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
• 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 DC
Voltage
Test – DC switch OFF
• Check DC at the inverter test points
• If DC Voltage is high, check string configuration
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
DC Voltage on internal bus
Test
• Measure DC and AC voltages
• Compare with LCD
• Replace Inverter
• Internal damage
