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:

1. Specific circumstances in which the issue occurs:

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 operating solely on stored battery energy.

2. Device status information:
What is the current state of charge (SOC) displayed on the device when the issue occurs?

3. Is the AC output button’s indicator light illuminated?

4. Does the LCD display show any error messages or fault codes?

5. What voltage reading is shown in the top-right corner of the screen? (Is it 0 V, or 220 V or higher?)

6. Details of the affected appliance(s):
Please provide the appliance name, model number, and rated power (in watts, W).

7. Basic troubleshooting step:
When using the same AC output socket, does the device successfully power other appliances?

To speed up resolution, a photo or short video showing the fault condition—such as an error code displayed on screen—would be extremely helpful.

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

We look forward to your reply.
