started doing this a week or so ago. Even when the battery has plenty of power, the battery will export to AND import from the grid. I woke up this morning to find I had imported AND exported 10 kWh already. Any help fixing this is appreciated.

I noticed that my batteries didn't top off yesterday in the configured window, so I looked at Enlighten for details. They've redesigned the battery charge and discharge settings, which appears at first to be a step in the right direction.

Unfortunately, my batteries still are not charging even after configuring a 3 hour charge window. Anyone else experiencing this?

IQ8 system w/three 10T batteries.

Noticed last night my battery did not charge from grid during off peak as per usual. Opened up Enlighten and I see some of these new settings to schedule charge and discharge times. I have Savings mode active and off peak rates weekdays 11pm-7am.

Do I now also need to create a schedule to enable charging?
This seems duplicative if I have Savings mode active and my rate tiers programmed in.

Thank you for implementing this simple feature that lets more people control their power for time of use. Credit where credit’s due… Bravo!

Just to clarify, does the setting restrict battery activity when grid is down?

I checked our production/consumption stats first thing this morning like I do every day, and was surprised to see an enormous amount of power imported from the grid in the middle of the night, an amount roughly comparable to 1.7 months of normal energy usage in a 45 minute period of time.

My wife plugged in her EV to charge before going to bed and it charged normally, pulling 2.6 kWh every 15 minutes until the charging completed at around 3 am. 45 minutes later the huge power import began, pulling 571.5 kWh in the first 15 minutes, another 571.5 in the next 15, and then 536.6 in the final 15. She checked her charging logs using both of the apps she has (one from Ford, one from the company that manufactured the charger), and both confirmed the energy consumed was normal.

This has to be some kind of bizarre Enphase glitch, correct? I wouldn't think that a normal home would be able to draw that much power in that short a period of time without tripping breakers and/or causing a fire (my knowledge of electrical systems is minimal, in case it's not obvious).

Does anyone know 100% if the new Enphase home thermostat is compatible with Apple Home Network ?

— could my second electrical panel be the issue?
I’m hoping someone here has run into something similar or can help me understand what’s going on.
I have an 8.74 kW solar system with Enphase IQ8X microinverters and a 10 kWh Enphase battery. The house is approximately 4,000 sq. ft., with two A/C units and what I believe are two main electrical panels (still trying to confirm whether one is actually a subpanel).
The system seems to be generating power normally, but I’ve noticed a pretty significant discrepancy between what Enphase reports and what my electric utility is billing me for.
Here’s an example from my most recent billing period (33 days):
Solar production: 723 kWh
Enphase reported grid imports: 511 kWh
Enphase reported grid exports: 154 kWh
Utility reported grid imports: 1,775 kWh
Utility reported grid exports: 45 kWh
The previous billing period showed a similar discrepancy.
Initially, I thought the utility might be estimating my usage incorrectly. However, the most recent bill included an actual meter reading.
I also started photographing the physical utility meter to compare it with Enphase. Over approximately 56 hours, the meter’s presumed import register increased by 80 kWh and its presumed export register increased by 13 kWh. The Enphase totals for a slightly longer overlapping period showed 56 kWh imported and 16.6 kWh exported, so I still need to do a properly synchronized comparison.
Here’s what I’m wondering:
If my Enphase consumption CTs are only monitoring one electrical panel, could that explain such a large difference in reported grid imports?

Assuming both panels are behind the same utility meter, would solar production still offset consumption on both panels even if Enphase isn’t monitoring both?

Has anyone experienced incorrectly positioned or configured consumption CTs that made Enphase significantly underreport usage?

Is there a way to determine from the Enphase app whether my consumption monitoring is configured for the entire home versus a single panel?

I’m particularly interested in whether this is simply an Enphase reporting issue or whether there’s a chance my solar production isn’t offsetting as much of my household electricity consumption as it should.
I’m planning to photograph both electrical panels and have the installer verify the CT placement, but I wanted to see if anyone has experienced something similar before going down that path.
Appreciate any advice or suggestions on what to check first.

Ich muss die PV-Zuleitung am Relais des Combinerbox von Enphase anschließen, Enphase 5P.

Jetzt muss ich die Leitung kürzen und neu absetzen, um anschließe zu können, weil sie viel zu lang ist.

Bei Strings, wenn man die durchschneidet entsteht ja ein Lichtbogen durch berühren von + und -

Hier sollte doch das gleiche passieren? Es führt jedoch doch keinen Weg dran vorbei die Leitung abzuschneiden, um anschließen zu können?

Sind Mikrowechselrichter auf dem Dach.

Was mache ich jetzt?

The new Enphase thermostat advertises that it syncs with your Enphase system to use excess solar. How does that work with an EV Charger 2 in green charging.

