LV-IESS-Hx_RH5.12x 50kWh Indoor rack-mounted installation

The LiTHIUMVALLEY LV-IESS-Hx_RH5.12x is a 50kWh indoor rack-mount energy storage system (1P series). It features a nominal energy capacity of 50kWh and a nominal voltage of 512V. It utilizes A+-grade lithium iron phosphate cells (3.2V, 100Ah), has a 15-year design life, and a cycle life of 26,000 cycles (@25°C, 0.5C-rate).

The system is equipped with a multi-level BMS for real-time monitoring and early warning, module-level heat absorption and fire extinguishing, and aerosol firefighting. It uses natural cooling with a fan and IP20 protection for indoor environments. It operates between 500V and 584V and has a maximum continuous charge and discharge current of 100A (25°C to 45°C).

Compatible with the “PYLON” protocol and mainstream high-voltage inverters, it supports multi-rack parallel connection. Available in two versions: LV-IESS-H4_RH5.12F (LCD display) and LV-IESS-H3_RH5.12F (indicator light), it is suitable for residential, commercial, industrial off-grid and emergency power supply scenarios.
