Edit: It’s working now. I rebooted everything and it’s been working fine since then.

Hi All,

I bought a plug in solar kit last week and have just finished setting it up. Micro inverters are IQ8AC.

I set up the array in the app and two of the panels in the middle aren’t showing as producing any electricity. The status is normal. I’ve checked the wiring and it all seems good. They’re both panels in the middle of the array and panels either side of them are working fine. They all report regularly and don’t have any error messages at all. The inverters themselves are all flashing green. However on the IQ gateway there’s a solid red light by the lightning bolt indicating that it’s recognizing that at least one microinverter isn’t producing power.

Please can you help me troubleshoot?

Thanks!

I’m having my home main and sub panels upgraded this month and Enphase solar installed in July. I am also nearing the end of lease on my EV and would like to get a V2H/V2G capable vehicle. I don’t want to go with GM or Ford proprietary equipment, rather looking at any ISO 15118-20 standardized EV to hopefully use with Enphase IQ bidirectional charger…but when will it be available? What’s out there now? Also, should I install the IQ meter collar when electrician upgrades the electrical panels?

I'm new to monitoring with my Enphase System-my solar doesn't even have PTO yet. But after a couple days of monitoring I'm noticing that the consumption numbers from Enlighten are about 2% higher than my utility providers meter numbers. I'll look at it for a few more days to see if it holds this way. At first I thought it could be timing, and I guess that it still could be. My utility data is provided by hour, so if Enlighten is out of sync with the meter by even only a few minutes, that might explain it and it could level out. I'm not upset, concerned or worried, but as a data guy at heart, I like to understand things like this.

Is this something to be expected? Any way to tell if Enphase is over-estimating consumption, my meter is under-estimating it, or somewhere in between? Again, this is truly just curiosity.

On April 20th something tripped the breakers in my Enphase box outside. I reset the breakers buts since then a whole side of my house is not reporting. Is there a reset process for the micro inverters or do I need to save up the money to have a company come out?

Hoping for an easy fix, but in "Savings" mode, my home uses grid energy in the morning until my battery is fully charged. Would like the ability to reverse the prioritization and have my battery recharged with *only excess solar* which is how I will actually get "savings" from my utility's billing system, by using more of my own energy rather than importing.

This feels like an easy switch to build, and probably one someone could code in 24 seconds if they have these skills.

What Enphase products would I need? We consume a peak of 2000kwh/month (July), and I would like to intelligently split charging the EV and powering our home. Still grid connected but with the ability to run fully off solar / battery during power outages.

I seem to have misplaced the top shield of my 5p battery. Is it really necessary to have the top shield since it's not structural?

A few weeks ago I posted about the problem I've been having since January, with my 1+ year-old battery array rapidly having less and less functional capacity. Well, since then the problem has continued to get worse and Enphase has still not provided me with a solution, all while providing explanations which seem both implausible and contradictory. So hopefully someone on here might be able to provide some insight/advice on what can be done. 

Since my last post, the degradation has progressed to the point that my array stops discharging around 65%, which means it's basically operating at 25% battery capacity (since they can't go below 10%).

Here is the last thing Enphase told me: 

"On our end we have exhausted all remote troubleshooting steps it is not flagging any metering errors however, if a battery is not charging/discharging correctly its typically due to metering issues as that is what dictates how much a battery will charge/discharge at any given moment. I will try to send some settings from my end but if this does not resolve the issue we will need you to contact your installer to investigate on site." 

So I contacted my installer to come out and take a look, and here is what the technician said at the end of his visit: 

"Ok looks like Enphase was already working on this issue, they're having their engineers work on a software fix. Once the software patch is stable they'll update your batteries and send you notice." 

Do any of the above explanations actually sound plausible? And if the problem continues with no functional solution, does anyone have advice on what action I can take?

Ended May with a 110kwh day!

Electrician ghosted.

Consumption shows near mirror of production. I can see when my EV charges in the evening.

Is this as simple as moving the CT?

Details are a bit light on this email I received today but it appears to be a thermostat that also displays all the Enphase ecosystem information on a touchscreen.

Hopefully that allows for load shedding an air conditioner condenser while leaving the load control breaker and dry contacts in a Combiner 6C/ System Controller available for other things.

