Do NOT buy Enphase 10C batteries

So, about a year ago we had a 43kw ground mounted solar system with three 10C batteries installed. My installer was phenomenal. About a few months after the installation, we had a myriad of errors with the batteries. They ranged from the batteries not charging appropriately to various other issues. A few months ago, during a site visit from Enphase, it was discovered that rodents had chewed through the internal wiring of three of the battery modules. Apparently, the mice entered through a 1 inch gap on the rear of the 10C batteries. The batteries are mounted on a rack outside my home. All the specs for the batteries indicate that outside installation is okay and there is no bulletin or warning against rack mounting. Enphase also sells on their website, an accessory for ground mounting the batteries. So, unless you mount these batteries directly on a wall, which would cover the 1 inch gap in the back, it allows for critters including rodents entry into the internals of the battery. If you do a google search, there’s indication that these batteries are not “critter proof.” As a matter of fact, a mouse can enter in a space that’s only 1/4 inch wide. Why would any company design a product to be utilized outdoors and leave a 1 inch gap for potential intrusion by rodents? And to top it all off, their warranty doesn’t cover “biological intrusion.” That’s akin to a vehicle manufacturer leaving a 1 inch gap on the sunroof of a vehicle and stating we won’t cover water damage when it rains. Did Enphase not realize that their battery design practically invites rodents in since it’s a warm environment inside? They effectively allow them easy access through the 1 inch gap in the rear of the battery enclosure. After two months of back and forth with Enphase, whether they we’re going to do the right thing and cover their product which is inherently flawed by design, we were offered a “discounted price” of 2K for replacing each module. So, a total of 6K for 3 battery modules. Wtf? We’re being required to pay for a company’s terrible engineering. So much for a company doing the right thing and standing behind their product . I’m hoping to educate others who may be in a similar situation and DO NOT recommend anyone purchasing Enphase 10C batteries for the above reasons. I would recommend the Franklin Apower batteries as they’re completely sealed and appropriate for outdoor use unlike the Enphase batteries.

Great for Shaded Roof

My roof is less than ideal for solar. I have panels on three roofs. One smaller array of 3 Qcells Q.tron 430s over the garage which has seasonal shading from my 2 storey Vermont home and one array of 12 on the second floor facing a less then optimal east-northeast direction with very little shading from trees. On the south-southwest second floor roof the 11 PV modules are shaded in the fall, winter and spring from trees. The Enphase IQ8MCs mounted under each PV module do a great job at maximizing the solar output in various conditions. They work well in cloudy conditions as well as clear days. So far the arrays are exceeding the original estimates by 20-40% each month. The panel level monitoring is probably the best available. During the installation it was determined that one IQ8MC was faulty and the installer contacted Enphase and were quickly shipped a replacement that was installed while waiting on the go ahead from the utility go live for net metering. No problems since and it is nice to know that Enphase and my installer will work quickly to address any issues that arise during the 25 year warranty period.

Great customer service.

My unit quit communicating with my modem and the company that installed it only gave me pages of confusing instructions on how to re connect to the internet or they offered to send out a technician for $150.00!!!! I worked on it for hours with some support from my cable company to no avail other than super frustration. I contacted Enphase customer support and within 10 minutes I was up and running. Thank you Enphase

BAD SERVICE!

WHERE DO I START! THE CUSTOMER SERVICE HORRIBLE YOU CAN NEVER SPEAK TO ANYONE. THE RESPONSE TIMES ON CALLING OR CONTACTING YOU BACK IS OVER WEEKS. WE BORUGHT A HOME AND NEED OWNERSHIP TRANSFERED OVER. THEY ARE GIVING UP THE RUN AROUND AS WE HAVE PROVIDED ALL THE NECESSARY PAPERWORK REQUEST. WE HAVING EVEN GOT TRANSFERED WITH THIS COMPANY YET ON OWNERSHIP OF THE BATTERY SYSTEM TO OUR HOME. WHEN THE CUSTOMER SERVICE IS LACK YOU KNOW THE BUSINESS WILL WON'T BE GOOD EITHER. DON'T GET ANY BATTERIES SYSTEMS FROM HERE THE CUSTOMER SERVICE IS BAD!

Battery failed within 5 years; Enphase service is terrible.

Installed a system on 17 panels and 5 batteries. One battery failed after having the system for about 5 years. Enphase service runaround told us to get installer to diagnose. Installer said would cost $300 for site visit. Enphase told us we needed to have the installer electrician come out because they didn't have any technicians in our area. The installer called Enphase to confirm that they wanted the installer electrician to come to the site, even tho a technician had not come. Enphase confirmed that they needed the installer to come to the site. Once at the site, the electrician diagnosed the battery failure. Enphase said that they needed the technician to see the system before they'd accept the diagnosis from the installer electrician. The installer spent the time at our site on the phone with Enphase, who gave him the runaround. Enphase told us WE needed to pay for the installer electrician, since we didn't have the technician come out first. Nevermind the prior conversations. All of the Enphase phone support is from India. They seemed sympathetic to our issues, but the upper management holds firm in their nonsense. So we are out the $300 for the installer visit, the technician finally came after 4 weeks of us trying to get him to come, and now presumably we need to wait for the electrician to return to confirm the diagnosis from the technician. Who knows when or if we'll get the lemon battery replaced. The installer said "almost no one" is installing Enphase systems anymore due to reliability and issues like this. Everyone is going with Tesla... Wish we had, for sure.

The Complete System Better Than I Expected

I started with a grid-tied system with Enphase microinverters, solar panels and a Combiner 5C. As I learned more about Enphase products and how well they integrate with each other and the Enphase app, I added a System Controller 3G with programmable load shedding, three 5P batteries, an EV Charger 2 and a Kohler backup generator to recharge the batteries as needed during a long grid outage. Now it's a completely automatic whole home backup system that's fully visible and controllable from a single integrated phone app or computer webpage. The data displays and export capabilities are great, including EV charging. I ' m very happy with the system and Enphase support, both corporate and local certified installer. If I were to replicate this capability a few more years down the road, I would consider paring a compatible EV with an Enphase DC bi-directional EV charger instead of the backup generator. I didn't want to wait that long, and am glad I have the extended grid outage capability now, with the generator.
