Elli ID.Charger 2
Controls maximum charging current for Elli ID.Charger 2 wallboxes via Modbus TCP.
This template integrates the Elli ID.Charger 2 wallbox via Modbus TCP. It reads charging state, per-phase RMS current, and total power. It also allows control of the maximum charging current through a writable register.

Use cases
- Monitor per-phase charging current and total power on a live dashboard for each Elli ID.Charger 2 installation.
- Set the maximum charging current remotely to balance load across multiple consumers on a single grid connection.
- Create an alert when the charging state changes so the installer or end customer is notified when a session starts or stops.
- Log energy consumption over time to generate monthly or quarterly charging reports for fleet or facility managers.
- Integrate multiple Elli ID.Charger 2 units into a single ModbusCloud project for centralized load management across a parking facility.
Installation
Ensure the Elli ID.Charger 2 firmware is at least version R12_R04.004.045.303 and update if necessary via the wallbox web configuration.
Activate the Modbus server in the wallbox web configuration, decouple any connected Modbus meter, and deactivate the Energy Management System.
Deactivate all smart charging functions (forecast-based, PV-surplus, market price optimized) in the Elli or Smart Charging App.
Connect the ModbusCloud Gateway to the same local network as the Elli ID.Charger 2 and ensure Modbus TCP connectivity on the correct IP address and port.
Import the Elli ID.Charger 2 template in the ModbusCloud platform and assign it to the gateway, verifying that charging state and current readings appear correctly.
If using single-phase charging, confirm the phase setting in the wallbox onboarding wizard or in the charger web configuration under charging settings.
Things to watch for
Which firmware version is required on the Elli ID.Charger 2?
The wallbox firmware must be at least R12_R04.004.045.303. Earlier versions may not expose the required Modbus TCP registers. Check and update the firmware via the wallbox web configuration.
Why am I not receiving any Modbus data from the charger?
Make sure the Modbus server is activated in the wallbox web configuration. Also verify that the Energy Management System is deactivated and any connected Modbus meter is decoupled. Smart charging functions must be turned off as well.
What is the current conversion formula used in the template?
The template uses I1*1000/(400*SQRT(3)) to convert the register value into a usable current reading. This conversion is already built into the template.
Can I use this template for both single-phase and three-phase charging?
Yes. The template supports both configurations. Single-phase allows 6 to 16 A (approx. 1.4 to 7.4 kW) and three-phase allows 6 to 16 A (approx. 4.2 to 11 kW). Set the phase mode in the charger web configuration or via the onboarding wizard.
