6,500 W running, 8,125 W surge — sustains the furnace blower, sump pump or a window AC tier and everything below it.
Best forHomeowners with a 30-amp transfer inlet who want a mid-size gasoline generator with CO shutdown and a national parts network.
A middle-weight open-frame that fits a manual transfer switch or interlock cleanly: the L14-30R twist-lock outlet takes a standard 30-amp inlet, and 6,500 running watts handles a furnace, fridge, sump and well pump with room to spare. COsense, Generac's carbon monoxide shutdown, is standard, which matters because most portable-generator deaths come from running one too close to the house. PowerRush raises the starting capacity to 8,125 watts so a well pump or small AC is less likely to stall it. The sheet gives no decibel figure, which is a flag in itself, and owners describe it as a typical loud open frame. Gasoline only means stale fuel and carburetor gumming if it sits, so anyone buying for storm backup should plan on stabilizer and a yearly run. At $999 it undercuts the 7,500 W Westinghouse and costs about what other 6,500 to 7,500 W open frames do, with the brand's dealer and parts network as the extra.
