[RE-wrenches] Generators and Grid-tie Systems

[Jonathan Hill]

What brands of generators have you had good experience synching with off-grid inverters (Outback, Magnum, Xantrex)? We sell Kohler, but we'd like to offer an alternative (that we could sell). I've heard good things about Honda, but I've heard that you need to be a Honda dealer to sell them. Any suggestions?
