The photovoltaic system (1) comprises a photovoltaic module (2), an inverter, a control unit (4), a power meter (8), and an electrically rechargeable battery pack. The system is designed to supply a first electrical load and/or a public electricity network (6). The control unit is executed for regulating the electrical load consumed from the first electrical power. The power meter is executed to measure the electricity network delivered electric power and an electricity network-related electrical performance. A first connection of the power meter is provided with the control unit. The photovoltaic system (1) comprises a photovoltaic module (2), an inverter, a control unit (4), a power meter (8), and an electrically rechargeable battery pack. The system is designed to supply a first electrical load and/or a public electricity network (6). The control unit is executed for regulating the electrical load consumed from the first electrical power. The power meter is executed to measure the electricity network delivered electric power and an electricity network-related electrical performance. A first connection of the power meter is provided with the control unit for transmission of the power output to the electricity network, and a second connection of the control unit is provided with the first electrical load for controlling the power consumption of the first electrical load. The first electrical load is a heat pump, an electric heating element and/or an electric charger. The control unit is connected with a second electrical load such as an electric immersion heater, an electrical charging station and/or an electrically rechargeable battery to utilize a surplus power. The electrically rechargeable battery pack is controllable by the control unit and is provided with a battery monitor for detecting the charge state of the battery pack. The battery pack comprises a power inverter controllable by the control unit for delivering electrical output power to an electrical power household. The battery monitor is executed for receiving electrical power from a photovoltaic module and charging the battery pack. Independent claims are included for: (1) a control unit for a photovoltaic system; and (2) a method for controlling an electric power of a photovoltaic system emitted at a first electrical load and a public electricity network. |
