6. Operating Instructions

6.1 Powering On/Off

  • To Power On: After ensuring all connections are secure, switch the inverter's power switch to the ON position. The power indicator will light up.
  • To Power Off: Disconnect all AC loads, then switch the inverter's power switch to the OFF position.

6.2 Monitoring

The inverter features displays and indicators to monitor its status:

  • Battery Voltage Monitor: Check the DC input voltage from your battery.
  • Output Voltage Monitor: Verify the AC output voltage supplied to your appliances.
  • Indicators: Observe the Power, Inverter, Charging, and 5V indicators for operational status.

6.3 Using the UPS Function

When the inverter is connected to both a battery and mains AC power, it functions as a UPS:

  • Under normal conditions, the inverter will pass through mains AC power to your connected loads and charge the battery using its three-phase charging method.
  • In case of a mains power outage, the inverter will automatically switch to battery power, providing uninterrupted AC power to your loads.
  • When mains power is restored, the inverter will switch back to mains power and resume charging the battery.

6.4 Charging External Devices (5V USB)

If your inverter model includes a 5V USB interface, you can use it to charge compatible electronic devices:

  • Connect your device's USB charging cable to the inverter's 5V interface.
  • The 5V indicator will illuminate when the output is active.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter:

  • Cleaning: Keep the inverter clean and free from dust and debris. Use a dry cloth to wipe the exterior. Do not use liquid cleaners.
  • Ventilation: Ensure the cooling fan and ventilation openings are not blocked. The smart fan will automatically activate when needed.
  • Connections: Periodically check all electrical connections (battery terminals, AC input/output) to ensure they are tight and free from corrosion.
  • Battery Health: Monitor your battery's health and charge level regularly. The inverter's three-phase charging helps maintain battery life, but external battery maintenance may still be required based on battery type.
  • Storage: If storing the inverter for an extended period, ensure it is fully charged and stored in a cool, dry place.
