5. Setup

Before Installation: Ensure the installation location is well-ventilated, dry, and away from direct sunlight or heat sources. The inverter should be mounted securely using appropriate hardware. The included gaskets can assist in stable mounting.

5.1 Mounting the Inverter

• Choose a vertical surface for mounting to optimize heat dissipation.
• Use the provided gaskets and mounting screws to secure the inverter firmly.
• Ensure adequate clearance around the inverter for airflow, especially around the heat dissipation holes and fan.

5.2 DC Input Connection (Solar Panel / Battery)

1. Ensure the DC power source (36V solar panel array or 36V battery) is disconnected or switched off.
2. Connect the positive (+) terminal of your DC source to the positive (+) DC input terminal on the inverter.
3. Connect the negative (-) terminal of your DC source to the negative (-) DC input terminal on the inverter.
4. Verify all DC connections are tight and secure.
5. The DC input voltage must be within the 22-50VDC range.

5.3 AC Output Connection (Grid)

1. Ensure the AC grid connection point is de-energized.
2. Connect the included AC power cord to the AC output port on the inverter.
3. Connect the other end of the AC power cord to a dedicated AC outlet or grid connection point, ensuring it is properly grounded.
4. Confirm that the AC voltage at the connection point is within the inverter's specified range (90V-140V AC).

5.4 Grounding

Proper grounding is critical for safety. Connect the inverter's grounding terminal to an earth ground according to local electrical codes.

6. Operating Instructions

1. Initial Power-Up: After all connections are securely made and verified, first connect the DC power source.
2. Connect to AC Grid: Plug the AC power cord into the grid outlet.
3. Turn On Inverter: Flip the power switch on the inverter to the 'ON' position.
4. Monitor Indicators:
   • The 'RUN' indicator light should illuminate, indicating normal operation.
   • If the 'ERROR' indicator light illuminates, refer to the Troubleshooting section.
5. Normal Operation: The inverter will automatically begin converting DC power to AC power and feeding it into the grid. The MPPT function will optimize power extraction from your solar panels.
6. Shut Down: To power off the inverter, first disconnect the AC power cord from the grid, then switch off the inverter, and finally disconnect the DC power source.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your inverter.

• Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure the heat dissipation holes are free from dust and debris to maintain proper cooling. Do not use liquid cleaners.
• Connection Checks: Regularly inspect all DC and AC connections for tightness and signs of corrosion. Loose connections can lead to overheating or poor performance.
• Environmental Check: Ensure the operating environment remains within specified temperature and humidity ranges.
• Fuse Replacement: If a fuse blows, replace it with a fuse of the same type and rating. Refer to the specifications for fuse details.
