Unable to output AC power

Thank you for contacting us. To help us quickly diagnose and resolve the issue with your device, please provide the following information:

Please confirm which of the following scenarios applies:

Scenario A: The device is unable to power connected appliances while simultaneously charging (via AC or solar input).
Scenario B: The device is unable to power connected appliances when running solely on battery storage.

Device status information:
What is the State of Charge (SOC) displayed on the device at the time the issue occurs?

Is the AC output button’s indicator light illuminated?

Does the device’s LCD display show any error messages or fault codes?

Appliance details:
Please provide the name, model number, and rated power (in watts, W) of the appliance(s) that are not receiving power.

Basic troubleshooting:
When using the same AC output socket, do other appliances power up and operate normally?

To speed up our assessment, a photo or short video showing the fault condition — for example, an error code displayed on screen — would be extremely helpful.

We understand this may take a few moments of your time, but the detail you provide will directly support our ability to identify the root cause and deliver the most effective solution.

We look forward to your reply.
