USERS MANUAL WINDMASTER 500
Power Curve
The Windmaster 500 converts DC power from a
wind turbine to the AC grid based. This conversion
is based upon a linear curve with a start voltage
and a maximum operating voltage (see figure 1).
These parameters may be adjusted and optimized
by the system vendor for use with a particular wind
turbine. When DC voltage reaches the threshold
voltage to start up the Windmaster, the inverter
starts a 5 seconds countdown before delivering
energy to the AC grid.

Example installation diagram
See figure 2. This drawing is not specific for any
wind turbine or installation. It is provided as a basic
reference, showing necessary major components
and installation sequence. Please contact your
system vendor for detailed installation drawings,
specific for you wind turbine.
DC interface
The DC interface is for protection of the
Windmaster 500, and should provide the following:
• Surge protection (if applicable);
• Over voltage protection, max. 150VDC (*);
• Disconnection switch (if applicable).
(*) Mechanical either electrical OVP may be
integrated in the wind turbine
Grounding
The Windmaster 500 is a class II device with
galvanic isolation between DC and AC. The
inverter doesn't need to be grounded. Grounding of
the Wind turbine however is recommended.
Paralleling
Multiple Windmasters 500 can be operated in
parallel to increase output power. The DC side of
each Windmaster 500 must be protected by a 10A
(slow blow) fuse (refer to figure 2).
