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.
