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 when 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 running 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? (e.g., 0 V or above 220 V?)

6. Details of the affected appliance(s):
Please provide the appliance name, model number, and rated power consumption (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 — for example, an error code displayed on screen — would be extremely helpful.

We truly appreciate the time you’re taking to provide these details. Your input enables us to pinpoint the root cause and deliver the most effective solution.

We look forward to your reply.
