Generator undervoltage is usually caused by overload, low engine speed, fuel starvation, a regulator or excitation fault, excessive voltage drop or an incorrect connection. Treat it as a system problem, not an invitation … Read more
A 20kW standby generator can run most major loads in many homes, but it will not automatically run every circuit at once. Electric heat, large air conditioners, well pumps, water heaters, ranges, dryers … Read more
A generator does not have a fixed expiration date. Its useful life depends more on engine hours, load, maintenance, fuel quality, storage and corrosion than on the year printed on the nameplate. A … Read more

An air conditioner can need several times its running power for a fraction of a second when the compressor starts. That startup demand, not the cooling tonnage alone, determines whether a generator will … Read more
Synthetic oil can improve cold starts and high-temperature protection, but the label alone does not make it right for every generator. Use it only when the owner’s manual permits the oil viscosity and … Read more
A generator may keep its starting battery charged, but many portable models will not do it automatically just because the engine is running. The answer depends on the generator’s charging circuit, not its … Read more
Do not start a generator by spinning its flywheel nut with a power drill. If the pull cord fails, use a manufacturer-approved electric-start system or repair the recoil starter before running the engine. … Read more