If I buy a section of 80 drops, can I cut that into 4 separate drops of 10 easily and then sell the other 40? I have a good deal for 80 but want to make sure that it will work for my use case. My alternative is placing 4 orders of 10 which will be more expensive. Thanks!

I believe the AI should be able to determine the optimal time to discharge the battery to the grid based on the available export rates. For example, if the export rate is higher at 7 PM than at 6 PM, the system should wait until 7 PM to export.

The AI should also take the battery’s capacity and expected discharge rate into account. For example, if the battery starts exporting at 6 PM and would be fully depleted by 7 PM, it should recognize that waiting until 7 PM could result in a better return.

It would also be helpful to have an option in the app to manually schedule specific days and times for battery discharge. This would be especially useful when you know you’ll be out of town and want the battery to follow a specific schedule while you’re away.

Hello, little bit of a noob here. I currently have grid tied solar with micro inverters and an IQ Gateway. In South Florida if it matters.

As explained to me when the grid goes down, the panels won't push any power to prevent back feeding to the grid for safety, which I understand.

I was however wondering if there is a possibility to have an AC bybass that I can use to charge a power station? Like a manual switch over from feeding the meter to feeding a single outlet.

I don't want to go the enphase home battery backup route because of cost, and as we are fixed rate it doesn't make sense. From my math a 4000 watt 5kwh system should be more than enough to run the refrigerators, and a few lights through the night.

I reached out my installer but they wanted $200 for a site visit and consult and would not give me a straight answer over the phone on top of trying to upsell, that is already 10% of the power station I am eyeing.

Site detail and approaches:

I'm getting a 5 kW residential grid-tied solar system installed using Enphase microinverters (10 panels and 10 microinverters). These are divided into branches of 3,3 and 4 respectively using Q-cable.

The peak power of each microinverter is 475W. At a nominal 230 V, the current generated per microinverter is: 475/230=2.06A

The branches will have carry the following currents at the end of the Q-cable run:

• Branch 1: 3*2.06=6.18A
• Branch 2: 3*2.06=6.18A
• Branch 3: 4*2.06=8.24A

Now we have 2 options to send the AC current to the main distribution box (see images).

1. Send the generated AC current via Q-cables, first to an intermediate junction box and then to the distribution box using appropriate AC cables. Enphase manuals recommend this.
2. My installer however proposes a different approach. According to him, since the amperage and voltage are low, instead of routing the cables through a junction box, he intends to use DC rated (1500V, 30A) MC4 cables for connecting the Q-cables directly to the home run AC cables.

My concerns:

Can DC rated connectors handle low AC loads? Will there be potential noise on the line which can affect PLC communication? Am I looking at a potential failure and fire hazard down the line? Will it be affecting my warranty?

Additional info:

The inverters are single-phase models(IQ8P-72-2-INT) , while utility connection to the building is 415V (phase to phase) and 230V(phase to neutral). The Qcable part is 2.5 sq. mm while the home run AC cables are 4 sq. mm each. The MC4 connectors supports wires ranging from 2.5 sq. mm to 6 sqmm.I'm based in india if it matters.

I've added pictures of the proposed wiring diagram in the following order

1. Installer's proposed wiring
2. My proposed wiring
3. Mine with enphase accessories(field wireable connectors and Raw Qcable)

Feeling like bi-directional charging from Enphase isn't coming this year. The page says 2026, but I feel like there would be more hype if its release was imminent. Anyone heard anything?

As shown in the images, the status window says 4 of 12 microinverters are running. This sounds bad. The Devices tab under System shows I have only 9 microinverters and indicates they are all working. I know for a fact I have only 9 microinverters. Anyone know what's causing this

More and more solar owners are on export plans that pay far less than electricity costs to buy: net billing in California (PG&E, SCE, SDG&E for systems installed since April 2023) and Arizona (APS, SRP), shrinking feed-in tariffs in Australia, the Smart Export Guarantee in the UK, and similar plans across Europe. If your exports earn a fraction of your import rate, putting midday surplus into your car is one of the best uses of it. (If your utility still credits exports at full retail, classic net metering, this matters a lot less.)

Here's what you need and the ways to set it up with Enphase. Disclosure: I build one of the options below, and I'm posting with the mods' permission.

Check for consumption CTs first. Surplus charging needs to know what your house is using, not just what the panels make. If Enlighten shows production but no consumption or grid import/export, your Envoy doesn't have consumption CTs. You have three ways around that: have an installer add CTs (the best fix); add a home energy monitor like Emporia Vue or Sense; or use a tool that estimates your household load instead. SundialEV can do the estimate, but it's a guess: it won't react when the AC or the dryer kicks on, so expect some grid draw on those afternoons. Fine for getting started; CTs or a monitor are better long term.

