4.4 Remote Control Connection (Optional)

The inverter supports a remote ON/OFF control via the green terminal block. Connect a compatible remote switch or control system to this terminal for convenient power management.

5. Instrucións de funcionamento

5.1 Acendido/Apagado

To power on the inverter, ensure all DC connections are secure, then press the main power switch on the front panel to the 'ON' position. Alternatively, if a remote control is connected, use the remote switch. To power off, reverse this process.

5.2 Load Management

The SP-1000-124 provides 1000 watts of continuous power and can handle a surge power of up to 1750 watts for less than 3 seconds. Avoid exceeding the continuous power rating to prevent overload shutdowns. If the inverter shuts down due to overload, reduce the connected load and restart the unit.

5.3 tomas GFCI

The integrated Ground Fault Circuit Interrupter (GFCI) outlets provide enhanced safety by quickly cutting power in case of a ground fault. If a GFCI outlet trips, disconnect the appliance, reset the GFCI, and re-evaluate the appliance for faults before reconnecting.

6. Mantemento

Un mantemento regular garante a lonxevidade e o funcionamento fiable do seu inversor.

• Limpeza: Periodically clean the inverter's exterior with a dry cloth. Ensure ventilation openings and the cooling fan are free from dust and debris. Do not use liquid cleaners.
• Conexións: Regularly check all DC and AC connections for tightness. Loose connections can cause overheating and poor performance.
• Saúde da batería: Monitor the health of your battery bank. A weak or improperly maintained battery can affect inverter performance and lifespan.
