n
Each characteristic curve is defined by 2 to 8 nodes.
n
A node is defined by the output power P of the inverter (x-axis) and the
associated phase shift (y-axis).
n
The phase shift can be set over a range of 0.95 (overexcitation) through
1.00 (no phase shift) to 0.95 (underexcitation).
n
The type of phase shift is shown in the graph using arrow symbols
defined as follows (defined from the point of view of the inverter):
Overexcitation, inductive
Underexcitation, capacitive
n
The 3 characteristic curves available for selection have the following
properties:
Default char. curve
: pre-defined according to the selected
country (example in Fig. left).
Char. curve φ = 1
: pre-defined with cos φ = constantly 1.00. This
characteristic curve must be selected if no reactive power control is to
be performed on the device.
Enter char. curve
: The number of nodes and their x/y values can
be configured. Exceptions: The first node is always at x (P %) = 0 %,
the last always at x (P %) = 100 %.
Service technicians can use this menu item for changing additional MSD
parameters.
3.4 Cooling
The internal temperature control system prevents excessive operating tem‐
peratures. When the internal temperature is too high, the inverter adjusts
the power consumption from the PV generators to reduce the heat dissipa‐
tion and operating temperature.
The inverter is convection cooled via fins on the front and rear side. A
maintenance-free fan circulates the heat within the closed housing evenly
over the entire surface of the housing.
3.5 Grid monitoring
The inverter constantly monitors the mains grid parameters while feeding
the grid. If the grid deviates from the legally prescribed specifications then
the inverter automatically switches off. When the grid conforms to the
legally prescribed specifications then the inverter automatically switches
on again.
