MONEY ORDER OR CHECK ONLY. PLEASE CALL TO PLACE ORDER. The Powerhouse generator cables are capable to hook up two of the Powerhouse 2100 watt generators in order to convert them into a 4200 watt generator and they can also be used to parallel together the two 2700 watt Powerhouse generators to get a maximum of 5200 watts of power. The Powerhouse generator inverter technology is very comparative to that of the Honda paralleling generator capability. With the Powerhouse generator cable kit, you simply plug one set of cables into one of your generators and the other set to your other generator. These cables cannot be mixed and matched. The Powerhouse generators must be the same one and have the parallel capability pre-installed on the generator before this system can be utilized.
