New page

== Abstract ==

The so called "Energy import" is inspired by [http://PVOutput.org PVOutput] energy import chart.

If the generated power (Net power) is greater than the consumption, the energy import is no more raising.

== Charts ==

First there are 2 areas, the overall production (E-Total, blue) and overall consumption (Power consumption, red) over time.

Then the actual inverter yield (P<sub>AC</sub> Blockhaus, blue) and actual consumption (S0 consumption, dashed red).

The interesting part is the black Energy import spline, which stays by 2998 Wh since 07:08 here. This means, since 07:08 there is no energy import, only export.

'''''Please note:'''''
* Arrange the channels according their units to the axes!

== Definition ==

Let's start with the meter channels for the areas.

I decided to put all "watt" channels on the left and all "watt hour" channels on the right axis.

=== E-Total ===
'''Definition'''

[[File:EnergyImportE-TotalChannel.png]]

We define here a positive cost per watt hour to see later the income amount generated.

(We get here 28.74 cent per kilo watt hour == 0.0002874 Euro per watt hour)

'''Chart settings'''

[[File:EnergyImportE-TotalChart.png]]

=== S0 consumption and Power consumption ===
'''Definition'''

Here we need also a special helper channel, the [[SensorToMeter|Sensor to Meter]] proxy.

We have to convert the actual power consumption (Power sensor in watt) into an meter channel (in watt hours) which also sums up the data.

Power consumption [Wh]
|-> Power usage [W]

The Power usage is a normal power [[sensor]] and the Power consumption is the proxy to convert the sensor to a meter channel!

[[File:PowerUsageChannel.png]]

'''Chart settings'''

[[File:PowerConsumptionChartSettings.png]] [[File:PowerUsageChartSettings.png]]

For Power consumption we are also interested in peek powers used.

=== PAC ===
'''Definition'''

Simply the actual generated inverter power:

[[File:PacChannel.png]]

'''Chart settings'''

[[File:PacChartSettings.png]]

We are also interested in the max. value.

=== Energy Import ===
'''Definition'''

Here we need a channel based on the [[Import / Export channel type|Import / Export]] channel type.

[[File:EnergyImportChannel.png]]

We define here a negative cost per Wh to see later the amount consumed.

(We pay here 23.44 cent per kilo watt hour == 0.0002344 Euro per watt hour)

'''Chart settings'''

== Result ==

Now we can put this all together:

[[File:EnergyImportTree.png]]

In the Charts view we will have this:

[[File:EnergyImportChartsTree.png]]

* We have '''consumed''' 4.6 kWh, but '''bought''' only 2.8 kWh and have a '''win''' of € 4.79 at the moment!
* The '''Amount''' column will only be filled for [[Channel attributes#Meter|meter]] channels.
* The '''Cost''' column will only be filled for meter channels with [[Channel attributes#Cost|costs]] defined.
