Power flow portlet

Last modified: 22 Jul 2025

Basic info

Item in the Portlet center
Description	The Power flow portlet displays the real-time power flow and direction between your system’s energy nodes, such as PV generation, grid, consumption, and batteries.
Prerequisites	Configure the portlet once by selecting Start configuration and select all relevant data sources for the energy nodes there. This will automatically create all relevant terms required to display the portlet.
Portlet properties	System portlet: The portlet can be added at the SYSTEM LEVEL. Dynamic portlet: The portlet is updated when you select a different system name from the systems list.
Further details	Data sources for energy nodes Configure each energy node’s data source at SYSTEM LEVEL under System configuration > Calculations > Power flow. Terms The terms used for this portlet are the following: E_Z_EVU (PV generation) PF_P_CON (Consumption) PF_P_GRID (Grid) PF_P_BAT (Batteries) Edit each of these terms to your needs at SYSTEM LEVEL under System configuration > Calculations > Terms > Term editor. See also Terms

Troubleshooting

Problem

Grid flow directions are reversed.

Cause

The “reference arrow direction” on your data logger or meter has been incorrectly configured. This causes the power transformer to reverse the values for grid import and export and results in an incorrect power flow portlet.

Solution

At SYSTEM LEVEL, go to System configuration > Calculations > Terms > Term editor.
In the table of terms, navigate to the term PF_P_GRID and select Edit.
Change the Formula: Add -(…) parenthesis and a minus around the formula.
Select Save.

The values are reversed now and the grid flow direction in the power flow portlet is corrected.

Note

Alternatively, correct the configuration on your data logger or meter, or ensure the power transformer is connected properly. BLUE'LOG ONLY If using a blue’Log, see Meters for correcting these configurations.

Note that the historical data will still be incorrect in this case.
