Anyone with ideas on why my solar output would clip randomly? This has not happened in 5 years of usage but over the past few months I’ve noticed days where the solar is clipped for some reason… good day vs bad day photo attached. Both were sunny so output should’ve remained high.
Only thought I have is that the grid is frequency shifting to cut my IQ7’s output… just want to make sure it’s nothing wrong with my system.
I am the same dude who had the Gateway & IQ 40 connection issue earlier this week. I have another issue that arose due to the storms that rolled through last night here in Michigan and am wondering if anyone else is experiencing this.
We lost grid power last night and are running on batteries right now. I noticed that when the sun came up, there should have been plenty of power for the panels to take over, power the house, and recharge the batteries as they have done before in the same situation, but they were producing between 0 and a measly 0.1 kw. They should have been pushing 3kw by that point around 10:00am based on my close observations over the years. (I should note, the grid came back on last night briefly around 9pm and the batteries were at seventy-something percent. Then this morning the grid went down again when a transformer blew down the street in a rather dramatic and audible fashion.) This continued for long enough that I was concerned, so I called Enphase.
Note that I did my own diagnostics in the meantime. No breakers were tripped. Gateway lights all green. All equipment green status in the app. No breakers open on the main panel. Also, when I created high demand by powering on a small window AC, the micros' output jumped to 0.4w for a brief moment before dropping back off to fluctuating between 0 and 0.1w. The woman at the call center tried her best, said there were no relays that needed resetting or anything else wrong, and after an hour on with her, mostly on hold while she talked to a Tier 2 tech presumably, she told me the following: there was a recent firmware update that requires the battery to drop by some percentage (she said 10%) before the panels will kick in during an off-grid outage. This seems... odd. She said it is a new feature designed to prolong battery life?? I wasn't totally following Either way, here I am at 50% SOC trying to drive it down to 47% when she says the panels should kick in. She is actively monitoring my system and will call me if they don't. Supposedly. None of this really makes sense to me.
So a couple of things - is this new firmware feature accurate?? If so, WHY would they do this? In a grid outage, especially let's say it's prolonged and not very sunny, we need every watt we can produce and store. Even if I have 98% SOC on the battery, the panels should kick in if there is enough to produce.
Confused and frustrated over here. Anyone have any similar experiences?
Enphase was very impressed… Text [When homeowners have access to their energy data, a few can’t help but get creative with it.

Hi,
I bought the (AC) IQ EV Charger 2 (IQ-EVSE-EU-3032-0105-1300) because it was advertised as supporting bidirectional charging. At the time, Enphase support told me that the hardware was already capable and that we were only waiting for a software update.
Now I've noticed that Enphase has removed most of the information about bidirectional charging from its website, which is very concerning.
What is the plan, u/Enphase_Support_Team? I sincerely hope that if the current hardware cannot support the promised bidirectional functionality, Enphase will replace it free of charge. Many customers purchased this charger based on that promise.
Is Enphase planning to offer a free hardware replacement for IQ EV Charger 2 owners so they can access the new bidirectional charger when it becomes available?
I feel like I'm missing something! We've got the usual system that monitors import and exports but its not lining up in our electric bills. We are basically always being billed for more than what enphase says we're consuming, and I have gone through the numbers day by day. When we lose power (and the panels go on and off with the internet, how do you fix THAT by the way?) we have a gas generator so that shouldn't cause so much difference. The discrepancy has been off by hundreds of kWhs. Anyone else experience this? Is my power company being sketchy or am I looking at a hardwire fault? Ahh!
Hi! We just closed on a house that has a fully paid 12 panel Enphase solar system. The previous owner was quite old and I don’t think he cared about anything more than just getting power but I love data and details and have a robust smart home system and I’d like to add solar tracking and monitoring to my system.
What’s my best option? I have no idea who installed it but I do see Enphase offers some options for a gateway and system monitoring on their website however I’m curious if there’s a better option or how much their solution would be.
Thank you!
Finally got everything up and running, things were looking great. And then we had a power shutoff event, and none of my batteries kicked on. Inside the Enphase app grid status was listed as "Unknown". After power came back I had to reboot the system to get it to recognize the grid power and get my backup circuits turned back on.
After an hour so of Enphase support, they recommended I contact my installers, which I did. They're not the most punctual or responsive people in the world, so I've been digging into what might be wrong. After the back and forth with Enphase, my app stopped reporting exporting any power. It's not really reporting importing power much either but I think our batteries are just getting us through the night.
Last week, it looked normal.
Is this likely a CT clamp / wiring issue? Something I could potentially fix myself?
*Edit: adding some extra graphs.
First day we had some outages, went out about 3 times. Once at 3 am, a little later in the day ~4:15, and one last time for the rest of the night around 8. Never had a "grid outage" indicator on the graph.
Next day, more high wind events. Every time power dipped out and came back, I had to flip the switch under the gateway off and back on to get it to recognize the grid.
And finally, the day I was on the phone with Enphase and they were trying stuff. This is when exporting looks like it's no longer counted.
