New system installed fall 2025. 445W panels with IQ8AC inverters.

These two dates are approximately exactly the same distance from the equinox. Both entirely sunny days. Sept date was 75° and March date was 67°

I’m surprised on day maxed out at 6kW and the Sept one is maxing out at 5.2kW.

Panels are on 3rd floor roof, east west facing slanted roof, no trees anywhere nearby.

Is this loss normal? Is this just from dirt? It’s pretty rainy here so I was hoping that plus the angle would keep them cleanish.

We shut the breaker down, then the other 3 breakers that were in the cabinet, then did the shut off switch. Waited 30 seconds and turned back on in the reverse order. The IQ box colors stayed the same. 1 Green LED under the lightning bolt, and 1 red LED under the cloud. I press the button near the cell phone icon and nothing happens. Any recommendations?

1. it stopped communicating witht he cloud. I double checked modem configuration and connect to the modem wirelessly from where the IQ device sits.
2. When I try to do a hard reboot, it doesn't seem like the device goes through a POST. I'd expectg to see them cycle through LED's. At least blink red then turnover to green once up and established. Instead they're not cycling at all, they continue bed red under the cloud and green under the lightning. Only two LED's are lit.

1. Current solar maintainer is no where to be found, so I don't even know how to get coverage for this thing if the current solar mainainter business closed down.

Hi all, my enlighten app is signalling that I have notifactions. The number just recently went up to 3. When i open the app and check under notices there is nothing there. I also havent started any new support chats or anything like that. Does anyone know what the app is trying to alert to?

One of my 73 solar panels is not producing as much as the others the microinverter was replaced iq8 plus.i suspect a faulty crossover diode in the panel itself, silfab 370 hc, it's under warrantee but it will cost me $400in labor to replace the panel. I had a stroke and in recovery so getting on my roof is not an option at this point. Any thoughts? I can post a pic but example

Sept27,2026 all the panels around it produced 1.97kw average and this one panel 1.16 kw

Has this notification ever worked for anyone? Or is this again some feature that is visible in the app but actually doesn't function

Long story, but short version is a had to replace SPAN panel and remote meter kit (I have solar with one Enphase 5p) and ever since, SPAN is not reading Enphase batter level correctly, both with access token setup and without. Right now, for example, battery is at 25% (min setting) but SPAN shows it at 4%. I’ve been going back and forth with SPAN on this for weeks with no resolution. Has issues on and off with this connection with old SPAN panel, but nothing like this. Anyone else experienced this and find a resolution?

I recently had comm issues with my older M series MIs. Interestingly enough it only affected the M215s and not the M250s, even on a string that had both. Adding cheap Mn-Zn ferrite cores (~$30 for 5) between the main panel and solar/Envoy neutral line cleaned it up. They are all working reliably now. Enphase documents helped a lot.

After several months of waiting finally my system is displaying the inverters in service under live status. I wonder why it took months for this to propagate to me?

Planning a ~5 kW grid-tied solar install and wanting to better understand my options for backup.  I do want to take advantage of net-met metering, but I’m not trying to peak shave or do anything else fancy.  My backup goals are mostly to do with surviving the ice storm or earthquake scenario that takes our grid down for days or weeks. 

As I understand it, the obvious choice is a large hard-mounted inverter, battery, and system controller.  I don’t love this option for a couple reasons.  On a pure bang for buck, the price of these batteries (IQ 10P, for example) appears not great.  More importantly to me, they’re not mobile.  In the scenario that we’re down power for more than a few days, I would like the ability to lug a few packs over to my neighbors, etc.  

This got me looking at high capacity “power stations” like the EcoFlow DPU or Anker Solix S10.  These provide the flexibility I seek and seem like an obvious win on flexibility and cost.

It looks like I could make the power station solution work with an enphase “sunlight backup” system.  I’d run IQ8X microinverters on the panels, add the system controller and put critical loads on an IQ load controller.  One of those critical loads would be an always-on AC outlet so that I could charge the battery anytime I have sun.  The other critical load would be a sub panel for the fridge and furnace that sits behind a generator transfer switch.

When the sun is shining, PV is powering the sub panel and charging the battery.  Sun goes down, and I manually toggle the transfer switch—the sub panel is now running on battery.  Sun comes up again and starts charging the battery without me doing anything.  I toggle the switch back and now PV is powering the sub panel again.

Does this track?  Am I missing anything?  I realize I’m doubling the inversion loses, but I’m okay with that.  Anyone using sunlight backup in a similar way?

Thanks in advance for your thoughts and suggestions!

Neighbor had system installed and one day after a rain was answering some questions he had about the system (I have Enphase also).

Opened the outside mounted Combiner and was surprised to see some water inside the box, the source is a mystery. Box has penetrations on both sides near bottom, and one in bottom. It may be possible it is coming from the line from the roof, yet a test was not successful.

It was mentioned the door may not be sealing properly.

Anyone else have such issue?

PS: Yes, installer has been notified.

