Is there any documentation of the parameters provided in the csv download from the Advance dashboard related to my system?

I have downloaded the csv reports from my neighbours system via the Vitron portal. I have searched for documentation on each of the fields but not found anything and hoping that someone could help.

For example looking at VE.Bus System [0] and Input phase 1 I would expect Power to be equal to Current multiplied by Voltage. The latter VI calculation fluctuated wildly where Power is relatively well behaved. I suspect that the Current is simply an instantaneous value where Power is averaged.

I am working on evaluating different Tariffs from our local municipality who have now introduced Time of Use (TOU) Tariffs on top of the normal energy tariffs. The municipality is encouraging the TOU tariffs which better reflect their costs.

A possible Win-Win for User and municipality.

Thanks, John

Given your use case of analysing energy consumption at different times of day, have you tried working with the kWh download?

I think it will be more useful to you.

Hi Guy,

Thanks for the quick answer. I think you are 100% correct. I was not sure what the difference was between the different csv files.

I have a slight logistical problem as the download link goes to my neighbours email and he does not always notice in time to download and forward. That is why I only got the one report so far.

So you've answered the immediate question, but is there any documentation for the download fields?

There is not extensive or specific documentation for the advanced download, as far as I know.

Regarding Current, Voltage and Power, for AC, the relationship is not as easy as P = IV. There is another component called power factor which introduces reactive power, as compared to real power.

There is more information in Chapter 6 - AC Wiring in Margreet's Wiring Unlimited - https://www.victronenergy.com/upload/documents/Wiring-Unlimited-EN.pdf

Are there any others you would you like further info on?

Thanks again Guy,

I have now managed to get the kWh download.

Time steps are every 15 minutes, I presume the kWh are for the previous 15 minutes.. Can anyone confirm?

I would also like to know how to work out total kWh to Grid and kWh from Grid as they are metered at different rates.

My assumption is:

kWh to Grid = PV to grid + Battery to grid
kWh from Grid = Grid to battery + Grid to consumers

Can anyone confirm?

Thanks again,

The list of headers are as follows:

timestamp (TimeZone details)

Solar Yield (delta) (kWh)

Grid to battery (kWh)

Grid to consumers (kWh)

PV to battery (kWh)

PV to grid (kWh)

PV to consumers (kWh)

Battery to consumers (kWh)

Battery to grid (kWh)

Genset to consumers (kWh)

Genset to battery (kWh)

I did some checking against the portal and the kWh are actually for the subsequent 15v minutes as shown under period above.

We'll get this documented by hook or crook :-)
