Many buyers assume pairing a generator with a separately purchased ATS is simpler or more flexible - but sourcing them separately often introduces avoidable risks:

For most buyers - especially those managing tight project timelines - an integrated system reduces coordination effort and installation risk compared to sourcing components separately.

Choosing the right system starts with understanding your facility's actual power needs:

Calculate Total Load

Add up the running wattage of all equipment that must stay powered during an outage - including motors, HVAC systems, lighting and critical electronics. Don't forget starting (inrush) current for motors, which can be several times higher than running current.

Apply a Safety Margin

It's standard practice to size the generator above calculated peak load - typically with headroom for future load additions and to avoid running the unit at its absolute maximum continuously.

Determine Prime vs. Standby Requirement

If the generator will serve as backup power only during utility outages, a standby-rated unit is typically sufficient. If it will run for extended periods as a primary power source, a prime-rated unit built for continuous operation is more appropriate.

Match the ATS Amperage

The ATS must be rated to handle your total connected load, matched to your generator's output capacity and your facility's voltage/phase configuration.

 

Confirm with a Qualified Technical Team

Because incorrect sizing can lead to overload, nuisance tripping, or unnecessary equipment cost, it's advisable to confirm your final configuration with the supplier's technical team before finalizing an order.
