5. Operating Modes

The inverter offers five distinct operating modes to optimize power management based on your specific needs.

1. AC Priority Mode:

   In this mode, the inverter prioritizes AC input (utility or generator) to power the load and automatically charges the battery. If AC input is lost, the inverter switches to battery power.
2. Battery Priority Mode:

   The inverter primarily uses battery power to supply the load. If the battery voltage drops below the low voltage protection threshold, it transfers to AC input. Once the battery is sufficiently recharged, it switches back to battery power.

3. ECO Mode:

   Designed for energy saving. If the load is less than 10% of the inverter's capacity, it enters an automatic sleep state and stops output. When the load exceeds 10%, it automatically restarts and resumes normal inversion.

4. Generator Mode:

   This mode is used when an unstable generator (e.g., 240V) is connected to the AC input. The inverter's built-in AVR regulator stabilizes the voltage and frequency (matching 60Hz) to provide a stable output within the normal operating range.
5. Unattended Mode:

   When the battery voltage is low, the inverter enters a power-saving standby state. It will automatically restore normal output once the battery voltage reaches a user-defined restore value (e.g., after solar charging), enabling fully automatic operation without manual intervention.

5.1 Adjustable Settings

• Charging Current: The maximum charging current can be adjusted from 0% to 100% (max 35A). Setting it to 0% disables the charging function.
• Low Voltage Restore/Protect: In Battery Priority and Unattended modes, you can set specific low voltage restore and low voltage protection thresholds for your battery bank.

6. Maintenance

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

• Cleaning: Keep the inverter clean and free from dust. Use a dry cloth to wipe the exterior. Do not use liquid cleaners.
• Ventilation: Periodically check that the ventilation openings are clear and unobstructed.
• Connections: Inspect all electrical connections (DC and AC) regularly to ensure they are tight and free from corrosion.
• Battery Health: Monitor your battery bank's health and charge levels. Ensure the battery type setting in the inverter matches your installed batteries.
• Environmental Conditions: Ensure the inverter is operating within its specified temperature and humidity ranges.
