Warning: Reversing the battery polarity may cause irreversible controller damage. Battery reverse-polarity wiring protection is not provided.

Step 5: Connect the Solar Panel Array

1. Confirm that the photovoltaic array remains isolated.

2. Identify the correct solar input terminals.

3. Connect the photovoltaic wiring according to the specified wiring diagram.

4. Verify correct polarity.

5. Confirm that the array specifications meet the controller's electrical requirements.

6. Secure all wiring connections.

Step 6: Inspect the Electrical Connections

Before applying power:

1. Check all battery connections.

2. Inspect all photovoltaic connections.

3. Verify positive and negative terminal polarity.

4. Confirm that electrical connections are secure.

5. Check grounding and applicable protective devices.

Step 7: Activate the Battery Connection

1. Close the battery fuse or breaker.
