Expert Insights on Power Solutions and Generator Technology

A private label generator factory builds two kinds of part, and only one of them survives your model’s retirement. The engine, the alternator and the controller have their own global supply chains, so they remain serviceable long after your badge stops appearing on new units. The canopy, the plate, the loom as built, the brackets and the manual...

The discount is not the margin. A generator manufacturer for distributors can offer the lowest unit price on the table and still leave you a thinner business than the factory quoting 8% more, because what you keep is decided by five cost lines and the discount touches only one of them. Most distributors find that out in their second year, after the...

A custom branded generator supplier can put your name on the set plate, the canopy, the control panel, the manual and the carton. It can’t put your name over the engine’s emissions label, and that is a legal line rather than a design preference. Most buyers discover this after they’ve sent a logo file and a colour code, and expected...

Sourcing from an OEM diesel generator manufacturer in China puts two names on the machine. The factory’s name goes inside, on the engine, the alternator and the control panel. Your name goes on the outside, on the nameplate. A set actually carries three plates, from three different makers, and only one of them is yours. Only one name carries the...

A generator has no correct phase rotation. The load does. Generator phase rotation is the order in which the three output voltages reach their peaks, and that order decides which direction a three-phase motor turns. Reverse two of the three conductors and the motor runs the other way. What makes this a trap rather than a simple mistake is that a reversed...

Generator single phasing is usually described as something that happens to a motor. It can start at the generator too, and when it does, almost nothing on site behaves the way the guides say it should. A phase can be lost inside the set or between the set and the load: at an alternator terminal, a breaker pole, a fuse, a contactor, a cable joint. The...

A generator nameplate isn’t one plate. A packaged generating set carries three, from three different manufacturers, and the one you’re reading may not be the one that answers your question. That’s the part every guide skips. They list the fields in alphabetical order and never say the fields live on separate pieces of metal, put there...

Three-phase generator load balancing has no single limit. It has two, they apply to different equipment, and they are measured in different quantities. That’s why the numbers you find contradict each other. One source says 10%. Another says 1%. A third says 10 to 15%. All three are real. Reading any of them against the wrong reading on your meter...

Three-phase generator voltage is normally quoted as a single figure: 400V line-to-line with 230V line-to-neutral on a 50 Hz system, or 480V with 277V on 60 Hz. Those numbers are correct. On their own they’re also misleading, because they’re labels rather than limits. There is no such thing as a 400V supply. Nobody generates at 400V, and...

What equipment needs a three-phase generator? Mostly anything motor-driven. Above a certain size, a motor is simply built as a three-phase machine, and whatever it drives inherits that. But the honest answer isn’t a list. It’s three numbers, and they disagree by a factor of fifteen. Here’s why nobody gives you a straight answer: two...
