Question you may concern
What capacity battery can be used with it?
It is recommended to use a 12V 100Ah-200Ah lead-acid battery or lithium battery; the larger the battery capacity, the longer the UPS power supply time (e.g., a 100Ah battery can support a 100W device to work continuously for about 10 hours).
How does reverse protection work?
When the positive and negative poles of the battery are reversed, the inverter will automatically cut off the circuit to avoid device damage and ensure power usage safety.
What devices can be powered by this inverter?
Suitable for TVs, fans, computers, and small tools.
What is the working principle of the UPS function?
When the external power supply is normal, the inverter powers the device and charges the battery; when the external power supply is interrupted, it automatically switches to battery power to ensure uninterrupted operation of the device.
