Q&A
Can this inverter drive a 3P air conditioner and a refrigerator at the same time?
Yes. The rated power of a 3P air conditioner is about 2200W-2500W, and an ordinary double-door refrigerator is about 150W-300W, with a total power of about 2350W-2800W, which does not exceed the 3000W continuous power; and the peak 6000W can cope with the instantaneous startup impact of the air conditioner. When using, ensure the battery capacity is ≥200Ah (12V) to ensure battery life.
What is the reason for the inverter automatically shutting down during operation?
It is likely that the protection mechanism is triggered: 1. Load overload (total power of connected devices exceeds 1000W); 2. Abnormal input voltage (battery voltage <10.8V or >14.5V); 3. Device overtemperature (excessively high ambient temperature or cooling fan failure). It is recommended to disconnect some loads, check the battery voltage or clean the heat dissipation port before trying again.
Does it have a charging (UPS) function?
No, this model is a pure inverter without UPS function.
