Frequently Asked Questions

Which regional plugs are supported by the universal socket?

The universal socket is compatible with most national plug specifications, such as GB, US, EU, etc. (some require adapters), and can meet the use of devices in different regions.

Can this inverter support both 12V and 24V inputs

Yes, it can work with different voltage systems via selectable input terminals.

How to install the battery terminal wire?

Connect the red terminal wire to the positive pole of the battery and the black terminal wire to the negative pole. Ensure the interface is firm and there is no short circuit when connecting.

Can the 3 AC sockets drive high-power devices at the same time?

Yes, but it is necessary to ensure that the total power of the 3 devices does not exceed 2000W (continuous power). For example, it can drive 1 1000W electric oven + 1 500W microwave + 1 400W printer at the same time (total power 1900W), avoiding total power overload to trigger the protection mechanism.