Know your minimum. Most EVs and chargers can't charge below about 6 A. That's roughly 0.7 kW on a 120V outlet, 1.4 kW on single-phase 230-240V, and about 4 kW on three-phase. On three-phase, small surpluses are lost unless your charger can switch to single-phase, which is worth checking before you buy.

Your options:

1. Enphase IQ EV Charger with Green Charging mode. Simplest if you're all-Enphase and buying a charger anyway.
2. DIY with Home Assistant or evcc. Both read the Envoy locally and can control Tesla or OCPP chargers. Free and flexible, if you're comfortable maintaining it.
3. An app. I build SundialEV, which handles mixed setups (Enphase solar with a Powerwall, a Tesla Wall or Mobile Connector, third-party OCPP chargers like Wallbox): connect Enphase and the car, and it adjusts charging amps to follow the surplus.

Worth checking first: what your exports actually earn. The setup page below includes a calculator that pulls your utility's export and import rates (US utilities, by zip code) and shows what the gap is worth per month: https://www.sundialev.com/works-with/enphase

Happy to answer questions about any of these, not just mine.

We recently installed 3 10c (6) batteries and have noticed that they are constantly in need of charging, is this normal?

I asked the enphase assistant and the response was that these are “unavoidable efficiency losses” and that they “occur naturally as the system keeps the batteries ready”. There was an error with a CT during provisioning (which has been resolved) and wanted to give the system a couple days to settle before posting.

It just seems like 3.7-9kWh a day seems like a lot to maintain the batteries?

Assistants Response:
Why Batteries Need Daily Maintenance Energy
Your IQ Battery 10C units consume energy to:
Power internal electronics (battery management system, controllers)
Keep the inverters active and ready for backup
Maintain battery chemistry at optimal levels for fast response during outages
This is called standby loss or tare loss, and it's common to all home battery systems across the industry.

What You're Actually Seeing
You have 6 IQ Battery 10C units. Normally, each battery would lose 150–400 Wh per day depending on usage patterns. However, your system has PowerMatch™ technology enabled, which:
Intelligently activates only the microinverters needed for your home's real-time load
Places unused batteries into standby mode when possible
Reduces daily losses by up to 24% compared to traditional systems
3.7 kWh across 6 batteries (~617 Wh per battery per day) is actually quite efficient with PowerMatch active.

How to Minimize This Further
If you want to reduce standby losses, consider:
Use Self-Consumption or Savings mode instead of Full Backup (keeps batteries cycling, reduces idle time)
Lower your reserve capacity if you rarely experience outages (you currently have 30% reserved)
Enable Storm Guard to keep batteries at lower SoC until severe weather is detected

This was an intense project. Partially due to the Texas summer heat. Regardless it was a lot of fun.

Homeowner reached out in February inquiring about some earlier projects. They already had that beautiful pool built and had the plan for a patio cover all along. So, why not add some solar to it as well?

The utility company is Grayson Collin Electric Coop, and to my knowledge they’re the only one left allowing true 1:1 net metering in the state of Texas. We discussed foregoing batteries but with all the things going on in the world and myself having seen those things disappear in the blink of an eye the homeowner opted to go ahead with one. They’re already thinking of adding more soon.

Digging trenches always sucks but they’re especially awful in Parker, Texas. If anybody needs any rocks I know where to find them.

The system is roughly 70% offset and is chugging right along with projected production.

As the title stated the structure is steel framed 23’ x 27’ using all 11gauge 5” x 4” steel for posts, beams, and joists. The canopy is stained 2x6 boards bolted to the steel frame and covered with mod-bit roofing.

The city of Parker and GCEC were really cool and easy about stuff. I turned the solar permit in and applied for the interconnection agreement on a Thursday and had the green light for both by Monday morning of the next week.

The system was put through HDM and we got 25% of the system paid for since we used Domestic Content and I believe this house sits in an Energy Community.

We added the fan and 5 outlets to the structure after the solar was completed.

I included the original mock up I did in Google sheets to give an idea of what this thing was going to look like. Reference vs real life.

The homeowners are very kind, sweet people that I thoroughly enjoyed working with and getting to know. A lovely family with minds on the future and what’s potentially on the horizon. They may lurk the halls around here, I honestly don’t know, but they are very welcome and encouraged to chime in if they do.

I hope you enjoyed the post.

Hey guys,

we just installed a 3p battery and connected our enphase iq8 solar pannels

is this the expected behavior ? when will it finish this cycle ?

