Setup

Follow these steps for proper setup:

1. Placement: Choose a dry, well-ventilated area for the inverter. Ensure there is sufficient space around the unit for airflow.
2. Grounding: Connect the earth wire from the inverter's grounding terminal to a reliable earth ground. This is crucial for safety.
3. Battery Connection:
   • Connect the red battery cable to the positive (+) terminal of the inverter and the positive (+) terminal of your 24V DC battery bank.
   • Connect the black battery cable to the negative (-) terminal of the inverter and the negative (-) terminal of your 24V DC battery bank.
   • Ensure all connections are tight and secure to prevent arcing and overheating.
4. Remote Control Connection (Optional):
   • For the wired remote, connect its cable to the designated remote port on the inverter.
   • The wireless remote operates without direct cable connection to the inverter.
