12�5 External power meter
External power meters can be connected to every Solar-Log™ model via the S0 input and/or the RS-485
bus.
Solar-Log™ devices have a varying number of SO inputs:
S0 inputs
Solar-Log™ Number of S0 inputs
Solar-Log™
300*, 1200 and 2000 2 - S0
A
and S0
B
* Solar-Log 200s prior to 2011 do not have an S0 input
The energy recorded by these meters can be used for numerous applications:
•
Inverter mode
This mode is used for inverters that are not directly supported by Solar-Log™.
•
Total yield meter
This mode is used to record the energy production of several inverters.
•
Consumption meter
This mode is used to measure power consumption and to make it possible to display this data and
to use Smart Energy functions.
•
Utility Meter (U) (only Solar-Log 1000, 2000)
This mode is used for voltage measurements for reactive power control with the characteristic
curve Q(U).
•
Utility Meter (U+I) (only Solar-Log 2000)
This mode is used to record the measurement data needed for the response signals sent to the grid
operator and for cos phi control at the feeding point.
Note
We recommend using the meters that we have tested and offer.
We cannot guarantee the functionality of other products.
Note
Consumption meters can be assigned to plant groups.
It is only possible to assign a meter after a rule with the calculation of self-consumption
has been activated in the power management configuration Configuration | Special
Functions | Feed-in Management .
