Eversolar Inverters – Relay Check Fail

Eversolar TL2000
Eversolar TL2000

Eversolar TL1500, TL2000 and TL2500 models may show the error “Relay Check Fail” on their display. When a grid-tied inverter is first powered up it performs several tests, and this particular error means that the grid connect relay has failed. This is the most common fault that we have experienced with these models.

Our Solis range of inverters are excellent quality replacements and they have identical connectors so there’s no electrical work involved. Give us a call if you’re unsure which one you require.

We also offer an installation service if you do not wish to get involved in the replacement. Contact us for more information.

If you know you require a visit from a service technician then please be aware that we are in Lancashire and can only travel within Lancashire and neighbouring counties.
Please note that we are a small company and can only offer a call out service within a reasonable travelling time from Chorley, Lancashire. We can send spare parts and replacement inverters via courier anywhere within the UK.
e.g. Are there any fault codes or messages on the inverter screen? Any unusual noises or smells?
If your inverter is at fault then we will definitely need to know what panels are connected to it. Many companies installed a poor choice of inverter the first time round. If we know what your panels are then we can get you the right one.
Please select an option. If not known then please choose 'Unknown'. If not listed please choose 'Other'
Your inverter model number and serial number can usually be found on a label on the side or underside of your inverter.
If it's around 5 years, is it over or under? This is important as most inverter warranties are 5 years.
Why do we ask this? Certain companies made consistently the same mistakes/short cuts with their installations and this often gives us a clue as to what might be wrong.
A picture speaks a thousand words! If you have any photos or other documents that can help us understand your installation then please upload them here. Particularly useful are photos of the inverter model number sticker, the connections into the inverter and an overall picture of the inverter area showing all isolators etc.
