No. Display Message Explanation
1
Display shown during the starting-up period (in the morning), after
a malfunction or prior to night shutdown. No grid feeding
in this
mode of operation. The inverter waits until the voltage has
exceeded a value of 125 V. If this value is exceeded for longer
than 4 minutes the grid feeding will be started. An audible sound
is generated when the grid isolation relay is enabled
2
Existing voltage and current of the solar generator connected to
the inverter. Shown in volts and amps; voltage tolerance ± 3 %;
current tolerance ± 5% at rated power. Greater tolerances are
possible when smaller generator currents are displayed.
3
Actual grid voltage, grid current and power (measurement of the
phase into which power is delivered); displayed in volts, amps
and watts; voltage tolerance: ± 3%; current tolerance: ± 3 %.
4
Short-team peak grid feeding capacity of the day,
displayed in W. According to the regulations stipulated by the
Power companies, this peak capacity must not exceed 10 % of
the rated power of the inverter. However, the generator may be
dimensioned for higher capacities.
5
Display of the actual heat sink temperature, in °C. The inverter
will limit grid feeding if the temperature exceeds 65°C. If the
device temperature exceeds 80°C it will switch off automatically.
6
Display of the various operating statuses
Normal grid-feeding operation. Power is fed into the grid.
Waiting for sufficient solar generator power. The generator
voltage is not sufficiently high for grid feeding, or the grid feeding
process was stopped and the system is re-started after a failure.
Waiting for night shutdown. The generator capacity is no longer
sufficient for grid feeding, and the device waits for the night
shutdown.
The device changes over to night shutdown.
