Is your Sunny Roo or Sunna solar power inverter showing an Er22 error code on the screen?
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:
- Get the inverter repaired
- 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:
- Pay to have an electrician disconnect the inverter
- Pay to send the inverter to a reputable repair shop
- Pay for the repairs
- Pay to have the inverter returned to you
- 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.

hi
I have this issue, could it be claimed on contents insurance?
I will check with my insurance company but just wondered if you know of anybody that has done this?
Good to hear the success you’ve had Dane! As you mentioned the quality is very poor and for that reason we personally don’t repair these inverters and we certainly don’t recommend that end users with no electrical knowledge open up and work on a solar inverter.
The Error 22 code is as other have said the main output relay fault. These can be actually fixed quite easily if you are handy with a screwdriver. The main problem is the quality of these relays are shocking… the error 22 is caused by the contacts arcing and then eventually sticking. There is a control circuit that detects the lack of power on the output relays and throws up the err 22. If you manage to get the unit disconnected, open up the case (make sure its totally disconnected), locate the 2 black 1 inch by 2 inch relays (above the large collection of capacitors on the top of main board) pop off the plastic tops carefully and run a small piece of wet and dry sanding sheet between the contacts to clean them up. They will be all scarred and burnt but after this they will be clean again. I have done this to a couple of Effekta ES 5000’s which are identical to Sunny Roo and Sunna. It works like a dream!
Hi Greg, sorry to hear of your Sunny Roo issue. Replacing the relay isn’t a simple process as they are manufactured onto the boards inside the inverter. You could go through all the hassle of getting it repaired only to have it fail with another issue sometime soon. I’d highly recommend you bite the bullet, spend a bit more money and have the Sunny Roo replaced with a quality inverter with a full manufacturers warranty. Thanks
My Sunny Roo SR2000TLI
Is saying Relay Failure & will not reboot !
I have removed unit .
And am not sure with replacing or repairing
Can I just buy & install a new Relay ?
Thank you
