Tips: How to reset this 400W pure sine wave inverter after overload protection is triggered?

• First, disconnect all connected load devices and check whether the total power exceeds 400W (or if the starting power exceeds the limit) to rule out "equipment overload" issues.
• Next, inspect the input voltage (e.g., whether the car battery voltage is below 10.5V or above 15V, as battery undercharge/overcharge may trigger low/high voltage protection, which exhibits symptoms similar to overload protection). If no issues are found, turn off the 400 Watt pure sine wave power inverter's power switch and wait 3-5 minutes (to allow the internal protection circuit to reset).
• Then, turn the switch back on, and the inverter should resume normal operation. If the protection is repeatedly triggered, further troubleshooting of the load or input power source for potential faults is required.
