Abstract: A home energy control system and a controlling method thereof are provided. The system comprises: an energy storage unit (101) configured to store energy, a grid-connected inverter (102) connected with the energy storage unit (101) and configured to transmit power from the energy storage unit (101) to a power grid (120) and/or transmit power from the power grid (120) to the energy storage unit (101), an off-grid inverter (104) configured to transmit power from the energy storage unit (101) to household devices (130), a new energy generating unit (103) configured to generate power domestically to charge the energy storage unit (101) and a controller (105) connected with the energy storage unit (101), the grid-connected inverter (102), the new energy generating unit (103) and the off-grid inverter (104) respectively and configured to control the energy storage unit (101), the grid-connected inverter (102), the off-grid inverter (104) and the new energy generating unit (103) to run in a gird-connected mode, an off-grid inverter mode and/or a new energy generating mode. The method comprises the step of controlling the system to run in at least one of the following modes after mode conflict check: the new energy generating mode, the grid-connected inverter mode and the off-grid inverter mode.
