If you were looking for a permanent generator to provide for your full power needs (not having to pick and choose between circuits), what size would you go with? Currently, a single 2,000 watts Honda inverter will provide the power needs we consume, minus one refrigerator / freezer with the "old technology" compressor. If I were to run both Honda EU20i's simultaneously, even that refrigerator / freezer could be powered. Truth be told, I didn't take one thing into consideration when I purchased these fancy Honda generators. That is, exactly how frequently we may start having power cuts. Well, the electricity gods knew when we moved here. Over time, the power cuts have slowly been growing longer and more frequently. Personally, I have grown tired of pulling out a portable generator, starting it, connecting it to the plug I installed in the main panel for it, and then throwing the double pole knife switch. Then, after mains power has been reconnected, doing that in the opposite order every time we have a power cut. We have them too often. It's even less fun in a full monsoon rain. For me, it is long past time for emergency power to automatically come online when needed and automatically switch off when no longer needed, without me having to do anything. The straw that broke the camel's back: I had to wait through a 4.5 hours power cut for the mains to come on the other night, before I could switch back to mains and power off the little inverter. So, I am not exactly happy. But, at least it wasn't raining. If I had a diesel generator with an automatic transfer switch, I could go to sleep knowing it will automatically switch over and power down, all while I sleep. At the time I was looking at the Honda Inverter (EU20i) generators ($888 each), I also priced a Denyo 15kva (DCA-15LSK) diesel powered generator ($3,500 USD each). This was about January of 2017. Hindsight being what it is, I am reconsidering buying a Denyo. They must be the cat's meow. I rarely (if ever?) have seen a bank building here without a Denyo unit attached to it. I'm just not sure if I should still consider the 15kva, or if I should go with a smaller unit. Smaller units are available in country - 13kva, 10kva, and 6kva. I just want it to power everything here, business as usual, during a power cut. I do not want to wire "emergency power only" circuits. I want one automatic transfer switch to disconnect from the mains, while powering the entire farm until the mains come back online. The one real difference among them is, all generators I listed above, with the exception of one, are Swirl Chambered. The 13kva (DCA-13LSY) is Direct Injected. Not sure if, or how much of a difference that makes between diesel fired generators. But, it does appear to be the most efficient unit, of those I am looking at. Efficient is good. So, if I may bother you good folk, how much additional power would you calculate you need, if sizing a generator for your entire property?
