The Generlink is designed as an alternative to a transfer switch. There are some differences between the two.
A transfer switch may require re-wiring of your home’s electrical system, The Generlink is installed right after the meter and feeds power right to the panel.
Transfer switches often have 6-8 hard wired circuits which limits the number of circuits you can connect to a transfer switch. This limits the number of appliances and outlets you want to power through the transfer switch. The Generlink is mounted right after the meter feeding power to the entire breaker panel Meaning you can pick and choose which appliances and outlets you want to power by isolating them at the breaker panel up to the capacity of your generator.
Transfer switch usually only has a few 240 volts circuits which restricts you on the big appliances you want to operate while the power is out like your hot water heater or over. Where the Generlink supplies power to your entire power breaker so you can power any appliances you want if the generator that you have will handle the load.
