Manual Instruction
The Energy Storage Batteries System provides the energy storage for PV users and backup
power support for the important electrical equipment. The battery system can store excessive
power generated by PV system at daytime, and can utilize the stored energy (if necessary) to
supply power for electrical equipment at night, thus improving the utilization efficiency of
photovoltaic power generation, shaving peaks and filling valleys, providing backup power for
emergency and important electrical equipment to avoid data and financial loss caused by sudden
power outage.
The user manual introduces battery details like the basic structure, parameters, procedures
and methods of installation, operation and maintenance.
This manual is only for the 51.2V 100Ah Rack Mounted Lithium Battery, but the inverter
and any other equipment is not included.
This PRODUCT can be installed in parallel mode, more attention should be paid for the DIP
and address selection.
