7. Battery use information
7.1 General instructions
• Do not leave the battery in a SOC ≤50% for more
than 3 months.
•Charging is not allowed at temperatures ≤0oC
(+32oF). The BMS will automatically reduce the
permitted charging current in low temperatures
(0oC to +10oC / +32oF to +50oF) and completely
stop any charging current at temperatures ≤0oC
(32oF).
7.2 Battery Function
•Charging is performed automatically using
Inverter/Charger that is connected to the
Li.ONESS Power Unit / PBT unit (where
applicable), within specied temperature limits
(0oC to +45oC / +32oF to +113oF), only to a dened
voltage limit, with a current which is supplied
from the charger and regulated from the BMS.
The limits for Voltage, Temperature and Current
are set in the BMS without the intervention of the
user.
•Discharging is performed within specied
temperature limits (-10oC to +45oC / +14oF to
+113oF), only to a dened voltage limit, with a
current dened from the needs of the load. The
limits for Voltage, Temperature and Current are
set in the BMS without the intervention of the
user.
Each Li.ONESS system is designed to meet the
power and energy requirements for a specic
application.
•The battery’s operational limits are fully
controlled from the BMS which consists of three
types of electronic boards (the MAB, the CMU
and the secondary safety boards), contactors and
switches.
The BMS protects the battery from the following
dangerous failure modes:
•Over - Under voltage
•Over - charge / discharge
•Over - Under temperature
•Over - current IN and OUT
MAB board is the central board and one is placed
at each battery. In this board all monitored
signals from the sensors mounted on the battery
(temperature sensors, shunt resistor) and the
signals from the CMU boards (cell voltages and
temperatures) are gathered.
MAB is responsible for:
i. The management of the auto power o (only for
EOL voltage limit)
ii. The communication with the Inverter/Charger
iii. The communication with the Li.ONESS battery
modules
iv. The communication with all the CAN BUS
attached devices
Furthermore, MAB has digital I/Os which can give
to BMS more functions such as heating, cooling
etc. in case it is required.
v. Connection to GLOCAL (Systems Sunlight Cloud
Platform), through GSM or Wi-Fi, to monitor the
performance and editing of the settings
(if it is needed / requested).
CMU boards monitor the cell voltage,
temperature, insulation resistance and they also
perform the cells’ balancing.
PBT boards are responsible to control the
contactor installed at each Li.ONESS module.
The PBT functionality gives the ability to
disconnect one or more parallel connected
Li.ONESS battery modules (in case of failure) from
the system without losing the complete Li.ONESS
system.
The disconnection of a parallel module can be
performed manually via the BMS tool or remotely
by Systems Sunlight or by the customer via the
cloud.
Example
If there is a faulty Li.ONESS battery module (i.e.
communication error, low performance cell,
etc.) the system will raise an alarm on Systems
Sunlight’s cloud platform (GLOCAL). E-mail
notication will be sent directly to Systems
EN

Li.ONESS Batteries | Operation, Safety and Installation Manual
20
Sunlight S.A. and the customer.
At this stage, the user/distributor can deactivate
the Li.ONESS battery module manually via the
cloud (or the BMS tool) without the need of
a site visit. No other hardware modication /
disconnection should be made.
The faulty module can be totally disconnected
remotely, allowing the Li.ONESS system to
continue operating with reduced capacity.
The hardware disconnection of the faulty module
can be done on a later stage of normal operation
of the battery.
Replacement of the faulty module with an
operational one (or the same repaired) can be
done following the steps above (chapter 5).
7.3 Control Panel Operation
There is one control panel located at the Power
Unit (P.U) / PBT Unit (where applicable) of the
Li.ONESS system.
The control panel (pic. 29) has ve (5) green LEDs
which are used to show the SoC of the Li.ONESS
system in normal operation. It also informs the
user for the error messages which are displayed
by ashing certain LEDs depending on the type
of error (see Table 2). It has, also, an Error LED
(!) which in case of error message, turns red and
nally an ON/OFF button.
ON / OFF button: When the battery is active
(ON) and in standby mode, press the ON / OFF
switch to turn OFF the battery. When the battery
is in operation (charging or discharging) and the
current >10A (charge) or <-10A(discharge) the
battery cannot be turned o by pressing only the
ON /OFF button.
Alarms displaying: On the control panel, there
are shown the errors and warnings that could
possibly occur to the Li.ONESS system battery
during the operation. The ashing speed and the
combinations of the LEDs is dening the occurred
alarm.
The sequence of the ashing speed of the LEDs is