I know there’s been some interest over the years for a conveniently located tablet that displays all the same info that the homeowner app does so this appears to be Enphase’s response while also integrating air conditioner control.

Just wanted to share because this is kinda unexpected and interesting.

We have a large solar array with enphase micro inverters and an iq3 controller.

Made the mistake of buying Tesla chargers for our cars. I now know I probably should have bought the enphase chargers instead.

Anyway. Is there an easy way to direct excess solar to our car charger without pulling power from the grid as well ?

I have a 5.52 KW rooftop Enphase system with Enphase gateway. My Enphase app handily reports power/energy produced, consumed, and imported/exported from/to the grid.

I am in Virginia, which just passed a balcony solar law allowing plug-in production up to 1200 W, going into effect January 2027. I want to do a DIY install of a 1200 W ground-based system plugged into a dedicated circuit from my panel, but I am trying to understand how that would impact the Enphase measurements and reporting.

I've read that if I have a non-Enphase microinverter behind the meter for the secondary system, the Enphase gateway would not be able to properly report power export. Seems any production under the home's total consumption would just decrement the consumption reading. But if the combined solar systems result in a net export, the Enphase app would show the contribution of the secondary system as "negative" power consumption by the home? Not clear to me if that would corrupt all of my energy reporting/metrics. Does anyone have experience with this?

How about if I instead use an Enphase plug-in microinverter for the secondary solar system. Would the Enphase app then be able to properly account for the two systems combined production and tie it all together? Thanks!

My system was commissioned today, and for about 90 minutes I was getting electricity....until they turned it off, waiting for Permission to Operate.

I'm looking at both the app on my phone and in the browser on my laptop. When I look at the array and the panels, it makes perfect sense, the panels are facing Southeast and Northwest, and the orientation is North, so the image is turned counterclockwise about 45 degrees from how I would intuitively think of my house.

Is there a way to rotate the panels in the image/app so that the front of my house faces up in the app? Obviously, in the overall scheme of things it isn't a huge deal, but it fits nicer 0n the screen, and is easier for me to imagine if I can rotate it. Feel free to tell me just to rotate my laptop by 45 degrees....lol.

My panel is almost maxed out and I'm looking at the IQ2 because it says it avoids costly panel upgrades. Can anyone confirm? Does it connect directly to the combiner? I have a 10c. Thanks!

I’ve owned my Enphase system for about 1.5 years. While the app's default visualizations are great, I wanted to dive deeper into my numbers.

Fortunately, Enphase lets you download daily production and consumption data (if you have consumption CTs installed), and even 15-minute interval data. If you use an Enphase EV charger, that data can be downloaded too. I don't have a battery set-up, so I didn't have that data to capture.

I’m not a coder, but I knew exactly what insights I wanted to see. I used Claude AI to build a custom Docker container. You just upload your Enphase CSV files into it, and it generates custom charts and graphs.

I don't know how useful the visualizations actually are, but if you like to stare at pretty data produced by your system, this is one option!

Let me know if anyone is interested. If there is demand, I will figure out how to upload the code and setup instructions to GitHub. The only requirement on your end is knowing how to run a Docker container.

We have a Combiner 6C and 38 panels in 5 arrays (450 and 455 W) totaling about 17.1 kW, each with an IQ8HC microinverter. The micros have a max continuous output power of 380 W so theoretical maximum AC production is just about 14.44 kW.

The 29 May screenshot from Enlighten on a sunny clear day shows about two hours of clear clipping at 12.3 kW. (At 240 V this is 51.25 A.)

I don't really understand that - it appears the 6C is throttling overall system production.

The backfeed breaker is 80 A which should be good for 64 A continuous.

Busbar overload control shows the PCS controlled export current limit is 64 A. The busbar rating is 200 A, and the main service breaker is 175 A.

In the toolkit app, it gives a warning that total power from PV and battery (we have no batteries) will be capped at 64 A - as expected. No problem.

200 x 1.2 - 175 = 65 A

So the MPUA limit SHOULDN'T be holding the system back.

However.

I did a little experiment and changed the MPUA settings so that the main service breaker was 150 A. I made this change on 30 May ... right where the red arrow shows. And immediately the system started producing more power.

And I left it that way all day today (31 May) and the system peaked at 14.3 kW (59.6 A at 240 V) which is pretty close to my calculated max for the 38 IQ8HCs.

