4. Features
The Lithium Series Slim 48V 2.4 kWh battery has the following features:
•Designed for use in photovoltaic applications.
•Battery Management System (BMS): The BMS system built into the battery that monitors its
operation and does not allow it to work outside the bounds of the design regime (V, I).
•Expandability: The system's accumulation capacity can be expanded by incorporating more
batteries.

5.3. Assembly and connection
Batteries may be connected in parallel up to a maximum of 15. All batteries must be grounded. It is
suggested to connect the installation ground to the rack at the same point as all battery lands.
•Connection between batteries:
-Up to 15 batteries are allowed to be used in parallel.
-The batteries used in parallel must be the same batch of cases with the same SOC.
-The Voltage difference of batteries used in parallel must be within 0,5V.
-The dimensions of parallel cable must be the same.
-The batteries must be connected two by two with the same cable to the bus,
following next scheme.

•Connection between battery and inverter:
25 mm2 power cable section.
NOTE: Each power cord can carry a maximum of 120 A, so every two batteries would need to
connect a new cable to the inverter. However, if the inverter is 5 kW only with one cable it
would be enough to be at the limit of the maximum current recommended.

Warning when doing a battery expansion: It is very important that in the case of connecting
batteries in parallel that are not new (for example, we add a new battery to an existing system), we
previously perform a voltage balancing (without load) between them to avoid overcurrents that
could damage the system. As an alternative to balancing voltages, balancing can be done by equalizing
the SOC of the batteries. In addition, when connecting new batteries, we must take into account that
the number of batteries at the time of connection must be similar to the number of batteries that are
already connected in the system. For example, if we have five batteries installed and we want to
connect a new one, we must first connect the new battery with two of the five that were already in
place to balance them, and then connect these three with the other three remaining batteries in the
system. Batteries should always be connected in groups of similar numbers so that a large group
cannot damage a smaller group of batteries at the time of connection.
5.3.1. Configuration without communications
For those cases where the battery is intended to operate connected to an inverter without
communications, it’s not necessary to select a specific configuration of the DIP switches and the
batteries do not need to be connected each other with the communication cable.
5.3.2. Configuration with communications
Communication cable: It will be configured one way or another depending on the inverter used.
Cable configuration Hybrid Inverter Turbo Energy/
Goodwe/Solis/Growatt
· It can be used a Straight-through cable
· Connect the cable to the CAN-2 port
· Growatt inverter is connected to the
RS485-3 port
