2.Product introduction
2.1 Product introduction
Function
Li-ion battery includes only battery modules, which can store
and release electric energy according to the requirements of inverter management
system. The input and output ports of battery are 48 / 51.2V DC.
◆ Battery charging: the power control module is connected with the energy storage
terminals (BAT +, bat -) of the inverter to charge the battery and store the excess
photovoltaic energy in the battery under the control of the inverter.
◆ Battery discharge: when the photovoltaic energy is insufficient to supply power to the
load, the system needs to control the battery to supply power to the load and output
the stored battery energy to the load through the inverter.

◆ The inverter only needs to communicate with the host (Pack1).
◆ When multiple batteries are connected with multiple inverters, it is best to connect
through the combiner box. If it is not connected through the combiner box, the
wiring mode shall be confirmed with the manufacturer's agent. And the cable from
each battery to the inverter remains the same length.
◆ Batteries are not allowed to be connected in series.
◆ Different batteries with different chemistries, different batches of batteries from the
same chemistry and technical design parameters can not be bundled and used
together.
