What does DC Injection (F01, F02, F03) mean on my Delta RPI M30A Inverter?
If your Delta Inverter displays 'DC Injection (F01, F02, F03)', it could be because the utility waveform is abnormal or a detection circuit malfunction. Check the utility waveform, ensuring the grid connection of the inverter is far away from non-linear loads if necessary, and inspect the detection circuit inside the inverter.
What does Ground Cur. (F24) error mean on my Delta Inverter?
If your Delta Inverter is showing a 'Ground Cur. (F24)' error, it could be due to a PV array insulation fault, large PV array capacitance between Plus to Ground or Minus to Ground, malfunction of either side of boost driver or boost choke, or a detection circuit malfunction. Check the insulation of Solar inputs, check the capacitance (+ GND & - GND), which must be less than 2.5uF, and install an external transformer if necessary. Also, check the boost driver & boost choke, and inspect the detection circuit inside the inverter.
What causes HW FAN (W11) error on my Delta RPI M30A Inverter?
If your Delta Inverter displays 'HW FAN (W11)', it could be due to one or more locked, defective, or disconnected fans, or a detection circuit malfunction. To fix this: 1. Remove any objects stuck in the fan(s). 2. Replace any defective fan(s). 3. Check the connections of all fans. 4. Check the detection circuit inside the inverter.
What does Solar2 Low (W02) mean on my Delta RPI M30A Inverter?
If your Delta Inverter displays 'Solar2 Low (W02)', it could be because the actual Solar2 voltage is under the limit, some devices were damaged inside the inverter if the actual Solar2 voltage is close to "0", or a detection circuit malfunction. Check the Solar2 voltage connection to the inverter terminal, check all switching devices in boost2, and inspect the detection circuit inside the inverter.
What does Solar1 Low (W01) mean on my Delta RPI M30A?
If your Delta Inverter displays 'Solar1 Low (W01)', it could be due to the actual Solar1 voltage being under the limit, damaged devices inside the inverter if the actual Solar1 voltage is close to "0", or a detection circuit malfunction. Check the Solar1 voltage connection to the inverter terminal, inspect all switching devices in boost1, and check the detection circuit inside the inverter.
What does SPD Fail mean on my Delta RPI M30A?
If your Delta Inverter is showing 'SPD Fail', it could be due to the inverter being struck by lightning, one or more defective SPDs, disconnected SPDs, or a detection circuit malfunction. Check the inverter's status, replace any defective SPDs, check the connections of the SPDs, and inspect the detection circuit inside the inverter.
What does HW Con. Fail (E08) mean on my Delta Inverter?
If your Delta Inverter displays 'HW Con. Fail (E08)', it could be due to a wrong connection in the AC plug or a detection circuit malfunction. Check the AC connection, ensuring it accords with the manual, and inspect the detection circuit inside the inverter.
What causes Solar2 High (E31) error on my Delta Inverter?
If your Delta Inverter displays 'Solar2 High (E31)', it may be due to the actual Solar2 voltage being over 1000Vdc, or a detection circuit malfunction. To fix this, modify the solar array setting to ensure the Voc is less than 1000Vdc and check the detection circuit inside the inverter.
What causes Solar1 High (E30) error on my Delta Inverter?
If your Delta Inverter shows 'Solar1 High (E30)', it could be caused by the actual Solar1 voltage exceeding 1000Vdc or a detection circuit malfunction. To resolve this, modify the solar array setting to ensure the Voc is less than 1000Vdc and check the detection circuit inside the inverter.
Why is my Delta RPI M30A Inverter showing AC Freq Low (E02)?
If your Delta Inverter displays 'AC Freq Low (E02)', it could be because the actual utility frequency is under the UFR setting, the country or grid setting is incorrect, or the detection circuit is malfunctioning. To address this, check the utility frequency on the inverter terminal, verify the country and grid settings, and inspect the detection circuit inside the inverter.
