The same with my SolarEdge inverters. Methinks something changed at PVOutput or something changed in the graphing function that they use from Google or wherever.
mspohr… My graphs are showing the same problem, but beginning a month earlier. Go to Live Outputs and search “Gold Country, Auburn CA” to see mine. You might want to join the “Enphase” team (397 sites) and you can see who else has the real-time jaggies.
The issue seems to be on the Enphase side since their Enlighten monitor shows the same issue. PVOutput, through the Enphase “team” shows that it’s only SOME of the Enphase installation that have this problem. And it’s many more recently.
The numbers suggest its not an Envoy failure, but possibly a new firmware update, or a policy change for Enlighten.
Hmmm… wayner9, I see what you mean. Is the SolarEdge site giving you smooth (5 minute data), but PVoutput is not? That is not my situation… Enlighten shows only 15 minute data and feeds it to PVOutput.
I wonder if you had “donor” status and it expired??? A donation gets you 5 minute refreshes, but I thought you still got the 5 minute data, just later. Maybe not?
Mine started the afternoon of the 29th. It’s not a pvoutput thing , I see it in my enlighten as well. I think that Enphase is reducing their server bandwidth by going to a coarser resolution. I’m guessing their stock price may have something to do with it. Need to check their quarterly reports for G&A cost savings.
There has been no changes on the PVOutput side - it reports the data returned by the Enlighten API.
However, it has not affected all Enphase systems. This one is still reporting 5-minute data.
Enphase is still reporting at 5-minute intervals, however they seem to be averaged from 15-minute data.

The MyEnlighten site shows 15 minute intervals for me now on the daily graph for current dates and also the past few months. (I’m not sure what it was showing before since I rarely use it.)
However, I was able to download data for yesterday and it gave me the data in 5 minute intervals so it still seems to be collecting data in 5 minute intervals.
I don’t know what’s happening on the PVOutput side since it’s now showing 15 minute intervals rather than 5 minute intervals. Is Enphase now only handing out 15 minute intervals to PVOutput?
(Edit: Just noticed that Enphase gives me data in 5 minute intervals but they report the same value three times so they must be collecting data only every 15 minutes.)
Enphase does still send “report” power (kW) data in 5min intervals, but mine is not correct, probably computed from stored 15min energy (kWh) data. Here’s my enlighten graph and a sample of the report data from yesterday. Note the strange repeating sequence… 2 equal values then a lower one resulting in a sawtooth graph. Graphs and data before 6/1/17 are smooth 5 min data (except for clouds!) and are all sawtooth after that. But “todays” graph (shown last) is ALWAYS stair-step, and that’s the data PVOutput gets… go figure.
Whoa… I just noticed that the API data shown by bankstownbloke shows the same sawtooth pattern that I showed from the Enphase report data, above, However PVOutput seems to smooth it out into 3 equal power values in a row… yes?
For me everything still looks the same using the SolarEdge monitoring and the SolarEdge app. But in PVOutput I get the stairstep charts as shown by mspohr as my reporting is now only every 15 minutes. Could these be because I have not renewed by PVOutput subscription yet? So now my reporting interval is lengthened to 15 minutes?
I just donated again so hopefully I will be back to normal soon.
I have the same issue from 13 June. https://pvoutput.org/intraday.jsp?id=34446&sid=32620
I have noticed on the PVOutput side that my settings for the system automatically default to 15 minutes even if I choose 5 or 10 minutes once I reoload the settings page it is back to 15 minutes, using a longer setting does save correctly. So it would seem something is different on the PVOutput side.
I also noticed my Enphase system reporting changed on the 30/06/2017 at about 10.30am AEST. It now reports the same value for each 15 min interval rather than a unique value every 5 mins. What has changed??
I checked about 60 systems (of 397) in the PVOutput “Enphase team” today, and about 20% of those had lost the 5 min update in the past month, 2 of them yesterday, and 1 just this afternoon. I’m wondering if it’s aimed at a certain class of site… like those of us who self-installed and aren’t linked to an installer, or those using the API… or maybe it’s just a slow roll-out for some reason.
The change is on the Enphase side.
Each interval downloaded from Enphase is 5-minutes apart.
The power amount reported repeats for 10-minutes (two intervals) as per the below. This results in a ‘staircase’ graph.
- 155W
- 155W
- 104W
- 111W
- 111W
However, this is only affecting some sites.
Please contact Enphase support if your site is affected.

This is the polling interval, which controls how often data is retrieved from Enphase.
The status interval is always 5-minutes for Enphase.
These settings are unrelated to the change made on the Enphase side, which was to average 15-minute data into 5-minute intervals.
Here is a sample of the data I downloaded from the MyEnlighten site after the change.
They say they are reporting 5 minute intervals but the report the same value for three 5 minute intervals in a row.
(I’ll give a try at contacting Enphase but in the past I have found their support to be useless. They just say “contact your installer”.)

I have redonated but I still see data constant for three - 5 minute readings. I have Energy set to disabled, Temperature and Voltage set to enabled.
If any of you have an installer linked site, you might want to see if they understand this monitoring change at enphase.
I’ve sent a 2nd support request on this to Enphase, and they issued a support ticket number. I’ll post here If/when they respond. (My first request was closed after 10 days with the reply: “It appears this issue may have been resolved”… hah!!)
Interestingly for me, the my enlighten data does not have the same repeating values… I get the saw tooth described earlier… shrug…

I won’t be holding my breath for any update from enphase…
Oh and I didn’t self install or anything like that.
Starting today, add me to the list of users experiencing 15 minute data blocks from Enphase. Firmware hasn’t changed (R3.12.49). I log what is sent from the Envoy to Enphase and it shows the same 15 minute blocks now too. Will contact my installer, Metro Solar, and get them to advise what’s going on.
