My home has a Connecticut Electric EmerGen Switch #10-7500 with a 4 prong 30 amp locking power inlet. I also have a Goal Zero Yeti 1500X Power Station (a lithium battery and inverter). Is it possible to supply power from the Yeti to the transfer switch? If so, what kind of cable or other adapters do I need? My goal is to be able to keep a few essential systems powered during an outage.
GoalZero sells a Yeti Home Integration Kit compatible with my model that includes a transfer switch with a 3-prong inlet, with a cable that plugs into the Yeti's Type B outlet on the other side. Their support told me that if I already have a transfer switch, I just need an appropriate heavy-duty cable to connect the two.
