We live in a rural location with a rather unreliable mains power supply and without mains water. So besides the normal household appliance such as fridges, lighting, electric stove and oven, washing machine, TV, computers and integrated air-conditioning throughout a quite large (350 sq./m) house, we have a deep bore emergency water supply (pump 750 Watt/ 5,750 Watt starting load) and in-ground water tank (pump 1700 Watt running 9,200 Watt starting load).Read more the air-con or water tank pump to run off the generator.
After connecting the Honda EU70 to my home via transfer a switch in our main power-board (allow around $1,000) the electrician asked for lighting and appliances to be progressively turned on. The air-con worked and was left running. We then switched on both pumps, I expected the Honda to stall, it revved-up a little but didn't miss a beat. At the same time the electrician and I were conversing at normal voice standing right by the generator. Indoors it was a gentle burbling hum.
One company given details of our needs as above offered 20-22kW non inverted generators with prices up to over $14,000. So the Honda EU70 at less than half that capacity and price to quietly take this load in its stride was most impressive and simply amazing. I have several other Honda powered machines, all of them including a fire pump which is run every two years, start first or on a bad day, second pull.
When comparing generator inverters look at and compare the engine capacity (cc); engine performance (engine torque and kW output) and speed. Some claiming similar output to the Honda have nearly 30% less capacity and most are not fuel injected so use more fuel. Some generator inverters run at double the (rpm) speed so more engine wear, much more noise and again thirstier on fuel consumption.
We have no need to run all this equipment at the same time in fact we never expected either...
