Technical details of solar generator Peter Nissen

All generators work independant from each other and feed the electrical energy totally into the public power system.
Data of the generators were transmitted to a SMA Sunny Boy Control for data logging by power line communication (Sampling rate 5 minutes) until March 20, 2008.
NEW: One electronic totalizer (type FINDER FIN 7E) is installed for each power inverter. Pulses of the S0 interface (1000 pulses/kWh) are counted by an embedded computer sytem NetDCU3 supplied by F&S Elektronik Systeme. This Linux computer uploads the energy results at a rate of 5 minutes.
Overall result is a real time display of solar energy.
