In this example the elgris BASIC is used as the master controller. The BASIC communicates with each
generator over Ethernet and collects the load of each generator. The BASIC controller automatically
determines the optimum setpoint for each generator and sends a setpoint to the PV inverters.
When the grid is connected to the load, the grid setpoint is used.
In case that the PV energy available is higher than the possible load for the whole system, an optional
storage can be charged and discharged later.