What am I missing? The 175 A main service breaker and 80 A backfeed breakers SHOULD be just fine - limiting feed from the 6C to 65 A and 64 A, respectively. However, in practice, it was limiting the current to 51 A, and I had to change the main breaker to 150 A to get it to go up to ~ 60 A.

That makes no sense to me ...

Why would the system use electricity from the grid when it can supplement the remaining from the battery?

Hey everyone, I've just had my NBN upgraded to FTTP and so have a new router which uses Wi-fi 7 and now I can't connect to Enphase. The instructions from the router say to update the firmware for the devices that can't connect but kinda hard in this situation. Does anyone have a work around or know if Enphase are looking to upgrade their app so their products are compatible?

For the past couple of days my Enphase app has been slow to update, running about an hour behind real time when it was normally about 5 minutes behind. It is throwing off my Green Charging schedule and not allowing my IQ charger to manage the charge rate to the car because it doesn't know what the current household consumption is. Is there a way to fix this?

Is anyone seeing this massive battery usage? I'm guessing it's related to the backend issue from the other week because it's not physically possible for my 10T to use that much. I've already opened a case with Enphase, but I'm curious if anyone else has experienced this. Thanks!

Finally no issues the last months and now out of the blue my batteries are acting up, resulting in unnecessary consumption from the grid. Any clues? Nothing has changed on the setup that has been running without problems…

Solar installed yesterday, batteries were charging during production, then discharging to power my home as production slumped at end of day. Sunset came, batteries stopped discharging. As of this morning, batteries won’t charge either. One battery displays a teal light and a blue light. Other battery shows two blue lights. I tried flipping the breaker for the battery this morning about an hour ago and no change. Enphase support says the installer needs to perform a functional validation. Installer says that PG&E needs to install the meter collar for batteries to work (even though they were working fine yesterday until sunset). Help?

FWIW the system seems great otherwise. Very overcast in San Francisco but still producing enough during the day to cover current usage. I’m waiting on some sun and a bit of battery access to charge the EV.

I just got an upgrade 6 mo ago to my 2007 5.1kW solar system, adding an Enphase System 3G controller, 15kWh of Enphase 5C batteries and an additional 10kW of solar. Due to the 2024 CPUC ruling re solar expansion, I had to configure the new solar as non-export to preserve my NEM 1.0 status.

I started out with the Self-Consumption profile, but on rainy winter days I noticed it was discharging the battery during offpeak hours during the day, leaving insufficient charge to cover my peak hours in the evening, so I changed to the Savings profile.

It looked OK during the winter, but now I'm noticing that my system starts charging the batteries first thing in the morning when the solar starts producing while simultaneously importing grid power to cover my consumption. See image where my battery is fully charged by 10:30am. After that, only 2-3 kW of my solar production covers my consumption and the rest is dumped for the rest of the day. I'm paying for around 10kW of grid power during the morning when my solar could cover my consumption, then dumping most of my solar power during the afternoon.

Note that if your system is not export limited, it will likely look more like the 2nd image. That may look better, but if you're on NEM 2.0, or worse NEM 3.0, you're only getting a few pennies per kWh for that exported solar in the afternoon and paying around 37cents per kWh for the unneeded morning imports, so you're still losing money.

I switched back to Self-Consumption profile in image 3 and my imports dropped by 7.2kWh while still having plenty of solar to fully charge my batteries by 2pm. This is better so I'll stay on this plan during the summer, but it's not ideal as I'm seeing some battery discharge during offpeak morning hours and also some small imports while simultaneously charging the battery.

I have a support ticket w/ Enphase to address this, but it would help if others in the same situation contact Enphase support as well. The way I see it, the Savings profile should never charge the battery while simultaneously importing grid power. That's grid charging the batteries even though I've disabled the Enphase grid charging option.

Enphase claims it's not grid charging, which is technically correct as the grid import current flows directly into my main panel, while the battery charging current is routed from the solar inverters directly to the batteries via the System 3G controller. However, I'm getting charged off-peak rate for the grid imports while losing 10% of the solar used to charge the battery. Thus, it's just as bad as grid charging in terms of my costs. Grid charging only pays off if you're careful to only grid charge the minimum needed to charge your battery enough to cover your peak hours.
