Error
Message
E28: UVR-Slow
E30: OVR(PV)
E34: Insulation
1. Actual utility voltage is under the
UVR setting
2. Incorrect country or Grid setting
3. Detection circuit malfunction
1. Actual Solar voltage is over
560Vdc
2. Detection circuit malfunction
1. PV array insulation fault
2. Large PV array capacitance
between Plus to Ground or Minus
to Ground or both.
3. Detection circuit malfunction
1. Check the utility voltage on the
inverter terminal
2. Check country & Grid setting
3. Check the detection circuit inside
the inverter
1. Modify the solar array configuration
and make the Voc less than
550Vdc
2. Check the detection circuit inside
the inverter
1. Check the insulation of Solar inputs
2. Check the capacitance, dry PV
panel if necessary
3. Check the detection circuit inside
the inverter
