What to do if the display of my SolarMax 8MT2 remains blank?
- J
  Janice HowardAug 21, 2025
  If the display is blank, several factors could be at play. First, ensure that the DC disconnector Q1 is switched on. If it is, check if the irradiation is sufficient for operation; if not, wait. Also, verify that the PV generator strings are correctly connected. If these steps don't resolve the issue, and the PV generator connections are correct, it may indicate an internal failure.

What does 'Burst error' mean on my SolarMax 8MT2?
- J
  Justin GrahamSep 1, 2025
  A 'Burst error' indicates that the inverter disconnected from the grid five times or more on the same day. This warning is displayed for the remainder of the day. Check your plant’s status logger in MaxWeb xp (if present) or check the grid parameters. If this happens repeatedly, contact our SolarMax Service Centre.
