A gas generator can work with an automatic transfer switch, but selecting the ATS is not simply a matter of choosing a “generator ATS.” For generator-set integrators, panel builders, contractors...

Diesel Generator ATS Selection Guide Choosing an ATS for a diesel generator is not simply a matter of matching generator kVA to an ampere rating. A reliable utility-to-generator system must...

Off-Grid & Backup Power ATS Guide An off-grid automatic transfer switch is used when one AC load must transfer automatically between two available AC power sources, such as an inverter...

A hybrid inverter system does not automatically need an external ATS. An automatic transfer switch can be useful when two AC sources—most commonly the utility grid and a generator—must be...

Do you need an automatic transfer switch for an inverter? Not always. Many inverter-chargers and hybrid inverters already include an internal transfer function, a dedicated backup or EPS output, or...

ATS Application Comparison A solar ATS and a generator ATS are not automatically two different types of transfer switch. In many low-voltage systems, the ATS performs the same basic task:...

A solar automatic transfer switch is normally used on the AC side of a PV backup system to transfer a load between two available AC sources, such as grid power...

EV Charging Infrastructure · ATS Selection Guide An automatic transfer switch can be useful at an EV charging station when a load needs to move automatically between two AC power...

BESS · Low-Voltage AC-Side Transfer A battery energy storage system may require automatic source transfer, but the ATS must be used at the correct point in the system. LEEYEE compact...

Railway station auxiliary power systems often need an automatic way to move selected low-voltage loads from a normal source to a standby source. A compact automatic transfer switch can perform...
