Hi all,

I capture the data out of our envoy and use it for various automations / graphs etc. Today i noticed the reported voltage reading was over 265V instead of the usual 230v - 245v (australia).

Looking back through the data, it was 246v at 00:07:15 on the 15th may, then was offline, then came back at 00:40:45 (aest) at 263v and has been approx 20V higher since.

We have other devices that capture voltage and they're still the same and not reporting any increases.. its just the envoy.

Just wondering if anyone has noticed similar?

If I had a situation on a large install where the amperage was high enough that back feeding the MSP was not practical and I had a line side tap, then I wanted to add batteries, how would I go about setting up a Microgrid Interconnect Device (MID) and a neutral forming transformer if the amperage limits of a system controller or Combiner 6/meter collar are not high enough? Are there other items on the market with higher amperage ratings that could serve these functions? I'm talking about 125-130 amps of PV AC (86 micros).

Aloha Everyone, I'm new to the group and wanted to know if you can assist me with my panels integration and monitoring. I have 25 Sunpower 327 Watt panels matched with Emphase (Sunpower) labeled IQ7-SX micro inverters. I was wondering if the Envoy ENV-IQ-AM1-240 M is able to monitor the production of the panels. As I understand the Envoy is not compatible with the Sunpower inverters as they (Sunpower) wrote the firmware for the Emphase inverters. Does anyone know if it is possible to monitor production of the panels at all with the Envoy or if there is a firmware update that will allow me to do so? Any help will be greatly appreciated.

Today we had grid outage for about an hour, really the first time (when I could look into it) during a brilliantly sunny day since commissioning our 3rd generation system about 18 months ago. SC3G, IQ8+ producing about 8kW when the grid went out, and four 5P batteries fully charged. We have Savings mode on and this happened as peak rate was just starting at 4pm. So now the weirdness: the solar stopped feeding anything, zero output but the devices were all healthy, and all house load was fed by battery discharge. I called Enphase support and I got basically a reset command sent to the gateway. Nothing resolved because by the time all that happened an hour had gone by and the grid came back. Was really just a "control-alt-delete" response anyway I think. My suspicion is it's a fundamental issue with Savings mode which might ever so simply say that all loads must come from batteries during peak hours regardless of on/off grid and even if it means completely shutting off abundant solar to loads. Is solar simply for export only until the batteries are exhausted down to the limit during peak hours for Savings mode even during grid outage and solar is being completely wasted? Not going to get that answer from support. Anyone have any experience with this?

I had a system installed in 2016 with M250 microinverters and an Envoy-S monitoring system. In 2024, the Envoy S started doing the 4-amber blinking light thing and support said was dead and out of warranty. I bought another Envoy S from eBay, got support to transfer it to my account, provisioned it onto my system with Toolkit, and had data again for my panels. Then sometime end of January 2026, it just stopped working - this time, different symptoms but support basically concluded that it was a defect with the hardware and because it wasn't sold to me initially it wasn't under warranty.

So, what should I do here? The envoy-S seems like really old tech (10+ years) and paying another ~$700 for another one seem like a waste. Any suggestions (aside from 'just don't have monitoring'?)

Enphase held their annual shareholders' meeting this week. They updated the slide on the BIDI DC charger from "Coming in second half of 2026" (in their April investor presentation) to "Expect to ship in Q4'26 for customers in the U.S." in this May presentation. Seems like horizon is getting close to happening. Two other critical questions remain for me: 1) what auto companies will issue certification to Enphase on what vehicles to use this thing (with anything my wife is willing to drive), and 2) whether they will maintain their previous support for compatibility with Gen3 system controllers. On the auto question, I hope they maintain a clear list and roadmap as they do for generators, and don't leave us trying to navigate that. Showing some cars in a video is not enough. If they check these boxes, I am really anxious to move forward!

I've called this problem in at least once, and it doesn't seem to be resolved in spite of the numerous calibrations performed remotely by Technical Support. I've got a Gen 4 system with 2 10 kwh batteries installed in December. I have my battery reserve set at 27% and the battery shutoff set at 7% to allow for the system to restart. So far, no major power outages, but on RARE consecutive overcast days the solar production is barely 10 Kwh per day, ergo there's an obvious battery drain overnight. At least twice now the battery level has been at 23 to 24%. I'm only concerned about this if there is a prolonged evening outage and the battery would continue to drain past the levels I've set. Anyone else encountering this? Other than this, my system is delivering as expected.

