How big of a generator do I need?
How many watts would it take to run a small cabin with just basic lights, mini fridge, stove, maybe a small tv…? I was thinking a 6000 watt diesel generator….would running it every day ruin it?
That should probably be a big enough generator to run what ur describing…The only problem you could have is with the stove. You may have to run it by itself, depending on its size some stoves can pull alot of amps. As far as running it everyday, a diesel engine is made to run pretty much non stop, that is the advantage of a diesel over a gas engine…Hope this helps, any other questions feel free to email or message me…Doug

An electrical power system consists of identical diesel generators?
An electrical power system consists of identical diesel generators, each generator. Has a constant failure rate of 0.5 per year.
Calculate the reliability of the following arrangement-three months after the initial commissioning date.
1. Only one generator operating.
2. Only generator operating, one generator standby.
3. One generator operating, two generators standby.
Some basic stats.
Assumptions:
each of the cases are independent problems.
The constant .5/year failure rate is linear throughout the year (normally a failure rate curve of machinery is like a V w/ a chopped off left side.
P(Failure @ 3 Months) = 0.5 / 4 = .125
1) P(1 failure @ 3 months) = 0.125
1-P(failure) = reliability = 1-.125 = 0.875
2) P(First fails AND seconds fails) = 0.125 * 0.125 = 0.015625
Reliability = 1 - .015625 = .984375
3) P(First fails AND Second fails AND Third fails) = 0.125* 0.125 * 0.125 = 0.00193
Reliability = 1 - 0.00193 = 0.998047
