is accurate either. So basically I have no idea how much energy I'm using nor how much my system is producing. Would not recommend based on this lack of information.

    "Installers certification and training"

    Reviewed Sep 06, 2018

    Training is imperative on any kind of customer service company, without proper training customers will not get the service they deserve, lack of training to me as a customer is like a slap on the face. I asked the installers if they were certified to work on Enphase equipment, specifically on the IQ + series, and they told me yes, come to find out Enphase don't certify installers. I now have to go find all the answers myself because the company that installed my system couldn't even install the consumption CTs or upgrade my software. I ended up doing the installation, consumption is just as important as generation to me, it is a key factor in saving energy which is the primary goal of PV system owners. Enphase don't seem to think so. To get consumption you have to get CTs installed and upgrade to Enlighten Manager for a total of approx. $500.00 additionally on top of everything else. The sales person never mentioned this, in the contrary he said monitoring was included with the Envoy IQ series. Enphase tech support have been doing an excellent job, in my case, those guys know their stuff real good and I can get my questions answered. The system overall is great the micro inverters output average is the same, they are rated at 290 Watts max and I have seen them go up to 280 Watts on a July sunny day. the Envoy IQ series is doing great, a little slow communicating but as far as connection is good, there have been a few disconnects but not to often and I can live with that. The software still need to be polished. Enlighten software allows you to monitor and generate reports of your system's performance and overall condition. The only thing I'm having difficulties with is actual consumption calculations. I had to install the CTs as I mentioned earlier, but took me about a week after system activation to get them delivered to my house, now the generation and consumption are our of wack, so I have to get accurate readings from the meters outside, I wish there was a way to make an accurate adjustment within the software, so far the only thing you can do is adjust the date on the software and that is not accurate. The panel level readings are not actual power output like in the Installer's toolkit app, is the total power produce over that day. I would like to be able to monitor actual per panel level output and not the total accumulation per panel, it be better if I could get both. I hope this helps.

    Our installer recommend Enphase S280 microinverters for our PV system due to an unavoidable amount of partial shading. After researching, we agreed it seemed like the best option for our system. We have never had an issue with our system after a year and a half of operation. I love the monitoring. I do not check it everyday, but it's interesting to check in every month or so.

  • "Poor service "

    Reviewed Nov 30, 2017

    As an engineer with manufacturing experience, I think the module price is quite reasonable. I have 21 M190 inverters installed January 2011. Other than occasional issues with envoy communication and problems getting the inverter list to properly match the array in enlighten, the system worked well for the 1st 5 years. I have had 4 inverters fail in the last 2 years and have an outstanding RMA on a 5th. While this is not good reliability by any measure, so far replacements were all done under warranty. The issue is that it can take months to get a replacement. Sunetric (RGS Energy) says Enphase requires them to log an RMA request and wait for a replacement unit. While I have had some issues getting Sunectric to be responsive, the bulk of the delay appears to be Enphase - they are not consistent, sometimes responding quickly, and sometimes taking 3-4 months to send a replacement.

    They offer individual panel monitoring, but the costumer didn't get that access. Only the installer get individual panel monitoring. I pay more for those, but didn't received what was promised by the installer. They told me that it was an issue with Enphase where they restricted that access to costumers. Now I am planning to expand my system, but use power optimizers with a single string inverter.
