4.2 ዲሲ ግቤት ግንኙነት
Connect the inverter directly to a 24VDC battery bank using appropriate gauge cables. Ensure correct polarity: connect the positive (+) terminal of the inverter to the positive (+) terminal of the battery, and the negative (-) terminal of the inverter to the negative (-) terminal of the battery. Use a fuse or circuit breaker on the positive DC line, close to the battery, as recommended by the inverter specifications.

4.4 የርቀት መቆጣጠሪያ ግንኙነት (አማራጭ)
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. የአሠራር መመሪያዎች
5.1 ማብራት / ማጥፋት
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 የጭነት አስተዳደር
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 GFCI ማሰራጫዎች
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.
