INPHESS-518/500-0.4 is a 500kW 10ft Container for Energy Storage System, supporting two independent PV inputs (INPMPPT-62.5 module×2), one rated 250kW diesel generator or grid AC input (INPPCS-125 module×2), and one rated 500kW AC output (INPPCS-125 module×4) with a continuous maximum output of 550kW.
On the DC side, it adopts LFP LiFePO₄ cells with air/liquid cooling technology, maintaining a cell temperature differential of less than 3℃ to enhance efficiency and extend lifespan.
On the AC side, it consists of DCDC+ACDC+DCAC modules equipped with advanced SiC devices to improve operational efficiency, complemented by an optional isolation transformer to meet high power quality requirements. The containerized energy storage system’s key internal components include a self-powered UPS which uses its own batteries for low-power long-term standby in off-grid mode and black start capability.

PRODUCT FEATURES
01
High efficiency: PCS utilize SiC devices and high-permeability metal powder core inductors, achieving superior efficiency across all operating ranges compared to IGBT-based and conventional inductor modules, with peak efficiency reaching 99%.
02
Wide voltage range: Photovoltaic MPPT module supports a wide voltage range; BESS AC side accepts three-phase four-wire connections, supporting 400Vac 50/60Hz, with the option to reduce isolation transformers for handling unbalanced loads.
03
Long standby: 1000Vdc to 24Vdc is used to supply power to key components of the system such as BMS and EMS, reducing the standby power consumption of the whole system, freeing itself from the limitation of short power supply time by UPS alone, and ensuring ultra-long standby.
