Selecting a standby generator ATS is not simply a matter of matching the generator kW rating. The transfer switch must match the actual load current, system voltage, phase arrangement, neutral…

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…