At one point support had me manually flip the "off grid" switch in the app, which would take down my backup circuits and then ALSO wouldn't let me flip it back to "on grid" in the app. Had to reset the gateway.
I have a highly energy efficient new home R60 ceiling R28 walls, Alpen glazing, my TOU records show only a very small 2.5 kWh total usage during the 3 hour peak load window (4pm-7pm) so I want to install a small 5 kWh battery that will shave off this 3 hour load. With this peak load gone I can sign up for the cheaper TOU rate plan.
I’m looking at a simple TOU load shedding system with a 5P battery and combiner box. Not for grid backup.
My house has WiFi (Starlink) but no cell service from ATT or Sprint.
I have read conflicting statements about this grid tied system needing both WiFi and cell service.
Yes, it’s needed on the 10c grid back up systems, but no on the smaller 5P Grid tied system.
Looking at the Enphase Planning guide, page 48 section 9.2.1.1 shows this simple 5P battery only TOU system.
Any thoughts or suggestions or warnings you fine folks have for me? Thanks in advance.
Earlier this year I had three IQ 10C batteries installed. I expected some efficiency loss, but the delta between discharged and charged implies a 41% loss. Is that normal or to be expected for these batteries?
Are there any practices recommended to avoid round trip battery waste? Right now I have the system in "Savings" mode.
When I bought my solar energy system in 2023, I didn’t really care about having backup capability since we rarely have power outages and I was trying to save on the cost of the system.
Now I think I would like to add it in case a major earthquake causes an extended power outages (I’m in LA and Venezuela got me thinking!)
I have 15 400W panels, IQ8 inverters, and a 10T battery. I know I need to add a controller, I am trying to decide if I should swap out the 10T for a 10C battery. The old battery has a 15 year warranty so plenty of life left, but I believe the 10T has more power. Probably the biggest power draw would be AC and not sure the 10T would cut it.
What are your opinions?
To give some background I have the Enlighten app tracking my solar usage. I live in a city that offers a credit program to additional production exported to the grid. I understand that top level numbers will not match as my home will take power from my Solar first and that usage will just never be known to my utility but my expectation that the Imported value from Enlighten should match my usage from my utility and that the Exported value from enlighten should match the credits on my bill. Is this an incorrect assumption as these numbers have differed WILDLY for the past 6 months since installation.
I've been looking at eBay and elsewhere for used microinverters since they're so expensive new. Will used microinverters still physically work?
I'm a Residential customer that just got my new system a month ago. Previously, I was asking a question about my system and someone told me I could do what I was asking myself using Enlighten Manager, but I would need to get my Solar PV Installer Certification. I just finished! If I want to be co-manager of my own system with my installer, what's the next step-do I tell my Installer, tell Enphase or both. TIA!
This is an update to my previous post here:
https://www.reddit.com/r/enphase/s/EMkQpVHsIT
So, a couple of things I'm assuming resulting from a hotfix that was pushed out today:
My IQ 40 is officially connected to the Gateway, yay! I didn't have to do anything. It's connected.
The "Battery Assist" option for the EVSE Green Charging mode is gone. I'm happy about that. It seems silly having a battery charge a battery and there is a lot of loss between the DC/AC rectification cycles. (I have yet to test if the battery is drained overnight if the overall system profile is Self Consumption, though... If so, I get it, but I hope there is a way to prevent the battery from being depleted charging the car overnight.)
Green Charging mode is... Totally broken in my instance. We had abundant sunshine today, and I left my car plugged in all day. It didn't send and power at all. Never kicked in even though we had hours of excess production to the tune of 6,000+ watts. I tried plugging it in multiple times. I powered off and repowered the EVSE. I tried both of our cars, one of which has a native J1772 plug. Didn't work. (My vehicle has a NACS, so it's adapted.)
My system reports that Dynamic Load Balancing on the EVSE is disabled. Enabling it requires installer access. The new AI assistant in the Enphase app assured me that having it disabled shouldn't matter. However, the dynamic load balancing seems like it would be useful regardless (maybe quicker scaling at those 8 amp intervals??). Also, seems like there are overlapping duties between the standard IQ 40 load balancing operations built into the hardware (ie those 8 amp intervals), so seems possible that's where the bug is.
One step forward, one step back... At least the green charging mode used to work before the patch, albeit woefully unreliably due to the gateway not connecting to the EVSE.
Calling u/Enphase_Suport_Team again! Getting closer, guys.
[This is a long post, feel free to jump to the TLDR at the bottom.]
I first installed solar with 28 Sharp 245W panels in 2010. Got PTO from PG&E under NEM 1.0 in January 2011. The 14 D380 experienced many failures, and were replaced by Enphase with 28 M215. The warranty on the M215 expired in 2025 - it was backdated to the original purchase of the D380, and there was only 15 year warranty at the time. I have had many M215 failures over the years also, and have a number of IQ7-M215 as a result, not sure how many.
In 2023, I added 42 more panels with 28 IQ8+, just before NEM 3.0 went into effect I'm now on NEM 2.0, and grandfathered through January 2031. The main panel had to be replaced with a 200amp PVL panel, with a 100 amp PVL bus. The PV is 23.2 kW DC / 18.2 kW AC. Actual all-time peak PV from my Home assistant real-time curves is 17,200W AC.
