4.2 Cableado
All wiring must comply with applicable electrical codes and be performed by a qualified electrician.
- Conexión a terra: Connect the inverter's chassis ground terminal to a reliable earth ground using appropriate gauge wire.
- Conexión de entrada de CC:
- Ensure the battery bank voltage é 12VDC.
- Use appropriately sized cables for the DC input to minimize voltage drop and ensure safety. Refer to cable sizing charts based on current and distance.
- Connect the positive (+) terminal of the battery bank to the red (+) terminal on the inverter.
- Connect the negative (-) terminal of the battery bank to the black (-) terminal on the inverter.
- Install a DC-rated fuse or circuit breaker between the battery bank and the inverter's positive terminal, as close to the battery as possible.
- Conexión de saída de CA:
- Connect your AC loads to the hardwire AC output terminal block.
- Ensure the total load does not exceed the inverter's continuous power rating (3000W).
- Control remoto (opcional): Connect the remote control unit to the RJ45 port or use the green terminal for external ON/OFF control if desired.
5. Instrucións de funcionamento
5.1 Acendido/Apagado
- Para acender: Ensure all DC and AC connections are secure. Flip the main power switch on the inverter's rear panel to the 'ON' position. The Power LED indicator should illuminate.
- Para apagar: Disconnect all AC loads from the inverter. Flip the main power switch to the 'OFF' position.
5.2 Indicadores LED
The inverter features 3-color LED status indicators on the control panel (refer to Figure 4) to provide operational feedback:
- LED verde: Indicates normal operation and power output.
- LED amarelo: Indicates a warning condition, such as low battery voltage or high temperature. The inverter may continue to operate but requires attention.
- LED vermello: Indicates a fault condition, such as overload, short circuit, or severe over/under voltage. The inverter will shut down to protect itself and connected devices.
5.3 Configuración do interruptor DIP
The DIP switches on the control panel allow for customization of certain inverter parameters, such as output voltage, frequency, and power saving mode. Refer to the detailed specifications table (Figure 5) or the product datasheet for specific configurations. Always adjust DIP switches when the inverter is powered off.
6. Mantemento
Un mantemento regular garante a lonxevidade e o funcionamento fiable do seu inversor.
- Limpeza: Limpa periodicamente o exterior do inversor cun pano seco. Asegúrate de que as aberturas de ventilación estean libres de po e residuos. Non empregues produtos de limpeza líquidos.
- Conexións: Regularly check all electrical connections (DC input, AC output, ground) for tightness and corrosion. Loose connections can cause overheating and poor performance.
- Inspección da batería: Inspect batteries for signs of damage, corrosion, or electrolyte leakage. Ensure battery terminals are clean and tight.
- Ambiente: Verifique que o ambiente de funcionamento se manteña dentro dos rangos de temperatura e humidade especificados.
