1.1 Recording Energy Flows with External Power Meters
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, 1900 and 2000 2 x S0-In and 1 x S0-Out
Solar-Log
1000, 500
1 x S0-In/Out
Solar-Log
200
1 x S0-In
Solar-Log 250 1 x S0-In
Note
The Solar-Log™ requires a S0 pulse duration of 30-40 ms. That is why we recommend using
SDS tested meters that we offer.
We cannot guarantee the functionality of other products.
In addition, the maximum length between the power meters and Solar-Log™ should not exceed
10 m.
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 | Feed-in Management .
External power meters/accumulating meters
With multiple phase meters, a basic distinction is made between phase-exact and accumulating meters.
Accumulating meters provide the total values from all three phases. The meter calculates the total output (to and
from the grid) of the individual phases and provides this total as a single value.
In the example:
Phase 1 supplies 3 kW via an inverter (single phase).
Phase 2 refers to 2 kW (energy).
Phase 3 refers to 1 kW (energy).
With an accumulating meter, this results in a total of 0 kW.
An example of an accumulating meter is the Janitza UMG 104 or the Solar-Log™ Pro380 Mod.
