Bypass Mode (Optional, if equipped)

• Use only during stabilizer fault – routes direct mains to appliance. Do not use long-term.

Step 1: Location Selection

• Ventilation: Place the unit in a well-ventilated area. Do not enclose it in a cabinet. The manual warns that heat buildup reduces battery life and inverter efficiency.
• Distance from Battery: Keep the inverter as close to the battery as possible (ideally less than 3 meters) to minimize voltage drop through the cables.
• Environment: Avoid direct sunlight, water splashes, and areas with high humidity (like a bathroom).

Step 2: Mounting

The manual instructs you to use the metal keyhole slots on the back of the unit.

1. Mark the wall for two screws at a distance matching the slots.
2. Use heavy-duty wall plugs (provided) if mounting on concrete.
3. Hang the inverter securely. It should not wobble.
