4.5 Configurações do interruptor DIP
The inverter features DIP switches for configuring output frequency and voltage. Refer to the specifications table (Section 7) or the product label for specific settings. Ensure the inverter is powered off before adjusting DIP switches.
- Frequência de saída: Select 50 Hz or 60 Hz based on your regional requirements.
- Volume de saídatage: Selecione o volume de saída CA desejadotage (e.g., 230VAC for this model).
5. Instruções de operação
5.1 Ligar/Desligar
After all connections are secure and verified, switch the main power button on the inverter to the 'ON' position. The LED indicators will illuminate to show the inverter's status. To power off, switch the button to 'OFF'. A remote control terminal is also available for external ON/OFF control.
5.2 Indicadores LED
The 3-color LED indicators provide visual feedback on the inverter's operational status and any potential faults. Consult the product documentation or the specifications table for a detailed explanation of each LED state.
5.3 Modo de economia de energia
The power saving mode can be adjusted via a variable resistor. This feature helps reduce quiescent current draw when no load or a very light load is connected, conserving battery power.
5.4 Conexão de cargas CA
Plug your AC appliances into the inverter's AC output socket. Ensure the total power consumption does not exceed the inverter's continuous power rating (2000W for this model). For inductive loads (e.g., motors, refrigerators), consider their surge power requirements, which can be significantly higher than their running power.
6. Manutenção
Regular maintenance ensures optimal performance and extends the lifespan of your inverter.
- Limpeza: Mantenha o inversor limpo e livre de poeira. Use um pano seco para limpar a parte externa. Não use produtos de limpeza líquidos.
- Ventilação: Periodically check that the cooling fan and ventilation openings are clear of obstructions.
- Conexões: Inspect all DC and AC connections regularly to ensure they are tight and free from corrosion. Loose connections can cause overheating and poor performance.
- Manutenção da bateria: Follow the manufacturer's recommendations for your battery bank's maintenance.
7. Solução De Problemas
If the inverter is not functioning correctly, refer to the following common issues and solutions:
- Sem potência de saída:
- Check DC input connections and battery voltage.
- Verify the inverter's power switch is ON.
- Check for blown DC input fuses (if applicable).
- Indicação de sobrecarga:
- Reduza a carga total conectada ao inversor.
- Disconnect and reconnect the load to reset the inverter.
- Over Temperature Indication:
- Ensure adequate ventilation around the inverter.
