5.2 Battery Connection (24V System)
- Connect the red battery cable to the positive (+) terminal of your 24V battery bank and the positive (+) terminal on the inverter.
- Connect the black battery cable to the negative (-) terminal of your 24V battery bank and the negative (-) terminal on the inverter.
- Ensure connections are tight and secure to prevent arcing.
5.3 AC Input Connection
- Connect the provided AC input power cable to the designated AC input port on the inverter.
- Plug the other end of the AC input cable into a grounded 230V AC power outlet or generator.
5.4 AC Output Connection
- Connect your appliances or load to the AC output sockets on the inverter.
- Ensure the total power consumption of connected devices does not exceed the inverter's rated output (2000W continuous).

6.2 Display Indicators
The front panel display provides real-time information about the inverter's status:
- Input Voltage: Shows the incoming AC voltage from the grid or generator.
- Output Voltage: Displays the stable 230V AC output voltage.
- Load Level: Indicates the percentage of the inverter's capacity currently being used.
- Battery Status: Shows the battery charge level and charging status.
- Warning/Error Indicators: Alerts for conditions such as overload, low battery, or overheating.
6.3 Operating Modes (UPS Functionality)
The SinusPro-2500W automatically switches between operating modes:
- AC Mode: When grid power is available, the unit charges the batteries and passes AC power directly to the loads.
- Inverter Mode: When grid power is interrupted, the unit automatically switches to battery power, converting DC to AC to supply the loads.
- Charging Mode: When connected to AC input, the intelligent charger will charge the connected 24V battery bank.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your SinusPro-2500W.
- Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents.
