...And are you SURE you need the amperage that an 803 puts out? Thats always the question I ask potential folks looking at machines. You need to size a machine to its REALISTIC use. Generac and all the others have done a great job convincing people that bigger is better. Its just not true when it comes to diesel gensets.
Exactly! One's own intended usage is what is relevant. Are you single, a couple, or a family of eight? Is it just for emergency power outage backup in order to just get by? Scenario #1: Running refrigerators/freezers, well pump, sewage pump, lights, small appliances, blower motors, with some
gas appliances? Or are you "
all electric" and are needing to run a full electric house load? Scenario #2: HVAC, electric hot water, electric cook top, plus typical electrical appliances, etc?
Before deciding on what size genset to buy one needs to do a
home energy audit. Most appliances have electrical stickers/placards stating their electrical consumption. Make a list and add it all up, factoring in that most of them will not be used simultaneously at the same time. However, if you want to allow for that (large family scenario) you can. Remember, that most military gensets are rated to run at ~125% output for an hour (with altitude factors).
If you size your genset appropriately you will thank yourself when your faced with an extended multiple day outage and fuel reserves become a factor.
