10.1.1 AZZURRO HV BATTERY CONNECTION – 1 BATTERY TOWER
Batteries
are connected
IN Parallel
to each other:
•
Positive input (+) of
battery 1
connected to positive input (+)
of
battery 2
.
•
Negative input (-) of
battery 1
connected to negative input (+)
of
battery 2
.
•
…..
•
Positive input (+) of
battery N-1
(second-last) connected to
positive input (+) of
battery N
(last).
•
Negative input (-) of
battery N-1
(second-last) connected to
negative input (-) of
battery N
(last).
Connect each device to the ground system.
Power and communication connections between batteries and BDU
Battery module
(ZZT-BAT-ZBT5K)
BDU
(ZZT-ZBT5K-BDU)
NOTE: The Azzurro HV batteries are batteries with 400V DC output,
therefore, unlike the WeCo and Pylontech batteries they must NOT be
installed in series but in
PARALLEL
.
Each tower of battery modules consists of a
BDU
connected in parallel
to multiple battery modules.
Communication connections between batteries and BDU:
•
COM-IN of the
BDU
LINK PORT IN of
battery 1.
•
LINK PORT OUT of
battery 1
LINK PORT IN of
battery 2.
•
…
•
LINK PORT OUT of
battery N-1
(second-last)
LINK PORT IN of
battery
N
(last).
•
LINK PORT OUT
of battery N
(last)
Terminating resistor
.
The
BDU
is connected to
battery 1
:
•
Negative input (-) of the
BDU
connected to
negative input (-) of
battery 1
.
•
Positive input (+) of the
BDU
connected to
positive input (+) of
battery 1
.
Connect each device to the ground system.
