I had our electrician rig the street power/inverter system so if the power goes out for a long period (we went without power for two days earlier in the year), and there is no more battery mojo to power the inverter, I drag a potable 3.5kw generator outside, crank it up, and plug it into the house power, making sure we are disconnected from the street. He also added a light that shows when we have street power, so I know when to revert to "normal."I'm shopping around for a planta now. I'm leaning towards a Honda super silent 3000K inverter generator.
For long time outages, I'd use it occasionally for an hour or so to recharge batteries via the inverter while the fridge gets cold again, and the rest of the time would be just the inverter.
I'd love to find a Denyo super silent 12k , but they're like hens teeth these days and expensive when you find one.
3.5k is the same as our inverter, so we can power everything the inverter does when necessary.
This simple, inexpensive, elegant system has been a lifesaver several times at Camp Moto.
Of course, if we wanted to run the a/c, water heater or add more electronic gadgets, 3.5k is underpowered. But for temporary needs, it works well.
