There are two different types of transfer switches: manual and automatic. For portable generators, the ideal choice is to use manual transfer switches, which means in case of power outages, the switch must be manually flipped. Automatic transfer switches, on the other hand, turn on the generator automatically during a power outage, making them the best choice for standby generators.

The average generator transfer switch installation cost for manual transfer switches ranges from about $400 to $1,300. This includes all the costs of materials and labor. For automatic transfer switches, the average generator transfer switch installation cost is something between $600 and $2,000.

For residential standby generators that do not require complex installs, the average cost of generator installation without the generator itself ranges from $3k to $5k. However, for longer distances or powers above 20 kW which require complex installs, the cost would start at about $5k to more than $12k on average.

There are costs that you may not necessarily pay for such as liquid propane tanks when you use a natural gas generator, but a breakdown of standby generator installation cost factors is listed below for a better understanding of possible costs:

  • Permits : $80 – $450
  • Electrician labor charges (per hour) : $40 – $100
  • Generator transfer switch installation : $400 – $2,000
  • Electrical wiring (per foot) : $6 – $8
  • Gas line (per foot) : $12 – $25
  • Concrete pad : $150 – $400
  • Propane tank : $400 – $1,800

Note that complex generator installations may require higher labor and material costs.

    If you need a standalone switcher, Xantrex is a reasonable size from a trusted company. Simple and clear circuit diagram. You may need to add a male and female connector or connect directly to your system as needed.

  2. I set the Go Power transfer switch to switch between an inverter and an external power force( Shore or Gennie). I wired one of my outlets( and the battery bowl) to only turn on when using external power to avoid creating a” circle” where my battery/ inverter feeds the bowl. I added a 15 amp/ 250v panel fuse to cover the line feeding my charging socket. It works veritably well.
