Description
technical field [0001] The invention relates to the field of energy storage, in particular to a household energy storage converter and a control method for the household energy storage converter. Background technique [0002] The household energy storage converter is a device used in the indoor environment of the home. It controls the charging and discharging process of the energy storage battery, performs AC-DC conversion, and can directly supply power to AC loads without a grid. The household energy storage converter is composed of a DC-AC bidirectional converter, a control module and other modules. The controller of the household energy storage converter receives the background control command through the communication unit, and controls the converter to charge or discharge the battery according to the sign and size of the power command, so as to realize the adjustment of the active power and reactive power of the grid. The household energy storage converter communicates...
