    I have both temperatures enabled. There is an option to push the Wunderground temperature to an extended value instead of the standard location (as well as solar radiation). You can then plot ambient temperature on the extended graph. I also added a formula because it comes in Celsius and I want it in Fahrenheit.
    Nice, I didn't know they made that change!

    If you auto-upload from Wunderground, yes, PVOutput's temperature field shows ambient temperature. If you choose not to link to Wunderground, but instead enable temperature data from the inverter in the SolarEdge auto-uploader, it is a temperature reading from inside the inverter itself. Unfortunately, I don't think temperature from both sources is supported, which is why I create two systems on Pvoutput for the same installation. One of them will display ambient temp (rooftop temp form my Davis weather station, when installed), while the other displays inverter temp.

    Whatever temperature it is, the inverter internal temp. without aux. forced circulation will probably be something like 25 or so deg C above the immediately surrounding ambient air.

    Array cell temp. is usually above air temp. primarily as f(P.O.A irradiance, wind vector, a few other things). Under bright cloudless skies and a moderate wind and near normal incidence angles, cell temps will run very approx. 25 to 30 C above the amb. air temp. around the array. A dark colored roof will raise the air temp. a few to maybe 5 deg. C above the ground level amb. air temp.

    If you donate to pvoutput you can get 5 minute data and pull other data like inverter temperature.

    Yeah, that's why many of us just upload to pvoutput which does display it. And yes it is logged at 5 minute intervals

    I can confirm this on my system as well. My installer did the GSM kit but I was unhappy with the resolution, so I ran an Ethernet cable this past weekend (June 17). All my data up thru the 17th is at 15 minute rez. Starting on the 18th I'm at 5 minute (I plugged in the cable after the sun was down on the 17th to not interrupt production). Unfortunately there's no caching of info in the inverter apparently to be able to pull a day or two earlier than that retroactively.

    It's also worth noting that after inverter startup, it will report at 5 minute intervals for about the first hour it seems (I had to restart mine because of an isue and got about an hour of 5 minute data while still on GSM). Note that this doesn't appear to be the case after waking up from night mode
    ​​​​​​For what it is worth, the inverter may not cache messages successfully sent, but it does buffer. If you lose your internet connection entirely, it will store a couple weeks (+/- depending on number of optimizers, etc) of data, and push it all to the portal when reconnected.

    That view only shows 15 minute data. Click on the Chart icon near the top (you didn't share it with others), then select the inverter on the left, graph say AC power, zoom into an hour on any day....
    on the sample from one of our sites you can clearly see data point at 12:20, 12:25, 12:30, etc....

    Pvoutput is 15 mins unless you donate to them, then you can turn in the 5 min updates.
    Solaredge over Ethernet should be 5 min with or without pvoutput though.

    If so they would have a financial incentive to NOT provide you with a way to increase the amount of data since they're paying the cellular carrier for each extra byte sent.
    My guess would be the firmware tells the cellular kit what to do for a refresh rate, and it's possible to change it via a firmware change. But it's not something they want to give an end user.
