What the Power Box can do for you

The hybridization of the diesel generator with an xelectrix energy storage makes it possible to optimize generator operation by making it run in a more efficient power load band. This leads to more efficient combustion of diesel fuel and thus a reduction in CO₂ / NO_X emissions, as well as, burning less less diesel to produce one kWh of power . The excess energy being produced by the diesel generator is not going to wast – it is used to charge the batteries of the XPB unit, and when these batteries are full, the diesel generator is automatically switched off. The energy storage also serves as a buffer to absorbs peak loads and thus further reduce emissions.

The operation of diesel generators can be very noisy and cause noise pollution. It is well known that noise levels above 70 decibels can cause hearing damage and noise levels from diesel generators can often be much higher than 70 decibels. Hybridization with the Power Box can help to reduce or completely avoid the operation of the generator if the energy storage is sufficiently charged. Within a city, this protects the residents.

The hybridization of the diesel generator with an energy storage unit increases the reliability of the power supply system. The energy storage can serve as a buffer to cushion peak loads and avoid failures of the diesel generator.

Response time is an important factor in power delivery, especially when powering critical loads. While diesel generators are an established technology, energy storage has become an attractive alternative in recent years. One of the key differences between these two technologies is their response time to changing loads.

In general, it takes minutes for a diesel generator to run stably after a load change or when operating in a backup function. In comparison, our Power Box can react to changes in the load in a few milliseconds and adjust the power accordingly. It is also in ancillary or grid services that this speed is important. The xelectrix Power Boxes have the ability to respond to frequency alarm signals with full inverter power in below 300 ms.

The Peak Power Boost is used when the generator does not supply enough electricity for the consumers required. For example, when a tower crane is to be put into operation on a construction site for a short time.

The Power Box can sum up all power sources with the stored energy to cover the higher power required (example: ~ 35 kW diesel generator + 35 kW Power Box inverter power = 70 kW output).

The Power Box is equipped with a large number of standardized interfaces, which can also be adapted to customer requirements. Our Unlimited M10 and the M20 is particularly advantageous for construction sites as they can be installed quickly and easily.

The xelectrix energy storage devices are maintenance-free, which makes them attractive for construction machinery rentals. Apart from that, a smaller diesel generator can be rented with the Peak Power Boost function, since the generator does not necessarily have to be designed for the highest expected load.

By offering hybridized diesel generators, construction machinery rental can open up a new business area and appeal to customers who are interested in more environmentally friendly and efficient solutions.
