What to do if my Delta RPI M6A shows AC Cur. High (F36, F37, F38, F39, F40, F41)?
- M
  Madeline AndradeAug 25, 2025
  If your Delta Inverter displays the error AC Cur. High (F36, F37, F38, F39, F40, F41), it could be due to several reasons: * A surge during operation. * A defective driver circuit in the inverter stage – in this case, you should check the driver circuit in the inverter stage. * A defective switching device – in this case, you should check all switching devices in the inverter stage. * A detection circuit malfunction – in this case, you should check the detect circuit inside the inverter.

What does Solar1 High (E30) mean on my Delta RPI M6A?
- C
  carriephelpsAug 29, 2025
  If your Delta Inverter displays Solar1 High (E30), it could indicate that the actual Solar1 voltage is over 1000Vdc (in this case, modify the solar array setting, and make the Voc less than 1000Vdc) or a detection circuit malfunction (in this case, check the detection circuit inside the inverter).

What does it mean when my Delta Inverter displays Insulation (E34)?
- A
  abushAug 28, 2025
  If your Delta Inverter is showing the error Insulation (E34), it could be due to: * A PV array insulation fault. Check the insulation of Solar inputs. * Large PV array capacitance between Plus to Ground or Minus to Ground or both. Check the capacitance, dry PV panel if necessary. * A detection circuit malfunction. Check the detection circuit inside the inverter.

What does HW Con. Fail (E08) mean on my Delta RPI M6A?
- A
  Amanda WatsonAug 28, 2025
  If your Delta Inverter displays HW Con. Fail (E08), it could be due to: * Wrong connection in AC plug (in this case, check the AC connection, must accords to manual). * Detection circuit malfunction (in this case, check the detection circuit inside the inverter).

Why is my Delta RPI M6A showing AC Freq Low (E02)?
- C
  Christian BakerAug 27, 2025
  If your Delta Inverter shows AC Freq Low (E02), it might be because: * The actual utility frequency is under the UFR setting. Check the utility frequency on the inverter terminal. * The country or Grid setting is incorrect. Check country & Grid setting. * There is a detection circuit malfunction. Check the detection circuit inside the inverter.

Why is my Delta Inverter showing AC Freq High (E01)?
- J
  John HudsonAug 27, 2025
  If your Delta Inverter is displaying AC Freq High (E01), it might be caused by: * The actual utility frequency being over the OFR setting. Check the utility frequency on the inverter terminal. * An incorrect country setting. Check the country setting. * A detection circuit malfunction. Check the detection circuit inside the inverter.

What should I do if my Delta RPI M6A displays DC Cur. High (F60, F61, F70, F71)?
- B
  Brittney VasquezAug 27, 2025
  If your Delta Inverter displays DC Cur. High (F60, F61, F70, F71), the possible causes are: * A defective switching device in boost. Check all switching device in boost. * A defective driver for boost. Check the driver curcuit for boost inside the inverter. * Input current detection circuit malfunction. Check input current detection circuit.

What does it mean when my Delta Inverter displays AC Volt Low (E10, E15, E20)?
- D
  Debbie StewartAug 26, 2025
  If your Delta Inverter displays AC Volt Low (E10, E15, E20), it could be due to several reasons: * The actual utility voltage is under the UVR setting. In this case, check the utility voltage connection to the inverter terminal. * The country or Grid setting is incorrect. In this case, check the country & Grid setting. * There are wrong connections in the AC plug. In this case, check the connection in AC plug. * There is a detection circuit malfunction. In this case, check the detection circuit inside the inverter.

What does it mean when my Delta RPI M6A Inverter says No Grid (E09)?
- A
  Alexander SimonAug 26, 2025
  If your Delta Inverter shows a No Grid (E09) error, it could be due to: the AC breaker being OFF (in this case, switch on AC breaker) or a disconnection in the AC plug (in this case, check the connection in AC plug and make sure it connects to inverter).

What should I do if my Delta RPI M6A displays AC Volt High (E11, E13, E16, E18, E21, E23)?
- F
  fguerraAug 25, 2025
  If your Delta Inverter is showing AC Volt High (E11, E13, E16, E18, E21, E23), here's what you can check: * The utility voltage on the inverter terminal may be over the OVR setting. Check the utility voltage on the inverter terminal. * The utility voltage may be over the Slow OVR setting during operation. Check the utility voltage on the inverter terminal. * The country or Grid setting could be incorrect, so check the country and Grid settings. * There might be a detection circuit malfunction inside the inverter, so check the detection circuit inside the inverter.
