TX is our basic entry level series. It uses quality components from around the world with main components coming from Europe. It is a 2-pole generator (2 sets of windings) so power output has a slight fluctuation. This is similar to most portable consumer generators and some stationary units, and in most cases this is suitable for small to moderate sized household or homestead/small farm requirements. We have heard anecdotal info that some sensitive computer circuitry is not compatible with this minor fluctuation so potential customer should be aware that this may pose an issue if said computer systems are present and wish to be run or are a must during an outage. The TX series is also not capable of handling any electric motors in excess of 2HP. So, if any well pumps, heat systems, feed systems, or refrigeration, has motors larger, then the KR or QC should be selected. Refer to - https://baumalight.com/product/generators/tx-series
The KR is a 4 pole (4 windings) unit and it was introduced several years ago and in both quality, and ability, it is the same as a QC generator, the only difference is that the main components come from Europe. The key features are exactly the same as the more expensive QC series. It was initially designed towards dairy and farm/light industrial applications, where sensitive computers may be present. Its actual application range is broad and it is often the best choice for value but is often overlooked as being “too big for the tractor”, which in some cases is an error and I’ll address that further below.

The QC is our original model with 4 pole windings. This unit is available in a broad range of KW and voltages/phases and its main component is made in North America for most of the models, some also come from Europe. Although it’s available in a multitude of sizes, it’s mainly for high voltage output or 3 phase application. Refer to - https://baumalight.com/product/generators/kr-qc-series
Horsepower ratings- It is easier to run a larger generator at 50% load than it is to run a smaller unit at 100% load. An example where this may be a factor is – A customer who requires 12 or 18KW and would like a 4 pole generator but only has 25hp, would perhaps be best off with a KR30 (running at 50% load). It’s a better value than a QC 19 for example and would allow for upgrades in tractor and allow for increased demand in the future. It will not be too much for the tractor in any way and simply will only deliver 50% load. The QC is always an option for the discerning customer. In a nutshell- If a customer wants to carry on during a hydro outage or interruption as if nothing ever happened then a 4 pole (KR or QC) should be selected in either the appropriate KW size or larger. If customer has no limiting factors mentioned in the TX description above, or is prepared to limit his consumption or sequence some of his demand then the TX is adequate in most cases and circumstances of light to moderate consumption. When in doubt- go bigger and go 4 pole (KR or QC). It’s easier than dealing with a situation where the Generator is too small or wouldn’t power certain items.
