Emergency power generators and power generators: Service, rental, sales, and manufacturing

Emergency power generators, power generators, and backup power systems have been the business of HO-MA Notstrom for over 30 years.

We are TÜV-certified and operate in four areas of expertise. In the service sector, our highly specialized emergency power technicians take care of regular maintenance and ensure the quickest possible troubleshooting for engine and control systems of backup power systems. With our 24-hour emergency service, we guarantee our customers maximum availability of their emergency power generators. For rentals, we have over 2,000 power generators available nationwide, ranging from 15 to 2,000 kVA. Our range of emergency power technology is completed by lighting towers, fuel tanks, distribution panels, cables, as well as transformers and load resistors, which can also be rented from us.

We operate throughout Germany. The sale of power generators, lighting towers, and particulate filters is also part of our range of services.

You can directly purchase mobile power generators with capacities ranging from 1 to 15 kVA, PTO generators and water pumps from us online. For larger power generators in canopy or container construction with up to 2,500 kVA, you can freely configure them using the corresponding inquiry form. We will get back to you as soon as possible with a suitable offer. As an official dealer of well-known manufacturers, we always offer a top price-performance ratio. Additionally, feel free to contact us if you require customized container generators, open power generators tailored to your specifications, or precisely manufactured particulate filters for your system. Smaller backup power systems can be ordered directly from our online shop.
