Q&A
What power range of devices can it supply?
It supports devices within 360W in UPS mode and within 500W in regular mode. Ensure the device power does not exceed the corresponding limit.
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.
What power appliance can this inverter run?
It has a continuous power of 800W, so it can run appliances within 800W; the peak power is 1500W, supporting the instantaneous startup of appliances within 1500W.
Can this inverter support both 12V and 24V inputs
Yes, it can work with different voltage systems via selectable input terminals.
