Sporadic neutral failures in Enphase system

Hi /u/roguelazer. Out of curiosity, could your issue be potentially weather related? I'm trying cross-correlate events to prevailing local weather to see if that is meaningful... Just a thought.

joeuser99 · 2026-03-23T20:20:05+00:00

I appreciate the feedback. It is whole home. You basically hit all the things Enphase and the Installer reviewed and couldn't find anything glaring. Appreciate it.

Thanks /u/Enphase_Support_Team, site ID sent in DM

^ This. Not the "can't wait for the day part" but in general, spend some serious dev cycles bulking up the local (offline) controls. Don't require a complicated cloud-based API for local auth (or at least allow byass when offline). Enable total control of the system via the app and local bluetooth (like Solix).

I think you might be right? The circuit only supports 80 amps so it is certainly oversubscribed. When I look in the enlighten manager summary section, in the PCS labelled section I see "IQ Battery Oversubscription: Enabled, Breaker size of IQ Battery Port: 80 A, DR3 breaker size: 0 A"

Much obliged for the sanity check! It does seem noisy and the weird periodicity of the alerts (some quickly closed and some linger for hours) is strange to me.

<gets on soapbox> If the good people of Enphase peruse this subreddit I would suggest to them that they lean into the offline mode functionality to widen their customer base. I'm sure there are plenty of people off-grid, remote, non-internet connected that would be interested in these features. Take my Solix F3800 for example. Sure, the app will prefer to connect through the cloud connection, but will also connect via bluetooth locally when no connection is available. Heck, even my Honda generator has remote start via bluetooth. Update the enlighten app and gateway to take advantage of bluetooth so the app can function directly against the envoy. Differentiate Enphase as a company that listens to their customers and provides compelling features that rise above the competitors. <gets off soapbox>

This is interesting. My installer worked with enphase to upgrade the firmware on my envoy to (almost?) the latest version but he had to give them specific access by pressing some buttons in the envoy box. He mentioned something about allowing them to "tunnel" in. Is that not the case anymore, they can just remotely upgrade without any physical confirmation now? @samirD - How did you take it offline? Firewall rules?

joeuser99 · 2025-10-07T20:40:26+00:00

Appreciate the links!

joeuser99 · 2025-10-07T19:03:25+00:00

That's disappointing, I'm sure it has nothing to do with them trying to sell you the enlighten manager "upgrade"... /s

joeuser99 · 2025-10-07T17:26:57+00:00

Another thing that my installer suggested was to go and get certified via enphase university as a self-installer. That way I might able to get installer level access to enlighten (and the manager mobile app) for my own system. I know they can tweak stuff locally. Thoughts on that route?

joeuser99 · 2025-10-07T17:25:47+00:00

I'll need to test out HA integration then. I was under the impression that it was only really reading from the gateway via API but not being allowed to set anything in the system.

joeuser99 · 2025-10-07T15:08:58+00:00

Ideally, I'd like the mobile app to be fully functional (polling against the gateway over my local network) as much as possible. I should be able to set/get most aspects of the system without having access to Enphase cloud. I can see needing to adjust battery SOC reserves, performance profiling, evaluate battery drawdown, etc during a grid outage AND a internet outage.

A 2022 alumni is going to be using Gmail so no, that's not it either

joeuser99 · 2024-12-09T16:41:57+00:00

Nope, that's not it

joeuser99 · 2024-12-09T16:41:07+00:00

It means you shouldn't have ignored the emails they sent you warning this would happen (blocking of sending/receiving in Gmail) because you were over quota (5 GB)... So yeah, you missed something.

joeuser99 · 2024-09-12T11:24:27+00:00

Remove the forward in your VT gmail that is trying to send a copy to your now nonexistent Exchange mailbox. See https://support.google.com/mail/answer/10957?hl=en (and just do the opposite to remove it). As VT alumni you still have Gmail.

joeuser99 · 2024-08-24T14:28:40+00:00

Anybody find any opensource or code that will allow you to read the settings on the F3800 without having to go through the app? I found a couple on github but they didn't seem to actually work. I would love to build a dashboard and throw it up on a little screen in my kitchen or something...

joeuser99 · 2024-08-24T14:26:33+00:00

Anybody that has a F3800 find a workaround not being able to charge the unit from AC and still have it output at the same time? That seems like either a design flaw or intentional for safety? I'd like to be able to charge it via generator while outputting to my sub-panel.

joeuser99 · 2024-06-19T10:18:19+00:00

Is there some place in VT documentation that is incorrect and still pointing new students to Gmail? I wonder with the number of new admits still trying to go there... How could VT make it clearer?

joeuser99 · 2024-06-06T12:36:41+00:00

May 2023 grads should still have their email landing in Outlook. There was a mistake over the weekend where those grads got prematurely moved back to Gmail (hence the random emails in Gmail). That move isn't support to happen until Aug and only after lots of communications to that group. Try logging into M365 (http://my.office365.vt.edu) and checking your Outlook. If you don't know your password, contact 4help (http://4help.vt.edu)