I don't have a sizable electric bill currently - the PG&E NEM charges and SJCE excess generation credits roughly cancel each other.
However, I live in the hills, in an area where outages are getting more frequent. Typically, it is drunk drivers knocking down poles, at nights, on weekends or holidays, and PG&E takes forever to fix them. I also had 2 short ones in the last week alone that are unexplained. I'm looking to add in some backup batteries as I'm getting tired of the outages. Currently, the IQ8+ are not configured for micro-grid due to the mix with M215. Solar micro-grid alone is not very useful anyway given that most outages have happened when the sun doesn't shine.
I bought a 2025 Equinox in EV LT1 August 2025 to replace my 2015 Volt before the EV point of sale rebate expired. It is V2H capable, but maxes at 9.6 kW, which would not be sufficient by itself for backup - there are sometimes consumption peaks above 20 kW per my Home assistant Eagle3 real-time grid demand curves. Typical is of course much, much lower. The Equinox has a huge 85 kWh battery, which would be a massive bonus if compatible, requiring far fewer IQ batteries.
From what I have gathered, the recommendation from Enphase is to upgrade the 28 M215 to IQ8-60. They have provided parts quotes for this under the program program. The benefit would be to run all 70 IQ8 series in solar micro-grid. When combined with IQ battery backup, it would vastly extend the runtime for an extended outage that includes daylight hours - I have had a few of those over the last 16 years, including one PSPS.
The other option would be to leave the 28 M215 in place, and connect them to the load controller on the Combiner 6c, to turn them off during outages. This would still leave the 42 IQ8+which have higher wattage panels in micro-grid. It would save a lot of labor in installation also - installer not needing to go on the roof.
I see a few options from here.
don't install any batteries now. Forget about the SJCE incentive. Wait until information is available about Enphase V2H to make a decision
install the Combiner 6c with 3 x Battery 10c, ie. 30 kWh of batteries. Leave 28 M215 in place. Configure the IQ8+ for solar micro-grid. Complete this by October 24 to collect the SJCE incentive.
Add the IQ bidirectional charger later on, to provide the additional 85 kWh of battery backup. I need to know now that my car will be compatible with IQ V2H charger to choose this option.
Same as option 2, but convert M215 to IQ8-60. I still need to know now that my car will be compatible with IQ V2H charger to choose this option.
Same as 2, but install 70 kWh of batteries now. Forget about V2H charger compatibility.
Same as 3, but install 70 kWh of batteries now. Forget about V2H charger compatibility.
Explore some non-Enphase home battery backup options, and install them before October 24 to get the SJCE rebate. I have no idea what this would entail technically. I assume that my PV solar would have to be fully disconnected during outages - no possibility of micro-grid. So, it would need to be a very sizable amount of batteries.
TLDR :
a. when will IQ V2H compatibility with Equinox 2025 EV information be available ? I need to know this ASAP to decide whether to add Enphase batteries or not.
b. am I correct that my Enphase solar PV would have to disconnect during outages, if using 3rd party grid battery options ?
c. what are the best non-Enphase battery options that can be used, if leaving the Enphase PV system with 42 x IQ8+ and 28 x M215 in place.
Logged into Enlighten today to find an "In order to maximize your settings, we have set your battery to EXPORT TO GRID. . . ." My settings are always Self-Consumption / Do not Export to Grid. I did go into the battery settings and toggle off Export to Grid. What's up with that?
I believe this may ultimately be a firmware problem, but anyone else unable to connect their EV chargers to the Gateway? Here's what I've tried so far and am still stuck, and I went to some pretty crazy measures...
My home network has a few subnets, so I started by forcing both of them to be on 192.168.5.x. That didn't work. Then I saw the IQ 40 was connected via 2.4 GHz and the Gateway on a 5 GHz channel. Tried to pause 5 GHz to set the Gateway's wifi back up and hit another problem: my wifi password has special characters (# in this case) which the Enphase App disallows. Which is hilarious because the gateway is already connected to my wifi using allegedly disallowed password characters. Tried putting it into AP mode and connect directly to the Gateway's local IP (172.30.1.1) and that no longer works either.
Then I went nuclear.
I decided to hell with all the wifi problems. I ran an ethernet cable from the Gateway, down through a new hole I drilled, through some flex conduit, through my basement soffit, up through the floor and directly to the main managed switch (I have two, it's a large home lab setup).
Still couldn't access the Gateway via IP. Then I plugged the gateway directly into a PC. Nope. Still no Gateway access. But now that it's hard wired into my system, it shouldn't matter, right? Nope. Still won't connect to the IQ 40.
Super frustrated at this point. My expensive charger works basically only in manual mode and not green mode because it's so slow connecting to the back end Enphase cloud, the excess solar isn't registering in a responsive manner at all. I did get green mode to work. Once. One day. That's it.
Enphase, you need to get your software issues worked out.
Anyone have any advice??
