Embodiment Construction

[0024] figure 1 A block diagram of an inverter 1 is shown, which is supplied with direct current from a battery or other external energy source, such as a solar module 2 , and with alternating current, typically 230V, through a DC / AC module 3 . This alternating current is used to supply the various loads 4 , as is usual with stand-alone inverters, or in the case of a grid-connected inverter 1 , to be connected to the existing power grid 5 .

[0025] The inverter 1 includes a power supply unit 6 that supplies electrical energy to all components. In addition, a control device 7 is provided which may comprise various microprocessors 8 executing programs which may be used, for example, for flow control, operational control of error monitoring, battery status and / or solar modules 2 and and / or monitoring of menu navigation. Finally, an input / output device 9 can be provided, via which the different operating conditions of the inverter can be displayed or parameters can be entered. ...
