How does the UPS function of this inverter work?
When the external power supply is normal, the inverter powers the device while charging the battery; when the external power supply is interrupted, it automatically switches to battery power to ensure uninterrupted operation of the device.
What devices can be powered by this inverter?
Suitable for TVs, fans, computers, and small tools.
Is customization available?
OEM/ODM support for logo, color, and packaging design.
Does it include protection features?
Yes, it has sixfold safety protection for reliable performance.
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.
