1. A method of communication of distributed devices handling electric energy with communication partners via the internet, the method comprising:
providing a server; programming rules in the server, the rules determining between which at least one device and which at least one communication partner a communication connection is to be mediated based on generic properties of the devices, generic properties of the communication partners and an initializing time-variable datum, the communication connection being selected from a group of connections consisting of point to point, point to multi point and multi point to multi point connections via the internet; transmitting data from each device to the server via the internet, the data including both a communication address and attributes indicative of the generic properties of the device; transmitting further data from each communication partner to the server via the internet, the further data including both a communication address and attributes indicative of the generic properties of the communication partner; and mediating the communication connection between the at least one device and the at least one communication partner determined by the rules in response to a value of the initializing time-variable datum also defined by the rules; and transmitting at least one data transfer request from the at least one communication partner to the at least one device and at least one requested datum from the at least one device to the at least one communication partner via the communication connection, or transmitting at least one command from the at least one communication partner to the at least one device and at least one command confirmation from the at least one device to the at least one communication partner via the communication connection; wherein the devices handling electric energy are inverters being part of at least one photovoltaic power plant or controllers of such inverters, wherein the communication partners are selected from a group of partners including at least one of the devices, surveying computers for the devices, monitoring computers for the devices, service computers for the devices, mobile terminals and data loggers, wherein the generic properties of the devices and the generic properties of the communication partners are selected from a group of properties comprising their type, their firmware, a state of their firmware, their design, their construction, their operation state, their dimensions, their owner, their operator, a name of a superordinated system, their grid connection area and their spatial position area. |
