Why does my inverter or logger say it is already registered?

What you will see

• A serial number rejected while adding a new device.
• Equipment visible to an installer but absent from the owner’s account.
• Registration difficulties after buying a property with solar.
• Confusion between an inverter serial and a logger serial.

Why it happens

Solis provides an ownership-change process that requires appropriate authority and supporting information. Existing account associations should therefore be resolved through the platform’s authorised process rather than bypassed.

The correct solution depends on whether the issue concerns owner access, a property transfer, an installer association or a wrongly entered serial. These are different requests.

Ask the supplier to explain any registration that predates delivery. Preserve the answer with the invoice and commissioning record. A successful account transfer does not replace verification of the equipment’s identity and condition.

Which situation is it?

Owner access

You need access to your own plant.

Property transfer

New owner, old account.

Wrong serial

Inverter and logger serials confused.

Use the manufacturer’s ownership-change process. Never use another person’s account.

What you can check yourself

• Copy the exact error message.
• Compare the entered serial with the supplied equipment record.
• Identify the email account intended for the owner.
• Gather the invoice and any property-transfer documentation.
• Share identity documents only through an appropriate verified support channel. Do not publish full records in a public comment thread.

What not to do

• Do not use another person’s account, guess passwords or request an unauthorised unbinding. Do not delete an existing plant before its history and ownership have been reviewed.

When to call us

• Contact us when registration prevents access or the previous account holder is unknown. We can help identify the appropriate support request.
