Yield Monitoring
SP25-55_User Manual_B8_EN_2012-11-06 20/32
Parameter 224: SO-counter energy day
Menu: Actual values/Yield monitor
Unit: kWh
Resolution: 0,001kWh
This displays the "day yield", i.e. the yield on a particular 'today', measured by the external (S0) power
meter. This parameter can be used to display the day yield of a "neighbouring installation" or "external
installation" in an installation equipped with Solutronic inverters (e.g. for a large external display).
Parameter 225: SO-counter pulse today
Menu: Actual values/Yield monitor
Unit: ---
Resolution: 1
The number of S0 pulses measured 'today' is accurately recorded here.
14.4 Operating hours meter
The inverter uses the following parameters to display the number of operating hours:
Parameter 123: Operating hours today
Menu: Actual values/Yield monitor
Unit: h (Stunde)
Resolution: 0,1 h
Parameter 123 displays the length of time the inverter has already been switched on today.
The meter starts running as soon as the solar generator delivers an adequate voltage.
Parameter 124: Operating hours total
Menu: Actual values/Yield monitor
Unit: h (Stunde)
Resolution: 0,1 h
Default setting: ---
Password level: 4
Parameter 124 records and stores the total length of time the inverter has been switched on since it
was first started up.
14.5 Integrated yield monitoring
Each inverter is equipped with and capable of activating an integrated yield monitoring function. This
function is based on the comparison of yield data either from one inverter with an insolation sensor
connected or from an installation comprising at least 2 inverters that are networked by means of their
RS485 ports.
Details of how the yield monitoring function works can be found in the instructions for the master-slave
data network and in those for the sensor. Both manuals can be found on the CD supplied or can be
downloaded from www.solutronic.de. Your dealer can supply you with the activation code.
