10.2 Grid inverter
Your SkyWind NG micro wind turbine includes a high
-
end MPPT wind power grid inverter com-
puter. The inverter will control the turbines power output and rotor rpm several thousand
times per second to generate the highest possible energy yield. However, to perform its task as
efficient and safe as possible, the computer has to be set to fit your local conditions.
Brake / Dumpload
Your inverter connects with a dumpload to limit the rotational speed of your generator and not
having to use the storm control for every gust. The dumpload is included in your delivery and
will get hot while braking the rotor in gusts. Install the inverter and dumpload in a safe place
without fire hazard and connect the heating element to the
„
DUMPLOAD
“
contacts located on
the top cover of your inverter.
Multifunction LCD
-
display
Your inverter computer provides a coloured main LCD
-
display. Via this display and the buttons
next to it you can check for the turbines performance, grid and turbine voltages, current power
output and much more. To function correctly your inverter has to be programmed to your spe-
cific conditions.
The main menu
„
Power view
“
will display all key data of your system. If the display is showing a
„
Starting Voltage Too Low
“
message the wind speed is not sufficient for power generation
(below 22 V DC). The inverter will wait for the turbine to fully start
-
up before starting actual
power generation.
ATTENTION
The
„
Brake/Dumpload
“
function is an additional braking system and does NOT replace the au-
tomatic storm control. The turbine will always need an automatic storm control system!
