How Much Can Manual Switching Save?

Looking for opinions on how much one can save by installing a manual switch for powering the house from the truck vs the automatic switching? My logic is that, if the power goes out during the day, I will know immediately to switch, if it goes out at night, I will know when I get up and then can switch, if it goes out while I am away, I am probably in the truck anyways. Thoughts?

For sure this is the way to go if you you can get away with just the single 30 amp 240 source. That is, you won’t get the full 9.6kW. A backup generator hookup that covers only a few select circuits should probably work. For example, during a power outage the 30 amp pro power outlet could run my refrigerator, chest freezer and some lights but not the well pump, heat pumps, oven, etc.

To get the full 9.6kW, the truck pumps DC current straight from the truck battery to a large inverter in the (very expensive) home integration system.
I agree, and with little effort, you could manually attach ‘cord’ with 240 plug to the high-power appliances like heat pump, hot water heater, AC, Oven, etc…then plug them into the truck when needed. You won’t be able to use them all at once, but you wouldn’t need to anyway in a real power loss situation. Just read the info plate for power use of each device and use less than total 9600 Watts plugged into the truck at once. Make sure the wire and plug are rated for the amps the particular appliance draws.
