2.1. Intended Use
The battery system is for residential and works with a
photovoltaic system. It is a high voltage Li-ion battery
storage system, with the control unit on itself. It could
be operated in on-grid, off-grid and backup modes with
compatible inverters.
The battery system could be connected to the Internet
through network cable for maintenance and rmware
updating.
The battery system must only be used as stationary
equipment.
The battery system is suitable for indoor and outdoor use
under the conditions mentioned in Section 5.1.
The battery system is not suitable for supplying life-
sustaining medical devices. Please ensure that no
