Fixed voltage
Using the inverter for fixed voltage operation is not considered an intended use. If, never-
theless, the inverter shall be used for fixed voltage operation, consultation with Steca is re-
quired.
NOTE
The PV generator must be suitable for feeding in a fixed voltage.
Fixed input voltages in the inverter may damage unsuitable PV generators or
reduce their yield.
►
The parameter for fixed voltage are password-protected. The specialist
can only change these parameters after consultation with Steca.
The device can adjust the input voltage to a manually configu-
rable value. Thereby, the automatic setting of the MPP (MPP
tracking) is switched off.
The entered parameter value may lie between the maximum
and minimum input voltage in 1 V increments.
A possible example for application of fixed voltage operation
are hydropower plants.
PowerPeak Scan
With the PowerPeak scan, the energy yield of the inverter can
be improved in the case of partial shadowing of PV strings (e.g.
by parts of buildings, trees or power lines). The current MPP is
intentionally left for a short time to hereby find the better MPP.
The scan is only performed approx. every 10 minutes to impair
the total energy yield caused by the brief power reduction dur-
ing the scan process as little as possible.
The PowerPeak scan can be switched off in "Settings" >
"Service" > "PowerPeak Scan".
