Cost to install

Installation is what turns the unit price into a working standby system: the 200A automatic transfer switch (bundle $6,800–$7,400), the electrical work between switch and panel, the gas plumbing run, the concrete pad and site prep, and the municipal permit. The dataset records a turnkey installed band of $9,500–$13,500 for this model; complex installs with panel upgrades or long gas runs quote higher per site.
