Unfortunately, Sunteams inverters are no longer available or supported in Australia. Have you tried shutting the system down and re-starting it?
If you can see something on the display and lights, that suggests that your panels are working fine. Shutting your system down and leaving it for about 15 minutes, then res-starting it sometimes fixes the issue. If after you’ve done this you continue to experience problems, fill in the form below and send us the information. Once we have your information we can suggest a viable replacement.
