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 using only stored battery energy.

2. Device status information:
What is the State of Charge (SOC) displayed on the device at the time 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 value is shown in the top-right corner of the screen? (e.g., 0 V or above 220 V?)

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

7. Basic troubleshooting step:
When using the same AC output socket, do other appliances power on and operate normally?

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

We fully appreciate that providing this information may take a little of your time, but the details you share will directly support our ability to identify the root cause and offer you the most effective solution.

We look forward to your reply.
