is the one which is directly connected to the external mater or current transformer. Only one
single MASTER device is allowed in a multi-charger system controlled by the same meter
•
Charging modes (photovoltaic support):
o FAST: the charging process both uses the grid and the green energy (PV and storage)
at their maximum available value
o
ECO: the charging process is supplied only by the green energy, if the available
current is 6 A or more. If the available green current is below 6 A, the grid will add
the necessary power, as an integration, in order to make the system charging at 6 A
o
ECO+: the charging process is supplied only by the green energy, if the available
current is 6 A or more, but the charging current is limited at 6 A. If the available
green current is below 6 A, the grid will add the necessary power selectable in the
range 0-5 A only, in order to make the system charging at 6 A. If the available
current, even adding the maximum grid contribution, remains below 6 A, the charge
process is stopped

8.2.14 1-phase meter configuration
The 1-phase meter configuration is performed through its ModBus interface.
In alternative the meter can be configured by means of its frontal button:
• switch the device on simply connecting it to the 1-phase power supply
• push the frontal button for at least 5 s
• during this time the display values rotate in a fast sequence
• release the button
• wait for the protocol indication to appear (“ModBus should appear)
• push the button once: the display shows the serial interface parameters. Select 8n1 = 8
bits, no parity, 1 stop bit
• wait for the new display indication (the ModBus address), this happens automatically,
no needed actions
41
•
•
When the ModBus address configuration page appears, push the configuration button
in order to have address = 2 (it is sufficient pushing the button twice, in case the value
is overpassed it is necessary to increase the address value up to its wrap-up value and
restart from 1)
After that, the baud rate is automatically set to 9600, no action needed

The external meter is connected to the
charger through an RS-485 bus.
Picture
The RS-485 terminal blocks can be
reached removing the charger cover
and then by removing the inner cover
which protects the supply terminal
blocks.
The RS-485 wires are connected to the
bus connector (terminal block) on the
charger, as presented in the picture
(boxed in red).
The RS-485 cables are inserted through
the same access path used for the
supply cables.
the power supply must be
disconnected in this phase
2
The RS-485 signals from the meter shall
be connected as in the picture
respectively for
• RS-485 A
• RS-485 B
These signals must be connected to the
terminals 24 and 25 of the meter
(please see the meter connection
scheme).

After the external meter is connected,
the charger must be closed again with
its covers. This is extremely important
for functional and, mainly, for safety
reasons.
Important: the other loads have higher priority than the charger
43
Important: the charger parameters must be configured only by qualified personnel
8.2.16 Connection to the external current transformer
In alternative to the digital meter, as presented in the previous chapter, a current transformer
can be used.
The current transformer must be connected as in the following:

After the external meter is connected,
the charger must be closed again with
its covers. This is extremely important
for functional and, mainly, for safety
reasons.
8.2.17 MASTER – SLAVE connection
In this type of connection two chargers share, in a balanced way, the available power between
them and the rest of the loads in the system.
One of the chargers is identified as the MASTER and it is connected to the external power meter,
which measures the total power flow in the system.
The other charger, defined as the SLAVE, is connected to the MASTER through the ethernet
cable and receives by the MASTER the instruction about how the power must be shared

8.2.18 MASTER-MULTI-SLAVE connection
In this type of connection, the chargers share, in a balanced way, the available power between
them and the rest of the loads in the system.
One of the chargers is identified as the MASTER and it is connected to the external power meter,
which measures the total power flow in the system.
The other chargers, defined as the SLAVEs, are connected to the MASTER through the ethernet
cable or by the wifi interface (in both cases a network equipment is needed) and receive from
the MASTER the instructions about how sharing the power.
The sharing algorithm between the chargers follows a priority scheme privileging the first
charger which starts recharging.
An example of the sharing algorithm, considering a four-charger scenario, is presented in the
following paragraph table.

Load

Sharing algorithm in MASTER-MULTI-SLAVE connection
The S1, S2, S3, S4 chargers, in sequence, start their charge operations at the T1, T2, T3, T4 times
respectively.
In this example we consider to have a maximum available current of 50 A
The available current will be shared between the chargers. The charger which starts before has
higher priority (a higher available current value).
The remaining chargers, which start later, will have a proportional, but decreasing, current value
assigned.
