Expert portal configuration for Smappee Energy

Please note this is the expert portal configuration for 3 phase and single phase + solar energy monitors. These monitor's serial numbers start with 1007.

 

Please see the following article on how to access the expert portal:

How to access the monitor’s expert portal?

 

After successfully logging in to the expert portal, go to the tab “configuration”.

You should see the screen below. Please see the legend on the next page for instructions on what everything is used for.

 

Overview and legend

  1. The high Level configuration of the monitor.
  • 3 phase configuration: star (3 phases + a blue neutral wire or delta (3 phases without a blue neutral wire).
  • Frequency: this depends what country you live in. Either select the correct frequency or leave on auto detect.
  • Auto-detection: always Turn off.
  • Monitor mode: we recommend choosing one of the three configurations below that applies best to you. Please do not use any others as they are for testing purposes or configurations in America.
    • Three phase 120d
    • Single phase
    • Single phase + solar
  • Phase to input mapping: this is the most important setting for a correct configuration. The 3 numbers represent the 3 phases of your installation (in a three phase installation). The first phase of your installation is not necessarily the first phase on the monitor as the Smappee monitor recognizes the phase from the power socket it is connected to as the first phase (the reference phase). This is the main reason why the monitor is not measuring your installation correctly.
  1. The voltage reverser

The voltage is measured by the power socket, since the power socket is AC it doesn't matter in which direction you plug in the power plug of the monitor. This does however have an effect on the Amperage measurements. Reversing this reverses everything, and would be the same as if you would pull out the power plug, turn it around and plug it back in.

  1. The measured active values

Here you can see what values are measured by each clamp connected to the Smappee. You can see what load the phase represents and to what input of the Smappee they are connected. You can also see if an individual reverse is active on the phase and how good the quality of the measured power is (cos fi).

We recommend never using individual phase reverse to correct configurations. The only recommended use for this feature is to use it when you are 100% sure that particular clamp is connected with the arrow pointing in the wrong direction.

  1. The detected connected CT’s

Here you can see in what Smappee input a clamp is connected and if the clamps are correctly detected.

  1. Save and undo button
  • Save changes and restart: this will save any changes you have made to the configuration and restart the monitor to apply them. The restart process takes about 5 minute and the expert portal will be unavailable during that time.
  • Undo changes: this will undo any changes you have made to the configuration.

 

How to correct the configuration.

- Check the physical configuration according to the installation manual (https://www.smappee.com/smappee-manuals/)

--> Direction of CT's!

--> CT's need to be clicked arround the correct wires and connected to the correct inputs

- Check the high level configuration (step 1, described above)

- Now, please turn on some heavy consumers in your household such as a water boiler, microwave, oven etc. This will greatly help us configure the monitor as the cos fi will be much higher.

When you turn on a device with a heating element such as a water cooker, the cos fi should increase to +90%

 

Lets take this monitor for example:

mceclip1.png

The high level configuration is correct, it’s a three phase installation set to phase to input mapping 1-2-3.

This means the monitor is measuring phase 1 in input 1, phase 2 in input 2 and phase 3 in input 3. This is the default configuration of the monitor.

In this particular case of the screenshot above the configuration is clearly wrong. The cos fi is very low which means the quality of the measured active power is very bad. This is usually an indicator that the configuration is wrong, especially when measuring high powers (1000w+).

In this particular installation there is also a negative consumption (on load 3) which is not possible.

We also notice that there are 3 individual phase reversers active. One on each phase. As mentioned previously we highly recommend never to use individual phase reversers to correct configurations.

 

In order to fix this configuration, we will have to change the phase to input mapping until we find a configuration with much better cos fi, the screenshot below shows the changed configuration:

mceclip2.png

After some trial and error, it seems that the phase to input mapping 3-1-2 is the correct configuration.

Cos fi is looking much better and no negative values are shown anymore. For this installation to be by the books, we could also deactivate the individual phase reverser on all three phases and run the voltage reverser to inverse the voltage itself.

 

Notes

  • In a delta installation every consumer is connected between 2 phases, which means if you turn on a big consumer, you should see 2 phases react to it. If the consumer is connected between phase 1 and 2 and has a power of 1000W. then you should see an increase of 500W on phase 1 and 500W on phase 2 of the active power.
  • In a single phase + solar installation, you will see 3 values even though only 2 clamps are connected.
    • Grid: import/export measured by the clamp connected to input 1 of the monitor.
    • Solar: Solar production measured by the clamp connected to input 2 of the monitor.
    • Load: The calculated true consumption of your household by adding the import or deducting the export from the generated solar production.
  • After the (re)installation of the monitor or after a power cut, it is possible the monitor will not measure correctly. This is probably due to the configuration of the monitor.
