I hope this finds you well.
I had an interesting event last week. Some critter chewed through one of my home power leads. (We have underground cable.) This caused half the house to go dark. Mostly, the part that was out was the part that runs my refrigeration. I hooked up one Honda EU2000 to the transfer switch. Two refrigerators only drew 400 watts. Nothing thawed, which was very good news. The power company was out that evening with a temporary fix and had a new cable run by noon the next day. Easy.
I also rolled my Whynter 95 qt freezer out onto the patio and plugged that into a second EU 2000. It pulls 70 watts and runs on 120 vac, 12vdc or 24vdc. No, I have not built the gizmo that allows two generators to run in tandem synchronized. Turns out I did not need it anyway, based on 400 watts of draw plus this 70. I find this particular freezer economical with a low power draw and a price that is a good $500 below the price of other dc powered units. And, yes, I have a couple solar panels that would take care of the freezer plus some light.
My interesting observation is that the exhaust was a problem. My house is 40 feet from my neighbor. Both of us have two stories. The zone between them was pretty unbearable due to the exhaust. I must run some sort of pipe up the side of the house, if I am going to run both. – R.V.
