Solar users like myself with hybrid systems that have a battery and critical loads powered directly by the inverter have been asking that question for a while…

The answer has been that the Vue Gen2 Hardware can to bidirectional measurement, that it is not yet supported in the Software, but will be in the future.

We are all awaiting for it ! 🙂

Without connection to the internet, you get no data and it is lost when reconnecting. Only the total is supposedly saved, but not the details.

Numerical data like what the Vue transmits are a VERY small internet load, so I don’t think you should worry about data usage.

When you do a CSV export, you get a Zip file with 4 files

The day increment values, the hour increment values and the seconds increment values.

In each file, the first column is the time stamp, followed by one column per CT, then each line has the kilowatt reading for the corresponding CT and time stamp

[scrambler]

That should be considered a Bug and fixed in the future. We should keep both decimals

I you initialized the system originally with the solar CTs installed in the same direction as the other one, then this is likely your issue.

My advice would be to:

• Power off the Vue.
• Delete the device from the app
• Switch off solar
• Reverse the solar CTs (opposite direction as the load CTs)
• Leave solar off, then add the Vue again in the app, and power it up (solar off).
• Let it redo the whole initialization.
• Then when instructed switch on the solar breakers.

Actually amps are displayed with 2 decimals on small value, so there should not be any rounding on the displayed value at all

[scrambler]

Solar CTs are supposed to be installed in the reverse direction from load CTs, did you do that?

Also did you make sure the Solar breaker(s) where switched off during the initial powering of the Vue?

Did you check if using straight extension cable would pass in the conduit?

What about putting a larger conduit?

Glad to hear that, and if this is the case, marketing wise, you would be better off limiting the minute data when that plan is actually available.

People are more likely to subscribe when they feel the pain. By removing the ability now when there is no alternative, they will be forced to get use to doing without the data, and are less likely to subscribe when an alternative actually becomes available 🙂

If not, please consider restricting to 8 days until the subscription is available (instead of 3), so we can do a weekly download. Every two days is just not practical.

Again, if people cannot get the data in a practical way for a long time, they will have to get use to not using it and many will be less likely to subscribe…

My 2 cents

This may just be some noise on the CT.

5W is around their precision limit

I forgot to add that last post and not last thread (if this is what is being shown) is really what is useful.

Ideally, if you could have a What’s new page showing all the new post since the last visit, that would be ideal for people who want to quickly check the forum for new discussion or answers.

This help engage people more, as they can quickly see what is going on and be tempted to participate.
If one has to go drill down into every sub forum to see if there are new elements, they are likely to skip.

As far as I know you can set the Multiplier to whatever you like.

From what I read, this was actually used for Gen1 that used a fixed 120V reference to compute power, allowing people to correct the power calculation to account for a different value than 120V.

I created the same difference table with the Feb 5th seconds data.

I calculated the minute data from the seconds data, and made the difference with the downloaded minute data. The blips illustrated in the first post appear across all CTs that have a non zero reading.

[scrambler]

To detect all discrepancies between the hourly report and the minute report, I recalculated all the hourly data from the minute data in excel and made a difference table between the recalculated hourly data and the downloaded hourly data, and the error in the downloaded hourly data appear clearly, always over two consecutive numbers, with equal deviation up and down.

This is the same phenomenon that was initially detected and reported in this thread, between the seconds data and the minute data.

So I assume all starts with the seconds data that is correct, then when minutes data is calculated that error occurs occasionally, and then when the Hourly data is calculated, the same happens (I have not check daily data yet)

[scrambler]

FYI,

It seems the same issue is happening between Hours interval reporting and Minute interval reporting.

Sometimes the hour data will deviate from the minute data in the same way as described above. One value will be higher than it should the next below what it should, then back to normal.
