I need to bounce an idea off this forum and see if it could work. I wanted to replace my current portable generator with something quieter and more fuel efficient, and be able to run some of the circuits in my house through my transfer panel. The panel connects to the generator through an L14-30 240v twist lock plug. The new units I'm looking at are a pair of Yamaha EF2000is inverter generators, which should power everything I need in an emergency. I know Yamaha sells a kit that lets you run two together for double the amperage output, but it outputs to an L5-20 plug, and obviously won't fit my panel. The only unit they make that has the L14-30 is the EF6500is, and that is a little too much for me to get, but I will be able to get two of the EF2000is units.
I know that the L14-30 consists of two 120v hot wires, one neutral, and one ground. The idea I came up with was to have each generator power one side of an L14-30 receptacle that the transfer panel would connect to, the idea being that each generator will power half of the panel, like a normal generator would. The arrangement would be one generator on one hot wire, the other one connected to the other hot wire, both connected to a common neutral and ground on the receptacle. I believe the Yamahas have floating neutrals, based on the amount of research I've done on them. If it helps, the panel is a Reliance Controls Pro/Tran panel, and it's neutral and ground are attached to their respective bars inside the main breaker panel.
I guess the big question is would this actually work like I think it will?
