Accessing Diagnostic values
Current power output (kW):
The value refers to the current output generated by the inverter per interface (column) and for the entire
plant.
Control value power (% AC):
The Solar-Log™ calculates the control value power (kW) as a percentage of the maximum AC power and
relays this to the inverters.
Current power output (AC%):
The value indicates the total output generated as a percentage of the maximum AC power for the inverter
or all of the inverters on a bus.
Feed-in power (% DC):
This value is the current amount of feed-in power as a percentage of the generated output.
17.5.2 Explanation of the Symbols in the Feed-in power (% DC) column:
The feed-in power value is in the target power range with a tolerance of -2% to +1%.
The feed-in power value is below the target value allowed. Generally, this means that the out-
put allowed at the grid connection point is not being achieved due to low irradiation or high
self-consumption.
This means that the value is above the target value allowed.
If the red triangle is only displayed at a bus and entire plant has a green symbol, this means
that only this bus is over the target value allowed. However, the plant totals do not go over the
target value because of self-consumption.
