Failure to follow these safety instructions may result in serious injury or damage to the inverter and connected equipment.

• Do not connect the inverter directly to grid power. This can cause severe damage to the inverter and pose an electrical hazard.
• Onetsetsani polarity yolondola. Reverse connection of positive and negative terminals is strictly forbidden and will damage the unit.
• Avoid overloading the inverter. For inductive loads (e.g., motors, refrigerators), select an inverter with a continuous power rating 3-7 times higher than the appliance's wattage. For refrigerators, a 10 times higher power inverter is recommended.
• Proper power-up and shut-down sequence: Turn off the load first, then turn off the inverter. When powering on, turn on the inverter first, then turn on your loads. This prevents unstable output during the initial seconds due to the soft start function.
• Use standard battery cables. Using non-standard or undersized cables may prevent the inverter from delivering full output.
• Kuyika pansi: Ensure proper grounding to protect against electrical leakage.
• Kutentha: The intelligent cooling fan activates when the internal temperature exceeds 50°C (122°F) to prevent overheating.

6. Kuyika

Proper installation is crucial for the inverter's performance and safety. Consult a qualified electrician if you are unsure about any steps.

6.1 Kukwera

• Mount the inverter in a dry, well-ventilated area, away from direct sunlight, heat sources, and flammable materials.
• Ensure adequate clearance around the inverter for proper airflow, especially around the cooling fans.
• Securely fasten the inverter to a stable surface using appropriate mounting hardware.

6.2 DC Input Connection (48V)

• Connect the supplied red cable to the positive (+) terminal of your 48V battery bank and the positive (+) terminal on the inverter.
• Connect the supplied black cable to the negative (-) terminal of your 48V battery bank and the negative (-) terminal on the inverter.
• Ensure all connections are tight and secure to prevent loose contacts and voltage madontho.
• Zofunika: Double-check polarity before making final connections. Reverse polarity will damage the inverter.

6.3 AC Output Connection (120V)

• Malo Okhazikika: Plug your 120V AC appliances directly into the dual AC outlets.
• Hardwire Terminal: For permanent or high-power installations, connect your AC wiring to the hardwire terminal (L for Live, N for Neutral, G for Ground). Ensure correct wiring and consult local electrical codes.

7. Ntchito

7.1 Kuyambitsa Inverter

1. Ensure all DC input connections are secure and correct.
2. Ensure no AC loads are connected or turned on.
3. Flip the power switch on the inverter to the 'ON' position. The LED display should illuminate, showing DC input voltage ndi AC kutulutsa voltage.
4. Once the inverter is stable (after a few seconds), you can connect and turn on your AC loads one by one.

7.2 Shutting Down the Inverter

1. Turn off all connected AC loads.
2. Unplug AC appliances from the outlets or disconnect from the hardwire terminal.
3. Flip the power switch on the inverter to the 'OFF' position.

8. Kusamalira

• Regularly inspect all electrical connections for tightness and corrosion.
• Keep the inverter's ventilation openings clear of dust and debris to ensure proper cooling.
• Clean the exterior of the inverter with a dry, soft cloth. Do not use liquids or abrasive cleaners.
• Check the fuses periodically. Spare fuses are provided for replacement if needed.