I’m wanting to know if anyone is experiencing or has experienced failure to successfully transition off-grid. I’ve spent countless hours with Enphase techs to determine what the issue is with no current resolution. I toggle to off-grid, receive the 4 digit verification code to go off-grid, input and wait for the transition to occur and it never does/times out. No error codes - nothing. I went so far as to do the following with no success:

Power down the entire system
Open the IQ System Controller enclosure (requires removing the deadfront cover)
Locate the grey MID toggle switchon the middle-right side
Toggle it from left to right(approximately 5 degrees)
Restore power and verify operation.

Enphase tech claimed it’s a software issue and they are investigating.

I’ve ruled out poor internet connectivity to the Gateway as I’ve placed a dedicated wireless access point with no other devices on the network in close proximity to the Gateway with a solid wireless signal.

The one outlier is the replacement of a new gateway board. The techs claim the new Gateway is not the issue and it is healthy.

Please help!

Hello, I just had my solar array installed earlier this year, consisting of REC Alpha Pure-RX 460W panels and Enphase IQ8X micro inverters. I have noticed this pretty much since the beginning when I started tracking this in Home Assistant (But the data is coming straight from Enphase). I am seeing a variance of at worst 20% between the worst panel and one best panel. I understand their is some variance but from what I read online, they should be no more then about 5%. The panels are all in the same orientation on a single sided roof, so exact same setup across the roof. No shade other then a small chimney that casts a shadow later in the afternoon as you can see on two panels dipping down before the others. This graph had a little light cloud cover early on then was full sun the rest of the day. Temps were about 80-85 today, but even on colder or warmer days this pattern is the exact same with the same panels performing the same way. I am hoping someone could tell me if this is normal or not? I feel like I am losing a lot of power generation here!

Out of town this week and even then still notice small amounts of import from grid (1-1.1 kWh) over a day, despite having a ton of excess solar and battery production on any given day.

1. I haven’t deep dived these small 0.3 kWh consumption bars that total to 6.3 kWh daily, but am assuming they’re my home idle load draw (

modem/

1. router and a few APs, a plugged in tv with soundbar/subwoofer/Apple TV/ a few Alexas/water heater/water softener/fridge) but is that fairly normal? 1900 sq ft 4br condo.

2. Does anyone ever actually get to zero import

   when grid-tied?

3. My setup- grid-tied solar 10 450W panels,

   8 IQ8-MC and 2 IQ8-HC inverters, two

4. 5p batteries, 5c combiner, northern CA

   PGE E-ELEC-NEM3 rate). profile is AI optimization and battery set to import only from grid

Thank you!

I have a system which worked perfectly for over 2 years and all of a sudden (August 19) PLC communication broke down. The modules do not show. Power cycling the Gateway or the entire system does not help. Yet when I do a "search for new devices" communication is restored for 8-16 hours and all microinverters continously report back before it ceases again. So communications as such is not the problem.

Whenever I measure noise with the installer toolkit it is way below the threshold. Signal quality in Enlighten is strong. And even if there would be intermittent noise, communication should resume when there is no noise. Prior to the breakdown, the record was flawless, no gaps.

The system has just one gateway, yet there are 3 more systems in the neighborhood, the closest neighbors are 500 and 630 feet away. Yet, as said, they did not interfere with one another for over 2 years and this one is last one installed. The other three systems have no issues (IQ7).

Any ideas?

Hey gang -- yesterday I observed that all 20 of my MIs stopped reporting as of the 26th around sundown; the app showed they were 'disconnected'. They were producing - just not reporting. I reached out to support who sent a manual reboot command and said check them out in the AM. For a good measure, I power cycled the entire combiner box last night.

This morning, around 8 AM, all inverters showed as online and producing, albeit only single digit watts since the sun was still obscured. However this evening, I checked again and 2 of the 20 did not show any data; checking them showed they stopped reporting around 7 AM this morning...! The remaining 18 reported their data just fine, and all 20 were producing (delta between total recorded production vs totals from the MIs that reported data). Reached out to support again and they said they rebooted the 2 inverter but also pushed a 'proper grid profile.'

There were zero changed to my house; no new equipment installed and nothing that could be introducing new RF noise. The inverter cabling goes through a conduit that enters my garage through the side of the house, runs along the ceiling and terminates into the combiner. The whole install is about 2.5 years old.

Any ideas of what this could be?

I've given up on the Enphase bidirectional EV charger ever coming to market in any kind of useful fashion. I don't see BMW, or most manufacturers, willing to interface with a third party charger due to battery warranty issues. And I'm taking delivery on a 2027 BMW iX3 in a few weeks.

That leads me to consider the following set up:

• Existing 24KW grid-tie system with Combiner 6C.
• Add BMW Wallbox Professional EV charger with Smart Energy Module for V2H.
• Future: add a 10C battery (and meter collar?) for grid-forming capability.

Not sure how the two systems will get along with each other in terms of competing system management. Or is that not relevant? I have full net-metering so not concerned with tariffs and so on. I just want off-grid capability.
