§14a EnWG with Easee
Check whether §14a applies to your installation, find the right Easee solution and understand how the control path is implemented.
If you are planning or installing an Easee charging installation in Germany, §14a EnWG may place requirements on how it can be controlled by the grid operator.
This article takes you from assessing your installation and choosing the right Easee solution through to technical implementation and functional testing.
Already know that §14a applies to your installation?

§14a EnWG allows the distribution system operator to temporarily reduce the grid-effective power consumption of certain controllable devices when the local grid is at risk of overload. Check these four criteria first.
Non-public charging point
For example, at a private home, apartment building, workplace or restricted company site.
Grid-connection capacity above 4.2 kW
The threshold refers to the charging point’s connection capacity, not the power used in one charging session.
Connected to the low-voltage grid
The connection may be direct or indirect behind the building’s grid connection point.
Commissioned on or after 1 January 2024
Transition rules may apply to older installations and to installations that are replaced or materially changed.
4.2 kW is not a permanent charging limit
With direct control, a minimum grid-effective power of 4.2 kW must generally remain available to the controllable device. If several controllable devices are coordinated through an energy management system, the specified aggregate value and simultaneity factor apply.
For existing installations and special cases, the responsible grid operator determines which transition rule, control technology and process apply.
02How does §14a work with Easee?
The control request travels locally along a physical signal path to the Easee charging installation.
Receive the control request
An external control device, such as an FNN control box or ripple control receiver, provides the grid operator’s request.
Transfer the contact state
A potential-free contact transfers the state to the selected metering solution. Contact logic and wiring depend on the device and the grid operator’s requirements.
Provide the control value locally
The metering solution and Equalizer provide the configured limit to the relevant primary chargers.
Adjust charging power
The chargers apply the limit while the request is active. Afterwards, the normal site and circuit limits apply again.
Physical control path
EEBUS is not supported for this Easee §14a configuration. A different digital interface requires separately documented and approved project planning.
03Which Easee solution do I need?
Select the metering solution based on the size of the installation. The table shows the matching configuration path.
| Solution | Installation size | Next step |
|---|---|---|
| Equalizer Amp | Up to 100 A | One control level in the Installer App; two to four control levels through Easee Support |
| CVM E3 mini | Above 100 A and up to 250 A | Use the Modbus configuration and matching project drawing |
| Janitza UMG 604 Pro | Above 250 A | Use the Modbus configuration and matching project drawing |
Using the Equalizer Amp?
Confirm how many control levels the grid operator requires, then select the matching approved drawing. One control level is configured in the Installer App; two to four control levels require Easee Support.

Using a Modbus meter?
CVM E3 mini and Janitza UMG 604 Pro use separate wiring and control states. Use only the drawing that matches the selected metering solution and the confirmed project plan.
04Which local connection is required?
The Equalizer must be able to transfer the control value locally to the relevant primary chargers.
| Installation | Local communication path | Requirement |
|---|---|---|
| One charging circuit | Easee Link RF can be used | Reliable radio coverage between the Equalizer and primary charger |
| Several charging circuits | Shared local WiFi | The Equalizer and all primary chargers use the same local network |
| Internet | Not required for the local §14a control path | The required local RF or WiFi connection remains available |
WiFi is not the same as internet
An offline status in Easee Cloud does not automatically mean that the local control path has failed. Conversely, an online status does not confirm that the Equalizer can reach every primary charger locally. Always check the local communication path that is actually used.
05Installation and commissioning
The steps below define the high-level installation sequence. Use the linked technical documentation for wiring and configuration, following the selected solution and the grid operator’s requirements.
Only an authorised electrician may carry out the installation
The metering solution, external control device and charging installation must be installed and commissioned according to the current product guides and applicable electrical regulations.
Install the metering solution
Install the selected metering solution, sensors, power supply and Equalizer according to the current product guide.
Connect the external control signal
Wire the potential-free contacts exactly as shown in the selected Amp drawing or confirmed Modbus project drawing.
Establish the local communication path
Confirm the required local path: Easee Link RF for one charging circuit or shared local WiFi for several circuits.
Configure GPI Ripple Control
Configure the confirmed control values and contact logic in the Installer App. Two to four Equalizer Amp control levels are set up through Easee Support.
Test a real control request
Trigger the external signal and document how the complete charging installation responds.
06Verify operation
Do not rely on an App or Cloud status alone. What matters is how the installation responds to a real external control request.
Check normal operation
Confirm that the measurements, charging permission and power limits are plausible during normal operation.
Trigger the control request
Activate the real external contact for each configured control level.
Check the response and local path
Confirm that all affected charging circuits apply the expected control value locally and return to normal when the request ends.
Document the result
Record the signal state, control level, local connection and resulting charging power in the commissioning report.
Verification complete
Commissioning is complete when the real external signal has been triggered, the local communication path has been confirmed and the resulting charging power has been documented.
The installation does not respond as expected?
Record the metering solution, number of charging circuits and control levels, contact state, local communication path and observed charging power. These details are required for a targeted analysis.
