2. Product description
2.1 Product overview
ESS R050100 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 are 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.
2.1.1 Battery
ESS R050100 Battery Cabinet components are defined as below:
◼
Battery module H102025M-S: The Battery module provides the energy and sends the
information about the cell voltage and cell temperature in the battery module to the upper
layer BMU. The nominal capacity of the battery is 2.5kWh, and the open circuit voltage of the
battery is 102 ~ 106V.
◼
Battery control boxH100030H-P01: Two parts consisting of both the battery management and
control component mounted on top of the battery modules as well as structural base, which
physically supports the battery modules underneath. The top portion of the BCMU is
responsible for communication to and connection with the inverter or BMU.
ESS R050100 battery cabinet consists of 4 battery modules (H102025M-S) and battery control
box (H100030H-P01). The system voltage and total capacity can be configured according to different
application scenarios and requirements.
