Elli ID.Charger 2

Installation

1. 1Ensure the Elli ID.Charger 2 firmware is at least version R12_R04.004.045.303 and update if necessary via the wallbox web configuration.
2. 2Activate the Modbus server in the wallbox web configuration, decouple any connected Modbus meter, and deactivate the Energy Management System.
3. 3Deactivate all smart charging functions (forecast-based, PV-surplus, market price optimized) in the Elli or Smart Charging App.
4. 4Connect the ModbusCloud gateway (MCG or MLP series) to the same local network as the Elli ID.Charger 2 and ensure Modbus TCP connectivity on the correct IP address and port.
5. 5Import 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.
6. 6If 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

01

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.

02

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.

03

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.

04

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.
