Proper installation is crucial for the safe and reliable operation of your inverter.
Iṣagbesori
- Yan ibi gbigbẹ, tutu, ati ibi ti afẹfẹ yoo wa daradara.
- Mount the inverter securely to a stable surface.
- Ensure there is adequate clearance around the inverter for proper airflow and cooling.
Asopọmọra
- Asopọ igbewọle DC: Connect the DC input cables from your 12V battery bank to the inverter's DC input terminals. Ensure correct polarity (positive to positive, negative to negative) and secure connections. Use appropriately sized cables to minimize voltage ju.
- Ilẹ ẹnjini: Connect the inverter's chassis ground terminal to a reliable earth ground or vehicle chassis using a suitable ground wire.
- Asopọ jade AC: Plug your AC loads directly into the inverter's AC output receptacles. Ensure the total wattage of your connected devices does not exceed the inverter's continuous power rating.
