The invention discloses a photovoltaic energy storage microgrid system, which comprises a control module, an energy storage module, a current converter and a photovoltaic module, wherein the control module judges electricity utilization time periods; at the first electricity utilization time period, the control module controls the energy storage module to supply power to a load by means of the current converter when electric quantity of the energy storage module is sufficient, and controls the energy storage module to stop supplying power to the load when electric quantity of the energy storage module is insufficient; and at the second electricity utilization time period, the control module controls the current converter to charge the energy storage module by utilizing a power grid. Electric energy generated by the photovoltaic module is input into the power grid and/or supplied to the load, thus the user benefit can be maximized; at the first electricity utilization time period, the control module controls the energy storage module to supply power to the load at first, and then the photovoltaic module and/or the power grid can supply power to the load when electric quantity of the energy storage module is insufficient; and at the second electricity utilization time period, the control module utilizes the power grid for charging the energy storage module, so that electric quantity of the energy storage module can be supplemented. The invention further discloses a control method of the photovoltaic energy storage microgrid system.
