A37: AC Curr
Over Rating
A42: CT Current
Sensor Fail
Detection circuit malfunction
1.Inverter choke Fail
2.Output Filter Fail
3. Detection circuit malfunction
Check the detect circuit inside the
inverter
A35: Bus Volt
Over Rating
1. Driver for boost is defective
2. Voc of PV array is over
600Vdc (RPI-H3) or
1000Vdc (RPI-H5)
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
600Vdc (RPI-H3) or
1000Vdc (RPI-H5)
3. N/A
4. Check the detection circuit inside
the inverter
1. Check Inverter choke inductance.
2. Check output filter capacitance.
3. Check the detection circuit inside
the inverter
