OCPP MID Meter Setup Guide

This guide provides steps for setting up a MID meter for OCPP metering. Follow the instructions carefully to ensure proper functionality.

Purpose and Setup of MID Meter for OCPP

• The MID meter connected for OCPP metering enables the charger to communicate with backend systems and monitor energy consumption according to MID standards.
• Only one MID meter should be assigned for OCPP metering in each installation to avoid conflicts.
• All Morek Smart AC chargers have integrated meters for OCPP communication with ±1.5% accuracy. If that level of accuracy is sufficient, there is no need for an external MID meter connection.

Connecting the MID Meter

• Ensure the MID meter dedicated to OCPP is set to Address 1 within the meter itself. The charger will automatically use Address 1 for this communication once the connection is enabled through DIP switch 3.
• Connect the MID meter to the charger via the RS485 connection, using the main PCB board communication terminals. The meter connections are on the far left (first terminal from the left) and connect to the first connection on both terminals.
• Locate the charger’s DIP switch and turn switch 3 ON.

If DLM functionality is required, a second MID meter must be used. This ensures that the OCPP metering and DLM functions operate independently without interference.

Using CTs with OCPP MID Meter

Current Transformers (CTs) can still be connected and used if load balancing is needed alongside OCPP metering. This option enables load control without requiring a second MID meter solely for DLM. Note that it is not possible to use a HUB to control multiple charging stations for DLM functionality. Please refer to the DLM Setup Guide for detailed instructions.
