6.2 Stand Alone Battery Front Panel Control
6.2.1 Start Battery
Short press the power button for one second. The GREEN RUN light should come on. The battery has been activated normally.
6.2.2 Shut Down Battery
Long press the power button for five seconds. The GREEN RUN light should go off. The battery has been shut down normally.
6.2.3 Low Battery – Force Charge
Prerequisite:
The
VOLTAGE
between the battery B + and B- terminals is
ZERO
and the
PANEL LIGHTS ARE OFF
. Battery is in
“Shutdown State”.
Preparation condition before forced charging:
Connect the charger or the inverter with charging capability to the B+ and B- of the
battery box to ensure charging capacity.
Forced charging approach:
Short press the battery power button, the battery RUN light will flash green, which means that the battery
is entering the compulsory charging mode. If the battery receives an adequate charging power (above 10 Amps/58V) within 90
seconds from pressing the button, the battery will continue to charge normally until a stable state is reached.
If the battery does not receive adequate charging power within 90 seconds after pressing the button, the battery will enter the
shutdown mode once again.
During the forced charging period the low battery LED will be steady orange up to an SOC of 10% at which point the low battery LED
will go out.
6.3 Parallel Battery Configuration
1.
The voltage difference between any of the batteries in the stack must not be greater than 2V. Otherwise, the BMS will not
allow the batteries to be activated in a parallel connection.
2.
SOC of each battery in the stack must be the same (check SOC as individual battery before parallel connection)
3.
The power cabling between the batteries is in accordance with section 5.6 of this manual.
4.
All DIP switches are configured in accordance with section 5.5 of this manual.
5.
The RS 485 inter battery data connections are properly connected as per section 5.6 of this manual. The data connection
“daisy chain” must start from port-B of the master battery (do no install the RS485 on the port-A of the master battery, it
will occur in a fault)
6.
Connect the CAN port of the master battery with the CAN port of the inverter and make sure that the communication is
working properly by checking the inverter display
7.
Before activating the system, the operator should check the cable connection carefully and make sure that all safety
procedures are respected. Check the inverter settings and connection before turning on. In case of an inverter without
communication make sure to set the voltage and current value as per the charge/discharge parameters provided in this
manual.
6.3.1 Activation of Parallel Batteries (From Master to Slave#4)
Short press the Master power button for one second. The GREEN RUN light should come on. The battery has been activated normally.
Short press the Slave#1 power button for one second. The GREEN RUN light should come on. The battery has been activated normally.
Short press the Slave#2 power button for one second. The GREEN RUN light should come on. The battery has been activated normally.
Short press the Slave#3 power button for one second. The GREEN RUN light should come on. The battery has been activated normally.
