Hello team,

I want to request modbus compatibility with Wallbox chargers. It is required to use specific modbus address for supporting the meter integration with Wallbox EV chargers.

Here there is the modbus addresses of other meter vendors that are compatible with Wallbox:

It seems both vendors uses the same modbus addresses:

4000 for serial number

5002 for V1 voltage

500D for Current

5012 for Total Active Power

Regards,

Hi :

Whether your wallbox charger support OCPP?

If so ,please refer to 

https://www.iammeter.com/docs/ev-charger-quickstart

It is easy to integrate your ev charger into IAMMETER via OCPP.

The OCPP support from iammeter is only available when the meter is configured as inverter to measure FV power. But if you are using the meter to measure Grid, OCPP is not an option.

Hi:

"The OCPP support from iammeter is only available when the meter is configured as inverter to measure FV power. But if you are using the meter to measure Grid, OCPP is not an option."

Of course not.
When you use the OCPP from the IAMMETER cloud, the meter should be installed on the grid side, not the inverter side.
Because the main aim is to keep the exporting Kwh to the grid as less as possible.
