FAQ
What devices can be powered by this inverter?
Suitable for TVs, fans, computers, and small tools.
Can it drive a 3000W air conditioner?
Yes. Air conditioners have instantaneous power during startup (about 2-3 times the rated power), and this product has a peak power of 6000W, which can meet the startup and operation needs of a 3000W air conditioner; the battery capacity must be ≥150Ah to ensure continuous power supply.
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.
Is the cooling fan noisy?
The fan is designed for heat dissipation and will make some noise during operation, but it is within a reasonable range and will not interfere with normal use.
