The high-voltage wall-mounted household energy storage system is the core equipment for household energy management in the era of new energy. With its wall-mounted design as the advantage for space adaptation and high-voltage technology as the performance support, it becomes the key carrier for the autonomy of residential energy. This system is usually composed of lithium iron phosphate battery packs, high-voltage inverters, battery management system (BMS), and intelligent control modules. The voltage is generally above 200V, featuring high energy density, rapid charging and discharging, remote monitoring, and multiple safety protections (such as over-temperature and over-current protection). Typical product parameters cover capacities of 5-20 kWh, more than 6000 cycle lifetimes, 5-10kW discharge power, and support CAN/RS485 communication protocols and compatibility with multiple brands of inverters. It can flexibly adapt to residential scenarios such as electric vehicle charging, self-generation and self-consumption of photovoltaic power, and optimization of peak-valley electricity prices, especially suitable for living environments with limited space such as apartments and small houses, perfectly solving the pain point of large占地面积 of traditional ground-based energy storage systems.
