Paralleling Yamaha 4500W and Honda 2000W

why was the lights changing? was the voltage all over the place?


i would think when they sync, voltage and hertz would sync


i personally think it will either work, or go into overload and protect the inverter.

Naturally the voltage would have to be changing for the lights to vary in brightness. The Outback inverter was running off of battery and can change its contribution to the output instantly. The Honda has a ramp-up/ramp-down delay. I'm "assuming" the two devices were in a slow oscillation loop trading off which one carried most of the load. The Outback's output is around 122 volts steady, the Honda's is 128 volts under lighter loads, ramping down to 120 as the load gets heavy. When the Outback inverter sees a higher voltage than it's producing its bi-directional H-bridge turns into an unregulated battery charger. When I realized I had the outputs cross-connected, I broke the connection without any investigation. A couple of factors here aren't present with generators only.
