The invention provides a control method and device of a household energy storage system and the household energy storage system, and relates to the technical field of energy storage products. The method comprises the following steps: collecting the power supply state information of a power grid and the work indication information of a target household energy storage system; according to the power supply state information and the work indication information, working mode information of the target household energy storage system is selected, and the working mode information comprises grid-connected charging, grid-connected discharging and off-grid discharging; matching operation parameters of the target household energy storage system according to the working mode information; according to the operation parameters, a battery in the energy storage system is controlled to be charged and discharged, and when the voltage of the battery reaches a preset threshold value and the current is 0, charging and discharging are completed. According to the scheme, power can be supplied to the household load and the power grid in the off-grid state, DC fast charging of the electric vehicle is supported, the working mode switching is smooth, and the probability of user operation errors can be reduced through the preset operation parameters.
