Q&A
What appliances can this inverter support?
Rated 1500W, peak 3000W – supports most home appliances.
Can it be used in RVs or trucks?
Yes. The device input voltage is DC 12V, which matches the battery voltage of RVs and trucks. It can be connected via battery clips or cigarette lighter interface (need to confirm that the maximum current of the cigarette lighter is ≥10A) to supply power to car refrigerators, parking air conditioners, laptops, etc.
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.
What happens if the positive and negative poles are reversed when connecting the battery?
The device features built-in reverse polarity protection. If the positive and negative terminals are connected incorrectly, the circuit will automatically disconnect to prevent damage to the equipment. Simply adjust the battery clip connections (red clip to positive terminal, black clip to negative terminal), then restore power to resume normal operation.
