What is a Solar Battery Changeover Switch?

A Solar Battery Changeover Switch is an electrical device designed to safely switch power supply between a primary source (such as the utility grid) and a backup source (such as a solar battery or generator). It ensures continuous power by transferring the load quickly in case of a power outage or instability.

This switch can operate either manually or automatically, depending on the system design. It is widely used in residential, commercial, and industrial applications where uninterrupted power is essential. With features like fast switching, reliable performance, and safety protection, it helps prevent equipment damage and power interruption risks.
