Setup and Installation
Proper installation is crucial for the safety and performance of your inverter and battery system. It is highly recommended that installation be performed by a qualified technician.
1. Unpacking and Inspection
- Carefully unpack all components: one Luminous Cruze+ 2KVA Pure Sine Wave Inverter and two Luminous RC 18000 150 Ah Tall Tubular Batteries.
- Inspect all items for any signs of physical damage. Report any damage to your supplier immediately.
- Ensure all included accessories, such as cables and the instruction manual, are present.
2. Site Selection
- Choose a well-ventilated area, away from direct sunlight, moisture, and flammable materials.
- The installation surface must be flat, stable, and capable of supporting the combined weight of the inverter and batteries.
- Maintain adequate clearance around the inverter for proper airflow and cooling.
3. Battery Connection
The system requires two 12V batteries connected in series to achieve a 24V DC input for the inverter.
- Position the two RC 18000 150 Ah Tall Tubular Batteries securely.
- Connect the positive terminal of the first battery to the negative terminal of the second battery using the provided series connection cable.
- Connect the remaining positive terminal of the second battery to the positive terminal of the inverter.
- Connect the remaining negative terminal of the first battery to the negative terminal of the inverter.
- Ensure all connections are tight and secure to prevent arcing and ensure efficient power transfer.
