=== Max power from grid ===
It is very important to set this parameter correctly in the master charger if you want to use DLM. This parameter shows how much of current you have in the circuit you want to balance. That means you have to set as much as this current can have amperes. Usually it should be the same current as the breaker tripping current. If for example in the master charger you will set lower current, DLM might not work and charger might not even start charging process.
For the slave charger, this parameter is not as critical. It is advisable to set it to a maximum of 16 A (for 11 kW chargers) or 32 A (for 7.4/22 kW chargers).
=== General meter settings ===
If you want to enable dynamic load management with a smart meter, it is important to correctly configure the general meter settings.
# Energy meter type: You need to select the type of smart meter (1-phase/3-phase). Please note that you can use a 1-phase charger even if the meter is 3-phase.
# RS-485 baud rate: This information can be found in the meter settings accessible through the meter display. If the client cannot locate it, it is recommended to refer to the smart meter manual.
# RS-485 parity/stop bit: Similarly, this information can also be found in the meter settings. If the client is unable to find it, it is advisable to check the smart meter manual.
These settings must be configured for all chargers in the circuit, regardless of whether they are slaves and have direct communication with the meter. These settings establish the communication protocol between the master-slave and master-meter.
=== Dynamic Load Balancing ===
To access the DLM functionality, the user must first enable the DLB functionality.
# Measuring device: The meter should be selected. For UK chargers, it is possible to choose CT clamps.
# Energy meter address: This information can be found in the meter settings accessed through the meter display. If the address cannot be located, it is recommended to consult the smart meter manual.
# Current update interval: By default, it is set to 3 seconds. However, there may be cases where the user needs to increase this value. For instance, if there are significant distances between the chargers and the smart meter or if there are numerous interconnected chargers.
