What do I do if I have a faulty isolator?

Shut off your system immediately and contact your solar power installer!

In may be possible for your isolator to complete a ‘shutdown’ procedure, which is another way of saying a safe way to turn it off. Take a look at the label on your main switchboard for instructions, or in the paperwork left by the installer, in addition to any instructions provided with the product recall. If you are in any way unsure, speak to a professional!

If you are unable to contact the original solar power installer, contact us and we can arrange a replacement.
