When the power goes out, a standby generator starts on its own. It is wired into the house and runs on natural gas or propane, so there is nothing to drag out of the garage and nothing to fill in the dark. Below are standby generators we have installed at homes across New Jersey. Each one shows the unit that went in, the transfer switch behind it and the town it is in, and where the homeowner left a review you will find that too. If you are trying to work out what size you need, this is a good place to start.

621 completed standby generator projects across 123 New Jersey towns, including 123 with a review written by the customer.