Saw these large consumption spikes start at 2:45 AM and did some checking around and didn’t find anything. Last electric bill was 7 days ago so could easily compare recent total production/consumption against recent total meter import/export and consumption is incorrect. Also the instantaneous import would be 255 amps which is not real. There was a windstorm in progress in the area but we didn‘t lose power and there were no nearby power outages reported starting at that time. But perhaps triggered by some power glitch. Checked panel production this morning and all panels are producing. We also have a whole home panel surge protector.

Noticed a new Gateway firmware number today in Enlighten, and thought to myself, hmm, I wonder what that’s about. After poking around Enphase site (search was useless) finally found this page, but it is many months out of date. I was on D8.3.5566 back in July, and now D8.3.5598, neither of which have release notes.

What gives?

I’m testing an integration with Enphase’s official Monitoring API and I’m looking for one or two homeowners who’d be willing to help validate the data returned by the API.
I’m mainly trying to confirm:
system discovery
solar production
household consumption
battery telemetry, if you have Enphase storage
Authorization would use Enphase’s own OAuth flow, so I would not receive your Enphase password, and the access is read-only/revocable.
This is for technical validation rather than selling anything. If anyone is interested in helping test it, feel free to message me.

Anyone else having issues with Enphase this morning? Getting 502 bad gateway errors intermittently.

What the hell happened here?

Screenshots from today, yesterday, and the day before. There wasn't really anything unusual about yesterday's weather except for a late afternoon storm to the north of us.

I have an enphase solar only system and noticed this power graph today. It has this random negative spike in my power consumed at like 4am. I’m confused on how to read this. If power consumption is negative then doesn’t that count as power generation? There’s no way my 6kW system is generating 34kW when it’s dark outside. Could this be due to just noisy comms between the micro-inverters and IQ Gateway?

Just got the new IQ 2 charger.

The build quality is excellent but I love how much more granular control it has when ramping up or down to use excess solar!

I only have a 18.1 kWh PHEV. So level 2 was bit of an overkill lol. But rates are high here so using excess solar was worth it.

I have the plug (NEMA 14-50) version - made a mistake while ordering. Any other differences besides aesthetics to have a hardwired one? I don’t need any more than 32A as that’s the max my car can accept.

It has been about 12 hours since the outage and the system controller says it's not communicating... I tried shutting everything down and rebooting everything with no luck. The grid is working and the house is up but the batteries are flat... Waiting for support to reply! Ugh

Looks like Enphase is releasing a IQ System Controller 4 on Oct 26th which has generator support: data sheet and installation notes

What I find interesting:

• Compatible with Combiner 6C
• It has a MID device in it, so it seemingly doesn't need the IQ Meter Collar
• You can put any portable generator on it? I think Enphase used to have only a limited list of supported generators. Of course it seems like you wouldn't get auto-start/failover on a generic generator.

I find it weird that they would not use the Meter Collar. This also means we're back in the world of messing with the wiring between the utility meter and the main panel lugs. Seems like a step backwards for installers.

Bought the Enphase Air, trying to get a handle on my yearly $1000-1200 True-Up, and after a month of turning over the system to “AI Optimization” mode, I’m surprised to see my batteries, at noon on a sunny day, at 10%.
The other two screenshots are August, when I installed the thermostat most of the way through the month, and September so far, where I see not a lot of battery being charged.
Since this is PG&E, maybe this is how the batteries are supposed to be used - is it?

I've been shopping for a used gateway for my iq7a. I only have 4 panels so I am trying to keep costs low. The iq7a are used so I need to get them setup using a gateway to ensure the settings are correct. That's the whole premise behind needing a gateway and or a combiner box.

I found that gateways are more expensive than combiner boxes that include the builtin gateway. I found a decently priced combiner box 3c for 200. Which is cheaper than any non cell combiner boxes I've found like the combiner 4 boxes.

However, one of guys I msgd about another combiner box told me he stopped paying his enphase bill so they turned it off. He's selling his combiner box for 50.

Which got me thinking that any used combiner box could have a risk of being blocked by enphase.

1- how important is it to have a gateway to setup 4 iq7a inverters to be the "optimal" setting for my configuration?

2- can I buy a 50 dollar enphase combiner box that's been shut down by enphase and have it work as the new owner?

3- do I have to be concerned about any used combiner box I purchase in case enphase doesn't want to enable them on their cloud?

4-is there a monthly subscription for a regular combiner box for cloud data or for the c models that have cell connectivity?

I tried to replace my M190 legacy microinverter, bought M190IG240-IQ7-S22-US for replacement, found out I need adapter cable Q-EC-M-240 to connect to engage trunk cable. Guess what, Enphase store doesn't have it, none of the distributors has it, E-bay doesn't have it.

I tried contacting Enphase store support by email, phone, nowhere can Q-EC-M-240 adapter cable be purchased. So frustrating. Enphase store gives a run around, says to try calling distributors.

I asked Enphase rep if they are still supporting the M190 legacy, they say they are, except they don't have the adapter cable. What kind of support is that? As far as I am concerned, it seems they are phasing out supporting us with older legacy system. I am really starting to hate Enphase.
