• DIP Switches – Parallel DIP switch definition: For multi-battery communication when the battery packs are connected in parallel, use the DIP switch to distinguish the different battery pack addresses; the battery address can be set by the DIP switch on the panel below.

Dimensions

Capacity Options
The battery can be connected in parallel for increasing power(kW) and energy(kWh).
WARNING

• The maximum power (kW) is limited by the main cables from master battery to inverter.
• Maximum number of batteries that can communicate in parallel is 8.
  FOR EXAMPLE – One Pack is 2.56kWh

Parallel Communication

When multiple battery packs are connected in parallel, the RS485 interface is used as the parallel communication interface. The master battery can manage all of the paralleled slave batteries through the RS485 communication. Two batteries RS485 parallel connection 1:

• More than two batteries RS485 parallel connection 2:

Recommended Settings
Lithium batteries function differently to lead-acid batteries, therefore the device in which you connect to the battery for charging and discharging, such as aninverter, MPPT charger controller or UPS should implement the recommended settings below.

ATTENTION

• Before using the battery pack, please read the manual carefully to understand the usage and precautions;
• Non-professionals shall not disassemble the battery without authorisation;
• During usage or storage, if you notice any abnormal temperature, discoloration, deformation or other abnormalities in the battery, please stop using the battery;
• The working temperature of the battery is -10~55°C;
• The storage temperature of the battery is -10~35°C. Please place the battery in a dry and cool environment
• If the battery is not to be used for a long period, the battery pack needs to be charged to more than 80%, turn off the power switch, and store it in a ventilated and dry environment.
