5 (100%) 3 votes

Is your Sunny Roo or Sunna solar power inverter showing an Er22 error code on the screen?

Faulty Sunny Roo / Sunna Solar Power Inverter Error Code Er-22 fault code

The Er22 error code is telling you that the output relay inside the Sunny Roo or Sunna inverter has failed. The course of action that the Sunny Roo / Sunna inverter manual recommends to take for an Er-22 fault is to turn the inverter off and wait for the inverter LCD screen to go blank.

When the LCD screen is blank, restart the inverter and see if the fault has cleared and if the system resumes operation.

In our experience it is very rare that a Sunny Roo or a Sunna inverter actually resumes operation after being rebooted from an Er-22 fault as the output relay does not tend to fix itself! If you find that the Sunny Roo or Sunna inverter continues to show the Er-22 fault after being rebooted you really only have 2 choices:

  1. Get the inverter repaired
  2. Replace the inverter with a quality replacement

Sunny Roo or Sunna Er22 Fault – Your Options

1. Repair the inverter. You may feel that this option would be the cheapest option to get your solar power system operational again however is tends to end up being quite expensive as you need to:

  1. Pay to have an electrician disconnect the inverter
  2. Pay to send the inverter to a reputable repair shop
  3. Pay for the repairs
  4. Pay to have the inverter returned to you
  5. Pay to have an electrician reconnect the Sunny Roo inverter

All the above is not going to leave you any change from $500, and after all of that you still have an inverter that is of inferior quality with no warranty as the manufacturer has disappeared. Your best option may be the second option,
2. Replace the inverter with a quality replacement. A quality replacement inverter is the best way to go, yes it will cost a bit more up front but it will give you a reliable inverter and a warranty from a company that should be around to back it if it’s required in the future.
