Error
Message
F60: IOCP(PV1)
1. Switching device in boost is
defective
2. Driver for boost is defective
3. Input current detection circuit
malfunction
F61: IOCP(PV2)
F62: IOCP(PV3)
F63: IOCP(PV4)
F77:
CT sensor Fail
1. Inverter choke Fail
2. Output Filter Fail
3. Detection circuit malfunction
1. Check Inverter choke inductance.
2. Check output filter capacitance.
3. Check the detection circuit inside
the inverter
Possible cause Action
1. Check all switching device in boost
2. Check the driver circuit for boost
inside the inverter
3. Check input current detection circuit
F36: Inverter
OCP HW
1. Driver for inverter is defective
2. Detection circuit malfunction
F48:
Over Load
(Standalone)
Load power exceed rating power Check load power, remove load.
F57:
Aux-Power Fail
1. Auxiliary power circuitry malfunction
2. DSP ADC sample malfunction
1. Check the auxiliary power circuit
nside the inverter
2. Check sampling circuit inside the inverter
F50: PLL Fail
1. The DC component in grid
voltage is too large.
2. Incorrect country or Grid setting
1. Measure DC component of grid
voltage, using multi meter
2. check if Check country & Grid setting
F35: Bus Over
Voltage HW
1. Driver for boost is defective
2. Voc of PV array is over 550Vdc
3. Surge occurs during operation
4. Detection circuit malfunction
1. Check the driver circuit for boost
inside the inverter
2. Modify the solar array setting, and
make the Voc less than 540Vdc
3. N/A
4. Check the detection circuit inside
the inverter
