Household intelligent control energy storage power supply is a smart fixed energy storage device tailored for residential daily power management, integrating energy storage, intelligent monitoring, and automatic power switching functions. Equipped with an intelligent management system, it can real-time monitor household power consumption, battery remaining power, and grid power supply status, and realize automatic switching between grid-connected power consumption and battery power supply. Users can remotely view and control the equipment through mobile APPs, adjust power supply priority, and set charging and discharging time. With a capacity of 5–20kWh and support for whole-house low and medium-power load operation, it is mainly used for daily peak-valley electricity price adjustment and short-term household power outage emergency power supply, bringing intelligent and energy-saving power consumption experience for families.

Grid-connected voltage-stabilizing energy storage equipment is a professional power-supporting energy storage device oriented to grid-connected operation scenarios, suitable for families and small commercial places with unstable grid voltage. Its core function is to stabilize grid voltage and frequency, solve common power problems such as grid voltage fluctuation, instantaneous power failure, and voltage surge in residential areas. When the grid voltage is too high or too low, the equipment will automatically absorb or release electric energy to maintain voltage stability within the standard range, protecting household electrical equipment from damage caused by voltage abnormalities. In addition, it can store grid surplus power and feed back redundant electric energy to the grid, realizing grid peak shaving and valley filling, with higher grid compatibility and power stabilization performance than ordinary household intelligent energy storage.

Photovoltaic off-grid energy storage kits are integrated power generation and energy storage systems composed of photovoltaic panels, energy storage batteries, inverters, and intelligent controllers, specially designed for completely off-grid power consumption scenarios. Different from grid-connected equipment, this kit does not rely on municipal power grids and independently completes the whole process of solar power generation, electric energy storage, and power output. The photovoltaic panels convert solar energy into electric energy during the day, and the energy storage module stores redundant electric energy to support power consumption at night or in rainy days with insufficient light. The kit has flexible configuration, supporting capacity and power customization according to household power demand and roof installation area.

These three types of equipment have clear differentiated positioning in household scenarios. Household intelligent control energy storage focuses on intelligent daily power management and emergency power supply; grid-connected voltage-stabilizing energy storage focuses on grid power quality optimization and voltage stabilization; photovoltaic off-grid energy storage kits focus on self-sufficient off-grid power supply, which is the best choice for remote families without grid coverage or families pursuing clean energy self-use.
