Click steps to track your progress.

1. 1

   Verify stable DC input voltage from the solar array and AC grid voltage at the inverter terminals are within specified operating ranges.

2. 2

   Inspect cooling fans and heatsinks for proper operation and obstructions, ensuring adequate thermal dissipation within the device.

3. 3

   Check the system's event logs and diagnostic menus for any additional fault codes or recurring patterns associated with the internal memory error.
