    FAQ

    Q1: Can I plug this 400W micro inverter directly into a regular household socket?

    Yes. As a grid-tie micro inverter, simply connect your solar panels to the DC input terminals and plug the AC output into a wall outlet using the provided adapter cable. It will feed solar power directly into your home grid.

    Q2: Will this 400W micro inverter provide power during a grid blackout?

    No. As a grid-tied inverter, it requires active grid voltage and frequency to function. In a power outage, it automatically shuts down (anti-islanding protection) to ensure safety for grid repair workers.
