Alarms

Cause

Solution

•  Inverter detects grid 

  Frequency as too high

OV-G-F: Over 

Grid Frequency

  

Test – DC switch OFF

•  Check frequency at the inverter test points

•  If Frequency measures high, adjust upper 

  limit with permission from utility

•  Check LCD reading, may be a bad 

  measurement circuit

  

Test – DC Switch ON

•  Check grid standard

•  Replace inverter

NO-GRID

•  Inverter does not 

  detect the grid

  

Test – DC switch OFF

•  Check AC at the inverter test points

•  L-L, L-GND

•  Do NOT tell me 240VAC

•  Check LCD reading, may be a bad 

  measurement circuit

  

Test – DC Switch ON

•  Check grid standard

•  Replace inverter

OV-DC: DC 

voltage is too 

high

•  Inverter detects High DCV

  

Test – DC switch OFF

•  Check DC at the inverter test points

•  If DCV is high, too many panels in the string

  

Test – DC Switch ON

•  Check LCD reading, may be a bad 

  measurement circuit

•  Replace inverter

OV-BUS: DC 

BUS voltage is 

too high

•  Inverter detects High 

  DCV on internal bus

  

Test 

•  Measure DC and AC voltages

•  Compare with LCD

•  Replace Inverter

•  Internal damage

•  Wire came loose during shipping

UN-BUS: DC 

BUS voltage is 

too low

•  Inverter detects low DCV 

  on internal bus

 

  

Test 

•  Measure DC and AC voltages

•  Compare with LCD

•  Replace Inverter

•  Internal damage

•  Wire came loose during shipping

Alarms

Cause

Solution

•  Inverter detects grid 

  instability, internal fault 

  current high

GRID-INTF: 

Grid unstable

  

Test – With DC Switch OFF

•  Measure AC voltage

•  Test AC line for THD

•  Test – With DC Switch ON

  

Test AC line for THD

•  Multiple inverters/turn one off

•  Impedance matching adjustment or box

•  Internal damage

•  Wire came loose in shipping

•  Master and Slave DSP 

  have different values

  

Reset Inverter

•  DC switch OFF

•  Wait until all lights/LCD turn off

•  DC switch ON

•  Replace inverter

•  Inverter detects high 

  ambient temperature >60C

  

Inspect installation

•  Check heatsink for obstructions/ventilation

•  Is inverter in direct sunshine

•  Measure ambient temperature near inverter

•  If temp is in range replace inverter

•  Inverter detects low DC 

  insulation resistance

  

Inspect installation

•  Reset inverter

•  Note weather conditions when alarm occurs

•  Measure insulation resistance

•  If normal, measure in SAME weather as alarm

•  Physically check cables

•  Replace inverter
