2. Product description
2.1 Product Overview
ESS R050096 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
The battery system is based on a lithium iron phosphate battery and adopts a modular parallel
design lithium battery system.
◼
Mainly consists of one cabinet and multiple battery modules.
◼
The nominal capacity of the battery is 2.4kWh, and the nominal voltage of the battery is 48V.
◼
The single cabinet supports up to four 48V/50Ah battery modules in parallel.
◼
Supports up to two cabinets in parallel and can be expanded to 19.2KWh.
◼
Customized battery management system (BMS), real-time data acquisition, status monitoring
and control to ensure safe and reliable operation of the system.
The system has flexible configuration and high reliability, which can be widely applied to
household energy storage scenarios.
