3. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your KEMOT PROsinus-700 inverter. Ensure the installation area is well-ventilated, dry, and free from direct sunlight or excessive heat sources. The unit requires an external 12V DC battery (not included) for emergency power functionality.

3.1 Connecting the Battery

Connect the positive (+) terminal of a 12V external battery to the red (+) battery terminal on the rear of the inverter. Connect the negative (-) terminal of the battery to the black (-) battery terminal on the inverter. Ensure connections are secure and tight to prevent arcing and ensure optimal performance. Use appropriate gauge cables for the battery connection.

The cooling fan is prominently featured at the top center.

3.2 Connecting to Mains Power

Plug the inverter's integrated power cable into a standard 230V AC wall outlet. This connection allows the inverter to charge the external battery and to pass through mains power to connected loads when available.

3.3 Connecting Loads

Connect your appliances (loads) to the 230V AC output sockets on the rear of the inverter. Ensure that the total power consumption of all connected devices does not exceed the inverter's rated output power of 700W.

4. Operating Instructions

4.1 Powering On and Off

  1. To Power On:
    • Ensure the battery and mains power connections are secure.
    • Press the 'Mains ON/OFF' switch to the 'ON' position. The inverter will begin charging the battery and passing mains power to the outputs.
    • Press the 'Output & Inverter ON/OFF' button to activate the inverter output. The LED display will illuminate, showing the current status.
  2. To Power Off:
    • Press the 'Output & Inverter ON/OFF' button to deactivate the inverter output.
    • Press the 'Mains ON/OFF' switch to the 'OFF' position.
    • Disconnect the inverter from the mains power outlet and the battery if the unit will not be used for an extended period.

4.2 Understanding the LED Display

The LED display provides critical information about the inverter's operation. Refer to the icons and numerical values to understand the current status:

4.3 Automatic Operation (UPS Function)

When the inverter is connected to both mains power and a charged battery, it will automatically switch to battery power (inverter mode) in the event of a mains power failure. This transfer typically occurs within 4 milliseconds, ensuring minimal interruption to connected devices. Once mains power is restored, the unit will automatically switch back to mains operation and resume charging the battery.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your KEMOT PROsinus-700 inverter.
