EVSE- Sub-Distribution Limit (L1/L2/L3) (A) – Maximum available current intensity for the complete load management clus-
ter
This parameter is used to configure the maximum current intensity for each phase which is provided to the entire charging cluster. This
represents the absolute upper limit of the load management and must not exceed the values available in the installation for the com-
mon connection point.
NOTE
If multiple charging clusters are used at a common con-
nection point, the total value of all charging clusters
must not exceed the available current intensity.
Default Value: 16, 16, 16
Operator EVSE- Sub-Distribution Limit (L1/L2/L3) (A) – Maximum current intensity to be distributed for the complete load
management cluster
The parameter configured here must not exceed the values of the "EVSE Sub-Distribution Limit", and should be below the "EVSE
Sub-Distribution Limit" parameter. This parameter can also be used to adjust the value actually assigned to the charging cluster during
operation.
One OCPP back end can adjust this value dynamically and the local load management can be integrated into a back end-based load
management. The back end cannot set any parameters that exceed the "EVSE Sub-Distribution Limit" parameter.
Default Value: 16, 16, 16
External Meter Support – Using an external electricity meter to support the load management
The Webasto Live supports the integration of an external default value for the local load management. To do this, connect the external
meter to the master charging station for the load management using the external Modbus connection and configure the external meas-
uring device with the following parameters. Ensure correct polarity of the connection:
Parameter Value
device ID 2
Baudrate 9600
parity Even
stop bit 1
word length 8
Polarity D and /D
Termination Yes
Contact the manufacturer of the electricity meter for details on configuring the parameters of the external measuring device.
Default Value: Off
NOTE
Use three-phase measuring devices only.
Meter configuration (Second)
This parameter is used to configure the model of the external meter. The Webasto Live supports different types of external meters. If
your available meter type is not listed, then please consult the manufacturer of the electricity meter. Webasto is constantly checking the
functionality of other electricity meters so that electricity meters that are not on the list can also be used.
Main Distribution Limit (L1/L2/L3) (A) – Maximum available current intensity on the external meter
This parameter is used to configure the maximum upper limit of the current intensity that must not be exceeded at the external meter.
By measuring the real draw, the remaining available current intensity is distributed in the charging cluster taking into account the opera-
tor EVSE-Sub Distribution Limit as well as the EVSE-Sub Distribution Limit.
Default Value: 100, 100, 100
External Meter Disconnected Fallback (L1/L2/L3) (A) – Limit in case of a connection failure of the external meter
In case of a connection failure between the master and external meter, this parameter can be used to define a maximum upper limit
that is available for distribution from the master charging station to the slave charging stations.
Default Value: 9999, 9999, 9999
External Meter Location – Reading from the external meter incl./excl. the charging cluster
This parameter can be used to define whether the reading delivered by the external meter already contains the volume of purchased
electricity from the charging cluster or whether this must still be added in order to not exceed the main distribution limit.
Default Value: Including EVSE Sub distribution
