Status Message
Description
Disconnected
Indicates that a communication problem exists between the display and
the inverter. Check for bad cable connection.
OV Power Limit
The inverter has detected that the output voltage is approaching the
over voltage limit and is reducing its output to compensate for the less
than ideal current carrying ability of grid connection.
The Up and Down arrow that is visible on the left side of the touch screen display is used to scroll through
a list of parameters. The list of viewable parameters is as follows:
Parameter
Description
Grid Voltage
Magnitude of the connected single phase grid voltage
Grid Frequency
Frequency of the connected single phase grid voltage
Bus Voltage
Magnitude of the DC link bus voltage
DC Current
Averaged value of the DC current
Turbine Volts
Averaged value of the rectified DC voltage from the Input
Output Power
Output power displayed in Watts
Accumulated
Energy
Output Energy (kW hours) accumulated over time of operation
VREF
Used for factory/installer setup
IREF
Used for factory/installer setup
Last Fault
Displays the last fault that occurred since the inverter was powered up along
with a fault code that may be useful when troubleshooting.
Unit Code Rev
Indicates the firmware revision of the control DSP
Disp Code Rev
Indicates the firmware revision of the LCD display DSP
A hidden feature of the display is the contrast adjustment. The right side of the display has invisible up
and down arrows that can be used to increase and decrease the contrast of the display.
Grid Voltage
This the voltage measured line to line on the output of the inverter. The voltage must be between 212 to
264Vac (184 to 228Vac for 208V units) for the inverter to operate. The line to neutral voltage is important
as well, although it is not reported on the LCD screen. It must be between 106 and 142Vac for both 240V
and 208V units.
Grid Frequency
This is the frequency of the grid and determined by the utility. The frequency must be between 59.4 and
60.4 Hz for the inverter to operate.
Bus Voltage
This is the voltage of the boosted DC link bus that is used to generate the output sine wave. This voltage
should stay between 200 and 570 Vdc but will not trip off until it reaches 680Vdc.
