2.1 Product Overview
SunBeat series home energy storage system products are composed of lithium batteries and bidirectional energy
storage inverters (hereinafter referred to as PCS), providing renewable energy applications and uninterruptible power
supply support services. The system can be used in scenarios where photovoltaics is used spontaneously and the
excess is connected to the Internet: during the day, photovoltaic power generation first meets the power demand of
the load, and the excess electricity charges the battery or the grid; when there is no photovoltaic at night, the load
can choose to use the grid or battery power supply.