Anyone recently install the Enphase Microinverters? I have a String Inverter System and want to get the microinverters. I already have the Enphase Monitoring system. I have 28 panels so 28 Microinverters are needed. Has anyone done this upgrade? How much did it cost you total?

My new 9kW grid-tied system with IQ8HC inverters and an IQ Combiner 5 is being finished next week. I opted not to get battery backup yet due to budget, and to avoid installing Enphase's expensive batteries from my one-brand installer company.

I'm hoping to be ready to add batteries before the end of the year and am researching my options. From what I can tell from my reading here and elsewhere, the current best practice would be an EG4 Gridboss combined with a 12kPV all-in-one hybrid inverter, with the solar panels connected via AC coupling over the generator input.

Does that sound about right? Is there a better route? Installer has said the IQ Combiner 6 (not available here yet) will do a lot of what I need, but I get the impression it's not as simple as connecting off-brand batteries to the 6's battery input and would probably need AC coupling regardless.

Any advice r/enphase?

I’m told by my installer/maintainer that enphase has identified a software update bug from 6/12 that is also affecting others in my area. He says enphase has escalated the issue, but I haven’t heard anything from them. My batteries are at 0% and won’t charge from the panels or the grid. Everyday is money down the drain

I recently installed the IQ EV 2 for my Ioniq 5 and I’m loving it. I especially love how it can throttle power based on my excess solar energy production.

But when I was setting it up, I could’ve sworn I was allowed to pick max amps, and now I can’t find that. Is there a way to adjust this on the fly? It’s currently at 48A and I’d like to lower it in certain situations.

For context, I’ve heard that the ICCU failures on the Ioniq 5 could possibly be due to high amperage AC charging. I know they’re all just theories, but I would like the ability to charge at slower speeds if I don’t need to charge quickly.

Does anyone have recent experience w/ ownership transfers submitted online? I submitted one w/ payment over a week ago and sent a follow-up message earlier this week but have yet to hear anything. Trying to gauge whether I should be more patient or need to find time to call and check in.

I have an 89 panel array that I had installed 3 years ago. This past December, I had 2 10C batteries installed. Since then I've had a gateway meter measurement error and am showing a discrepancy of 25-70% between my Enphase array reports (they split my array into two and have the batteries connected to one side).

Both the solar panel team and the battery team haven't been able to figure out what is happening. Anyone have any thoughts?

First mentioned in last year's investor report. It is nice to have a larger option, but it feels like without larger MID/Meter Collar it will provide much less value.

I received an email from Enphase about discounted pricing for adding an additional battery to our existing system (IQ8, 33 panels and a 10T battery in Northern VA). It said to call for information on the discounts, they in turn directed me to speak with an installer. My original installer (ADT Solar) is out of business (they were awful so honestly a good thing), so they referred me to a new company (Solar SME).

Speaking with them, I told them I'm not looking to make any changes to my electrical panel, I just want extra storage for coverage during outages and bad weather, I was originally hoping to add something smaller then the 10T, but they told me I can only add another 10T to the system.

I was looking to pay for this out of pocket, no financing and conveniently the cost he quoted me is exactly what I said the top of my limit was, $15k. They offered a $1k discount if we do pay entirely in cash.

There was a lot about the call that felt off, but the biggest red flag was that rather than show me an itemized invoice or quote to review he immediately launched into financing and leasing options. Specifically there was a hard sell for the leasing option.

I did finally get him to give me an itemized estimate via email but the pricing seems extremely high. On the Enphase website a 10T battery is $5,097, and my understanding is there isn't any additional hardware needed to add the battery to my existing system, but he is quoting $8,200 here for the battery.

I think he just asked ChatGPT to give him an itemized quote that added up to $15k. I ran it through myself and got a nearly similar answer.

I'm just looking for a gut check that this quote is insane and predatory.

1. Additional Enphase battery unit (hardware + backup capability): $8,200
2. Balance of Material (BOS.): $1,150
3. Electrical labor & installation: $2,100
4. System commissioning & reconfiguration: $850
5. Permit & interconnection handling: $750
6. Project management & logistics: $650
7. Warranty support & service reserve: $550
8. Contractor overhead & operating costs: $750
9. Total Project Cost: $15,000

I've seen others here discuss going through the process in Enphase University to become a self installer, and I think I'm going to go that route now.

Update: I told them to kick rocks and called out the excessive cost increase and the BS line items and they are now claiming it was for a 10C, not the 10T which is not what they told me on the call. And as far as I can tell you can't mix those in the same system. So bullet dodged.
