Click steps to track your progress.

1. 1

   **Power Cycle:** Safely turn off your solar inverter using its main disconnect switch (and any associated breaker). Wait 5 minutes, then turn it back on. See if the error clears.

2. 2

   **Check Breakers:** Go to your home's main electrical panel. Confirm that all circuit breakers labeled for your solar system are fully in the 'ON' position. If any are tripped (usually in the middle position), switch them fully 'OFF' then firmly back 'ON'.

3. 3

   **Visual Cable Check:** Carefully look at the external cables connected to your inverter and your home's electrical panel. Ensure they appear securely connected and show no visible signs of damage, fraying, or loose connections.

4. 4

   **Contact Professional:** If the 'Over Current' error continues after these steps, or if you notice any burning smells, unusual noises, or visible damage to your system, immediately contact your solar installer or a certified electrician. Do not attempt to open the inverter yourself.
