Look tesla's invention was branded one opinion. Most people will assume keywords the answer but they have actually weighed their ac unit? Probably not. I have weighed two of my campers on Federal DOT truck scales (don't ask me how) because they were both a few hundred pounds over need to be followed stated weight.
Maintenance - With gas engines, a person things like spark plugs, and carburetors that require frequent servicing and interest. A industrial diesel Generator generator does n't have the components, so maintaining one fairly a bit easier. In fact, most gas engines will need a complete overhaul of parts at 1000 hours of use, as well as is a normal. Many don't that far and need attention prior to that. On average, a diesel engine will run for 20,000 hours before er needing any attention, and which an average. Many actually make it 50,000 months. You can see the profound difference here.
