Top 6 China Automatic Transfer Switches Manufacturers

Do solar inverters need a transfer switch?

In some cases, the solar system does not connect to the grid. So the auto solar transfer switch must toggle the load between the PV system and a different source, such as a generator. But solar inverters usually come with built-in mechanisms to switch between power sources. So, where would you need the transfer switch?

What is a solar automatic transfer switch?

An automatic transfer switch, ATS, does that automatically, in your absence. Read more about the solar ATS below. A solar automatic transfer switch is a type of self-acting switch that is specifically designed for use with a solar power system. Solar ATS are typically installed so they connect to the grid, inverter, solar battery, and the load.

Can you use an automatic transfer switch on an off-grid Solar System?

You can also use the automatic transfer switch for off-grid solar systems in different electrical systems, whether residential or commercial. That said, the off-grid switch is more common in remote locations where it is not feasible to run a utility line. Also, in RVs when connecting to shore power or generator.

What is an automatic transfer switch?

An automatic transfer switch is an intelligent power switching device that is automatic, self-acting, and works by a controlled logic. The main purpose of an automatic transfer switch is to make sure that there is a continuous supply of utility power from the alternative power source when the primary source is not there.

How does a solar transfer switch work?

Solar ATS are typically installed so they connect to the grid, inverter, solar battery, and the load. When battery power goes down, the solar transfer switch will automatically connect your appliances to the grid. This ensures your electrical system continues to operate even when there is no solar power available.

What is a power transfer switch?

If you're new to the transfer switch, here's what it is: A power transfer switch is an electrical device used to safely connect or disconnect a load from its primary power source to another. In the case of a solar system, the load is the home or business that the solar array is powering and the alternate power source is the grid or grid generator.
